Cosmos has historically been an ecosystem that has promoted horizontal scalability, as opposed to vertical scalability. The Cosmos ecosystem has been able to scale horizontally more efficiently than any other ecosystem as a result of having the most mature interoperability protocol and software development kit in cryptocurrency, known as the Inter-Blockchain Communication Protocol (IBC) and Cosmos Software Development Kit (Cosmos SDK). Simply put, IBC is a set of standards that facilitates communication between blockchains in the Cosmos and the Cosmos SDK is an open-source framework for building permissionless Proof-of-Stake (PoS) blockchains. IBC and Cosmos SDK enable teams to spin-up application-specific PoS blockchains with ease, which connects to all other PoS blockchains built with Cosmos SDK and IBC. As of time of writing, there are 46 zones (Cosmos SDK blockchains) that are connected to IBC. The power of having the flexibility and optionality to create your own blockchain in the Cosmos allows the ecosystem to scale ‘horizontally’. Any time blockspace reaches capacity on a single blockchain, another blockchain can be conceived that connects to the existing blockchain. This is in stark contrast to other ecosystems such as Ethereum, whereby an application suffers if blockspace on Ethereum is at capacity because bandwidth becomes much more expensive. Now, for the first time in Cosmos history, there are multiple vertical scaling solutions being built in the Cosmos ecosystem that complement existing horizontal scaling solutions that already exist within the ecosystem. This article focuses on four vertical scaling solutions being worked on in the Cosmos, which include (Cosmos Hub) Interchain Security, Dymension, Celestia and Saga. The Cosmos ecosystem is unique in that each vertical scaling solution being worked on intrinsically scales horizontally as well, thanks to the flexibility facilitated by the modularisation of Cosmos.
When bandwidth becomes expensive on networks such as Ethereum, users suffer from high transaction fees. Networks such as Ethereum have attempted to solve issues with scalability by creating scaling solutions that work ‘vertically’, as opposed to ‘horizontally’. Vertical scaling entails another layer being built on top of Ethereum network, which leverages the underlying security of Ethereum (known as the Layer 1) yet handles transaction execution off-chain (known as the Layer 2). This is an important step to take transaction execution off-chain because as of right now, transaction execution on Ethereum is responsible for the majority of bandwidth woes. Another word for a Layer 2 is an execution layer because transactions are executed off-chain. After transactions are executed on a Layer 2 (execution) layer, a proof is sent to the underlying Layer 1 (e.g. Ethereum) of the state changes that have occurred off-chain. There is then either a period of time whereby other actors in the network can prove fraud if execution off-chain is different to what has been written on-chain (via fraud proofs) or a verifying contract on-chain has to verify the validity of a zero-knowledge proof coming from an actor such as a sequencer that must also ensure all transactions are available so any full node can recover all transactions in order to also verify that execution being written on-chain is correct. Without diving too deep into the technical details, simply speaking Layer 2s can save users gas due to superior encoding, which is well-explained by Vitalik Buterin here.
Using a Layer 2, or vertical scaling is an alternative way for users and applications to execute transactions off-chain and write data to the Layer 1 to save blockspace by using compressed data and calldata (as opposed to writing directly to storage of a Layer 1, which is more expensive bytes-wise) and hence results in lower transaction fees.
In the past, Cosmos and Ethereum have taken a completely different approach, with Ethereum focusing on vertical scaling and Cosmos focusing on horizontal scaling. Now, the two ecosystems seem to be converging as both are making progress towards incorporating elements of the opposite approach to scaling in order to compliment its existing work on either vertical or horizontal scaling. This article will focus on vertical scaling solutions that are in the works in the Cosmos ecosystem that aim to complement the existing horizontal scaling solutions that are already available in the Cosmos. In particular, this article will cover 4 vertical scaling solutions in no particular order that are being worked on in the Cosmos, including: Interchain Security, Dymension, Celestia and Saga.
