validator

Solflare announced that new validators are now online. Users can now manually unstake from Solflare (Legacy) and stake to the new validators, or wait for the application update to migrate.The official team will compensate for the rewards interrupted during the migration period, with specific duration and details to be announced later.

EIP-8450 proposal update, intended to introduce a quantum-resistant public key registration mechanism for Ethereum validators, using a hash-based cryptographic scheme, including leanXMSS keys and VRF tree roots.The update clarifies that the registration and replacement of quantum-resistant keys are authorized by BLS signature keys, and sets a replacement delay of at least one Epoch and a replay protection mechanism; this proposal is currently still in the Draft stage and has not yet been deployed.

According to official news, Jupiter has partnered with BitGo to launch a validator for institutions. BitGo's institutional clients can now directly use Jupiter to stake SOL through their existing custody accounts.

According to SolanaFloor, Solflare stated that its staking service provider experienced a security incident that affected the keys held for its validators, which are no longer generating staking rewards. Solflare claimed that user funds were not affected, and the delegated SOL remains in the users' own staking accounts, controlled by their keys.Solflare will guide users to migrate to new validators through an app update, and rewards will resume once staking is activated, with plans to compensate migrating users.

On October 24, Solana co-founder Anatoly Yakovenko (Toly) posted an idea on X, planning to utilize Solana validators to build an oracle that allocates voting power based on staking weight, providing price assessments for tokenized assets and using such assets as collateral.According to this concept, validators will participate in price judgments based on the amount of SOL they have staked. The profits generated by the related mechanism could increase revenue for the Solana network through taxation. However, this idea is still in the conceptual stage and is not a formal governance proposal, with no clear implementation timeline or governance voting arrangements at present. If realized in the future, this mechanism could introduce a native alternative to Solana's existing oracle network, but it also involves supply changes brought about by the increase in SOL issuance, as well as potential conflicts of interest and manipulation risks arising from validators participating in collateral pricing.

Lido has launched 0x02 CSM, allowing permissionless operation for validators with a maximum effective balance of 2048 ETH. Operators do not need to self-fund the staking deposit; they only need to provide a bond. The first key requires 32 ETH, and subsequent keys require 30 ETH, with staking allocated by the protocol.This module adopts an initial deposit queue and an additional staking queue with a limit of 32 seats; the initial share cap upon launch is 0.01% of Lido Core TVL, and the first batch of approximately 32 keys will receive seed deposits.

Solana's largest network upgrade since 2020, Alpenglow, officially launched on Wednesday. This upgrade moves validator voting from on-chain to off-chain, packaging votes into certificates that can lock transactions within one to two rounds, aiming to reduce the final confirmation time for transactions from about 6 seconds to approximately 150 milliseconds, speeding it up by about 40 times. If this goal is achieved on the mainnet, Solana's transaction settlement speed will be faster than the blink of an eye, bringing it closer to the trading and payment experience of centralized exchanges.Currently, a 6-second confirmation time means that prices may change before the transaction is locked, causing exchanges and payment applications to wait before considering deposits as complete. In comparison, Ethereum takes about 13 minutes to achieve full final confirmation. At the same time, validator costs are expected to decrease by about 60%: currently, validators spend about 2 SOL daily on voting fees, which doubled after Solana recently reduced block time to about 200 milliseconds; Alpenglow eliminates voting fees, replacing them with a fixed validator entry fee of 0.8 SOL per epoch (approximately 24 hours).The upgrade launch process was not smooth. The testnet has been cleared and restarted from scratch six times since its launch in early May, with one migration failing across the entire network and having to be rolled back. According to an article published by Galaxy Digital, one of about 100 validator operators on the testnet, a subsequent migration was successfully completed, clearing the way for Wednesday's launch. Since these events occurred on a network built specifically for testing, there was no risk to real funds. The upgrade was scheduled to switch at the start of epoch 1064 on Wednesday, with actual changes occurring at slot 459,653,000 after a transition of 5,000 slots.

