The WuBlockchain summarizes key developments in the blockchain technology space for May:
Bitcoin
Paradigm researcher Dan Robinson proposed a scheme called PACTs (Provable Address-Control Timestamps). It allows Bitcoin holders to generate proof of their control over an address via a blockchain timestamp mechanism without transferring assets or triggering on-chain activity. This records ownership before future quantum computing gains the capability to crack private keys, and can be used to claim assets in a subsequent quantum-safe version of the Bitcoin network. The scheme aims to provide a preparation path for long-unmoved addresses to counter potential quantum threats.
The Bitcoin Core Project released a high-severity security advisory (CVE-2024–52911), stating that between Bitcoin Core versions 0.14.0 and 29.0, nodes could trigger a memory error when validating specially crafted blocks, leading to a remote crash. The announcement pointed out that the vulnerability stems from cached data being released early during the transaction validation process and subsequently accessed by a background thread. If an attacker can construct a block with sufficient hashing power, it could cause nodes to crash, and there is even a potential risk of remote code execution.
Alex Thorn, Head of Research at Galaxy Digital, stated that the Bitcoin community is gradually reaching a preliminary consensus regarding quantum computing threats. First, the majority view is that Satoshi’s P2PK address assets should not be interfered with, in order to preserve Bitcoin’s core property rights attributes. Meanwhile, because Satoshi’s assets are scattered across approximately 22,000 addresses (50 BTC per address) rather than a single giant “honeypot,” the actual risk of suffering a comprehensive quantum computing attack is lower than expected. Second, the community generally supports developing and testing post-quantum (PQ) cryptography technologies for…
