A frequent question I see being asked is how Cosmos, Polkadot and Avalanche compare? Whilst there are similarities there are also a lot of differences. This article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important.

CosmosCosmos is a heterogeneous network of many independent parallel blockchains, each powered by classical BFT consensus algorithms like Tendermint. Developers can easily build custom application specific blockchains, called Zones, through the Cosmos SDK framework. These Zones connect to Hubs, which are specifically designed to connect zones together.
The vision of Cosmos is to have thousands of Zones and Hubs that are Interoperable through the Inter-Blockchain Communication Protocol (IBC). Cosmos can also connect to other systems through peg zones, which are specifically designed zones that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Cosmos does not use Sharding with each Zone and Hub being sovereign with their own validator set.

PolkadotPolkadot is a heterogeneous blockchain protocol that connects multiple specialised blockchains into one unified network. It achieves scalability through a sharding infrastructure with multiple blockchains running in parallel, called parachains, that connect to a central chain called the Relay Chain. Developers can easily build custom application specific parachains through the Substrate development framework.
The relay chain validates the state transition of connected parachains, providing shared state across the entire ecosystem. If the Relay Chain must revert for any reason, then all of the parachains would also revert. This is to ensure that the validity of the entire system can persist, and no individual part is corruptible. The shared state makes it so that the trust assumptions when using parachains are only those of the Relay Chain validator set, and no other. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. The hope is to have 100 parachains connect to the relay chain.

AvalancheAvalanche is a platform of platforms, ultimately consisting of thousands of subnets to form a heterogeneous interoperable network of many blockchains, that takes advantage of the revolutionary Avalanche Consensus protocols to provide a secure, globally distributed, interoperable and trustless framework offering unprecedented decentralisation whilst being able to comply with regulatory requirements.
Avalanche allows anyone to create their own tailor-made application specific blockchains, supporting multiple custom virtual machines such as EVM and WASM and written in popular languages like Go (with others coming in the future) rather than lightly used, poorly-understood languages like Solidity. This virtual machine can then be deployed on a custom blockchain network, called a subnet, which consist of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance.
Avalanche was built with serving financial markets in mind. It has native support for easily creating and trading digital smart assets with complex custom rule sets that define how the asset is handled and traded to ensure regulatory compliance can be met. Interoperability is enabled between blockchains within a subnet as well as between subnets. Like Cosmos and Polkadot, Avalanche is also able to connect to other systems through bridges, through custom virtual machines made to interact with another ecosystem such as Ethereum and Bitcoin.

Comparison between Cosmos, Polkadot and AvalancheA frequent question I see being asked is how Cosmos, Polkadot and Avalanche compare? Whilst there are similarities there are also a lot of differences. This article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions. I want to stress that it’s not a case of one platform being the killer of all other platforms, far from it. There won’t be one platform to rule them all, and too often the tribalism has plagued this space. Blockchains are going to completely revolutionise most industries and have a profound effect on the world we know today. It’s still very early in this space with most adoption limited to speculation and trading mainly due to the limitations of Blockchain and current iteration of Ethereum, which all three of these platforms hope to address. For those who just want a quick summary see the image at the bottom of the article. With that said let’s have a look
CosmosEach Zone and Hub in Cosmos is capable of up to around 1000 transactions per second with bandwidth being the bottleneck in consensus. Cosmos aims to have thousands of Zones and Hubs all connected through IBC. There is no limit on the number of Zones / Hubs that can be created
PolkadotParachains in Polkadot are also capable of up to around 1500 transactions per second. A portion of the parachain slots on the Relay Chain will be designated as part of the parathread pool, the performance of a parachain is split between many parathreads offering lower performance and compete amongst themselves in a per-block auction to have their transactions included in the next relay chain block. The number of parachains is limited by the number of validators on the relay chain, they hope to be able to achieve 100 parachains.
AvalancheAvalanche is capable of around 4500 transactions per second per subnet, this is based on modest hardware requirements to ensure maximum decentralisation of just 2 CPU cores and 4 GB of Memory and with a validator size of over 2,000 nodes. Performance is CPU-bound and if higher performance is required then more specialised subnets can be created with higher minimum requirements to be able to achieve 10,000 tps+ in a subnet. Avalanche aims to have thousands of subnets (each with multiple virtual machines / blockchains) all interoperable with each other. There is no limit on the number of Subnets that can be created.
