validator

According to CoinDesk, the Ethereum Foundation recently disclosed that its security team used AI agents to test the software running on Ethereum validator nodes and successfully discovered a remotely triggerable vulnerability that could cause node crashes. However, researchers emphasized that human review remains a key step in distinguishing real vulnerabilities from false positives among the large number of security reports generated by AI.It is reported that the discovered vulnerability exists in the Ethereum network message propagation protocol gossipsub, where an attacker can remotely trigger the node software to enter an abnormal computation state, causing the program to crash and shut down, making the validator node go offline until the operator manually restarts it. This vulnerability has been fixed and registered under the identifier "CVE-2026-34219."Nikos Baxevanis, a member of the Ethereum Foundation's protocol security team, stated that what was truly surprising about this incident was not the AI's ability to discover vulnerabilities, but rather the amount of time the team spent discerning which vulnerabilities were real and which were merely seemingly credible "illusions."

Ethereum co-founder Vitalik Buterin published the proposal "The Extremely Lean Chain," demonstrating how to radically compress the state requirements of the Ethereum consensus chain in the context of the "Lean" upgrade. This plan shifts responsibility to validators, who manage and periodically prove their state through ZK proofs, thereby eliminating the processing burden for each epoch and potentially supporting millions of validators.The core mechanisms include: removing the validator public keys from the on-chain state, storing only the deposit tree index; canceling real-time reward and penalty processing, with validators generating daily STARK proofs of their participation and updating balances; completely re-randomizing validator identities daily, achieving strong anonymity through ZK-STARK, with withdrawal addresses exposed only at the time of withdrawal and not publicly linked to deposits or on-chain activities. Vitalik stated that based on upgrades such as single-slot finality and quantum-resistant signature aggregation, the state requirement per validator could be compressed from approximately 180 bytes to 6 bytes. The daily proof cost for a single validator requires processing about 5400 Merkle branches, which can be completed within 1 hour on ordinary hardware, and the on-chain burden can be reduced through aggregated proofs. Additionally, this design can achieve a "virtually free" single secret leader election function, with 1 day as the conservative cycle length and 1 hour as the lower limit.

Sharplink Co-CEO and former Blackrock executive Joseph Chalom stated that Ethereum has over 900,000 validators and more than 1,000,000 developers, possessing a decentralization advantage that Solana cannot match.Data from Electric Capital shows that 1,012,824 developers have contributed code to Ethereum, with approximately 232,000 remaining active over the past 12 months.Chalom noted that Solana has fewer than 800 validators, with 92% running on the same client. Data shows that Sharplink held 886,725 ETH as of late June.

According to Cointelegraph, Polkadot OpenGov recently proposed two new staking proposals (Proposal #1909 and #1910) aimed at strengthening validator incentives, eliminating the nominator penalty mechanism, and reducing the unbonding period from approximately 28 days to 2 days.

According to The Block, payment company MoneyGram has become a validator on the Solana blockchain and joined the Solana Developer Platform, officially entering the Solana ecosystem. Solana is the third public blockchain where MoneyGram operates as an official validator, having previously operated validators on Tempo and Midnight Network.MoneyGram CEO and Chairman Anthony Soohoo stated that serving as a validator allows MoneyGram to stake SOL, process transaction blocks, and contribute to the security and performance of the Solana network. Joining the Solana Developer Platform enables it to gain tool support for building and issuing financial products alongside institutions like Mastercard.

According to CoinDesk, the Ethereum research forum has released a new proposal introducing the "validator redirect revenue" mechanism, allowing validators to redirect 0% to 10% of staking rewards to fund ecosystem infrastructure and public goods. If a majority of validators support a certain percentage, that percentage will be enforced for all validators. Based on current staking levels, a redirect of 5% to 10% could bring approximately 50,000 to 70,000 ETH to the ecosystem each year, equivalent to about 120 million dollars.The proposal aims to address the long-standing "free-rider" problem in Ethereum, but it has also raised concerns about the risks of validators jointly manipulating the flow of funds and the misalignment of interests between staking operators and ETH holders. The proposal is currently still in the discussion phase and has not yet entered the formal voting process.

According to Coindesk, Bittensor developers have submitted a new proposal called "Root Reborn," which aims to change the revenue distribution mechanism for Root network stakers.Currently, the revenue for Root network stakers is paid by selling subnet tokens for TAO, which continues to create selling pressure on subnet tokens. The new proposal will allow validators to actively choose a combination of supported subnets and reinvest the revenue originally intended for sale into these subnets, forming a basket of assets that compounds over time.This move will convert the ongoing selling pressure into net buying demand for subnet tokens, while transforming validators from passive revenue channels into active selectors similar to fund managers. Stakers will still receive revenue and can exchange subnet assets for TAO at any time.The proposal has currently only been submitted to the testnet and has not yet been deployed to the mainnet. It is reported that TAO has dropped 28% in the past 12 months, and the current annualized yield for Root network staking is approximately 17%.

