Monthly Update on Blockchain Technology: Pectra testnet activation, zero-knowledge gossip, BNBChain roadmap
Written by: GaryMa, WuBlockchain In February, blockchain technology had the following major updates: Bitcoin ● Zero-Knowledge Gossip for Lightning Network Channel Announcements : A recent proposal suggests improving channel announcements using “zero-knowledge gossip,” a privacy-preserving technique. This allows other nodes to verify whether a channel is valid (backed by funds) without revealing specific details, preventing malicious attacks while protecting user privacy. ● Erlay Protocol Update : Erlay is a new approach aimed at reducing the bandwidth (data traffic) required for transaction propagation in the Bitcoin network. Research indicates that by adjusting “fanout” (the method of broadcasting transactions) and “set reconciliation” (efficient data synchronization), bandwidth usage can be reduced by 35%-45%, though it may slightly increase transaction propagation delays. ● Simulating the OP_RAND Opcode : Bitcoin currently lacks direct support for random number operations (OP_RAND)....
