F2Pool co-founder and stakefish founder Wang Chun tweeted that Oleksii Trofimchuk filed a lawsuit against Lido Finance and stakefish on September 8 in the Santa Clara County Superior Court, accusing them of allowing competing MEV bots to submit high-priority fee transactions to claim the ETH after his wallet was hacked.

On-chain data analysis platform Glassnode stated that two cities produced more than half of the Solana blocks, with Frankfurt accounting for 33% and Amsterdam for 19%.These two cities have a total of 310 validators, which represents 46% of the total 675 network validators, and 53% when calculated by staking volume.

Core DAO is coordinating an emergency hard fork due to some validators receiving CORE rewards that exceeded the protocol's expected issuance. Core stated in an update that the situation has been brought under control, and "malicious validators" can no longer claim excess rewards. This fork is a forward upgrade and will not roll back the network or revoke any confirmed transactions.Previously, Core indicated in a status update on Monday that the rewards accumulated by a small number of validators were significantly higher than the protocol's expected issuance. The incident was limited to the reward distribution phase, user assets remain secure, and they promised to release a technical review report. Following the incident, several exchanges restricted CORE transfers: Coinbase suspended deposits and withdrawals on the Core network, Bithumb and Coinone suspended deposits and withdrawals, Bitget suspended deposits and withdrawals citing wallet maintenance, and LBank suspended deposits at the request of the project party.Core has not disclosed the amount of excess issued CORE, the duration of the activity, or whether additional tokens have entered circulation, nor have they provided details on the vulnerability that allowed validators to receive rewards. Cointelegraph reached out to Core for further information but had not received a response by the time of publication.

Solana validators have voted to approve the "Dual Deflation" proposal numbered SGP-0002, increasing the network's annual deflation rate from 15% to 30%, while maintaining a long-term inflation target of 1.5%. According to the final voting results, the proposal received 67% support, 25.16% opposed, and 7.84% abstained, with a participation rate of 60.7%. The new plan is expected to bring SOL to a terminal inflation rate of 1.5% in about 2.8 years, while the original plan would take approximately 5.7 years, with an expected reduction of about 18.9 million SOL issued over the next six years.This vote marks Solana's first binding governance process, which also approved the proposed Solana Constitution while rejecting another proposal regarding resource and inclusion fees. The positions of major participants have diverged: the largest voter, Figment, holding 17.1 million SOL, cast all opposing votes, while Helius and Jupiter overwhelmingly supported it. The U.S. exchange Kraken briefly cast an opposing vote at 12:33 UTC during the voting process, causing the support rate to dip below the threshold, but ultimately over 90% of its approximately 8.9 million SOL voting position turned to support.Meanwhile, Bitwise's Solana ETF has surpassed $1 billion in assets under management, becoming the first Solana ETF to reach this milestone. According to Bloomberg ETF analyst Eric Balchunas, U.S. Solana ETFs have seen a cumulative net inflow of about $1.7 billion since their launch, with almost no sustained outflows.

The Supernova upgrade of MultiversX decouples consensus from execution, allowing the network to reach consensus on blocks before processing transactions. Before the upgrade, block production followed a sequential model: proposers selected transactions, executed them locally, and submitted blocks containing the results, while validators had to re-execute the same transactions before voting, making execution part of the consensus critical path. Supernova changes this order: proposers select transactions and directly propose blocks without prior execution; validators can immediately vote once they confirm the proposal complies with protocol rules, while execution occurs asynchronously in the background, with execution results typically referenced and notarized in the next block header, lagging consensus by about one block (approximately 600 milliseconds).To address the validity verification issues brought by decoupling, Supernova introduces a virtual memory pool state that tracks pending nonces, expected balance consumption, and transactions that have been proposed but whose execution results have not yet reached consensus, providing proposers with a forward-looking account view. Meanwhile, the Execution-Result Inclusion Estimator (EIE) limits the number of execution results that can be referenced in a block based on the capacity that the minimum specification node can safely handle; an automatic backpressure mechanism reduces block capacity when execution lags. Supernova has been producing 600-millisecond blocks on the testnet and devnet since August 20, with the mainnet expected to activate on September 10, 2026.

Cosmos Labs announced that an ongoing security incident has affected users of the Cosmos EVM module. The security and engineering team at Cosmos Labs is actively responding to the incident and has advised validators on the Cosmos EVM chain in contact with them to suspend the operation of their chain.Cosmos Labs appreciates the swift response from all teams using Cosmos EVM and stated that an incident report will be released after the situation is resolved. If relevant teams are using Cosmos EVM and have questions, they can contact security@cosmoslabs.io.

Ethereum developers proposed a "Tapered Issuance Burn" mechanism, planning to gradually burn a portion of the idealized rewards for validators as the ETH staking ratio increases; when the staking amount approaches 50% of the total supply, the net issuance of ETH will drop to 0%. The author of the proposal stated that the ETH staking ratio exceeded one-third of the total supply in April; if not adjusted, Jerome de Tychey indicated that by January 2028, the staking amount could exceed 70 million, accounting for more than 55% of the supply.Supporters believe that excessive staking may cause small independent validators to lose economic viability first, leading to staking concentration among custodial institutions and large service providers; the plan is proposed to be implemented over 18 months, with an additional approximately 6 months reserved for preparation before potential network upgrades. Aave founder Stani Kulechov stated that once the staking rate exceeds 50%, rewards will drop to 0%, and the uncertainty of returns may weaken institutional staking and DeFi demand. He pointed out that ETH lending strategies may be affected, and this proposal is still in its preliminary stage.