The first vertical scaling solution to mention going live in the Cosmos is Interchain Security on Cosmos Hub. In short, Interchain Security allows networks to lease security from the Cosmos Hub. In practice, this means that networks do not have to spend time ‘bootstrapping’ validators for its network, which can be a drawback of horizontal scaling. To explain further, each network that goes live in the Cosmos has security equal to the amount of value it has staked, meaning there is an argument that networks could be seemingly less secure in the Cosmos if the amount of assets backing a network (staked) is not high enough. For example, due to the nature of Tendermint consensus, if a validator (or group of validators) controls more than 34% of stake on a network, it is able to halt finality in a Cosmos network and essentially censor a network. Therefore, it can be appealing for a Cosmos team to instead opt for using the security of Cosmos Hub, which currently has ~$1.5bn worth of stake (ATOM) securing it. Not only would a team not have to worry about increasing the value of its network to ensure the security of it but it can also ‘lease’ validators that already exist on Cosmos Hub and therefore not have to do business development work to obtain validators and work on its security budget for its own validator set. In return, a ‘consumer chain’ (a chain that borrows security from Cosmos Hub) pays a leasing fee to the Hub itself and those who secure it, which is x% of a consumer chain’s emissions schedule being redirected to Cosmos Hub delegators. The fee paid to Cosmos Hub delegators for each consumer chain will be specified in a Cosmos Hub governance post. A governance post that pitches a team’s vision / product is required from teams looking to rent security from Cosmos Hub because consumer chains are ‘permissioned’, meaning consumer chains can only borrow security from the Hub if enough ATOM holders vote YES on it in a governance vote. One nice feature of interchain security is that it gives team the choice of either creating their own ‘custom consumer chain’ or ‘contract consumer chain’. The main difference between the two comes down to the binary that validators run. In contract consumer chains this is standard, whilst in customer consumer chains teams have the flexibility of customising the binary to experiment with different transaction fees and transaction assembly. A good overview of Cosmos Hub interchain security versus other solutions is presented here:
Figure 1 — The advantages Interchain Security offers versus existing deployment options (source: Informal Systems)
Whilst the promise of leasing security from Cosmos Hub sounds enticing, there is a trade-off to be had here on decentralisation of Cosmos Hub. This is because validators that operate nodes on Cosmos Hub will also be required to run nodes for consumer chains simultaneously to the Hub (at least in version 1). This extra requirement on validators will likely result in validators needing ‘beefier’ hardware in order to keep up with the workload as consumer chains vertically scale whilst borrowing security from Cosmos Hub (similarly to shards borrow security from Ethereum in that ecosystem). To put it simply, validators suffer at the hands of making it easier for teams wanting to get a headstart with security and a validator set. However, it is important to note that consumer chains always have the option to create it’s own network (i.e. a team can use vertical scaling via interchain security to start and then transition to horizontal scaling outside of the Cosmos Hub with its own blockchain at a later point). To date, there is two projects that are a certainty to use interchain security, which is Quicksilver and Neutron. Quicksilver for example, has opted to use interchain security over building out its own network because it is focused on liquid staking, which directly impacts security of all Cosmos networks, therefore security of its own chain is paramount in order to keep the entire Cosmos ecosystem secure.
Another vertical scaling solution being worked on in the Cosmos is Dymension. Dymension is taking a very similar approach to Ethereum’s current vertical scaling roadmap. The main difference that Dymension is taking compared to Ethereum is the level of customisation and flexibility on offer versus what is available in Ethereum. Dymension is working on creating a Rollup Development Kit (RDK). The RDK takes inspiration from the Cosmos SDK and can be tweaked effortlessly by any team, depending on their needs. Dymension is working on ‘enshrined rollups’, which communicate and transact with the settlement layer via native protocols and modules and thus increase the overall security over traditional rollups. Another element Dymension has thanks to interoperability properties materialising from the Cosmos is that of native interoperability between Dymension rollups, which are connected to the Dymension settlement layer. Another unique property Dymension is leveraging that is not available in the Ethereum ecosystem is PoS for sybil resistance / to solve the keeper’s dilemma. Dymension has come up with a unique way to solve the keeper’s dilemma that rollups currently face in Ethereum.
Dymension is in its very early stages, so not much can be given away about the protocol design at this stage. The best way to think of Dymension is like Ethereum’s current settlement and execution layer design (e.g. ORUs executing tx off-chain and then writing state to the ‘settlement’ layer), only Dymension inherits many properties that makes Cosmos networks so dynamic, such as native interoperability, PoS and a developer framework to easily spin-up rollup chains.
