According to The Block, the Ethereum Foundation Protocol Cluster has released a list of EIP ratings for the upcoming Hegotá upgrade, setting December 2029 as the target milestone for achieving full quantum resistance. The two S-tier (mandatory delivery) proposals for the upgrade are: FOCIL (EIP-7805) at the consensus layer, which enhances censorship resistance by requiring validator committees to enforce the inclusion of public mempool transactions; and framework transactions (EIP-8141) at the execution layer, which natively integrates account abstraction, supporting custom signatures, sponsored gas, and batch operations to improve security and quantum resistance. The Ethereum Foundation stated that this timeline aligns with the independent migration targets of Google, Cloudflare, and Microsoft, and the December 2029 deadline will be considered non-negotiable prior to January 2027. Hegotá is not the final quantum-safe fork, but rather a critical milestone determining whether subsequent upgrades can proceed on schedule. From the Q4 2026 Glamsterdam upgrade to December 2029, the average fork cycle is only about 7.2 months, leaving extremely limited execution slack.
Odaily News: The sandwich attack bot operated by JaredfromSubway.eth has extracted a cumulative total of 117,007 ETH since March 2023, worth approximately $295 million at current prices. In June 2026, an anonymous attacker deployed 66 counterfeit token contracts, exploiting the bot's automated trading logic to steal at least $7.5 million in ETH and stablecoins, and funneled the funds into Tornado Cash. The stolen assets have not yet been recovered.Sandwich attacks are a form of Maximal Extractable Value (MEV): the bot monitors large transactions in Ethereum's public mempool, buys ahead of the target transaction, and sells after the transaction pushes the price up, capturing profits from the spread. The bot's primary contract had received a cumulative total of 117,007 ETH as of August 28.MEV-Boost block construction is centralized among a small group of participants, with relay.ultrasound.money, Titan Relay, and bloXroute regulated relays collectively forwarding approximately 85% to 88% of related blocks within a 24-hour window; Titan's builder independently assembled 50.3% of the blocks. Monthly sandwich attack extraction amounts have declined from approximately $10 million in late 2024 to roughly $2.5 million in October 2025. (Bitcoin.com News)
: Blockchain technology company Starkware stated that on August 26, a transaction using researcher Avihu Levy's Quantum-Safe Bitcoin (QSB) scheme was mined on the Bitcoin mainnet, without requiring a soft fork, hard fork, or modification of consensus rules.The transaction consumed 10,000 sats and was processed through MARA Foundation's Slipstream service, as the non-standard format typically cannot propagate through Bitcoin's public mempool. The test consumed several hours of GPU computation, costing approximately $150 to $200.QSB employs hash-based quantum-resistant spending conditions and reduces quantum attack risks through signature trial mining, but still requires users to proactively migrate funds and cannot protect assets whose public keys have already been exposed. Starkware CEO Eli Ben-Sasson still supports introducing a protocol-level solution via a soft fork. (Bitcoin.com News)
According to The Block, StarkWare announced it has successfully executed the first post-quantum Bitcoin transaction. Avihu Levy, Head of Applications, used a "signature grinding" approach to repeatedly generate millions of candidate signatures before the transaction entered the Bitcoin mempool, thereby avoiding the exposure of mathematical data related to public keys that could be exploited by future quantum computers to forge signatures. This method incurs significant computational costs, with a single transaction potentially taking several hours. Because the transaction format is unrecognized by standard Bitcoin nodes, it bypassed the public mempool and was submitted directly to miners for inclusion via MARA’s Slipstream service. StarkWare noted that while this technique can serve as a transitional safeguard, Bitcoin will still require protocol-level upgrades or a hard fork to systematically mitigate quantum computing threats.
Odaily News: Bitcoin wallet service provider Nunchuk has issued an important update regarding the recent Coldcard security incident, recommending that users with multisig wallets containing Coldcard-generated keys migrate their funds as soon as possible.Nunchuk has categorized response levels based on the number of affected Coldcard keys in a multisig wallet: if the number of Coldcard-generated keys has reached the signing threshold, attackers could theoretically transfer funds directly, and such users should migrate immediately; if the wallet contains only 1 Coldcard-generated key and it is below the signing threshold, a single compromised key cannot move funds independently, making the risk relatively lower, but migration is still strongly recommended. If users cannot confirm the exact number of Coldcard keys in their wallet, they should treat it as a high-risk situation.Additionally, Nunchuk announced that an upcoming mobile update will automatically enable the Slipstream channel for paid users. At that point, any auxiliary multisig wallet transaction containing at least one Coldcard key will bypass the public mempool and be submitted via Slipstream, reducing the risk of transaction monitoring and replacement. For users who wish to act immediately or for free-tier users, Nunchuk offers a manual migration option: users need to create a migration transaction, complete multisig signing without broadcasting, and then submit the raw transaction data to the Slipstream platform.