ResultsAll three platforms offer vastly superior performance to the likes of Bitcoin and Ethereum 1.0. Avalanche with its higher transactions per second, no limit on the number of subnets / blockchains that can be created and the consensus can scale to potentially millions of validators all participating in consensus scores ✅✅✅. Polkadot claims to offer more tps than cosmos, but is limited to the number of parachains (around 100) whereas with Cosmos there is no limit on the number of hubs / zones that can be created. Cosmos is limited to a fairly small validator size of around 200 before performance degrades whereas Polkadot hopes to be able to reach 1000 validators in the relay chain (albeit only a small number of validators are assigned to each parachain). Thus Cosmos and Polkadot scores ✅✅
CosmosTendermint consensus is limited to around 200 validators before performance starts to degrade. Whilst there is the Cosmos Hub it is one of many hubs in the network and there is no central hub or limit on the number of zones / hubs that can be created.
PolkadotPolkadot has 1000 validators in the relay chain and these are split up into a small number that validate each parachain (minimum of 14). The relay chain is a central point of failure as all parachains connect to it and the number of parachains is limited depending on the number of validators (they hope to achieve 100 parachains). Due to the limited number of parachain slots available, significant sums of DOT will need to be purchased to win an auction to lease the slot for up to 24 months at a time. Thus likely to lead to only those with enough funds to secure a parachain slot. Parathreads are however an alternative for those that require less and more varied performance for those that can’t secure a parachain slot.
AvalancheAvalanche consensus scan scale to tens of thousands of validators, even potentially millions of validators all participating in consensus through repeated sub-sampling. The more validators, the faster the network becomes as the load is split between them. There are modest hardware requirements so anyone can run a node and there is no limit on the number of subnets / virtual machines that can be created.
ResultsAvalanche offers unparalleled decentralisation using its revolutionary consensus protocols that can scale to millions of validators all participating in consensus at the same time. There is no limit to the number of subnets and virtual machines that can be created, and they can be created by anyone for a small fee, it scores ✅✅✅. Cosmos is limited to 200 validators but no limit on the number of zones / hubs that can be created, which anyone can create and scores ✅✅. Polkadot hopes to accommodate 1000 validators in the relay chain (albeit these are split amongst each of the parachains). The number of parachains is limited and maybe cost prohibitive for many and the relay chain is a ultimately a single point of failure. Whilst definitely not saying it’s centralised and it is more decentralised than many others, just in comparison between the three, it scores ✅
CosmosTendermint consensus used in Cosmos reaches finality within 6 seconds. Cosmos consists of many Zones and Hubs that connect to each other. Communication between 2 zones could pass through many hubs along the way, thus also can contribute to latency times depending on the path taken as explained in part two of the articles on Cosmos. It doesn’t need to wait for an extended period of time with risk of rollbacks.
PolkadotPolkadot provides a Hybrid consensus protocol consisting of Block producing protocol, BABE, and then a finality gadget called GRANDPA that works to agree on a chain, out of many possible forks, by following some simpler fork choice rule. Rather than voting on every block, instead it reaches agreements on chains. As soon as more than 2/3 of validators attest to a chain containing a certain block, all blocks leading up to that one are finalized at once.
If an invalid block is detected after it has been finalised then the relay chain would need to be reverted along with every parachain. This is particularly important when connecting to external blockchains as those don’t share the state of the relay chain and thus can’t be rolled back. The longer the time period, the more secure the network is, as there is more time for additional checks to be performed and reported but at the expense of finality. Finality is reached within 60 seconds between parachains but for external ecosystems like Ethereum their state obviously can’t be rolled back like a parachain and so finality will need to be much longer (60 minutes was suggested in the whitepaper) and discussed in more detail in part three
AvalancheAvalanche consensus achieves finality within 3 seconds, with most happening sub 1 second, immutable and completely irreversible. Any subnet can connect directly to another without having to go through multiple hops and any VM can talk to another VM within the same subnet as well as external subnets. It doesn’t need to wait for an extended period of time with risk of rollbacks.