Coinbase released its Solana validator node operation report for the second quarter of 2026, stating that its operated Solana validator nodes outperform the network average in terms of yield, stability, and infrastructure distribution.Data shows that Coinbase currently stakes approximately 41.63 million SOL through 23 validator nodes, accounting for 9.72% of the total staked amount on Solana, with nodes distributed across 7 countries, including the United States, the United Kingdom, Germany, Japan, Singapore, and others.Key operational data is as follows: Staking scale: 41.63 million SOL, accounting for 9.72% of the total staked amount; staking yield: Q2 2026 APY is 6.52%, higher than the network average of 6.38%, leading by 14 basis points; block skip rate: 0.035%, lower than the network average of 0.136%, about one-fourth of the network average.Coinbase stated that its validator nodes adopt a multi-client architecture, currently running 4 clients including Harmonic, Jito, JitoBAM, and Firedancer. All solutions have been reviewed by the Solana Foundation, and aggressive MEV time strategies that may affect user experience are not used.In terms of infrastructure, Coinbase has deployed its validator nodes on two independent bare-metal service providers and configured off-site backups for each node to reduce single points of failure risk. At the same time, the company stated that it has migrated the entire validator node cluster to the DoubleZero network, achieving approximately 99.9% session availability.Coinbase also revealed that it is preparing for the Alpenglow consensus upgrade expected to be advanced by Solana later in 2026, including running community test nodes, developing new consensus health monitoring tools, and completing related voting account upgrade verification.

Circle announced that its open blockchain network Arc, aimed at the global financial market, will officially launch on the public mainnet on September 16. It is currently operating on a private mainnet and has attracted over 100 institutional and ecosystem participants. BlackRock, DTCC (Depository Trust & Clearing Corporation), Galaxy, Global Payments, ICE, Mastercard, MoneyGram, SBI Group, Standard Chartered Bank, Sumitomo Corporation, and Visa will participate as genesis validators for network security and governance.BlackRock plans to deploy its dollar institutional digital liquidity fund BUIDL on Arc, while DTCC is advancing the tokenization and settlement integration with Arc, supporting the tokenization of assets held at DTC to Arc for on-chain settlement based on stablecoins. Circle also plans to launch a supporting application framework, AI tools, and tokenized asset issuance management capabilities on Arc.

Ethereum's largest liquid staking protocol Lido announced the launch of the largest protocol upgrade since the V2 upgrade in 2023, which will integrate over 8 million staked ETH (approximately $16.5 billion) and migrate to the new validator architecture following the Ethereum Pectra upgrade. This migration is expected to reduce the number of Ethereum network validators by about one-third, lowering the load on the consensus layer.Lido stated that after the upgrade is completed, the number of attestation messages per epoch across the entire Ethereum network is expected to decrease by about 29%, thereby improving network operational efficiency. This upgrade will migrate professional node operators to the Curated Module v2 (CMv2) architecture. Unlike before, which mainly relied on operator reputation and historical performance, CMv2 requires Lido-selected node operators to lock ETH as collateral for the first time, providing economic guarantees for node operational performance.Lido indicated that all 34 selected node operators are expected to complete the migration, and no operators have exited due to the new collateral requirements. Lido's staking lead Isidoros Passadis stated that this upgrade will streamline the validator set supporting Lido's core staking business while enhancing security through capital constraints. Lido expects that this migration will result in a decrease of approximately 0.28% in annual staking yields for the protocol. Validators will continue to earn rewards before exiting the migration, with any yield loss likely occurring only during the brief period before balances are transferred to the new validators.

Ethereum Improvement Proposal EIP-8222 aims to separate staking deposits from withdrawals through a STARK-based cryptographic mechanism and to re-anonymize validators to reduce the traceability of validator activities. Currently, about one-third of ETH is staked.Thibault Dubuis, Head of Staking and Decentralized Finance Products at Sygnum Bank, stated that the current deposit addresses, validators, and withdrawal credentials create visible links, making institutional holdings, entry times, and staking strategies nearly public. This proposal is still in the discussion phase and has not yet scheduled a deployment time. Its design may involve arrangements such as fixed deposit denominations and asset withdrawal waiting periods, and institutional users may need to bear higher execution costs, process delays, and compliance work.

According to ValidatorQueue data, the current Ethereum validator entry queue size is 2,499,792 ETH, with an expected waiting time of 43 days and 10 hours; in contrast, the exit queue has dropped to 0, and the exit waiting time shows as 0 minutes, but complete withdrawal of funds after exiting still takes about 7.7 days.Data shows that the current number of active Ethereum validators is 883,724, with a total staked amount of approximately 40.8 million ETH, accounting for 33.49% of the total supply, and the current staking APR is 2.64%.

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%.
