According to official news, the prediction market Polymarket announced a significant adjustment to its settlement mechanism for cryptocurrency price fluctuation markets starting from August 7, to protect market integrity. From midnight UTC on that day, the affected markets will no longer settle based on a single price snapshot at a specific time but will instead use a time-weighted average price.Markets of different durations correspond to different TWAP windows: all cryptocurrency 5-minute markets will use a 30-second TWAP, 15-minute markets will use a 60-second TWAP, and 4-hour markets will also use a 60-second TWAP. The previous single snapshot settlement method was prone to price manipulation during periods of low liquidity, and this change is a proactive reinforcement of the market integrity system by Polymarket after facing regulatory scrutiny.To support this transition, Polymarket will inject $1 million in liquidity rewards into all affected markets throughout August. On the technical side, Chainlink TWAP testnet data streams are now available, and mainnet data streams along with Polymarket real-time data stream services will go live on August 4, at which point developers can access TWAP prices directly through Chainlink Data Streams or Polymarket's public WebSocket.

According to official news, Websea has completed a major upgrade of the contract insurance airdrop rules on July 30, 2026.

According to VentureBeat, the Model Context Protocol (MCP) has received its largest update since its launch in November 2024, managed by the Agentic AI Foundation (AAIF) under the Linux Foundation. This update completes the transition to a fully stateless architecture, allowing MCP servers to be deployed behind standard load balancers without relying on "sticky routing" or shared session state, thereby simplifying large-scale cloud-native and Kubernetes deployments.In terms of security, the new version of MCP enforces validation of the issuer (iss) parameter for OAuth and OpenID Connect to prevent mix-up attacks and introduces enterprise-hosted authorization extensions to support unified identity governance for enterprises. The protocol also establishes a formal deprecation policy, ensuring that features are announced for deprecation at least 12 months before their earliest removal. MCP Apps and MCP Tasks have also been upgraded to official extensions, supporting servers in providing interactive interfaces to AI clients and executing interruptible, resumable long-running asynchronous tasks through persistent task handles. According to MCP co-creator David Soria Parra, the related SDK's weekly download volume has reached approximately 250 million, doubling in the past six months.

Zcash activated the Ironwood NU6.3 network upgrade at block height 3,428,143, launching a new shielded pool to enhance network security and allow for the independent verification of ZEC circulating supply.After the upgrade, the original Orchard pool was restricted, and new funds are not allowed to enter. Existing funds must be migrated out through a turnstile before re-entering Ironwood, ensuring at the protocol level that pool expenditures do not exceed verifiable income. Ironwood is based on a revised protocol that has been formally verified and independently audited, aimed at preventing similar risks to the previous Orchard declarative vulnerabilities. Wallets supporting Ironwood (such as Zodl 3.8.0) have provided migration paths, allowing users to transfer funds from Orchard to the new pool without changing addresses.

Coinbase posted on the X platform that it is upgrading the Coinbase DEX experience, allowing users to immediately find and trade after Base or Solana tokens go live on the chain, now available in the new Launches tab.

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.

The Ethereum staking protocol Lido stated on platform X that the stETH Rebase has been completed as expected, and the missed ETH earnings due to insufficient calculations have been compensated, corresponding to an annual percentage rate (APR) of approximately 2.29%. At the same time, the protocol's oracle has been updated and passed the audit, with the new version improving report processing speed and helping to quickly identify the cause of similar issues in the future.Regarding the abnormal earnings calculation that occurred, Lido stated that contributors are currently conducting a root cause analysis, and more investigation details will be announced on the official forum and social media platforms. Throughout the entire incident, user funds have not faced any risk. The preliminary judgment is that the issue may stem from a special edge case: a validator in a pending deposit state was omitted from the earnings report, resulting in some staking earnings not being included in the calculations. Lido stated that a complete post-mortem report will be released in the coming days to further explain the cause of the issue, corrective measures, and subsequent improvement plans.

Zcash core developer Sean Bowe posted on the X platform that the block height for the Zcash Ironwood mainnet activation has been determined and marked. All major organizations have committed to activating the NU6.3 upgrade at block height 3,428,143, expected to occur at 8 PM Beijing time on July 28.According to previous news, this upgrade stems from the earlier Orchard pool vulnerability—this vulnerability could allow attackers to mint an unlimited amount of counterfeit ZEC, and due to the privacy attributes of the Orchard pool, the team could not determine whether any counterfeit ZEC was minted before the vulnerability was patched. The Ironwood upgrade will implement two core measures: first, it will introduce a new privacy pool using the Orchard protocol, while the old pool will be gradually phased out; second, it will add a control flag in the zero-knowledge proof circuit, which, when enabled, can disable the function of transferring to other users in the pool while retaining the change feature.
