The TON blockchain has emerged as a promising platform, but for institutions (wallets, exchanges, custodians etc.) looking to offer Toncoin staking to their customers, current options come with serious limitations. From high staking minimums to complex pool management, existing solutions fall short of meeting the needs of large-scale, flexible staking.
Recognizing this gap, we have launched TON Pool – a staking solution designed to meet the unique requirements of institutional players while making Toncoin staking simpler, more efficient, and scalable.
The TON ecosystem currently offers the Nominator Pool and Single Nominator contracts as staking options. However, both models restrict the number of delegators and impose high minimum stake requirements, which limits accessibility for larger institutions that manage staking services for numerous clients. These limitations force institutions to distribute stakes manually across multiple pools, adding operational complexity and increasing transaction fees, while impacting the final yield. (We covered the current TON staking mechanisms in detail here.)
With these pain points in mind, we saw an opportunity to create a tailored solution that eliminates these barriers and optimizes staking for our customers needs.
TON Pool addresses the shortcomings of current models by providing a flexible, high-efficiency staking solution that scales for larger institutions and various service providers. TON Pool aggregates Toncoin from an unlimited number of users into a single pool, offering seamless in-protocol distribution across multiple validators and removing the need for complex management. The result? A more streamlined, cost-effective, and yield-optimized staking experience for institutions and their customers.
TON Pool is designed for:
One of the most significant advantages of TON Pool is its streamlined staking flow. Here’s a comparison of how staking works with traditional models versus TON Pool:
With TON Pool, customers no longer need to juggle multiple addresses or pay per transaction. Instead, they delegate once, paying a single fee, while all technical complexities are managed seamlessly within the protocol.
“TON Pool is our answer to the challenges institutions face when staking on the TON blockchain. We built this solution to remove unnecessary steps, lower costs, and provide a scalable option for institutions that require a higher degree of flexibility. TON Pool makes staking more accessible and profitable, which we believe is essential to driving the TON ecosystem forward,” - Brian Fabian Crain, CEO, Chorus One.

In the context of Ethereum and Proof-of-Stake (PoS) networks, the Annual Percentage Rate (APR) is often presented as a clear and accessible measure of validator performance. As a summary statistic, APR seeks to answer a straightforward question: If I stake 32 ETH today, how much can I expect to have after one year?
However, APR is fundamentally an oversimplification of a highly complex system. Its role as both a measure of past returns and a forecasting tool obscures the intricate dynamics that govern validator rewards on Ethereum.
For example, using APR to predict future returns is like:
- > Using a small sample of stocks from the S&P 500 to estimate the average yearly return —similar to how APR behaves for small validators.
-> Using just 1-2 years of S&P 500 data to forecast long-term returns —similar to relying on short-term APR data like 7-day or 30-day rates.
This article aims to unpack the underlying biases of APR, explore the stochastic nature of validator rewards, and propose alternative metrics that offer a more accurate assessment of node operator performance—metrics which align more closely with operational realities. Finally, we will examine how Chorus One’s approach, incorporating our proprietary MEV-boost fork, Adagio, captures a more refined understanding of Ethereum staking dynamics. By optimizing the interaction with Ethereum’s proposer-builder separation, Adagio allows us to consistently improve validator efficiency, resulting in tangible improvements in performance without relying on the variability of APR metrics.
Ethereum validators are compensated through two primary reward streams:
While the attestation process is deterministic, rewards from block proposals and MEV are inherently probabilistic. This variability introduces a fundamental challenge: APR assumes a uniform distribution of rewards across validators, which is far from reality. The skewed nature of the reward distribution makes APR a poor proxy for expected returns, especially over shorter time horizons.
The central flaw in using APR as a measure of validator performance lies in its failure to account for the randomness that defines much of the reward structure. To illustrate this, consider the following:
As these rewards are driven by skewed distributions, their mean value—a key input for APR—becomes a biased estimator. Skewness is a measure of how asymmetrically data is distributed , see e.g. here. In probability theory, the mean of a skewed distribution is a poor representation of the typical outcome. Validators who are fortunate enough to receive multiple block proposals or sync committee assignments will see a disproportionately higher APR compared to validators who, through no fault of their own, are assigned fewer opportunities.
To further understand how randomness impacts APR, it is useful to visualize the reward distribution for validators operating at different scales.
The plot above shows how reward skewness changes based on the number of validators controlled. Precisely, higher is the skewness, longer is the upper tail, indicating that the overall distribution is asymmetric on the right. The consequence is that the mean is higher than the median. MEV rewards are the most skewed (bottom-right), meaning they vary the most between validators. Sync committee selection also has a significant impact (top-left), while block proposals have the least skew (bottom-left).
What’s clear is that as the number of validators increases, the skewness in rewards drops significantly. This means larger validator sets see more consistent rewards, while smaller sets face more variability due to randomness. The same holds true even by accounting for only a smaller time period instead of the whole year data.
-> This highlights why APR, when viewed in isolation, is not a reliable measure of performance, particularly for node operators running fewer validators.
This plot shows the distribution of simulated APR assuming different number of validators controlled. It is evident how the APR becomes reliable only when the number of controlled validators is high compared with the number of active validators (purple and cyan histograms). This is because, as we saw earlier, when more validators are controlled, the skewness in rewards decreases, making APR more reliable.
It is worth noting that, the aggregate APR of an entity controlling more validators is not the APR of a single customer, usually holding a lower number of validators. In this case, the APR of the small subset is affected by higher variance as in the case of low number of validators controlled.
However, when rewards are pooled—such as in solutions like Chorus One’s ETH staking vault on Stakewise —this variance is minimized. By pooling rewards across many validators, customers gain exposure to the performance of top-tier node operators while benefiting from a more consistent and stable APR.
In light of these insights, what should we look at when evaluating a validator’s true performance? A more reliable framework involves focusing on the operational aspects that are within the control of the validator:
These metrics provide a far more grounded understanding of validator performance than APR, which often serves more as a reflection of stochastic luck than actual skill or operational consistency.
At Chorus One, we approach Ethereum staking with a deep commitment to performance optimization. While APR figures may fluctuate due to the randomness of block proposals, we have developed sophisticated tools to maximize validator returns and minimize variance.
Central to this approach is Adagio, our internally optimized MEV-boost client. Adagio improves Execution Layer rewards by optimizing the way we interact with block builders. Specifically, we have introduced latency parameters that allow us to extract higher MEV rewards without compromising slot accuracy. This gives our validators a distinct advantage in capturing Execution Layer rewards, effectively smoothing out the variability that undermines traditional APR metrics.
Moreover, our focus on uptime and effectiveness ensures that our validators consistently outperform industry benchmarks. By maintaining near-perfect operational performance and leveraging cutting-edge tools like Adagio, Chorus One is able to deliver superior returns over the long term, irrespective of the randomness that defines APR calculations.

