fork

BNB Smart Chain (BSC) announced that the Pasteur hard fork will officially launch on the mainnet at 10:30 AM Beijing time on August 25 (02:30 UTC on August 25). Node operators need to upgrade to client version v1.7.7 in advance. This upgrade includes three improvements: BEP-682, BEP-695, and BEP-675, focusing on enhancing cross-chain security, validator governance mechanisms, and network throughput capacity.Among them, BEP-682 will strengthen the cross-chain bridge validation mechanism of the BNB Chain, preventing the risk of permission bypass caused by duplicate calculations of validator signatures, thus improving the security of cross-chain asset transfers. BEP-695 optimizes the validator key rotation mechanism, ensuring that old keys no longer retain management permissions after exiting, while also fixing potential vulnerabilities related to penalties and governance voting. In terms of performance, BEP-675 reduces the time consumption caused by validators repeatedly executing transactions by optimizing the block construction process.In the internal QANet testing environment of the BNB Chain, this solution increased throughput from 1237 TPS to 2324 TPS, while maintaining a block time of 450 milliseconds and a block limit of 100 million Gas, with the average Gas usage per block rising from 46.35 million to 84.15 million.BNB Chain stated that this upgrade is primarily aimed at validators and block builders, intending to provide greater capacity during network peak periods and to promote the throughput expansion goals outlined in the BNB Chain roadmap for the second half of 2026.

Conflux Network announced that the v3.1.0 network hard fork upgrade will introduce multiple network improvements, including EVM compatibility updates, bug fixes, RPC changes, and security enhancements. CIP-173 is expected to be activated on August 26.

BIP-110 received only about 2.5% miner hash power support when the activation deadline was reached and failed to activate. The nodes executing the proposal forked from the mainnet at block height 961632, and a minority chain subsequently stopped producing blocks.Bitcoin Mechanic, a supporter of BIP-110, stated that this outcome proves Bitcoin has encountered "protocol capture," where large mining pool operators coordinate to influence consensus rules and undermine node sovereignty. Since the minority chain received less than 3% of the total network hash power, its inherited mining difficulty led to a halt in block production. Some supporters are considering changing the PoW algorithm through a hard fork, and Bitcoin Mechanic indicated that they would wait to resume node operations after the Bitcoin Knots update.Cysic founder and CEO Leo Fan stated that the difficulty adjustment mechanism protects the main chain, and the mandatory activation design of BIP-110 is the main issue. The anonymous owner of 1win pointed out that the proposal only received 2.53% support, below the 55% activation threshold, and the main chain is still continuously operating.

The proposed soft fork BIP-54 (Consensus Cleanup) specification for Bitcoin was completed in May 2026, aimed at fixing four consensus rule boundary issues without adding new Bitcoin features. Wang Chun, co-founder of the digital asset mining pool F2pool, stated that they do not support BIP-54 and mentioned that if the proposal obtains the required majority through the standard BIP-9 process, F2pool will upgrade its mining nodes but will not issue a support signal in advance.BIP-54 has been tested in the Signet-based testing environment Bitcoin Inquisition, and the mining pools MARA and ViaBTC have voluntarily produced compatible coinbase transactions; the formal activation parameters have not yet been determined, and the mainnet voting is still incomplete. Previously, BIP-110, which attempted to restrict certain non-financial data in Bitcoin transactions, did not receive enough support from miners and stalled around block height 961635; BIP-54 does not involve restricting general script functionality.

Luke Dashjr has randomly determined that BLAKE2b will be the new POW algorithm for the BIP-110 chain, expected to replace the currently used SHA-256d algorithm in Bitcoin. Compared to SHA-256d, BLAKE2b is more suitable for mining with general-purpose CPUs/GPUs, being more CPU-friendly, which can reduce the advantages of existing Bitcoin ASIC miners.Previously, it was reported that Luke Dashjr plans to officially implement the BIP-110 hard fork on September 1, making it an independent blockchain and generating a new token distinct from Bitcoin. Luke Dashjr has had his Bitcoin BIP editing permissions revoked by the Bitcoin BIP editing team.

