Maximum Extractable Value (MEV) is critical to blockchains, particularly on networks like Ethereum and Solana. With sub-second block times and high throughput, Solana has unique challenges and opportunities in the MEV space. Unlike Ethereum's block-building marketplace model, Solana's mempool-less architecture has led to a different MEV extraction dynamic characterized by high-speed competition and potential network congestion.
Solana's unique features, including Gulf Stream for mempool-less transaction forwarding, have enabled remarkable speed and efficiency. However, these same features have also created an MEV landscape that requires innovative approaches.
The current methods of MEV extraction on Solana have several drawbacks. Searchers competing on latency often flood the network with duplicate transactions to ensure MEV capture, leading to periods of intense congestion and failing transaction processing for all users.
The winner-takes-all nature of Solana MEV opportunities results in a high rate of failed transactions. These failed transactions still consume compute resources and network bandwidths. Studies have shown that up to 75% of transactions interacting with DEX aggregators can fail during periods of high activity.
Moreover, the concentration of MEV capture among a few players threatens network decentralization as these entities accumulate more resources and influence. In Ethereum, the use of external searchers and block-builders has led to private order flow deals, resulting in extreme centralization where a single builder creating over 50% of Ethereum blocks, with only two builders responsible for 95% and four entities building 99% of all blocks.
Paladin introduces a solution to address these issues. It consists of two main components:
The Paladin bot is a high-speed, open-source arb bot that runs locally on validators. It works only when the validator is the leader and is integrated with the Jito-client. By running directly on the validator, it captures all riskless and straightforward MEV opportunities (e.g., atomic arbitrage, CeFi/DeFi arbitrage) faster than searchers, without needing to outsource these opportunities and pay around 20% of the MEV to external entities. Any non-supported, or more advanced MEV strategies that the Paladin bot doesn’t recognize can still be captured by the Jito auction, making it a net positive for the ecosystem.
The bot listens to state updates from the geyser interface, allowing real-time opportunity detection. Validators can choose which tokens and protocols to interact with, allowing more conservative validators to alleviate legal concerns about interacting directly with tokens they deem securities.
The PAL token is designed to align the incentives of validators and users and create a robust MEV extraction mechanism. With the entire supply of one billion airdropped at launch, PAL is distributed among validators, their stakers, Solana builders, the team, and a development fund.
PAL can be staked by validators and their delegators, with rewards proportional to their SOL stake. The token has a unique MEV distribution mechanism, where 10% of captured MEV is funneled to PAL token holders, with 97.5% going back to validators and their stakers. Most staked PALs can vote to slash the staked PAL of validators who engage in dishonest actions, such as running closed-source modifications of Paladin, instead of adhering to the "just run Paladin" principle.
Paladin's design creates dynamics that contribute to its sustainability. The "Pack of Wolves" dynamic incentivizes validators to "run with the pack" by honestly running Paladin. Going against the pack risks slashing and loss of rewards. This creates a self-reinforcing system of honest behavior.
As more validators run Paladin, a flywheel effect is created. More MEV is funneled to PAL holders, increasing the value of PAL and further incentivizing participation. This alignment of long-term interests incentivizes validators to behave honestly rather than pursue short-term gains through harmful practices like frontrunning.
Moreover, by allowing all validators to participate in MEV extraction, Paladin prevents centralization while still allowing searchers to implement more specialized strategies. The bot's open-source nature and transparent reward distribution create a fairer MEV landscape, benefiting the entire Solana ecosystem.
At Chorus One, we recognize Paladin's transformative potential. We've taken the proactive step of integrating Paladin into one of our Solana validators, Chorus One Palidator.
If you have been following Chorus One, you would know we have a deep interest in MEV. Almost two years back, we open-sourced our proof-of-concept called ‘Breaking Bots’ to capture MEV on Solana efficiently and ethically. Paladin’s proposition is similar in spirit but takes a different approach with the PAL token, which was not part of our proof-of-concept.
The integration of Paladin with our validator is a significant step in addressing the challenges of MEV on Solana. We invite Solana stakers to join us in this effort by delegating to our Palidator. Let’s move towards a model that benefits all participants rather than a select few.
As the MEV landscape evolves, Chorus One is committed to exploring and implementing solutions that benefit our delegators and the wider Solana community.

There are many aspects to validator performance on Solana, and different metrics are important to different people. For users of the Solana network, throughput (transactions per second) and latency (how quickly a transaction lands) are key metrics. In this article we’ll dive into two factors that affect those: skip rate and block size. We’ll explain how Chorus One is able to outperform both network average and the superminority on these metrics. If all validators performed as well as Chorus One on these metrics, Solana would be able to process 11.4% more transactions per second.
