THORChain officials stated that a large number of fake accounts and false information have appeared in the market, involving activities such as "refunds," "airdrops," and "compensations"; preliminary investigations show that user funds were not harmed in the previous security incidents, and no refund, airdrop, or compensation plans are currently underway. Any accounts claiming otherwise are impersonating or spreading false information. Progress on the investigation and more information will be announced later.

According to CoinDesk, the Solana core development team Anza announced that a major consensus mechanism upgrade codenamed Alpenglow has gone live on the community test network, allowing validators to switch from the current Proof-of-Stake + Proof-of-History + TowerBFT architecture to the new consensus framework in the test cluster.The upgrade aims to significantly shorten transaction finality time and improve network response efficiency by restructuring the validator communication and block confirmation process. This test marks that validators can now perform the "Alpenswitch" migration operation in a real environment. Solana co-founder Anatoly Yakovenko previously stated that if the testing goes smoothly, Alpenglow is expected to be deployed to the mainnet as early as next quarter.

The Mantle community has authorized the Mantle Treasury to provide a loan of up to 30,000 ETH to the Aave DAO through proposal MIP - 34, to address the bad debt impact caused by the rsETH cross-chain bridge security incident on Aave V3.According to the proposal, the loan term is up to 36 months, with an interest rate of LIDO + 1% annualized, and the borrower can repay early without penalty. In terms of risk control, Mantle will have priority security rights over the relevant collateral assets, and Aave will also provide additional collateral in the form of Aave tokens and protocol revenue worth no less than $11 million, and will delegate 130,000 Aave tokens to Mantle for governance participation.

The WLFI community voted to pass the proposal for the "Token Unlocking Plan for Early Supporters and Founding Team," with a support rate of 99.9%.The proposal includes that approximately 17 billion WLFI held by early supporters will adopt a 2-year cliff unlock + 2-year linear unlock (a total of 4 years); approximately 45.2 billion WLFI held by the founding team, advisors, and partners can choose a 2-year cliff unlock + 3-year linear unlock (a total of 5 years), and may voluntarily burn 10% of it permanently; tokens that do not actively accept the new plan will remain permanently locked but retain governance participation rights.

According to FinanceFeeds, Alex Thorn, the research director of Galaxy Digital, stated that as advancements in quantum computing hardware accelerate, the Bitcoin community is shifting from decentralized debates to forming a preliminary consensus on quantum threats. The core direction is to gradually introduce post-quantum cryptography (PQC) through soft forks, achieving an upgrade of the address system and long-term security assurance.The report points out that the current Bitcoin signature mechanism, which uses the Elliptic Curve Digital Signature Algorithm, can theoretically be cracked by Shor's algorithm. Approximately 2 million BTC from early p2pkh addresses are at risk because their public keys have been exposed, facing the potential risk of "collecting first and decrypting later." The community tends to promote a "migration window" mechanism to guide users in transferring their assets to new quantum-resistant addresses, and after a multi-year grace period, to implement freezing or destruction of untransferred assets to prevent large-scale market impacts in extreme situations. Additionally, the consensus includes enhancing "cryptographic agility," which allows protocols to switch signature algorithms without interrupting the network.The current proposal leans towards a dual-signature mechanism that uses ECDSA and PQC (such as Dilithium) in parallel, ensuring security redundancy while facilitating a smooth transition. Analysts believe that this approach transforms the quantum threat from a "black swan event" into a manageable technological upgrade, helping to solidify Bitcoin's security foundation as a long-term store of value asset.

Printr founder Jason Ma announced on the X platform that he is stepping down as CEO, with COO and GTM head Lennon immediately taking over as CEO, while co-founder Lea will continue to serve as CTO. He will transition to an advisory role.At the same time, Printr announced that it will fully refund the community fundraising, with the related refund process expected to be announced within 7 days. The team stated that this move aims to rebuild community trust, and the platform's products, team, and development roadmap will remain unchanged.

