Hedging LP positions by staking
We explore challenges for Liquidity Providers (LPs) in DeFi, discussing the impact of real-time market price discrepancies and proposing MEV-optimized staking for mitigating these issues.

Decentralized Finance (DeFi) is a profound paradigm shift, redefining how the world engages with financial services. At its center, open liquidity provisioning allows for seamless decentralized trading,lending, and more complex financial strategies. In contrast to traditional finance, centralized intermediaries are not required as liquidity providers, instead, users are empowered to bootstrap liquidity.

Automated Market Makers (AMMs) - see e.g. Uniswap - allow anyone to contribute assets to pools and thus facilitate trading. Users are compensated with a share of trading fees, and potentially,idiosyncratic incentives added by parties benefiting from liquidity (e.g. a project issuing a token). AMMs are simple - users may provide liquidity over the entire price range, or for a specific pricing interval.

DeFi composability and the absence of asset custody by intermediaries push market participants to opt for AMMs over centralized exchanges (CEXs). AMMs have the potential to outperform centralized exchanges in terms of liquidity provision (G. Liao and D. Robinson).

Conversely, Decentralized Exchanges (DEXs) driven by a Central Limit Order Book (CLOB) - see e.g. dYdX v4 - demand a substantial pool of assets and ample order book depth for smooth operation. A CLOB is adept at consolidating liquidity around the market price and has the flexibility to adjust quotes as needed.

However, the process of actively matching buy and sell orders to connect traders is complex and rewards sophistication. Market makers in CLOB-based DEXs must consistently update their positions to prevent their orders from becoming stagnant. This dynamic nature of CLOBs, while offering powerful tools for price discovery, also renders liquidity provision a more intricate endeavor. This complexity is particularly pronounced for those traders who may not have access to real-time market data, as remaining profitable in such an environment requires a deep understanding of market dynamics and order flow.

AMMs and decentralized CLOBs are the dynamic engines driving the DeFi ecosystem. For Liquidity Providers (LPs) navigating the DeFi landscape, a central challenge looms – adverse selection, as extensively explored in J. Milionis et al for AMMs and U. Natale et al for CLOBs. This article delves deep into these mechanisms, highlighting challenges and opportunities facing LPs. We’ll zoom in on Uniswap v3, the most widely used AMM, to explore the complexities and potential solutions in this dynamic landscape. In the final section, we argue that staking, specifically with a validator optimizing for MEV, is a way of recouping potential losses.

LPs profitability and adverse selection

Uniswap is the leading DEX by volume with $1.5 trillion in lifetime volume since its 2018 debut (cfr. DefiLlama), and over $1 trillion alone processed by Uniswap v3 (H. Adams et al). Central to its operation is the concept of concentrated liquidity (CL), empowering LPs to offer assets within specific price ranges. LPs facilitate the smooth flow of assets and liquidity, making the success of these AMMs critically dependent on LPs participation, who provide liquidity in exchange for trading fees.

For LPs participating in AMMs, the primary challenge is adverse selection, cfr. J. Milionis et al. This issue arises because parties with access to real-time market prices can exploit price discrepancies between AMMs and other platforms. These transactions often involve arbitrage between CEXs and DEXs. To succeed in capitalizing on price disparities, individuals need not only priority access to the first few on-chain transactions in a block (T. Gupta et al) but also the ability to execute high-quality trades on CEX. This transaction flow between different venues forms the backbone of efficient AMM trading, however, it can have adverse effects on LPs via adverse selection.

In U. Natale et al, we evaluate how pricing on dYdX v4 could be impacted by the presence of another CLOB with higher liquidity, for a given asset - e.g. on a CEX. However, it's important to note that this platform is not live at the moment. This means that making an exact comparison of the profitability of professional Market Makers in a decentralized order book like dYdX v4 is currently unfeasible. Consequently, for the remainder of our analysis, our primary focus will be on Uniswap v3, where Concentrated Liquidity presents opportunities and challenges worth exploring.

LPs’ PNL Estimator

Estimating the effective profit & loss (PNL) for a LP has been a subject of extensive study in literature. One widely debated estimator, frequently discussed in the context of the profitability of ETH/USDC LPs on Uniswap v3, revolves around markouts, as outlined in a series of medium articles by Ambient finance, formerly known as CrocSwap. However, it's crucial to highlight that markouts, as an estimator, may not present a holistic view of LP profitability on Uniswap v3.