ResultsWith regards to performance far too much emphasis is just put on tps as a metric, the other equally important metric, if not more important with regards to finance is latency. Throughput measures the amount of data at any given time that it can handle whereas latency is the amount of time it takes to perform an action. It’s pointless saying you can process more transactions per second than VISA when it takes 60 seconds for a transaction to complete. Low latency also greatly increases general usability and customer satisfaction, nowadays everyone expects card payments, online payments to happen instantly. Avalanche achieves the best results scoring ✅✅✅, Cosmos with comes in second with 6 second finality ✅✅ and Polkadot with 60 second finality (which may be 60 minutes for external blockchains) scores ✅
CosmosEvery Zone and Hub in Cosmos has their own validator set and different trust assumptions. Cosmos are researching a shared security model where a Hub can validate the state of connected zones for a fee but not released yet. Once available this will make shared security optional rather than mandatory.
PolkadotShared Security is mandatory with Polkadot which uses a Shared State infrastructure between the Relay Chain and all of the connected parachains. If the Relay Chain must revert for any reason, then all of the parachains would also revert. Every parachain makes the same trust assumptions, and as such the relay chain validates state transition and enables seamless interoperability between them. In return for this benefit, they have to purchase DOT and win an auction for one of the available parachain slots.
However, parachains can’t just rely on the relay chain for their security, they will also need to implement censorship resistance measures and utilise proof of work / proof of stake for each parachain as well as discussed in part three, thus parachains can’t just rely on the security of the relay chain, they need to ensure sybil resistance mechanisms using POW and POS are implemented on the parachain as well.
AvalancheA subnet in Avalanche consists of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance. So unlike in Cosmos where each zone / hub has their own validators, A subnet can validate a single or many virtual machines / blockchains with a single validator set. Shared security is optional
ResultsShared security is mandatory in polkadot and a key design decision in its infrastructure. The relay chain validates the state transition of all connected parachains and thus scores ✅✅✅. Subnets in Avalanche can validate state of either a single or many virtual machines. Each subnet can have their own token and shares a validator set, where complex rulesets can be configured to meet regulatory compliance. It scores ✅ ✅. Every Zone and Hub in cosmos has their own validator set / token but research is underway to have the hub validate the state transition of connected zones, but as this is still early in the research phase scores ✅ for now.
CosmosThe Cosmos project started in 2016 with an ICO held in April 2017. There are currently around 50 projects building on the Cosmos SDK with a full list can be seen here and filtering for Cosmos SDK . Not all of the projects will necessarily connect using native cosmos sdk and IBC and some have forked parts of the Cosmos SDK and utilise the tendermint consensus such as Binance Chain but have said they will connect in the future.
PolkadotThe Polkadot project started in 2016 with an ICO held in October 2017. There are currently around 70 projects building on Substrate and a full list can be seen here and filtering for Substrate Based. Like with Cosmos not all projects built using substrate will necessarily connect to Polkadot and parachains or parathreads aren’t currently implemented in either the Live or Test network (Kusama) as of the time of this writing.
AvalancheAvalanche in comparison started much later with Ava Labs being founded in 2018. Avalanche held it’s ICO in July 2020. Due to lot shorter time it has been in development, the number of projects confirmed are smaller with around 14 projects currently building on Avalanche. Due to the customisability of the platform though, many virtual machines can be used within a subnet making the process incredibly easy to port projects over. As an example, it will launch with the Ethereum Virtual Machine which enables byte for byte compatibility and all the tooling like Metamask, Truffle etc. will work, so projects can easily move over to benefit from the performance, decentralisation and low gas fees offered. In the future Cosmos and Substrate virtual machines could be implemented on Avalanche.
ResultsWhilst it’s still early for all 3 projects (and the entire blockchain space as a whole), there is currently more projects confirmed to be building on Cosmos and Polkadot, mostly due to their longer time in development. Whilst Cosmos has fewer projects, zones are implemented compared to Polkadot which doesn’t currently have parachains. IBC to connect zones and hubs together is due to launch Q2 2021, thus both score ✅✅✅. Avalanche has been in development for a lot shorter time period, but is launching with an impressive feature set right from the start with ability to create subnets, VMs, assets, NFTs, permissioned and permissionless blockchains, cross chain atomic swaps within a subnet, smart contracts, bridge to Ethereum etc. Applications can easily port over from other platforms and use all the existing tooling such as Metamask / Truffle etc but benefit from the performance, decentralisation and low gas fees offered. Currently though just based on the number of projects in comparison it scores ✅.