The founder of the Solana landing service analysis platform Circular, Ben, stated that he believes the trading terminal Axiom charges traders through misleading "validator bribes" and routes the related funds to the landing service Lunar under HelloMoon. Ben mentioned that since April, the bribes paid by Axiom traders to Lunar amount to approximately $55.7 million, but the latest 30-day analysis shows that only about 1% can be traced back to additional on-chain validator incentives, and he inquired whether Axiom shares in this tip revenue.Circular claims that it reconstructed the activities related to Lunar and Axiom from April 26, 2026, to October 19, based on on-chain payment flows: during this period, Lunar received 530,166 SOL in bribes, valued at approximately $55.67 million based on its quoted price of $105/SOL, corresponding to 189 million successful payments of bribes to Lunar from Axiom transactions. In the last 30 days, 45 million Axiom transactions made payments to Lunar, accounting for 80.6% of successful Axiom transactions; Lunar received 138,964 SOL, approximately $14.59 million, of which about 1,579 SOL was attributed to additional on-chain validator incentives, accounting for 1.14%.Ben also cited on-chain cases from September 26 and October 7, stating that after he paid bribes as suggested by the Axiom interface, the identifiable additional priority fee increase was about 1% of the amount paid to Lunar. He indicated that Axiom controls transaction routing and fee recommendations and has published its associated Lunar address on GitHub for verification. The above content represents Circular's on-chain statistics and personal judgment, and the post also states that the related proportions do not exclude other service costs or off-chain payments, and its estimate of the platform's revenue share is not based on tracked payments to Axiom.

A network startup company called Optimum, led by Professor Muriel Médard from the Massachusetts Institute of Technology, announced that its block propagation software mump2p has officially launched on the Ethereum mainnet. The Ethereum liquid staking protocol ether.fi has made mump2p a mandatory requirement for all 12 of its node operators, whereas previously the software was optional for its operators.Optimum stated that there are currently 16 node operators running mump2p in production environments, collectively managing approximately 22,000 validator keys and over 1.4 million staked ETH, accounting for more than 3% of the total staked amount on Ethereum. Partners include Blockdaemon, Everstake, P2P.org, Stakefish, and Bitcoin Suisse. The software operates in a sidecar gateway manner, not replacing Ethereum's default GossipSub, but rather overlaying it on top of libp2p and utilizing random linear network coding technology. Optimum claims that the block arrival speed is 2.42 times faster than GossipSub, with an approximately 7.88 times reduction in arrival time variance.Rok Kopp, co-founder and Chief Growth Officer of ether.fi, stated that they will not require the entire validator set to adopt a new infrastructure unless they are confident that it can enhance the overall level of stakers and the network. Médard mentioned that traditional financial institutions invest billions of dollars to shorten execution times to the millisecond level because speed is money. Optimum launched its private testnet in June 2025, having previously completed a $11 million seed round financing led by 1kx, and plans to expand the protocol to other high-throughput blockchains after Ethereum.

According to The Defiant, the modular data availability network Celestia has announced the activation of Fibre services, opening a channel for Rollups to upload data directly to validators. Fibre is a data publishing protocol launched by Celestia that allows clients to upload blob data shards to Fibre servers operated by validators and download data from these servers, bypassing traditional relay transmission paths.According to Celestia's documentation, Fibre encodes each blob with erasure coding, enabling readers to recover complete data from partial encoded lines. The consensus layer only records payment information and blob commitments, while the data payload is transmitted directly between the client and the Fibre servers. The storage budget for each server is determined by the staking amount of its corresponding validator, and starting from application version 10, each bound validator is expected to run a Fibre server.Celestia stated that the design of separating data from commitments allows the chain to only handle commitments and validator signatures on-chain, without carrying the data itself, thus supporting higher throughput. In an end-to-end benchmark test involving 120 validators, Fibre achieved a throughput of 3.07 Tb/s. This feature provides a more efficient data publishing path for Rollups built on Celestia.