This is because markouts typically overlook the genuine liquidity and the precise price range within the pool. Consequently, they may overlook changes in the value of the numéraire within the pool, focusing solely on the risky asset's fluctuations. The omission of these critical factors can significantly impact the accuracy of LP profitability assessments.

In order to avoid possible biases in the analysis, we decided to use an estimator that is dependent on the actual variation in pool value, see here for the description of the mathematical framework.

Uniswap v3 PNL Estimate

To estimate the PNL, we built a Dune Analytics dashboard, where we consider the USDC/ETH pool with 0.05% fees.

The picture above shows the final Pool’s PNL since the beginning of the year, which corresponds to a general gain of around $35M. Let’s observe that, to achieve this figure, we need to consider the total TVL as capital deployed for the strategy. At current TVL of $206.59M, this corresponds to a 16.9% gain, instead, by considering the maximum historical TVL (~$320M) the total gain since the beginning of the year is around 10% of the capital deployed.

If we focus on the PNL from pool value variation, i.e. no fees, we can see how the overall gain is primarily driven by accrued fees. Indeed, the adversarial selection produced - at time of writing - a loss of $400k, with a maximum loss of ~$1M in May.

If we compare with the ETH price movement during the same time period, we can see that this effect is primarily driven by the movement in ETH price.

More precisely, this is an effect related to price volatility, as shown in Milionis et al. Indeed, when price volatility sharply increases, the price discrepancy between Uniswap v3 and other venues also increases, amplifying the MEV size. The two plots below show the pool value variation due to Toxic Flow and the correlation between pool value from toxic flow and spikes in volatility (24h Moving Average). Here by Toxic Flow we indicate all the transactions coming from informed traders that generate a negative PNL for the LPs. Given the nature of DEXs, informed traders aim to include their transactions in the top part of the block (we used the first 10 txs in the block) to avoid price movements due to market activity.

Before concluding this section, it's worth mentioning that, despite the PNL of $35M due to the accrued fees, being competitive and effectively implementing a strategy that generates a positive PNL is a complex undertaking. This is because there are sophisticated LPs, and the accrued fees need to be divided among all participants. Barriers to entry include access to highly performant price feeds and pricing models, as well as optimized execution. Furthermore, the previous estimator considers the PNL from the pool value, inherently assuming that the entity deploying the strategy has infinite capital that can be allocated each time the price moves. If we utilize the estimator defined in Eq. (8) of this document, we can illustrate how an LP with a fixed initial amount deployed in the liquidity provision strategy experiences a PNL of -30% (without accounting for the fees), as demonstrated below.

Additionally, by updating the positions every minute, the LP accumulates a total gas cost of $2M since the beginning of the year. It's important to note that this cost can be hedged with solutions like Alkymia, in which Chorus One has invested.

Re-Capture MEV by staking

We have seen how LPs, who diligently provide liquidity, may face losses as arbitrageurs exploit price differences between centralized and decentralized platforms. Staking represents a strategic approach for LPs to recapture a portion of the extracted MEV. This is particularly advantageous when LPs choose validators that are actively working to optimize MEV yields, like Chorus One (see previous chapter). By aligning their staked assets with validators who specialize in maximizing MEV yields, LPs can amplify their returns while bolstering their resilience against the challenges of adverse selection.

This endeavor is not about exploiting MEV at the expense of the ecosystem but rather about recapturing it for the benefit of those who contribute to the DeFi landscape. Maximizing MEV yields is a way to ensure that the value generated from the MEV ultimately flows back to the stakers, aligning incentives and fostering a fairer and more rewarding DeFi ecosystem. Moreover, the staked amount can be thoughtfully hedged against price fluctuations using external sources, creating a comprehensive strategy to safeguard LPs' investments and enhance their gains.

In summary, LPs, who play a pivotal role in DeFi liquidity provision, can employ a multifaceted strategy combining liquidity provision, staking, and hedging to mitigate the impacts of adverse selection and recapture a portion of the extracted MEV. By making strategic choices in validator selection and actively managing their positions, LPs can navigate the complexities of the DeFi landscape and emerge as resilient and profitable participants.

