Replay Attack Fears Grow as BIP-110 Fork Revival Looms
A revival of the failed BIP-110 fork is in the works, putting replay attacks back in the spotlight. Replay attacks occur when a transaction intended for one blockchain can be copied onto another.
According to Luke Dashjr, Bitcoin should handle replay protection, which he calls 'Spamcoin.'
The BIP-110 chain peaked at 2.53% miner support before stalling on August 8th. The emerging plan does not provide automatic, comprehensive two-way replay protection.
Bitcoin Knots is implementing a new sighash option that can create a transaction valid on the RDTS chain but invalid under Bitcoin Core. This approach leaves users responsible for knowing which transactions can bleed across chains.