CosmosCosmos enables permissioned and permissionless zones which can connect to each other with the ability to have full control over who validates the blockchain. For permissionless zones each zone / hub can have their own token and they are in control who validates.
PolkadotWith polkadot the state transition is performed by a small randomly selected assigned group of validators from the relay chain plus with the possibility that state is rolled back if an invalid transaction of any of the other parachains is found. This may pose a problem for enterprises that need complete control over who performs validation for regulatory reasons. In addition due to the limited number of parachain slots available Enterprises would have to acquire and lock up large amounts of a highly volatile asset (DOT) and have the possibility that they are outbid in future auctions and find they no longer can have their parachain validated and parathreads don’t provide the guaranteed performance requirements for the application to function.
AvalancheAvalanche enables permissioned and permissionless subnets and complex rulesets can be configured to meet regulatory compliance. For example a subnet can be created where its mandatory that all validators are from a certain legal jurisdiction, or they hold a specific license and regulated by the SEC etc. Subnets are also able to scale to tens of thousands of validators, and even potentially millions of nodes, all participating in consensus so every enterprise can run their own node rather than only a small amount. Enterprises don’t have to hold large amounts of a highly volatile asset, but instead pay a fee in AVAX for the creation of the subnets and blockchains which is burnt.
ResultsAvalanche provides the customisability to run private permissioned blockchains as well as permissionless where the enterprise is in control over who validates the blockchain, with the ability to use complex rulesets to meet regulatory compliance, thus scores ✅✅✅. Cosmos is also able to run permissioned and permissionless zones / hubs so enterprises have full control over who validates a blockchain and scores ✅✅. Polkadot requires locking up large amounts of a highly volatile asset with the possibility of being outbid by competitors and being unable to run the application if the guaranteed performance is required and having to migrate away. The relay chain validates the state transition and can roll back the parachain should an invalid block be detected on another parachain, thus scores ✅.
CosmosCosmos will connect Hubs and Zones together through its IBC protocol (due to release in Q1 2020). Connecting to blockchains outside of the Cosmos ecosystem would either require the connected blockchain to fork their code to implement IBC or more likely a custom “Peg Zone” will be created specific to work with a particular blockchain it’s trying to bridge to such as Ethereum etc. Each Zone and Hub has different trust levels and connectivity between 2 zones can have different trust depending on which path it takes (this is discussed more in this article). Finality time is low at 6 seconds, but depending on the number of hops, this can increase significantly.
PolkadotPolkadot’s shared state means each parachain that connects shares the same trust assumptions, of the relay chain validators and that if one blockchain needs to be reverted, all of them will need to be reverted. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Finality time between parachains is around 60 seconds, but longer will be needed (initial figures of 60 minutes in the whitepaper) for connecting to external blockchains. Thus limiting the appeal of connecting two external ecosystems together through Polkadot. Polkadot is also limited in the number of Parachain slots available, thus limiting the amount of blockchains that can be bridged. Parathreads could be used for lower performance bridges, but the speed of future blockchains is only going to increase.
AvalancheA subnet can validate multiple virtual machines / blockchains and all blockchains within a subnet share the same trust assumptions / validator set, enabling cross chain interoperability. Interoperability is also possible between any other subnet, with the hope Avalanche will consist of thousands of subnets. Each subnet may have a different trust level, but as the primary network consists of all validators then this can be used as a source of trust if required. As Avalanche supports many virtual machines, bridges to other ecosystems are created by running the connected virtual machine. There will be an Ethereum bridge using the EVM shortly after mainnet. Finality time is much faster at sub 3 seconds (with most happening under 1 second) with no chance of rolling back so more appealing when connecting to external blockchains.
ResultsAll 3 systems are able to perform interoperability within their ecosystem and transfer assets as well as data, as well as use bridges to connect to external blockchains. Cosmos has different trust levels between its zones and hubs and can create issues depending on which path it takes and additional latency added. Polkadot provides the same trust assumptions for all connected parachains but has long finality and limited number of parachain slots available. Avalanche provides the same trust assumptions for all blockchains within a subnet, and different trust levels between subnets. However due to the primary network consisting of all validators it can be used for trust. Avalanche also has a much faster finality time with no limitation on the number of blockchains / subnets / bridges that can be created. Overall all three blockchains excel with interoperability within their ecosystem and each score ✅✅.