Over the past 30 days, Adagio has delivered an 8.45% increase in MEV rewards compared to a standard configuration without Adagio.

APR, while often used as a shorthand for node operator performance, is a fundamentally flawed metric. Its reliance on skewed distributions and random events, such as block proposals and sync committee participation, makes it a biased estimator for expected returns. Instead of focusing on APR, a more reliable approach to evaluating validator performance involves analyzing metrics like effectiveness, uptime, and frequency of fulfilled duties.
At Chorus One, our focus on operational precision and technical advancement allows us to consistently deliver reliable performance. With solutions like Adagio, we enhance reward optimization, offering staking outcomes that navigate the inherent volatility and randomness of APR-based assessments.

Ethereum’s continuous drive for innovation has brought us through various transformative upgrades over the years. From the transition to Proof of Stake with The Merge to the improved fee structures of the London hard fork, Ethereum has proven time and again that it can adapt, scale, and evolve. Now, the Ethereum community is on the cusp of something even more significant: the Pectra upgrade—Ethereum’s most ambitious overhaul yet.
The Pectra upgrade, poised to begin its roll out in early 2025, promises to push the boundaries of Ethereum's scalability, security, and efficiency, each focusing on different aspects of Ethereum’s architecture. These enhancements will ensure Ethereum is equipped to handle the next phase of decentralized applications and economic activity.
This introductory article will give you a comprehensive overview of Pectra, explain the rationale behind splitting the upgrade into two phases, and provide a sneak peek into the key staking oriented Ethereum Improvement Proposals (EIPs) that will shape the network’s future. In subsequent articles, we will dive deeper into each major EIP, exploring their implications for both developers and users.
The decision to split Pectra into two phases—Pectra A and Pectra B—was driven by the growing complexity of the planned upgrades. To manage this scope without introducing bugs or security risks, Ethereum developers opted for a phased approach, with Pectra A launching in early 2025 and Pectra B following later in the year. This approach allows for a smoother, more controlled rollout, giving developers the time to test and refine each change thoroughly.
Pectra A focuses on critical improvements such as reducing node data storage through Verkle Trees, which will lessen the load on validators, as well as introducing "smart account" features and other staking changes, like MAX-EB.
Pectra B, while not yet finalized, is expected to include PeerDAS, a feature aimed at enhancing Layer 2 scalability, along with changes to the Ethereum Virtual Machine (EVM).
Each phase of Pectra comes with its own set of EIPs, aimed at enhancing Ethereum’s performance, security, and developer experience. Some key staking-related EIPs confirmed for the first phase include:

The Pectra upgrade is more than just a technical enhancement—it represents the future of Ethereum. By addressing critical issues such as scalability, transaction costs, and decentralization, Pectra prepares the network to handle the demands of tomorrow’s decentralized applications.
In the following articles, we'll explore these EIPs in greater detail. From streamlining staking operations to the benefits of "MAX-EB," we’ll examine how these changes will impact the ecosystem, particularly in the realm of staking, and why they’re crucial to Ethereum's continued growth.
Stay tuned as we unpack each EIP and see how Pectra will redefine Ethereum for the years to come.