BIP-110 soft fork has stalled due to support rates far below standard, with thousands of nodes isolated. Just two days after the incident, the Bitcoin BIP editing team removed the editing privileges of the proposal leader Luke Dashjr on Monday. Editor Mark Erhardt proposed a motion for dismissal, citing reasons including conflicts of interest, minimal contributions, leading a controversial fork, and coordination breakdown.Supporters pointed out that Dashjr used his editing privileges to favor the BIP-110 proposal, assigning numbers and quickly merging PRs before discussions on the mailing list, and has contributed less than 1% since April 2024. The peak signal support for BIP-110 was only 2.53%, far from the 55% threshold, and the forced chain has stalled at a height of 961,633. Ocean was the only mining pool signaling before the fork, and has now resumed non-BIP-110 work. Dashjr announced the suspension of his roles as Chairman and CTO of Ocean four minutes before the dismissal confirmation, shifting to Bitcoin open-source projects, but still serves as the chief maintainer of Bitcoin Knots. The price of Bitcoin was unaffected by the incident.

Bitcoin News posted on the X platform that Luke Dashjr stated that the developer meeting is "progressing smoothly," and related plans are being advanced, aiming to change Bitcoin's proof-of-work algorithm through a hard fork.The developers are expected to announce the selected hash algorithm tomorrow and enable RTDS starting from the first block. Discussions are also underway regarding block size reduction and replay protection. At the time of this announcement, reports indicated that Dashjr is no longer a licensed user of the BIP content repository. If this proposal is implemented, the change in the proof-of-work algorithm will create an independent blockchain and essentially form a new altcoin, with existing BTC holders receiving tokens on the forked chain.

The Bitcoin minority fork supporting BIP-110 split at block height 961,632, and after mining only 2 blocks in about 8 hours, it has stagnated, now lagging behind the Bitcoin mainnet by over 80 blocks.This fork inherits the current difficulty of Bitcoin, but only about 2.53% of recent block signals support BIP-110, far below the 55% activation threshold required without a fork. Bitcoin adjusts its difficulty only after mining 2016 blocks, and based on the current hash rate, this chain is expected to take about 350 days to complete its next adjustment.BIP-110 aims to temporarily prohibit writing non-financial data such as images and text in Bitcoin transactions. Michael Saylor stated that about 99.85% of Bitcoin hash power remains on the mainnet; due to both chains being affected by the same transactions, transactions on the minority chain may be replayed to the Bitcoin mainnet.

Strategy founder Michael Saylor posted that Bitcoin's operation fully aligns with its design. BIP-110 can fork freely, and the Bitcoin network can also choose not to follow. As a result, about 99.85% of Bitcoin's hash power remains on the original network, while the BIP-110 branch has only mined 2 blocks and is currently over 80 blocks behind.He pointed out that BIP-110 has only gained about 0.15% of Bitcoin's hash power and needs to mine 2015 blocks before the first difficulty adjustment. Based on the current block generation speed, this process will take about 25 years.Saylor stated: "Anyone can fork Bitcoin, but if there is a lack of security, practicality, capital, and users, the fork is meaningless. Consensus needs to be earned, not declared."

ECX developer Paul Sztorc announced that the ECX hard fork will be launched in three phases, rather than the originally scheduled single release on August 23. ECX is a new blockchain that replicates the complete transaction history of Bitcoin at a specified block height. Almost all Bitcoin holders, except for Satoshi Nakamoto's portion of Bitcoin, will receive an equivalent amount of ECX, and the Bitcoin network itself will not change.The first Alpha version will be activated on August 23 at block height 963648, the Beta version will go live on September 20 at block height 967680, and the permanent complete version is scheduled for release on October 31 at block height 973728. Tokens collected during the Alpha and Beta phases can be destroyed and exchanged for official ECX once the permanent chain is launched. The replay protection for ECX remains an optional mechanism; the official wallet will enable this protection and remind users before executing transactions. Paul Sztorc stated that if users ignore the reminder, ECX will replay their Bitcoin transactions, causing the related Bitcoins to follow the user out and transfer to new holders; October 31 also marks the 18th anniversary of Satoshi Nakamoto's publication of the Bitcoin white paper.

Bitcoin developer Kevin Loaec warned that if a Bitcoin fork related to the controversial proposal BIP-110 occurs this weekend, holders may face the risk of real BTC being transferred when selling forked chain tokens.The proposed Bitcoin fork is associated with the controversial BIP-110 proposal and may generate duplicate balances on two chains, leading holders to attempt to sell seemingly free forked coins.Since both chains initially accept the same transactions, selling forked coins could trigger a replay attack, simultaneously spending real Bitcoin from the seller's main chain. Developers stated that there is a lack of built-in replay protection at least until early September, and non-professional users should avoid transferring Bitcoin during the potential fork.