Related to Dymension but also with its own unique design that is a vertical scaling solution going live in the Cosmos is Celestia. In a nutshell, Celestia is a ‘data availability network’. Breaking this down, Celestia validators guarantee that state (data) is available for verifiers to verify themselves that execution has been done properly off-chain in order to mitigate any need for a challenge period on the ‘settlement layer’. Celestia network itself does not execute any transactions. It is merely a network that has the latest state of an L2 that can be leveraged by verifiers to determine whether or not data is available (and therefore can reconstruct the previous state to check if execution has been done appropriately in different intermediate states). A nice design choice of Celestia is the way in which it uses 2d Reed-Solomon erasure coding to involve non-consensus nodes in determining whether or not data is indeed available. This is a scaling decision in itself, as light nodes in the past had no role in consensus. In Celestia, light nodes can probabilistically determine that all transactions are available because a block producer would have to withhold >50% of a block’s data in order for censorship to occur. Due to the technology of 2d reed-solomon erasure coding, it becomes a trivial task for light nodes to find out whether even just 1 transaction (which could be 1 in potentially thousands) is being censored by a block producer sequencing to a settlement layer. In data availability design without this, it is burdensome for light clients to sample transactions because if only 1 transaction was withheld (which could be critical), the more transactions that were being batched to a settlement layer, the harder it would be for a light client to find, the less security a roll-up would have.
In the Ethereum ecosystem, a rollup (such as Optimistic Rollup) could post calldata to Ethereum but it is still (relatively) expensive versus posting the same data to Celestia to ensure data is available (and therefore recoverable to challenge what is sequenced to the settlement layer). There is a chance that rollups that exist in Ethereum now might only use Ethereum in the future to challenge the off-chain execution if it was incorrect (and slash on Ethereum) and use Celestia as the data availability layer to verify that data is available in order to submit the challenge.
Celestia is also working on creating a framework that allows zones (outside of rollups) to also write transaction data to Celestia, whereby Celestia ensures it is available. In Celestia’s own words:
Optimint is the software that allows a chain to deploy directly on Celestia, as a rollup. It spins up its own p2p network, collects transactions into blocks and posts them onto Celestia for consensus and data availability.
Optimint is essentially a framework for developers to use that does not require them to undergo business development to find their own validators or create its own security budget as Celestia handles the work for them. Optimint is the consensus layer of Celestia, which provides a framework for transaction ordering that can be used in the data availability layer as well as settlement layer (if required). It is likely that Optimint could rival interchain security because the value proposition is the same for both of them. It is unknown how consensus will differ in Optimint vs Tendermint as it exists in Cosmos Hub today.
In any case, Celestia is a completely unique and elegant design that tailors to all execution layers’ needs. Celestia is blockchain-agnostic and provides consensus over data availability within an execution layer. This is a powerful concept and Celestia’s importance could transpire across both Cosmos and Ethereum in the near future.
Finally, another vertical scaling solution being built in the Cosmos is Saga. Saga is a network that is purpose-built to give each application that launches on its network its own execution environment. This means there could potentially be hundreds / thousands of ‘chainlets’ running on Saga. A core value proposition of Saga is that execution environments are customisable, an application has the flexibility to choose its own execution environment depending on its needs. The power of each individual application having its own execution environment is that resources can be managed in a more efficient way. Whenever one application runs out of blockspace, it can easily spin-up another execution environment that is focused on a particular subset of the activity from the original application via deploying another instance of the same smart contract in order to handle the load. Saga suffers a relatively similar fate to interchain security in that there is a lot of burden placed on validators in order to allow applications and application-specific chains to run smoothly. It is Saga’s intention to have chainlets provisioned by validators in a fully-automated way but this is a complex challenge to solve. If Saga is able to solve provisioning automation in an efficient way, it will be a force to be reckoned with within the Cosmos.

To conclude, traditionally Cosmos was fully-focused on scaling the ecosystem horizontally. Horizontal scaling is in stark contrast to the approach Ethereum has taken, which has focused on scaling the network vertically. In 2022, there has been a trend for teams to start working on experimenting with vertical scaling solutions in the Cosmos to complement the already existing horizontal scaling solutions that exist. The four major vertical scaling solutions that are being worked on in the Cosmos are Cosmos Hub Interchain Security, Dymension, Celestia and Saga.