According to on-chain analyst Ai Yi's monitoring, Bitcoin briefly fell below $77,000. The "set 10 big targets" whale @Jason60704294 previously opened a long position of 397.718 BTC, which is currently at a floating loss of $178,000, with a maximum floating loss of $488,000 in the early morning.Yesterday afternoon, Binance saw a buy order for 2,759.11 BTC at a price of $77,686.5, worth $214 million. The community speculates that this position belongs to the whale; if true, the current floating loss would expand to $1.237 million.

Circle stated on the X platform that Circle Ventures is purchasing AAVE tokens because strong DeFi infrastructure does not build itself.Aave is helping to shape the future of on-chain finance, and Circle is supporting this ecosystem and the entire community built around it.

Arkham posted on the X platform that Avi Eisenberg, the attacker who profited approximately $110 million in 2022 by manipulating the price oracle of Mango Markets, has recently signed a transaction with his on-chain address, drawing widespread attention from the community.Avi Eisenberg previously exploited a vulnerability in Mango Finance to conduct "high-profit trades," and later threatened to attack Aave. He was also liquidated on Curve while attempting to liquidate others' positions, and was arrested and imprisoned after the incident. Now, his address has reappeared with on-chain activity, leading the market to speculate whether he has returned to the crypto market, although no further details have been disclosed yet.

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.

The DeFi Education Fund, along with Aave Labs, Uniswap Labs, Paradigm, Andreessen Horowitz, and other organizations, has sent a letter to the U.S. SEC in response to the recent statement released by the trading and markets division regarding the registration of "non-custodial user interface" brokers for crypto asset securities.The signatories support the statement that the "non-custodial user interface," which only provides a technical entry point and allows users to manage their assets independently, should be excluded from broker registration. They also urge the SEC to establish clearer and more sustainable definitions of "broker" through formal rulemaking, to avoid incorrectly categorizing neutral software tool providers, validators, RPC/API, oracles, cloud services, and other infrastructure under broker regulations. This would provide long-term legal certainty for blockchain infrastructure innovation while ensuring investor protection.Previously, the SEC's trading and markets division indicated that some DeFi trading interfaces do not need to register as brokers, allowing for policy space for related applications. Supporters believe that the new regulations could cover infrastructure participants such as validators, APIs, and oracles. Currently, the U.S. crypto market legislation, the CLARITY Act, is stalled in the Senate.

The ether.fi community has released a proposal to "Utilize treasury funds to restore the collateral assets of rsETH." The proposal includes injecting 5,000 ETH into the rsETH special rescue pool to cover the collateral gap, protect user assets, and prevent bad debts from spreading in the DeFi system.

According to CoinDesk, Cardano's core development company Input Output submitted nine funding proposals for the 2026 community treasury, totaling $46.8 million, a significant reduction of about 52% from last year's $97.5 million, marking the first step towards gradually reducing reliance on community funds.The nine proposals focus on two main directions: first, the consensus upgrade plan Leios, which is expected to increase Cardano's transaction processing capacity by 10 to 65 times, aiming to exceed 1,000 transactions per second, with testing planned for June and full launch by the end of the year; second, the Bitcoin DeFi system Pogun, which allows Bitcoin holders to lend and earn through Cardano without having to trust centralized institutions, with lending features expected to be publicly released in the second quarter.This voting involves about 1,000 elected representatives (DReps), with the voting deadline set for May 24. The results will test whether the Cardano community views Input Output as a regular funding applicant.Meanwhile, the new stablecoin USDCx in the Cardano ecosystem has reached a circulation of 14.6 million coins within weeks of its launch, and the total locked assets on the network have increased from $137.5 million to $142.7 million.

According to market news, Cypherpunk Jameson Lopp and several experts in the field of Bitcoin quantum security have proposed Bitcoin Improvement Proposal BIP-361, which suggests freezing quantum-vulnerable addresses, including Satoshi Nakamoto's reserves, to prevent future quantum computers from stealing approximately 1.7 million Bitcoins.The proposal is to be implemented in three phases: first, prohibiting transfers to legacy addresses; second, invalidating legacy signatures and freezing untransferred assets after five years; and finally, allowing some users to recover frozen funds through a zero-knowledge proof mechanism. This proposal aims to promote the migration of the entire network to quantum-resistant addresses, but it has faced opposition from some community members who believe it contradicts the decentralized ethos of Bitcoin and has a predatory nature.