The XRP Ledger vulnerability fix package named fixCleanup3_4_0 is expected to officially take effect around 09:34 UTC on October 23. This fix package has received votes from 29 validators, surpassing the threshold of over 80% approval among the network's default 35 validators, and must be maintained continuously for two weeks. The countdown has been ongoing for nine days. Since there is no margin in the vote count, if any validator withdraws support, the countdown will restart.This fix package partially addresses the unsecured lending system that Ripple has been promoting to banks and payment companies since June, but this system has not yet been activated. Currently, the lending amendment has only 19 votes, and the vault amendment for holding funds has 21 votes, neither of which has started the countdown. Therefore, even if both reach 29 votes today, the lending function will not be available until early November at the earliest.As designed, lenders will deposit XRP or other tokens into the vault, and loan brokers will then lend out the funds for a fixed term. The ledger is responsible for recording the loans and tracking repayments, while brokers assess the borrower's qualifications off-chain. Since borrowers do not need to provide collateral, the broker's judgment becomes the only guarantee for lenders against default losses. Ripple has promoted this scheme to payment companies that need liquidity during cross-border settlement. Additionally, the fix package also closes a vulnerability that allowed accounts authorized to destroy tokens to create new tokens under specific conditions and adjusts the rounding of vault amounts as well as the rules for determining loan overdue and default.

According to The Defiant citing data from Beaconcha.in, the number of active Ethereum validators has decreased by 2.5% over the past 7 days, to approximately 863,000, while the total amount of staked ETH has slightly increased by 0.08%, reaching 43.74 million.The decline in the number of validators is mainly related to the validator merging mechanism after the Pectra upgrade. This upgrade raised the maximum effective balance of a single validator from 32 ETH to 2048 ETH, allowing operators to merge multiple validators without needing to exit staking, thereby reducing network communication and consensus overhead. Currently, approximately 507,000 ETH are in the merging queue, with an expected waiting time of about 5 days and 11 hours.

Solana real-time application project MagicBlock announced on X that MagicBlock v1.0 has launched on Solana, after approximately a year and a half of development.MagicBlock stated that the application can run in real-time without leaving Solana, proving the fairness of each result while maintaining payment privacy. The team also released the complete documentation for Validator v1.0.

According to CoinDesk, Ethereum developers released version 7.2.1 of the Prysm client on Monday evening, embedding a 200 million Gas limit to complete deployment ahead of the Sepolia testnet testing for the Glamsterdam upgrade on Tuesday.Glamsterdam is the next major upgrade for Ethereum, which will first be activated on the Sepolia testnet, where developers rehearse changes using tokens with no actual value. Part of Tuesday's testing involves raising the Gas limit on Sepolia from approximately 60 million to 200 million.Gas is the unit that measures how much computational workload a single block can accommodate on Ethereum. A higher limit means the network can handle more transactions and more complex activities simultaneously, but it also places higher demands on the computers running Ethereum. Prysm is the client software used by Ethereum validators, and its previous version had completed before this setting was added to the Sepolia configuration. Therefore, validators running the old version will still produce blocks with a 60 million Gas limit unless they manually modify the parameters, which undermines the effectiveness of this capacity test.Validators running the latest version will automatically start proposing blocks with a 200 million Gas limit when Glamsterdam activates on Sepolia at 13:53:36 UTC on October 6. Ethereum has been gradually increasing block capacity to test how far it can go before running validators becomes too demanding or expensive. The 200 million setting is only applicable to Sepolia, and Glamsterdam has not yet been activated on the Ethereum mainnet.