Data from beaconcha.in shows that there are approximately 2.8841 million ETH in the Ethereum validator entry queue waiting to be staked. Based on the rate of processing 256 validators per epoch, new participants need to wait 50 days and 2 hours to officially participate in staking. There are only 89,800 ETH in the exit queue, with a waiting time of 1 day and 13 hours, and it will take an additional 7.7 days for the funds to be automatically withdrawn. Currently, there are about 888,000 active validators on the network, with a total staked ETH amount reaching 39.5 million, accounting for 32.45% of the total ETH supply, and the current annualized staking yield is 2.74%.

According to CoinDesk, Tom Lee, Head of Research at Fundstrat and Chairman of Bitmine, stated at the Proof of Talk conference in Paris that he expects Ethereum to eventually reach $250,000, with artificial intelligence and tokenization driving significant changes in financial infrastructure. Lee pointed out that with the arrival of the machine-to-machine economy, Ethereum will transition from a speculative digital asset to a major global currency for payment automation and computational processing power.Bitmine recently acquired 111,942 ETH, increasing its holdings to nearly 5.4 million ETH, accounting for about 4.47% of the circulating supply. Lee stated that Bitmine is now eligible for inclusion in the Russell 1000 index, with its staking model outperforming holding spot ETH. He believes that enterprise validators will replace the shrinking Ethereum Foundation as key managers of the network, with corporate entities currently jointly controlling 7% of Ethereum's circulating supply.Lee mentioned that if Ethereum achieves the $250,000 target, Bitmine's stock price will reach $5,000. He also noted that the current bearish sentiment indicates the market bottom for Bitcoin and Ethereum, suggesting that selling during bearish times is akin to selling at the bottom.

Coinbase released the Solana Validator Performance Report for the first quarter of 2026, disclosing its staking scale, infrastructure upgrades, and network optimization progress. It revealed that Coinbase has staked approximately 40.48 million SOL on the Solana network, accounting for 9.52% of the total network staking, with validator nodes distributed across 6 countries/regions.The report also noted that Coinbase has implemented a near-zero downtime (ZDD) upgrade mechanism, ensuring that the validator update process does not affect network security and stability through hot swapping and dual-signature protection. It supports multi-client systems such as Harmonic, Jito, JitoBAM, Firedancer, and Rakurai to enhance the diversity and resilience of the Solana validator ecosystem while avoiding the centralization risks of a single scheduling strategy.

Polkadot posted on X that OpenGov is voting on significant changes to the network staking architecture. Referendum 1890 proposes that validators on Polkadot must lock at least 10,000 DOT as self-staking.This reform is a mandatory prerequisite for the next phase of staking upgrades, which include immunity from slashing for nominators and quick unbonding (approximately 24-48 hours instead of 28 days). The logic is to allow validators to absorb slashing risks directly through significant self-staking exposure, while nominators can continue to earn staking rewards without exposing their principal. If passed, Polkadot staking will eliminate two major barriers to participation, thereby reducing the risk for nominators and shortening exit times.

The Solana development company Anza announced that it has officially recommended the mainnet validators upgrade to Agave 4. This upgrade introduces XDP for Turbine, QUIC-only TPU data access, a faster replay stage, and several SIMD features that will be activated during this cycle.Anza stated that production environment tests on large mainnet validators showed that XDP has reduced the Turbine retransmission delay from about 600 ms to approximately 0.8 ms, providing critical performance headroom for Solana's push towards 100 million CU blocks. Additionally, Agave 4 has completely removed UDP transaction access, making QUIC the only transaction submission method; PoH entry verification and Ed25519 signature verification have also been removed from the critical path and processed asynchronously to enhance replay stage performance.This round of upgrades will also gradually enable several SIMD features, including p-token (an SPL Token alternative that can free up about 13% of block capacity), Stake Program v5, SBPFv3 support, pre-funded account creation, and BLS12-381 syscall, among others.

Anatoly Yakovenko (toly), co-founder of Solana Labs, responded to discussions about the decentralization level of Hyperliquid, stating that he has raised the same criticism for all L2s: the key to determining whether a system is permissionless lies in whether users can participate in any part of the protocol stack using their own resources without approval from a trusted third party.If they cannot, it is not permissionless. Toly stated that no matter what users do, they cannot run the Base sequencer or the Hyperliquid sequencer, so this is the same issue he criticized with L2s.