Ecosystem Review: NEAR
We examine NEAR's technical framework, cross-chain composability, significant on-chain activity spurred by the recently launched KaiKai shopping app, and the transition towards a Blockchain Operating System (BOS) that seeks to transform Web3 accessibility.
November 7, 2023

  • This is an excerpt from the Quarterly Insights Q3 2023 report. Find the full report, here.

This edition of the Ecosystem Review covers NEAR, which in technical terms, is a layer one, sharded, proof-of-stake blockchain, and in practical terms, targets to become the operating system (“OS”) for an open web.

Each transaction in the NEAR blockchain costs less then $0.01 and blocks are finalized in only 2 seconds, placing the protocol in the group of fast and cheap blockchains. The decision to dive deeper into Near this quarter is based on the attention it’s getting from the announcement of Blockchain Operating System and other apparently successful initiatives for expansion of the ecosystem, which have been reflecting in increased on-chain activity (Fig 1), despite the current market scenario.

Before revealing the main actor behind the spike in network activity, this article will review the protocol’s technical architecture, the staking and economics parameters and other relevant aspects, like cross-chain composability.

For the new and old fans of NEAR, the community is meeting up in person in the upcoming NEARCON, a 4-day event to take place in Lisbon in November.

The NEAR protocol is a proof-of-stake network which means that Sybil resistance is done by staking the native token, also called NEAR or Ⓝ. The time is measured in epochs. An epoch is made of 43,200 blocks. Ideally an epoch lasts about 12 hours, but in practice it lasts longer than that, since average block time is currently around 1.11 seconds according to nearblocks.io - the official block explorer.

NEAR is a layer one blockchain. Because of its sharded architecture, a block in NEAR includes one chunk for each shard, and the chunks respectively  include the transactions executed for its associated shard. In terms of network participants, the block producer is a heavy duty, since it requires participants to store the full ledger (aka full node) for all chunks. In order to scale and decentralize the set of operators, the protocol is designed to allow a lighter type of node in addition to the block proposer, called chunk-only producer, who creates blocks for single chunks.

NEAR features a runtime layer to execute code, and supports the deployment of applications, a.k.a smart contracts. Smart contracts are written in either JavaScript or Rust, and the NEAR SDK compiles the contracts into WebAssembly (WASM). The NEAR runtime uses the concept of Gas to unify the cost of execution and bandwidth. Each WASM instruction or pre-compiled function gets assigned a gas fee  based on measurements on a common-denominator computer. Same goes for weighting the used bandwidth based on general unified costs.

Gas is priced dynamically for each block, and adjusted based on the consumption of the limit in the previous block. When a smart contract wants to store some data, storage cost is computed, and the appropriate amount of NEAR tokens is “locked” on the account. When data is removed, tokens are unlocked. Unlike gas, these tokens are locked in the smart contract’s account, so the user doesn’t directly pay for it. 30% of gas fees users spend on a particular application will go to the contract’s account, generating revenue for the deployer via usage.An interesting aspect of the NEAR protocol lies in the accounts system: it natively supports account abstraction, which means that instead of identifying users by their public/private key pairs, it defines accounts as first-class entities. The implications in usability, are:

  • users can use readable account names, ex: `chorusone.near`
  • multiple key pairs with different permissions can be associated to a single account
  • hierarchical accounts structure used to manage multiple smart contracts under one parent account - since each account holds only one smart contract
  • accounts/public keys are created using transactions, they are stored and can be found querying the ledger.

A complete overview of the technicalities of the Protocol can be found in https://docs.near.org.

Cross-chain Composability

As stated previously, NEAR has its own runtime, which is not compatible with the Ethereum Virtual Machine. However, using a Layer-2 like approach developers can deploy Ethereum-compatible applications to NEAR, and leverage its lower cost and higher throughput platform. It is the case of the Aurora project, an Ethereum Virtual Machine (EVM) built on top of the NEAR Protocol. The most popular tools built for EVM development are also available to be used on Aurora.Also adding to interoperability, the Rainbow Bridge plays an important role as it allows transferring assets between the Ethereum Blockchain and NEAR. The Rainbow Bridge protocol is a trustless, permissionless protocol for connecting blockchains, developed in-house, by the NEAR team.

The core idea behind it is to implement an Ethereum light client in Rust as a NEAR contract, and a NEAR light client in Solidity as an Ethereum contract. Trust assumptions are minimized using this protocol, as anyone can deploy your own instance as a smart contract. This can facilitate simple (e.g. a canonical token migration) and complex interactions between NEAR and ETH, for example, allowing ETH holders holding a given token to vote in your DAO on NEAR.