As a Solana user, when you submit a transaction, you want it to be included in the chain as quickly as possible, as cheaply as possible. When the chain can process only a limited amount of transactions per second, that means that only users who are willing to pay high priority fees can get their transaction included. When the chain can process more transactions per second, transaction processing capacity becomes less scarce, and transaction fees go down. Solana’s throughput is determined by the validators that make up the network, so for good network performance, it is important to delegate to a validator that performs well.
For this article we look at the month of July 2024. All metrics are reported over the period from midnight July 1st until midnight August 1st in the UTC time zone. (Slot 274965076 until 280826904, for those who want to reproduce our findings.)
In this article we contrast Chorus One against two groups of validators: the entire network (including Chorus One), and the superminority. The superminority is the smallest set of validators that together control more than one third of the stake. We use the superminority from epoch 650, the final epoch in July. It consists of the top 19 validators by stake.
In the Solana network, validators periodically have a duty to produce blocks. Before the start of the epoch, the protocol sets the leader schedule, which determines when every validator has to produce a block. Validators with more stake get assigned more blocks to produce.
If all goes well, when a validator’s turn comes to be the leader, the validator produces a block. The chain grows by one block, and users’ transactions get included. When things don’t go well, the leader fails to produce a block, or the block may not be accepted by the other validators. When the leader fails to extend the chain, this is called a skip, and the fraction of blocks skipped out of blocks assigned in some period of time is called the skip rate. Skips are bad for users of the network, because during a skip, no transactions get processed. Skips lower the throughput of the chain, and delay when transactions get processed. A lower skip rate is therefore better.
A validator can skip for multiple reasons. Of course a validator that is offline will be unable to produce a block, but even when it is online and produces a block, that can still result in a skip. For example, the validator could have been slightly late, and the network has already moved on, assuming the validator skipped its duty. Many of the factors that affect skip rate are directly or indirectly under the validator’s control, but some amount of skipping is inevitable in a decentralized network. During times of high activity, skip rate is generally higher network-wide than during quiet periods. Therefore, the skip rate is not meaningful in isolation, but comparing skip rate between validators is one way to judge their performance.
Over July 2024, Chorus One achieved a skip rate of 2.03%, while the network-wide skip rate was 5.19%. This means that average Solana validators fail to produce their blocks more than 2.5 times as often as Chorus One.
Maybe network average is not a fair comparison though? It may be the case that a few bad validators are pulling up the average. So let’s look at the superminority, the top validators by stake. This relatively small set of validators has the responsibility to produce one third of the blocks, so its influence on the chain’s throughput is large. Over July 2024, the superminority together achieved a skip rate of 5.68%, which is even worse than network average. Superminority validators fail to produce their blocks almost 3× as often as Chorus One.
The Solana network is effectively leaving 3.3% of its blocks on the table by keeping stake delegated to validators with high skip rates.
Aside from skip rate, a major factor for throughput is the number of transactions that every block contains. When blocks can fit more transactions, the throughput of the chain goes up. When validators are able to build larger blocks, fewer user transactions have to be postponed to the next block, so latency goes down. Furthermore, more capacity means lower transaction costs.
Over July 2024, blocks produced by Chorus One contained on average 1696.2 transactions. (This includes vote transactions that contribute to Solana’s consensus mechanism.) The network-wide average over this period was a mere 1573.3 per block. This means that Chorus One includes 7.8% more transactions per block than average validators.
Again, let’s compare this to the validators with the greatest responsibility and disproportionate impact on chain-wide throughput: the superminority. Here we see that with 1640.6 transactions per block, the superminority does outperform the network average, but nonetheless Chorus One outperforms the superminority by 3.4%.
This means that the Solana network is effectively leaving a 7.8% throughput boost on the table, by keeping stake delegated to low-performing validators. This number is only for produced blocks, we don’t count skips as zero transactions per block. This means that the 7.8% boost would come on top of the 3.3% skip rate boost. Combined, this means that Chorus One achieves 11.4% more transactions per second than average validators.
Why is Chorus One able to process 11.4% more transactions per second than other validators? As is often the case with performance optimization, there is no single trick, but if you stack enough small optimizations, the combined result can be substantial. A few of the techniques we use:
In this article we highlighted two key Solana performance metrics that matter for users of the network: skip rate and block size. Lower skip rates and larger block sizes mean that users can get their transactions included faster and for a lower fee. These two metrics contribute to how many transactions per second Solana can process. Through multiple optimizations and operational practices, Chorus One achieves 11.4% more transactions per second than the network average. If all delegators would delegate to validators who perform as well as Chorus One, Solana would be able to process 11.4% more transactions per second.