CosmosThe ATOM token is the native token for the Cosmos Hub. It is commonly mistaken by people that think it’s the token used throughout the cosmos ecosystem, whereas it’s just used for one of many hubs in Cosmos, each with their own token. Currently ATOM has little utility as IBC isn’t released and has no connections to other zones / hubs. Once IBC is released zones may prefer to connect to a different hub instead and so ATOM is not used. ATOM isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for ATOM as of the time of this writing is $1 Billion with 203 million circulating supply. Rewards can be earnt through staking to offset the dilution caused by inflation. Delegators can also get slashed and lose a portion of their ATOM should the validator misbehave.
PolkadotPolkadot’s native token is DOT and it’s used to secure the Relay Chain. Each parachain needs to acquire sufficient DOT to win an auction on an available parachain lease period of up to 24 months at a time. Parathreads have a fixed fee for registration that would realistically be much lower than the cost of acquiring a parachain slot and compete with other parathreads in a per-block auction to have their transactions included in the next relay chain block. DOT isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for DOT as of the time of this writing is $4.4 Billion with 852 million circulating supply. Delegators can also get slashed and lose their DOT (potentially 100% of their DOT for serious attacks) should the validator misbehave.
AvalancheAVAX is the native token for the primary network in Avalanche. Every validator of any subnet also has to validate the primary network and stake a minimum of 2000 AVAX. There is no limit to the number of validators like other consensus methods then this can cater for tens of thousands even potentially millions of validators. As every validator validates the primary network, this can be a source of trust for interoperability between subnets as well as connecting to other ecosystems, thus increasing amount of transaction fees of AVAX. There is no slashing in Avalanche, so there is no risk to lose your AVAX when selecting a validator, instead rewards earnt for staking can be slashed should the validator misbehave. Because Avalanche doesn’t have direct slashing, it is technically possible for someone to both stake AND deliver tokens for something like a flash loan, under the invariant that all tokens that are staked are returned, thus being able to make profit with staked tokens outside of staking itself.
There will also be a separate subnet for Athereum which is a ‘spoon,’ or friendly fork, of Ethereum, which benefits from the Avalanche consensus protocol and applications in the Ethereum ecosystem. It’s native token ATH will be airdropped to ETH holders as well as potentially AVAX holders as well. This can be done for other blockchains as well.
Transaction fees on the primary network for all 3 of the blockchains as well as subscription fees for creating a subnet and blockchain are paid in AVAX and are burnt, creating deflationary pressure. AVAX is a fixed capped supply of 720 million tokens, creating scarcity rather than an unlimited supply which continuously increase of tokens at a compounded rate each year like others. Initially there will be 360 tokens minted at Mainnet with vesting periods between 1 and 10 years, with tokens gradually unlocking each quarter. The Circulating supply is 24.5 million AVAX with tokens gradually released each quater. The current market cap of AVAX is around $100 million.
ResultsAvalanche’s AVAX with its fixed capped supply, deflationary pressure, very strong utility, potential to receive air drops and low market cap, means it scores ✅✅✅. Polkadot’s DOT also has very strong utility with the need for auctions to acquire parachain slots, but has no deflationary mechanisms, no fixed capped supply and already valued at $3.8 billion, therefore scores ✅✅. Cosmos’s ATOM token is only for the Cosmos Hub, of which there will be many hubs in the ecosystem and has very little utility currently. (this may improve once IBC is released and if Cosmos hub actually becomes the hub that people want to connect to and not something like Binance instead. There is no fixed capped supply and currently valued at $1.1 Billion, so scores ✅.
All three are excellent projects and have similarities as well as many differences. Just to reiterate this article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions, you may have different criteria which is important to you, and score them differently. There won’t be one platform to rule them all however, with some uses cases better suited to one platform over another, and it’s not a zero-sum game. Blockchain is going to completely revolutionize industries and the Internet itself. The more projects researching and delivering breakthrough technology the better, each learning from each other and pushing each other to reach that goal earlier. The current market is a tiny speck of what’s in store in terms of value and adoption and it’s going to be exciting to watch it unfold.