Each vertical scaling solution comes with its own design choices and trade-offs. However one theme holds true amongst all vertical solutions being worked on in the Cosmos — flexibility. All vertical scaling solutions in the Cosmos are completely customisable and offer a tremendous amount of freedom for developers to experiment with. The original value proposition of the Cosmos — IBC, Cosmos SDK and Tendermint is being leveraged in different ways by new vertical solutions in the Cosmos. What is unique to scaling in the Cosmos is that it is intrinsically horizontal. All vertical scaling solutions being built still scale horizontally. This is in large part due to the seamless experience, standards and software development kits that are prevalent in the Cosmos. Even if a vertical scaling solution is built that leverages the security of an underlying validator set, it scales horizontally in an easier manner than what can be found in other networks because of the modularity of the Cosmos. For the first time in Cosmos history, vertical scaling will accompany existing horizontal scaling to pioneer what could be the most scalable blockchain ecosystem in existence.

Centrifuge is building the operating system to connect the global financial supply chain.
Centrifuge is bridging real-world trade finance assets like company invoices into the world of decentralized finance through the Tinlake asset-backed lending protocol. Through Tinlake, users can tokenize non-liquid assets such as invoices (e.g. ConsolFreight) or streaming royalties (e.g. Paperchain) and borrow against these securitized assets.The Centrifuge Chain, which hosts the Tinlake protocol, is a Substrate-based Proof-of-Stake chain secured by a small set of validators including Chorus One. By delegating Centrifuge (CFG) tokens, stakers help maintain the network and its bridge to Ethereum, for which they earn staking rewards.

For any organization dealing majorly in crypto, the last few weeks were something akin to a bad dream. Over $1T of market cap was washed out in the last 3 months with many believing that we’re already in a bear market. Queries about the bear market, recession, and other related terms have gone up on Google by more than 100% compared to the previous few months. The global equity markets shadowed this behavior too with the macro headwinds of high inflation & slower growth finally starting to haunt the central banks.
It’s safe to say that the traders were the worst hit by this sudden price movement with more than $1B worth of liquidations taking place between June 13 and 14 alone. The cascading effects of over-leveraged trades were visible in full display. But as they say — when in doubt, zoom out. Anyone worth their salt would agree that blockchain is a revolutionary technology and cryptocurrencies will change the way people transact and trade in the next decade. And we, at Chorus One, are not the only ones to believe so.
Goldman Sachs recently released the eleventh edition of its annual insurance survey where cryptocurrency was included for the first time. This survey considers inputs from 328 Chief Investment Officers and Chief Financial Officers, representing companies that have nearly $13 trillion in balance sheet assets. Nearly 6% of respondents said they were invested in crypto or are considering doing so. Even Bank of America released a report recently where more than 90% of the people surveyed said that they plan to invest in cryptocurrencies in the next 6 months. It’s no secret that more and more institutions are increasing their exposure to digital assets and with the recent twists and turns in the Celsius saga and rumours of them “managing their money like degens” or “having complete naked exposure to the market”, institutions deserve a safer and less-riskier option to invest where they, and only they, can control their funds. And that’s where staking comes in.
Staking refers to the “locking up” of your digital assets and earning the right to validate the next block of transactions. This is possible for most of the tokens that are based on the Proof-of-Stake consensus mechanism like Solana, Avalanche, Cosmos, Tezos or Ethereum (expected to be PoS driven by 2022). And Proof-of-Stake consumes only a fraction of energy compared to the energy-guzzling Proof-of-Work. And of course, you get rewarded too. According to Staking Rewards, the average interest rate currently is greater than 9% but it can swing between single-digit and triple-digit APYs depending on your asset. In fact, if you currently own Proof-of-Stake-based tokens and don’t stake them, you’re not only losing rewards but your portion of assets would also be continuously shrinking in relation to total supply as the rewards for most of the tokens are mainly generated through inflationary returns.
Enterprise staking is one the safest options for institutions that take a long-term view of the crypto ecosystem as it is not market-dependent. Investing in a liquidity pool comes with its own set of risks not limited to impermanent losses, volatility, no fixed returns, hacks etc. But when you have your tokens staked, even though the market value of your assets might drop, they continue to accrue predictable rewards in that same asset.
Staking is also custody-friendly as you continue to hold control of your institutional assets. No other party can seize control or deny you your accrued rewards, not even a staking company like Chorus One. Compliance is usually one of the top concerns for institutions and hence we also have partnerships with global custodians like Finoa. We also work with custodians of your choice when you partner with us.