Activity

In contrast to other ecosystems, the NEAR blockchain was able to keep up a relatively high level of daily transactions over the past year, despite the dramatic slow down the whole crypto space has seen. Activity metrics have spiked at a daily 1M transactions in August 2023, leaving behind previous heights of approximately 500k daily transactions (Fig 2).

Leveraging NEAR account system, and Flipside Crypto to plot the top accounts by number of transactions shown in Fig 3, the main driver of the increased activity can be spotted: the accounts and tokens related to Kai-Ching, or $KAIC, the token of KaiKai, a Singapore-based shopping app:

Fig 3: Top accounts by number of transactions per month since January ‘23. Source: flipsidecrypto.xyz

KaiKai is an application built by Cosmose, a nine-year-old company targeting the use of artificial intelligence to improve off-line shopping with ultra precise recommendations and advertising. Cosmose was featured in the list of the 100 world’s most promising private AI companies in 2022. With a team distributed across Warsaw, Shanghai, Hong Kong, Singapore, Tokyo and Paris, the company recently raised an undisclosed amount at a $500 million valuation, up from $100 million when it closed its $15 million Series A financing in 2020. The Near Foundation has made a strategic investment in Cosmose, announced in April '23, according to techcrunch.com.

Fig 4 illustrates the relevance of KAIKAI-related transactions in the ecosystem, in contrast with overall transaction volume.

KAIKAI uses AI to curate and personalize vendors’ offers and partnerships. In contrast with the conventional e-commerce, users shop online through the app but pick it up in person. With every purchase, users are rewarded with the $KAIC as cashback that never expires. The token is also used in the app to facilitate refunds, but at this point, it can not be traded anywhere, nor exchanged for Fiat.

This year, the Foundation also launched Near Horizon, a social platform to connect everyone involved in the ecosystem: builders, contributors and backers can create a profile to share and discuss ideas, hire members to the team, apply for funding etc. This came shortly after NEAR announced its transition to a Blockchain Operating System (BOS), an initiative to establish NEAR as the entry point into the decentralized internet - the Web3. BOS is designed to effortlessly create and distribute decentralized apps on any blockchain, not only on NEAR. BOS is focused on accessibility.

You can use javascript, the most popular programming language (according to statista.com) to create, fork and reuse components already published by other users; connect with a NEAR account to retrieve owned components; and deploy and host naturally open source apps on-chain. Not only adding value to the ecosystem, BOS seems like a good progress to the onboarding of developers to Web3.

Staking and Economics

At the time of writing, the project was valued at more than $1 Billion (source: coinmarketcap.com ) and the NEAR token was traded at $1.04, not far from its launch price in October 2020 - see Fig 5. The Proof of Stake network is run by 213 nodes and secured by 604.9M of staked NEAR, equivalent to $630M, or 60% of the total token supply. Judging by the list of nodes, most of them are managed by professional infrastructure providers, and are distributed globally. The largest validator concentrates 7.8% of voting power and the super minority is formed by only the top 8 validators.

The annual inflation rate is 5% and the staking APR is 7% according to Staking Rewards. The inflation is distributed to stakers every epoch in the form of block rewards. The protocol supports staking delegation, which means that token holders can natively and securely stake their tokens with node operators they trust. During each epoch, validators’ voting power in the network remains constant. Changes to stake amounts are processed at the beginning of the next epochs, e.g. it takes a maximum of 12 hours to start participating in rewards after delegating NEAR. The unbonding period is also comparatively short: upon unstaking, users receive their tokens after 3 full epochs (36-48 hours).

A sneak-peek at validator side MEV optimization
With Ethereum staking rates having risen to currently around 23% of total supply, validator-side MEV is quickly becoming a topic of immense interest. So take a sneak peek behind the curtains in the first article of this Quarterly Insights report.
November 7, 2023
5 min read
  • This is an excerpt from the Quarterly Insights Q3 2023 report. Find the full report, here.

Staking rewards generally derive from a combination of inflationary rewards, transaction fees, and MEV. We are certain that a complete understanding of the Ethereum PBS pipeline allows validators to extract more MEV through targeted infrastructure optimizations.