We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.
SolutionsSyscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
Syscoin + Matic IntegrationMatic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.
Proving Performance & Cost SavingsOur POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014
The demonstration was executed using this tool. The results can be seen in the following blocks:
It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.
Cost SavingsTotal cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

HOWTO: Setup an Agent
Developer & User Diligence
Trade-offThe Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.
CostEthereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.
Z-DAGZero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).
APISyscoin-js provides tooling for all Syscoin Core RPCs including interactivity with Z-DAG.

Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana
Trade-offZ-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

The Search Engine Giant Had Switched Stances, As Prior Entering Into A Partnership Google Distanced Themselves From The Blockchain Sector
One of the biggest tech companies to date, Google, struck the crypto community by announcing a partnership between its Cloud subsidiary and the blockchain video streaming company Theta Labs. Apart from enabling its users to create nodes on Theta’s network, Google Cloud would also act as a note, which would validate data transactions for whole Europe.
However, this is the first step for the search engine giant, as Google remained somewhat negative about the trends and advancements in the crypto sector. “The partnership is just a baby step towards entering the blockchain space, as we currently operate with many crypto customers,” Allen Day, one of Google’s Developer Advocates stated.
“Furthermore, we already made public data from Blockchain, Ethereum, as well as six other crypto project via out dataset program. The partnership with Theta is a natural consequence.” Day added.
For Google, becoming a transaction validator is not such a great achievement, but Theta’s game might receive a massive boost. Theta Labs aims at lightening the load on the centralized data centers like those of Netflix and YouTube facilitate to keep their services up and running. For every video request, centralized data centers execute a series of commands, often followed by a vast download of information. Theta’s network is decentralized, meaning data packages would be evenly distributed across the entire network and only small bits of information would travel through it.
Essentially, Theta’s TV app enables common Android-based TV’s to act as server nodes, distributing content to other network participants, without the need of hundreds of downloads from the main server.
However, Theta’s innovation consists of enabling customers to receive bonuses, when not using their Internet bandwidth for video content streaming. According to Sandvine, over 15% of the global Internet traffic amid the COVID-19 lockdown went directly to Google’s YouTube, followed closely by Netflix, which recorded little over 10%. Facebook and Instagram combined mark less than 10% internet traffic from February 1 to April 19, 2020.
Theta’s biggest achievement would be the possible YouTube integration. With costs for deploying and managing enormous centralized content delivery networks (CDNs) like those of Netflix, for example, Theta seems as a viable option for content management services providers to streamline their efficiency.
“Most of the modern data centers are designed around ensuring peak performance, which occurs no more than 1% of the operational time. Building such infrastructure is costly, and you can rarely plan for a peak, ” Theta’s CEO and co-founder Mitch Liu stated.
Google’s partnership with Theta turns the search engine giant into the fifth external validator for Theta’s service. Other validators include Binance, Samsung, Gumi Cryptos, as well as Blockchain Ventures.
Meanwhile, Theta also launched a 2.0 version of their mainnet, improving scalability and security. Also, Theta’s incorporating a multi-byzantine fault-tolerant (Multi-BFT) consensus algorithm, which enables guardian nodes to help validators in block verification.

Staking in Ethereum 2.0: when will it appear and how much can you earn on it?