Of course, you can run your own validator nodes too but it’s an extremely complicated process requiring expertise and hands-on knowledge and that’s where companies like Chorus One come into play. We’re one of the biggest staking companies globally and work with some of the biggest cryptocurrency exchanges, VC funds, family trusts and other organizations. We monitor our nodes 24/7 and have stringent SLAs with all our institutional clients that act as guarantees against any risk of slashing. In fact, we have never been slashed. Since 2018. We work with the best minds in crypto so you can spend your time deploying funds and not worry about validator technicalities.

The bull cycle of 2021/2022 was largely defined by decentralized application platforms that provide an alternative to Ethereum experiencing adoption and growth within their ecosystems. All these platforms have one thing in common: they need operators commonly called validators actually running the underlying infrastructure to enable the applications built on them to be usable.
Most importantly, there should be enough independent operators for such a network to be considered sufficiently (politically) decentralized, to avoid a subset of parties being able to shut down applications, censor transactions, or in other ways impede the credible neutrality of the platform.
A core belief within Chorus One is that the increasing adoption of decentralized applications will lead to further networks springing up; a directional trend that can be observed looking at the growth of application-specific chains, e.g. in Cosmos, the pioneering and leading ecosystem of this approach (via the Cosmos SDK and IBC), which is also being pursued by similar initiatives in other ecosystems (e.g. Avalanche subnets, Polygon supernets, Substrate chains on Polkadot). Notably, in recent months, some of the most used applications including decentralized derivatives trading platform dYdX confirmed and NFT juggernaut Yuga Labs hinted at plans to launch their own application-specific blockchain.
Given these forces on the network supply side, the demand and competition for professional operators are growing and protocol designers need to think about how to incentivize validators to join their ecosystems — as opposed to a “build it and they will come” mentality.
The following post aims to provide an insight into existing strategies and criteria for network foundations to foster decentralization and create a healthy validator set via stake delegation programs.
As mentioned, a key tool in the toolbox of network foundations, who generally are endowed with a decent portion of the underlying protocol’s staking token and the mandate to grow the ecosystem, is the ability to distribute the stake to independent validators. Crucially, here we are not talking about giving tokens directly to validators through e.g. validator-specific investment rounds or incentivized testnets, which are other viable strategies to create alignment. Rather, we talk about delegating foundation tokens to validators based on some sort of evaluation. This mechanism can be used to continuously reward operators that add value enabling them to build a stake in the network via commission rewards. This cannot be underestimated as both a bootstrapping mechanism for validators to join your network and as a mechanism to reward valuable contributions, as well as continued participation and performance.
In the following table, we aim to highlight some of the different criteria choices providing examples of existing foundation delegation strategies that can be taken into consideration. We also look at two exemplary liquid staking protocols, another interesting party with similar goals to a protocol foundation that has been innovating on establishing methods of how stake is distributed among their validator sets.
Furthermore, most programs also institute a maximum fee that validators are allowed to charge. Notably, it can be observed that some liquid staking protocols actively try to minimize validator fees as their main product is the APY of their liquid staking token.
Finally, it is also interesting to note which programs are carried out in an automated fashion on-chain, which is spearheaded e.g. by Solana stake pools and Polkadot’s 1,000 validator program (see links below).
Once aligned on the desired criteria, you’ll need to decide on the frequency and how to communicate the criteria, how people can take part, and how decisions will be communicated. We recommend using a mailing list for upgrade communication and Discord or Telegram for active discussion. We have collected some critical resources from other delegation programs at the end of this post for inspiration.
An alternative to delegation programs that some networks opt for is to run foundation nodes themselves, a practice that we would largely discourage or at least try to limit for early phases of the network in which some additional control of the foundation might be necessary or in some minor fashion to ensure the network’s validator software and surrounding process are useable. At scale, this practice takes away the chance for validators to truly become a part of the network and will ultimately result in a centralized, and thus pointless, network.
Well-designed stake delegation strategies are a powerful bootstrapping mechanism to get independent operators interested in your decentralized network. In addition, they can serve as a mechanism to continuously reward valuable contributions such as community engagement and open-source tooling.
In this post, we touched upon why delegation programs are needed, the underlying goals, and what criteria can be used to conduct them. There is a lot of work to be done evaluating the effectiveness and improving and innovating on delegation strategies we have introduced here.