While adjacent topics have been discussed in literature (e.g. Schwarz-Schilling et al., 2023), Chorus One is the first node operator to successfully test out different optimization approaches on mainnet. We find that the most impactful improvements are contingent on comprehensive internal data, and have generally not been discussed in their specificity.

The goal of this article is to share the results of a recent pilot. We will follow-up with more detail in a later, comprehensive study, which we are co-authoring with one of the most recognizable and competent teams in the MEV space.The pilot makes use of several modifications which positively impact MEV extraction. The rest of the article will discuss one straightforward, illustrative example in more detail, and present the overall results of the pilot so far.

There are two components to APR optimization. Firstly, we should maximize the payoff of the blocks we propose, and secondly, we should minimize the likelihood of missing our chance to propose (i.e. missing our slot). The first of these is more complex and can be approached in several ways, including via latency games, and other infrastructure optimizations.The latter is more accessible, and primarily hinges on running a robust infrastructure setup with appropriate redundancy. However, relay selection also plays a role. Let’s dive in!

A basic illustrative adjustment: drop underperforming relays

The goal of this section is to give an example of a straightforward MEV-adjacent infrastructure adjustment that can positively impact validator APR by minimizing the probability of a missed slot. This modification is not central to our MEV strategy in terms of impact, but it is illustrative of the Ethereum MEV supply chain.

As per conventional wisdom, a validator is best off integrating with a large number of relays, as the mev-boost auction will yield the highest bid, i.e. there is no obvious downside to soliciting a maximum number of bids.

This is only half of the story. Let’s recall how validators and relays interact in more detail. First, the validator requests a block header from a relay, which then delivers the header corresponding to the most profitable block available to the relay. In parallel, the validator also solicits bids from all other relays it is integrated with. The mev-boost auction then determines the highest bid, the validator signs the header associated with this bid, and asks all relays to deliver the payload associated with this header.

The relay that is quickest to respond (typically the relay that delivered the original bid) then broadcasts the block and returns the associated payload to the proposer. This may be done with a delay versus previous implementations (i.e. at proposer’s slot t=0), as early distribution of the payload theoretically allows an unethical proposer to build an alternative block exploiting the transactions in the block received from the relay. This vulnerability has been outlined by the “low carb crusader”, and more details can be found in this post by Flashbot’s Robert McMiller.

The upshot is that in addition to transferring bids from builders, relays also carry responsibility for propagating the final signed block to the network. This is more pronounced now than previously, as the time available for this step has been decreased. Therefore, validators should favor relays that deliver payloads rapidly, or run an idiosyncratic risk of missing their slot, for relays that underperform.In practical terms, we find that relays can diverge significantly on delivery speed, and that for one relay in particular, a routine network disturbance could lead to a missed slot if the validator depends on it to deliver a given block.

The following graph shows the cumulative probability distribution for the maximum time at which a block becomes eligible within each slot, and each line represents a relay.This is a snapshot that is relative to a subset of our nodes over a limited period, and relay performance can vary over time, i.e. should be constantly and granularly monitored. Relays are currently a costly pro-bono good, and we appreciate providers subsidizing the network in this way.

In practical terms, for this particular cluster of nodes, running the relay color-coded light blue is a negative EV decision, i.e. it should be dropped. This is due to the consistent delay it exhibits in making blocks eligible, as compared to other relays.

Our current MEV pilot: A first look at the results

Our current MEV pilot combines straightforward adjustments, like the relay selection process illustrated above, with more significant and systematic infrastructure optimizations.

The below graphs are a first look at the results, and summarize performance over approximately a quarter.

As such, getting a grip on variance requires robust statistical processing. As MEV is tail-heavy (i.e. most profit is produced by rate opportunities), results can vary significantly over time, and capital invested. We are comparing the MEV payoff distribution of the pilot with the MEV payoff realized by a set of Lido nodes. On a per-block level, we find that our pilot has improved MEV rewards significantly:

This extends to the aggregate case - over our sample, the pilot has extracted higher rewards than a “vanilla” setup with a probability approaching 100%:

The upshot is that we feel highly confident that the infrastructure optimizations implemented in our pilot study aggregate out at an APR that is consistently higher than what a non-optimized setup typically achieves.We will elaborate further on specifics in a forthcoming study.