The Ethereum Foundation has released a job posting for a Protocol Security Researcher, part of the protocol security team, responsible for identifying security vulnerabilities in various aspects such as the execution layer, consensus layer, network layer, specifications, and client implementations. The work includes AI-assisted security research and automated vulnerability discovery, hard fork reviews, fuzz testing tool development, manual audits of protocol changes, and coordinating vulnerability disclosures.The team requires candidates to have deep experience with the Ethereum protocol, with a preference for engineers who have actively participated in protocol development and are familiar with the specifications of the execution layer or consensus layer. Common programming languages include Go, Rust, Java, C#, Nim, and Python. Remote work is available, and the position is open to candidates in Europe and globally.

According to Bitcoin Magazine, the BIP-110 soft fork is about to enter a critical activation phase. The proposal will enter the mandatory signaling phase around August 9, corresponding to block height 961,632, and is expected to lock in at block 963,648 by the end of August, with new transaction rules activated at block 965,664 in early September. BIP-110 adopts a 55% signaling threshold, and its restrictions will be enforced for 52,416 blocks (approximately one year).BIP-110 mainly restricts transaction features such as large data pushes, oversized output scripts, undefined witness versions, and Taproot annexes, but exempts UTXOs created before activation, maintaining compatibility for standard currency use. Analysis indicates that most businesses do not need to take action—businesses that act as value storage or process transactions through third-party payment providers are essentially unaffected. Businesses running their own full nodes can choose whether to switch to BIP-110 nodes. The core risk to be aware of is chain forking. If a fork occurs, miners should choose the branch expected to prevail or pause and wait; exchanges and custodians should increase confirmation requirements, monitor dual chains, and delay final settlements to prevent double spending and false confirmation risks. If there is no fork, no special actions are required.

Binance announced that it will support the BNB Smart Chain (BEP20) network upgrade and hard fork.To accommodate this arrangement, the platform will suspend deposits and withdrawals for this network starting from July 30, 2026, at 05:55 (UTC), and wallet maintenance will begin at 06:00 (UTC), expected to last for about 1 hour.

Renowned analyst PlanB expressed opposition to the Bitcoin BIP-110 proposal, believing that those supporting the fork do not truly understand the decentralized nature of Bitcoin.The proposal aims to temporarily limit non-payment data on-chain through a soft fork, with the current miner support rate at approximately 1%.

The Polygon Foundation posted on the X platform that the Ithaca hard fork has been successfully deployed on the Amoy testnet and will go live on the Polygon mainnet at block height 50,185,000 (expected at 22:00 Beijing time on July 29).This upgrade aims to enhance payment reliability: automatic failover during rare stalls of block producers ensures smooth transactions, new protective mechanisms intercept transactions that may cause the network to slow down or become unstable, while providing node operators with clearer visibility to ensure seamless integration of underlying operations. All node operators are required to upgrade as soon as possible to ensure compatibility and network security.

According to CoinDesk, the Cardano mainnet completed the "Van Rossem" hard fork on July 18, upgrading the protocol version to 11, primarily reducing the cost of smart contract execution and paving the way for subsequent scaling solutions.This upgrade was the first to be fully proposed, discussed, and voted on by the community through the on-chain governance process, rather than being directly led by the founding development company Input Output. On-chain data shows that the voting support rate was approximately 78.97%, all 7 members of the Constitutional Committee confirmed that the proposal complied with the "Cardano Constitution," about 53.02% of node operators voted in favor, and over approximately 93% of block production pledges have run the new version of the node.This upgrade prepares technically and procedurally for the scaling solution Ouroboros Leios, which is planned to go live in 2026.

On July 18, 2026, at 21:44:51 UTC, Cardano activated the Van Rossem hard fork, upgrading the network to protocol version 11, with no reported downtime. This upgrade is part of the changes within the Conway ledger era, aimed at reducing the operating costs of Plutus smart contracts, enhancing ledger security, and introducing new cryptographic tools.Van Rossem includes 5 Cardano Improvement Proposals, involving BLS12-381 multi-scalar multiplication, on-chain array types, optimization of multi-asset value processing, acceleration of list operations, and built-in modular exponentiation. Staking pools are now prohibited from reusing the same verifiable random function key across the entire network; each pool must hold a unique key bound to its identity.This upgrade was completed through the Cardano on-chain governance process, with the proposal to activation advanced by on-chain voting. Delegated representatives passed the proposal with a support rate of 77.63%, while the support rate among staking pool operators was 52.7%, and the constitutional committee's voting result was 6-0-0-1. Wallets holding between 100,000 and 100 million ADA saw their total balance rise to the highest level since 2023, currently controlling over a quarter of the circulating supply of ADA. Cardano will subsequently advance Ouroboros Leios and plans to achieve a target of over 1,000 transactions per second during the testing period in 2026.