Why coin staking will be added in Ethereum 2.0A brief educational program for those who do not follow the update of the project of Vitalik Buterin. Ethereum has long been in need of updating, and the main problem of the network is scalability: the blockchain is overloaded, transactions are slowing down, and the cost of “gas” (transaction fees) is growing. If you do not update the consensus algorithm, then the network will someday cease to be operational. To avoid this, developers have been working for several years on moving the network from the PoW algorithm to state 2.0, running on PoS. This should make the network more scalable, faster and cheaper. In December last year, the first upgrade phase, Istanbul, was implemented in the network, and in April of this year, the Topaz test network with the possibility of staking was launched - the first users already earned 1%. In the PoS algorithm that Ethereum switches to, there is no mining, and validation occurs due to the delegation of user network coins to the masternodes. For the duration of the delegation, these coins are frozen, and for providing their funds for block validation, users receive a portion of the reward. This is staking - such a crypto-analogue of a bank deposit. There are several types of staking: with income from dividends or masternodes, but not the device’s power, as in PoW algorithms, but the number of miner coins is important in all of them. The more coins, the higher the income. For crypto investors, staking is an opportunity to receive passive income from blocked coins. It is assumed that the launch of staking:
The first payments to stakeholders will be one to two years after the launch of the updateThe minimum validator steak will be 32 ETN (≈$6092 for today). This is the minimum number of coins that an ETH holder must freeze in order to qualify for payments. Another prerequisite is not to disconnect your wallet from the network. If the user disconnects and goes into automatic mode, he loses his daily income. If at some point the steak drops below 16 ETH, the user will be deprived of the right to be a validator. The Ethereum network has to go through many more important stages before coin holders can make money on its storage. Collin Myers, the leader of the product strategy at the startup of the Ethereum developer ConsenSys, said that the genesis block of the new network will not be mined until the total amount of frozen funds reaches 524,000 ETN ($99.76 million at the time of publication). So many coins should be kept by 16,375 validators with a minimum deposit of 32 ETN. Until this moment, none of them will receive a percentage profit. Myers noted that this event is not tied to a clear time and depends on the activity of the community. All validators will have to freeze a rather significant amount for an indefinite period in the new network without confidence in the growth of the coin rate. It’s hard to say how many people there are. The developers believe that it will take 12−18 or even 24 months. According to the latest ConsenSys Codefi report, more than 65% of the 300 ETH owners surveyed plan to use the staking opportunity. This sample, of course, is not representative, but it can be assumed that most major coin holders will still be willing to take a chance.
How much can you earn on Ethereum stakingDevelopers have been arguing for a long time about what profitability should be among the validators of the Ethereum 2.0 network. The economic model of the network maintains an inflation rate below 1% and dynamically adjusts the reward scale for validators. The difficulty is not to overpay, but not to pay too little. Profitability will be variable, as it depends on the number and size of steaks, as well as other parameters. The fewer frozen coins and validators, the higher the yield, and vice versa. This is an easy way to motivate users to freeze ETN. According to the October calculations of Collin Myers, after the launch of Ethereum 2.0, validators will be able to receive from 4.6% to 10.3% per annum as a reward for their steak. At the summit, he clarified that the first time after the launch of the Genesis block, it can even reach 20.3%. But as the number of steaks grows, profitability will decline. So, with five million steaks, it drops to about 6.6%. The above numbers are not net returns. They do not include equipment and electricity costs. According to Myers, after the Genesis block, the costs of maintaining the validator node will be about 4.75% of the remuneration. They will continue to increase as the number of blocked coins increases, and with a five millionth steak, they will grow to about 14.7%. Myers emphasized that profitability will be higher for those who will work on their own equipment, rather than relying on cloud services. The latter, according to his calculations, at current prices can bring a loss of up to minus 15% per year. This, he believes, promotes true decentralization. At the end of April, Vitalik Buterin said that validators will be able to earn 5% per annum with a minimum stake of 32 ETH - 1.6 ETH per year, or $ 304 at the time of publication. However, given the cost of freezing funds, the real return will be at 0.8%.
How to calculate profitability from ETN stakingThe easiest way to calculate the estimated return for Ethereum staking is to use a special calculator. For example, from the online services EthereumPrice or Stakingrewards. The service takes into account the latest indicators of network profitability, as well as additional characteristics: the time of operation of a node in the network, the price of a coin, the share of blocked ETNs and so on. Depending on these values, the profit of the validator can vary greatly. For example, you block 32 ETNs at today's coin price - $190, 1% of the coins are blocked, and the node works 99% of the time. According to the EthereumPrice calculator, in this case your yield will be 14.25% per annum, or 4.56 ETH.
Validator earnings from the example above for 10 years according to EthereumPrice.
If to change the data, you have the same steak, but the proportion of blocked coins is 10%. Now your annual yield is only 4.51%, or 1.44 ETH.
Validator earnings from the second example over 10 years according to EthereumPrice.
It is important that this is profitability excluding expenses. Real returns will be significantly lower and in the second case may be negative. In addition, you must consider the fluctuation of the course. Even with a yield of 14% per annum in ETN, dollar-denominated returns may be negative in a bear market.