The upcoming launch of Babylon’s Bitcoin Staking Mainnet marks a significant milestone in the cryptocurrency landscape and in the evolution of Bitcoin. Babylon is redefining the utility of Bitcoin by integrating it with Proof-of-Stake (PoS) systems, offering new opportunities for Bitcoin holders. Here’s what you need to know about this launch:
1. What is Babylon Bitcoin Staking?
Babylon’s Bitcoin Staking allows Bitcoin holders to participate in the security of PoS blockchains without transferring their assets to a third party. Traditionally, Bitcoin has been seen as a store of value, but Babylon expands its utility by enabling Bitcoin to play an active role in securing various PoS ecosystems. This is achieved through a trust-minimized protocol that connects Bitcoin holders with the demand for network security across multiple blockchain systems, including PoS chains. Read our comprehensive overview of Babylon here.
2. What is Babylon’s Mainnet Launch?
The mainnet launch of Babylon represents the transition from a developmental stage to a fully operational network. This is when the protocol becomes available for public use, allowing Bitcoin holders to start staking their assets on a live blockchain. The launch is designed to be phased, ensuring that each component of the network is thoroughly tested and integrated before moving to the next stage. This approach provides a structured rollout, allowing users to gradually engage with the staking process.
3. What Are the Three Phases of the Launch?
Babylon’s mainnet launch is divided into three distinct phases, each with specific goals and functionalities:
4. What Can You Do in the Babylon Mainnet Launch?
During the Babylon mainnet launch, Bitcoin holders can actively participate in securing PoS blockchains by locking and staking their Bitcoin. In Phase 1, you can initiate staking by locking your Bitcoin in a secure, self-custodial vault on the Bitcoin blockchain. As the launch progresses into Phase 2, your locked Bitcoin will begin to contribute to the consensus process of the Babylon PoS chain. By Phase 3, you’ll have the ability to stake your Bitcoin across multiple PoS chains, maximizing your potential rewards and playing a crucial role in the security of these networks.
5. How Can You Stake Your Bitcoin?
Staking your Bitcoin with Babylon is a multi-step process that begins in Phase 1:
6. What Rewards Can You Get?
In Phase 1, there are no direct staking rewards because the PoS chain is not yet active. Instead, Babylon introduces a point system to track staking activity. These points, though they do not have direct monetary value, could potentially be used for future benefits within the Babylon ecosystem. As the network progresses into Phase 2 and beyond, your Bitcoin will earn rewards based on its contribution to the security of the PoS systems, allowing you to gain value from your staked assets.
7. Which Wallets Can You Use?
To stake your Bitcoin with Babylon, you’ll need a compatible Bitcoin wallet. The official Babylon staking web application (btcstaking.babylonlabs.io) provides a list of verified finality providers and supports most Bitcoin wallets. You can also use third-party services such as staking websites, custody solutions, or command-line interface (CLI) tools if you are more technically inclined. It’s important to choose a wallet that meets your security needs and is compatible with the staking process. Here’s a list of supported wallets:
8. What Are the Transaction Details in Phase 1?
During Phase 1, all transactions are conducted on the Bitcoin blockchain. These include:
Notably, there is no PoS slashing in Phase 1, meaning your staked Bitcoin is not at risk of being slashed for any consensus violations.
9. What Are the Limits and Caps in Phase 1?
To ensure security and broad participation, Phase 1 introduces several limits:
These caps and limits are designed to foster a secure and inclusive staking environment.
10. Eligibility and Security Considerations
Before participating in the Babylon mainnet launch, it’s crucial to ensure you meet the eligibility criteria. Staking is prohibited for residents of certain countries, including the United States, Canada, Australia, and Mainland China, due to regulatory restrictions. Additionally, Babylon has implemented robust security features, such as the covenant committee, a multi-signature verification scheme that ensures the safety and correctness of unbonding transactions.
The Babylon Bitcoin Staking Mainnet launch represents a significant evolution in how Bitcoin can be used within the broader blockchain ecosystem. By participating in this launch, you can contribute to the security of PoS systems, earn rewards, and engage with one of the most innovative protocols in the cryptocurrency space. As the launch progresses, staying informed and involved will be key to maximizing your experience with Babylon.
And that's everything you need to know to be prepared for the mainnet launch. Stay tuned and follow us on Twitter/X to stay ahead of the curve.
