fork

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.

Bitcoin News posted on the X platform that Dathon Pwn claims to have discovered a BIP 110 late upgrade consensus vulnerability, which may allow nodes upgrading from old software to retain chain history, while newly deployed BIP 110 nodes would reject this history, potentially leading to a hidden chain split.

The Bitcoin mining pool OCEAN announced on platform X that the backend of OCEAN will be upgraded to independently follow multiple chains in the event of a BIP 110 chain fork.If a fork occurs, DATUM miners will automatically continue to operate on the chain executed by their nodes, and OCEAN will record the rewards of that chain in the fork share log based on the ongoing operation and service terms of that chain. OCEAN will effectively operate as two mining pools from the fork point, and the updated service terms will be published before block 961,632.

According to FinanceFeeds, Ethereum developers are evaluating the EIP-8182 proposal, which aims to introduce native privacy transfers for ETH and ERC-20 tokens through the Hegotá hard fork. The proposal was created by Facet co-founder Tom Lehman on March 3, 2026, and belongs to the Draft Standards Track Core EIP, which has not yet been finalized or scheduled for inclusion in the upgrade.Hegotá is the next upgrade following Glamsterdam, expected to focus on infrastructure and protocol layer improvements. The core of EIP-8182 is to create a standardized shielded pool system contract at the protocol layer, where users can deposit ETH or ERC-20 tokens and use zero-knowledge proofs to spend the tokens. The system adopts a UTXO model instead of Ethereum's account balance model, using a separate proof architecture that does not rely on an administrator-controlled upgrade mechanism or pause functionality.The proposal aims to address issues faced by application layer privacy tools, such as small anonymity sets and governance risks. If included in Hegotá, it would be one of the most significant privacy upgrades for Ethereum. Core developers still need to assess its cryptographic assumptions, state growth, denial-of-service risks, and whether it will be included remains undetermined.

The official announcement from the Zcash (ZEC) Foundation states that independent security researcher Taylor Hornby discovered a serious reliability vulnerability in the Orchard zero-knowledge proof circuit on May 29, which could allow double spending within the Orchard pool.Core engineers from ZODL confirmed the issue within hours and initiated a fix. To buy time, they temporarily disabled Orchard operations through an emergency soft fork of Zebra 4.5.3 in the early hours of June 2. Finally, today, they activated the NU6.2 hard fork through Zebra 5.0 — at 12:05 PM Beijing time, the mainnet successfully completed the upgrade at block height 3,364,600, re-enabling Orchard with the corrected circuit, and the vulnerability was permanently closed.This is the second time Zcash has triggered a protocol upgrade due to security issues since its launch in 2016, with no known exploits occurring during the process. The network's total supply guard mechanism confirmed that the total supply remained intact, and user privacy, as well as Sapling and transparent transactions, were not affected.

According to the official announcement, Binance is expected to suspend token deposits and withdrawals on the Base network on May 29, 2026, at 01:00 to support its network upgrade and hard fork. Token trading on the aforementioned network will not be affected. The project team expects to carry out the network upgrade and hard fork on May 29, 2026, at 02:00.

According to the official announcement, Binance is expected to suspend token deposits and withdrawals on the Base network on May 22, 2026, at 01:00 (UTC+8) to support its network upgrade and hard fork. The project team expects to carry out the network upgrade and hard fork on May 22, 2026, at 02:00 (UTC+8).

Binance will support the RIF network upgrade and hard fork. Starting around May 4, 2026, at 17:00, Binance will suspend token deposits and withdrawals on the Rootstock Infrastructure Framework (RIF) network.The network upgrade and hard fork will take place at block height 8,804,200, or approximately at 18:00 on May 4, 2026. Once the upgraded network is stable, the token deposit and withdrawal functions on the aforementioned network will be reopened.

According to CoinDesk, Paul Sztorc, a developer who has long focused on Bitcoin scaling solutions, proposed a Bitcoin hard fork named eCash to be initiated in August 2026 at block height 964,000, distributing eCash to users holding BTC at a 1:1 ratio at the time of the fork, and introducing a Drivechains sidechain architecture in the new chain.The controversy mainly revolves around the plan to pre-allocate a portion of eCash corresponding to Satoshi Nakamoto's address on the new chain to early investors, a move that has drawn criticism from the community, with some individuals claiming it involves "stealing" tokens. Paul Sztorc stated that this move aims to provide incentives for development and collaboration before the project's launch.

Minh Don, the product lead of Drift, stated on its official Discord that it will take a few weeks to optimize the codebase, remove and add some small but impactful features, and plans to relaunch its forked exchange in May or June this year.Previously, Drift Protocol suffered losses exceeding $285 million in an attack incident.