Odaily News, March 24 – Antpool mined Bitcoin block 941,881 at UTC time 15:49:35. Foundry USA mined another version of the same height 12 seconds later, briefly creating two competing chains on the Bitcoin blockchain. Subsequently, ViaBTC extended block 941,882 on top of the Antpool version, while Foundry USA also continued to extend its own branch. Foundry USA then mined blocks 941,883 to 941,886 consecutively, giving its branch a cumulative workload lead. Nodes subsequently reorganized to the Foundry USA version, causing the blocks mined by Antpool and ViaBTC to become orphaned. The affected miners lost the corresponding block rewards and fees, and transactions not confirmed on the winning chain re-entered the mempool to be confirmed in subsequent blocks.
According to The Block, BNB Chain is building a new Layer 1 blockchain designed specifically for agent trading, targeting transaction pre-confirmation in under 50 milliseconds, and suppressing MEV behaviors such as sandwich attacks by eliminating the public mempool (adopting the TxStream mechanism). The new chain will also reserve block space for oracles, liquidations, and cross-chain bridges via PriorityLane, with a designed throughput target exceeding 100,000 TPS, and supporting sub-second block finality. This chain will become the fourth chain in the BNB Chain ecosystem, connected to BNB Smart Chain via a native bridge, with BSC serving as the settlement hub. The testnet is planned to launch at the end of 2026, and the mainnet is expected to deploy in early 2027.
BNB Chain is developing a new Layer 1 blockchain designed for Agentic Trading, releasing the first detailed architectural information after months of research and development. According to BNB Chain's disclosed technical roadmap for the second half of 2026, the new chain will run in parallel with the existing BNB Chain ecosystem, targeting transaction preconfirmation times of less than 50 milliseconds. The goal is to deliver an execution experience close to that of centralized exchanges (CEX) while retaining the advantages of on-chain self-custody and transparency.In terms of technical architecture, the new chain will remove the traditional public mempool and introduce a transaction transmission mechanism called "TxStream," which directly sends transactions to block producers to reduce latency and minimize MEV extraction behaviors such as sandwich attacks.

: The Zcash Foundation has released version 4.5.0 of its node client, Zebra. This update includes multiple security fixes, addressing a critical consensus vulnerability and several high-severity Denial of Service (DoS) issues. All node operators are strongly urged to upgrade immediately.Key fixes in this release include a sigop counting error in P2SH script parsing (which could cause a consensus fork with zcashd), a logic flaw in NU5 block validation caching, a crash risk related to transparent address balance overflow, along with multiple crash and resource exhaustion vulnerabilities in RPC interfaces and mempool processing. The Foundation stated that some vulnerabilities could be exploited by malicious nodes, leading to node stalls, restart loops, or even permanent stoppage.Additionally, this version adds support for ZIP-213 (enabling shielded coinbase outputs to Sapling) and optimizes network performance and security boundaries. This includes limiting resource allocation during the pre-handshake phase, fixing risks related to multi-threaded queue abuse, and enhancing the misbehavior scoring mechanism.The Zcash Foundation stated that this update addresses over 80 security reports from the ZCG Vulnerability Disclosure Program (spanning April to May 2026), covering multiple layers including consensus security, memory management, RPC processing, and the P2P network attack surface. Officials emphasized that there is no alternative to this upgrade; upgrading is the only way to ensure nodes do not experience a chain split and remain secure.
According to The Defiant, the Ethereum Foundation’s Kohaku Initiative has released an SDK for integrating privacy protocols into Ethereum wallets. A functional 4337 mempool relay supporting private transactions is now available in version v0.0.1-alpha.21 of the kohaku-eth/railgun integration. This SDK aims to integrate shielded-pool protocols—such as Railgun, Tornado Cash, and Privacy Pools—directly into wallet interfaces, reducing reliance on centralized relay infrastructure. Kohaku has also demonstrated a CLI-based wallet and is advancing integration with production-grade wallets like Ambire, while simultaneously developing post-quantum accounts, multisig support, and hardware wallet compatibility.
