BlockBeats News, April 5th, Jan3 CEO Samson Mow criticized Coinbase CEO Brian Armstrong for once again meddling in Bitcoin technical decision-making.
Samson pointed out that the issues Brian Armstrong exposed during the block size war 10 years ago remain unresolved to this day. He lacks humility and a deep understanding of the issues, opting to set the tone for opinions, action plans, and timelines rather than analyzing trade-offs first. Coinbase's own address reuse issue has left its wallet infrastructure vulnerable to quantum attacks and has experienced frequent outages during transaction peak times, prompting Brian to "fix himself first."
Samson believes that the current threat of quantum computing is not yet real and is not expected to materialize within 10-20 years. Therefore, he suggests not hastily switching from ECDSA/Schnorr to post-quantum signatures but rather addressing it "the later, the better" to avoid greater risks.
Samson elaborated on the three major drawbacks of a hasty anti-quantum upgrade as follows: first, it may expose Bitcoin to traditional computer attacks; second, post-quantum signatures are 10-125 times larger, significantly reducing throughput and risking a "Block Size War 2.0"; and third, it could become a Trojan horse introducing RNG or cryptographic backdoors.