Bitcoin developer Paul Sztorc announced the official launch of the Bitcoin hard fork network eCash, allowing BTC holders to exchange BTC for eCash at a 1:1 ratio after the hard fork goes live.It is reported that the Layer1 node software of this network will be an "almost replica" of the Bitcoin Core client, continuing to use the SHA-256 hashing algorithm and lowering the initial mining difficulty to attract more miners to participate. Meanwhile, eCash will also be equipped with seven Layer2 scaling networks called "drivechains" to enhance transaction throughput and support optional on-chain privacy features. Paul Sztorc stated that eCash is different from Bitcoin Cash in 2017, no longer using the "Bitcoin" name, and claims it is a long-term solution to Bitcoin's scalability and privacy issues. However, the proposal to manually reallocate a portion of Satoshi Nakamoto's approximately 1.1 million BTC to early investors has sparked strong controversy in the community, with some Bitcoin supporters criticizing the move as "theft" and a violation of Bitcoin principles.

Charles Hoskinson, the founder of Cardano, stated that Bitcoin's quantum defense proposal BIP-361 has been mischaracterized as a soft fork, and is actually closer to a hard fork, and it cannot protect approximately 1.7 million early BTC generated before 2013, including about 1 million bitcoins attributed to Satoshi Nakamoto.He mentioned that the zero-knowledge proof recovery scheme in the proposal relies on BIP-39 mnemonic phrases, while early wallets used different key generation methods that cannot provide the required proof, thus the relevant assets may be permanently frozen under the current scheme. Reports also indicated that BIP-361 co-author Jameson Lopp described it as a rough concept for an emergency plan, rather than a final specification.

Farcaster posted, "There will be no token issuance. The 'token discussion' circulating in the market is actually related to Hypersnap, which is a fork project of the Farcaster protocol. The Hypersnap team refers to its token as the 'Farcaster token' in discussions, which has led to confusion among users who are not familiar with the technical details.It is important to clarify that this is not a comment on the fork project itself. We just want to avoid this kind of speculation that continues to create unnecessary noise, such as bot accounts, airdrop users, and scam accounts, all of which can affect the overall network experience. It should be made clear that there is no so-called Farcaster protocol token airdrop."

According to the official announcement, Binance is expected to suspend token deposits and withdrawals for the Polygon (POL) network on April 8, 2026, at 21:00 (UTC+8) to support its network upgrade and hard fork.The project team will carry out the network upgrade and hard fork at block height 85,268,500 (expected on April 8, 2026, at 22:00 UTC+8).

The founder of Slow Fog, Yu Xian, posted on the X platform: "I don't trust the stability or resilience of OpenClaw, but I am quite confident in Claude Code, as this is one of the core goals of software engineering. In terms of security emphasis, both companies place a high priority on security, and submitted vulnerabilities receive timely feedback. Some OpenClaw forks or reference versions show much less enthusiasm for security.In terms of security scenarios, although OpenClaw also has a Sandbox mechanism and attempts to design more granular permissions for tools, as its name 'OpenClaw' suggests, 'Open' is its greatest charm. A constrained OpenClaw is no longer OpenClaw. We hope for it to be free while also wanting it to be controllable, which is a point of contention for everyone. However, in a real production environment, an overly free OpenClaw can easily get out of control."

According to the official announcement, Binance is expected to suspend the token deposit and withdrawal services for Polygon (POL) on March 4, 2026, at 21:00 (UTC+8) to support its network upgrade and hard fork.The project team will conduct the network upgrade and hard fork at block height 83,756,500 (expected on March 4, 2026, at 22:00 UTC+8).

The former CEO of the collapsed exchange Mt. Gox, Mark Karpelès, recently proposed a Bitcoin hard fork plan, suggesting to modify the consensus rules to recover approximately 79,956 BTC stolen in the 2011 hacking incident, which is valued at about 5.2 billion dollars at current prices.The proposal targets a wallet address associated with the 2011 Mt. Gox system breach, which received nearly 80,000 bitcoins after the hack and has remained unused for over 15 years. Currently, under existing Bitcoin rules, these funds can only be transferred if the corresponding private key is held. According to the proposal, the new rules would allow the unspent outputs in that address to be controlled through signatures from the Mt. Gox recovery address, thereby incorporating the funds into the existing judicial oversight compensation process for repaying Mt. Gox creditors.Karpelès stated that the plan is merely a starting point for discussion, intending to limit the rule modification to a single address and activate it at a specific block height in the future. However, the proposal also acknowledges that this plan requires coordinated upgrades across the entire network, and if some community members refuse to support it, it could lead to the risk of a blockchain split. It is important to note that these approximately 80,000 BTC are currently not part of the assets allocated to Mt. Gox creditors and are not under the control of the bankruptcy trustee.

Ethereum Foundation researcher Justin Drake announced that the Ethereum Foundation has launched the "strawmap" roadmap, planning seven forks by the end of 2029.The roadmap includes five objectives: fast L1 finality, a "gigagas" L1 achieving 10k TPS through zkEVM, a "teragas" L2 enabled by data availability sampling, post-quantum cryptography, and native L1 privacy for shielding ETH transfers.