Why is data availability important, and how is Celestia addressing this?
We explore how Celestia - the first modular blockchain network - addresses and optimizes the data availability issue.
November 6, 2023
5 min read

Celestia is the first modular blockchain network that is optimized for ordering transaction data and making it available. It solves the scalability problem of a blockchain without sacrificing decentralization and accomplishes this by separating execution from consensus and addressing data availability challenges through a technology called data availability sampling. In this article, we explore why data availability is crucial, and how Celestia addresses this. (If you're new to Celestia, we've got you covered with a quick rundown of the network in a previous article.)

Before diving into the importance of data availability, it might be helpful to have a little refresher on the basics of how most blockchains work.

Blockchains offer a range of fundamental functions that make them versatile for various applications. These functions are:

Execution: Handling transaction execution and state updates.

Consensus: Establishing agreement on transactions and their order.

Settlement: Resolving disputes and facilitating cross-chain connections.

Data Availability: Proving the publication of  transactions on the network.

Monolithic blockchains, like Ethereum or Solana, which encompass all these functions in the same chain have been the dominant model in the blockchain space. However, the widespread adoption of these systems have raised concerns about the lack of specialization and high gas fees during peak usage, as seen with Ethereum,  impacting both current and potential users. This issue underscores the need for more scalable, specialized and efficient solutions.

This is where Modular blockchains like Celestia enter.

Unlike other monolithic blockchains, Celestia decouples the data availability layer from the execution layer and focuses only on ordering transactions and their data availability,  i.e, they solely work on proving that transactions are published on the network and are available for everyone to see. The execution and settlement of transactions are left to the respective rollup. (As a permissionless network, Celestia uses Proof-of-Stake to secure its own consensus. Like any other Cosmos network, users can help secure the network by delegating their TIA to a validator like Chorus One.)

But why is data availability important?

When you make a transaction, it needs to be confirmed and added to the blockchain for everyone to see. Once the transaction is confirmed, it's put into a "mempool" where it waits for its turn to be added to the blockchain. The full nodes then download this new block, execute/compute every transaction included within this block (including yours), and make sure they are all valid. They check things like whether you have the money you're trying to send and that you're not doing anything sneaky. Full nodes therefore perform the important task of enforcing the blockchain’s rules on validators. This is where things get tricky.

Since full nodes check every transaction to verify they follow the rules of the blockchain, blockchains cannot process more transactions per second without increasing the hardware requirements of running a full node (better hardware = more powerful full nodes = full nodes can check more transactions = bigger blocks containing more transactions are allowed). But if the hardware requirements of running full nodes increased, there would be fewer full nodes and decentralization would suffer because not many people can afford to run them, and that's bad for the blockchain's security. See, the more full nodes we have, the safer the blockchain is because it would make the network more decentralized if the voting powers were well distributed. If there are only a few, we'd have to trust them a lot more, and that's risky because it's more centralized.

Now, here's where ‘data availability’ comes in. It's like making sure the information in the transactions is available for everyone to check. If the people adding new blocks to the blockchain don't share this info in the first place, it's a problem. Full nodes can't do their job of checking things, and we'd have to trust the block creators more. So, data availability is all about keeping things open and transparent to maintain trust and security in the blockchain. It's a key part of how blockchains work and stay safe.

Circling back - How does Celestia address data availability?

Celestia's primary focus on data availability (DA) enables any rollup to utilize it to solve the data availability issue, while still maintaining its independent execution environment. Due to its modular nature, any language or virtual machine can be used to build on top of Celestia.

Celestia solves the issue by using a technology called ‘data availability sampling’ - a mechanism that allows light nodes to verify data without needing to download the entire block data. Essentially, light nodes perform multiple rounds of random sampling on small portions of block data. As they conduct more rounds of sampling, their confidence in the data's availability progressively grows until it meets a specified threshold. Once this threshold is reached, the block data is considered available and valid.

The key advantage is that as more light nodes participate in this sampling process, the network's capacity to handle data increases. This, in turn, permits the scaling of block sizes without a corresponding increase in the cost of verifying the blockchain. In essence, it's akin to having a larger number of independent verifiers cross-checking the blockchain's integrity,which makes the whole system better and faster.

Staking TIA with Chorus One

As a permissionless network, Celestia uses Proof-of-Stake to secure its own consensus. Like any other Cosmos network, users can help secure the network by delegating their TIA to a validator like Chorus One. Check out our guide to stake your TIA with Chorus One using the Keplr wallet.