Coinbase released the Ethereum validator performance report for Q1 2026. The data shows that its validators currently have a total of 4.5 million ETH staked, accounting for 12.17% of the total staked ETH on the Ethereum network. Coinbase stated that it commits to not exceeding a 30% validator penetration rate on the Ethereum network.The report indicates that Coinbase validators are deployed in five regions: Germany, Hong Kong, Ireland, Japan, and Singapore, with an average online rate of 99.98% in Q1 2026, higher than the network average of 99.77%.In addition, Coinbase claims that its validators have not experienced any slashing or double-signing events since going live, currently utilizing two consensus layer clients, Lighthouse and Prysm, as well as three execution layer clients, Geth, Nethermind, and Reth.

Telegram founder Pavel Durov posted on the X platform that the TON network transaction fees have been reduced by 6 times.He also revealed that Telegram will replace the TON Foundation as the largest validator of the network and plans to launch new development tools and performance upgrades in the next 2 to 3 weeks.

Telegram founder Pavel Durov stated in his personal channel that the TON network transaction fees have decreased by about 6 times, and are currently approaching "almost zero" levels.Key adjustments for the next phase include: Telegram will replace the TON Foundation as the main driving force behind TON, Telegram will become the largest validator on the TON network, and the focus of the ecosystem will shift towards technical performance and infrastructure optimization; updates to the technical roadmap include: the launch of a new ton.org, the release of a new generation of developer tools (dev tools), and upgrades to network performance and scalability, with related upgrades expected to be implemented within 2-3 weeks.

The Ethereum liquid re-staking protocol Ether.fi announced that it will provide a total value of $3 billion worth of Ethereum as "validator liquidity" to the ETHGas market over the next three years, funded by the 2.8 million staked Ethereum it manages.ETHGas is a futures market for Ethereum block space that allows for the advance purchase of block space to ensure transaction execution. This initiative aims to enhance validator earnings by helping validators capture more maximum extractable value (MEV) through the sale of block space commitments, resulting in higher and more predictable returns. ETHGas has received institutional investments from firms like Polychain Capital and has launched the governance token GWEI, which currently has a market capitalization of approximately $120 million.Ether.fi's native token ETHFI has a market capitalization of about $332 million. This move will provide developers and enterprises with more predictable transaction costs and execution times, promoting the development of Ethereum as a global institutional capital settlement layer.

According to Theblock, institutional payment giants Visa and Stripe, as well as Zodia Custody under Standard Chartered Bank, have become early validators of Tempo.It is reported that Tempo is an Ethereum-compatible Layer 1 built for high-throughput payments and stablecoin settlements. The project is incubated by Stripe and Paradigm and launched on a private testnet in September. At the same time, Tempo also launched a proxy payment protocol aimed at enabling transactions through software proxies.

According to The Block, Ethereum researchers are exploring the "Block-in-Blobs" proposal (EIP-8142), which plans to encode block execution load data into Blobs. Validators can verify data existence through Data Availability Sampling (DAS) without needing to download the complete dataset, reducing bandwidth pressure and improving scalability.In the zkEVM scenario, this proposal can also fill the gap where zero-knowledge proofs cannot guarantee data availability and aims to unify execution Gas and Blob data usage into a single "data Gas" system.In addition, Biconomy, in collaboration with the Ethereum Foundation, proposed ERC-8211, which supports executing multiple operations in sequence under a single signature to reduce failed transactions and optimize the DeFi interaction experience.

According to the official blog, Circle's institutional-grade blockchain Arc has released a phased upgrade roadmap for post-quantum cryptography (PQ), planning to introduce post-quantum signature schemes at the launch of the mainnet, gradually covering full-stack layers such as private state protection, infrastructure hardening, and validator authentication.The Arc mainnet will support post-quantum signatures from the outset, using an opt-in mechanism that does not require mandatory migration or a full network reset, allowing users to independently create wallets with long-term security. The recent goal is to extend quantum resistance to the private virtual machine (VM) layer, protecting private balances, private transactions, and private payees, with public keys additionally encapsulated in a symmetric encryption layer under privacy mode.The mid-term plan is to advance the upgrade of the infrastructure layer, aligning with industry standards such as TLS 1.3, covering access control, cloud environments, and hardware security modules (HSM). The long-term goal is to complete the hardening of validator signatures. Given that Arc's block finalization time is less than 1 second, the current assessment considers the risk of quantum attacks in this phase to be relatively limited, and it will be steadily advanced after the post-quantum consensus toolchain matures.Circle also warns that attackers may adopt a "collect now, decrypt later" strategy, and institutions should plan their cryptographic migration paths as early as possible.