When will the transition to Ethereum 2.0 startBen Edgington from Teku, the operator of Ethereum 2.0, at the last summit said that the transition to PoS could be launched in July this year. These deadlines, if there are no new delays, were also mentioned by experts of the BitMEX crypto exchange in their recent report on the transition of the Ethereum ecosystem to stage 2.0. However, on May 12, Vitalik Buterin denied the possibility of launching Ethereum 2.0 in July. The network is not yet ready and is unlikely to be launched before the end of the year. July 30 marks the 5th anniversary of the launch of Ethereum. Unfortunately, it seems that it will not be possible to start the update for the anniversary again. Full deployment of updates will consist of several stages. Phase 0. Beacon chain. The "zero" phase, which can be launched in July this year. In fact, it will only be a network test and PoS testing without economic activity, but it will use new ETN coins and the possibility of staking will appear. The "zero" phase will test the first layer of Ethereum 2.0 architecture - Lighthouse. This is the Ethereum 2.0 client in Rust, developed back in 2018. Phase 1. Sharding - rejection of full nodes in favor of load balancing between all network nodes (shards). This should increase network bandwidth and solve the scalability problem. This is the first full phase of Ethereum 2.0. It will initially be deployed with 64 shards. It is because of sharding that the transition of a network to a new state is so complicated - existing smart contracts cannot be transferred to a new network. Therefore, at first, perhaps several years, both networks will exist simultaneously. Phase 2. State execution. In this phase, various applications will work, and it will be possible to conclude smart contracts. This is a full-fledged working Ethereum 2.0 network. After the second phase, two networks will work in parallel - Ethereum and Ethereum 2.0. Coin holders will be able to transfer ETN from the first to the second without the ability to transfer them back. To stimulate network support, coin emissions in both networks will increase until they merge. Read more about the phases of transition to state 2.0 in the aforementioned BitMEX report.
How the upgrade to Ethereum 2.0 will affect the staking market and coin priceThe transition of the second largest coin to PoS will dramatically increase the stake in the market. The deposit in 32 ETH is too large for most users. Therefore, we should expect an increase in offers for staking from the exchanges. So, the launch of such a service in November was announced by the largest Swiss crypto exchange Bitcoin Suisse. She will not have a minimum deposit, and the commission will be 15%. According to October estimates by Binance Research analysts, the transition of Ethereum to stage 2.0 can double the price of a coin and the stake of staking in the market, and it will also make ETH the most popular currency on the PoS algorithm. Adam Cochran, partner at MetaCartel Ventures DAO and developer of DuckDuckGo, argued in his blog that Ethereum's transition to state 2.0 would be the “biggest event” of the cryptocurrency market. He believes that a 3–5% return will attract the capital of large investors, and fear of lost profit (FOMO) among retail investors will push them to actively buy coins. The planned coin burning mechanism for each transaction will reduce the potential oversupply. However, BitMEX experts in the report mentioned above believe that updating the network will not be as important an event as it seems to many, and will not have a significant impact on the coin rate and the staking market. Initially, this will be more likely to test the PoS system, rather than a full-fledged network. There will be no economic activity and smart contracts, and interest for a steak will not be paid immediately. Therefore, most of the economic activity will continue to be concluded in the original Ethereum network, which will work in parallel with the new one. Analysts of the exchange emphasized that due to the addition of staking, the first time (short, in their opinion) a large number of ETNs will be blocked on the network. Most likely, this will limit the supply of coins and lead to higher prices. However, this can also release some of the ETNs blocked in smart contracts, and then the price will not rise. Moreover, the authors of the document are not sure that the demand for coins will be long-term and stable. For this to happen, PoS and sharding must prove that they work stably and provide the benefits for which the update was started. But, if this happens, the network is waiting for a wave of coins from the developers of smart contracts and DeFi protocols. In any case, quick changes should not be expected. A full transition to Ethereum 2.0 will take years and won’t be smooth - network failures are inevitable. We also believe that we should not rely on Ethereum staking as another panacea for all the problems of the coin and the market. Most likely, the transition of the network to PoS will not have a significant impact on the staking market, but may positively affect the price of the coin. However, relying on the ETN rally in anticipation of this is too optimistic.