The Ethereum staking withdrawal queue has retreated from last week's peak. After MetaMask began withdrawing validators, the withdrawal queue once climbed to about 851,000 ETH, and is currently down to about 767,000 ETH. Previously, on September 29, the queue was only about 166,000 ETH, growing more than five times in just a few days, reaching about 2% of the total staked ETH of approximately 43.6 million.On September 30, MetaMask disclosed a security incident affecting some of its infrastructure and took the affected validators offline as a precaution. Its update on October 1 stated that the investigation found no signs of impact on wallets or customer funds. In addition to its wallet services, MetaMask also operates validators for the staking service provider Lido. Ethereum security researcher Kaden estimates that this precautionary withdrawal involves about 17,000 validators and approximately 523,000 ETH, although MetaMask has not confirmed this data.Lido expects that as the affected validators withdraw and their balances are extracted, these ETH will gradually be restaked, a process that may take about 45 days. During the downtime, the affected validators will miss out on rewards, and Lido stated that stETH holders do not need to take any action. Meanwhile, the demand for entering the staking queue has cooled, with about 1.5 million ETH waiting to enter, and the estimated waiting time is about 25 days.

Linea's official statement indicates that some validators supporting the Yield Boost treasury are withdrawing as a precaution due to the MetaMask staking incident. Linea emphasizes that the funds and control of the staking treasury itself have not been affected.The impact of this incident is that during the period when relevant validators withdraw and are replaced by new validators, the net staking rewards that provide funding sources for ecosystem incentives will temporarily decrease. Linea stated that it is closely monitoring the situation's progress.

MetaMask has released a follow-up statement regarding the previously disclosed infrastructure security incidents, stating that the team is continuously conducting investigations and addressing the issues.MetaMask stated that to ensure user safety, it has collaborated with relevant partners to take preventive measures and is currently withdrawing the affected validator nodes from its non-custodial staking business. According to the investigation results so far, there is no indication that MetaMask wallets or customer funds have been affected.This morning, part of the infrastructure of MetaMask's non-custodial staking business encountered a security incident. As a precaution, the validators operating on Lido have begun to withdraw.

The decentralized trading protocol Osmosis in the Cosmos ecosystem announced that the maintenance mode of the past few months is coming to an end, and active development will resume. The team stated that the first step is to streamline the core product, including simplifying the tokenomics, focusing on the treasury, and enabling the network to act faster when needed.Osmosis proposed three adjustments to OSMO, all of which will be submitted for on-chain governance. First, further reduce inflation, decrease the circulation of new OSMO, and stop injecting newly minted OSMO into the community pool, making the network rely more on actual revenue. Second, destroy most of the OSMO held by the community pool, as well as the OSMO previously allocated from the community pool. Third, the treasury will only provide liquidity for the core liquidity pool, with a complete list to be published before the changes take effect.The team also plans to reduce the active validator set to 30, stating that a smaller set helps with security incident response and chain upgrade coordination, and aligns with a low-inflation model. Osmosis stated that streamlining the protocol is to prepare for future expansion, as it remains the central venue for IBC asset trading, and seeks community input on the direction of the next steps.

The liquidity staking protocol Lido announced that MetaMask Staking (formerly Consensys Staking) has taken precautionary measures to protect customer assets related to its Ethereum validators after investigating an infrastructure breach incident. The related measures include withdrawing its Ethereum validators from the Lido protocol, which may result in some loss of rewards. If the validators go offline recently to reduce potential network slashing risks, it may also incur downtime penalties.Lido stated that the related validators have begun to withdraw, with the last batch expected to complete the withdrawal by October 7, 2026, but full withdrawals may not be completed by then. stETH holders do not need to take any action. The ETH withdrawn from the validators operated by MetaMask Staking is expected to gradually return to the protocol during the cycle of the validators completing the withdrawal, withdrawing, and re-entering, with the estimated maximum duration of this process being about 45 days due to extended queuing times.Lido reminds that staking operations are non-custodial, and MetaMask does not manage withdrawal keys on behalf of customers. The diversified node operators of the Lido protocol and other security mechanisms, including a temporary reserve of over 6,750 stETH, are designed to control and mitigate disruptions to the normal operation of the protocol. A comprehensive investigation is ongoing, and further updates will be announced separately.
