BlockBeats News, April 5th: Jan3 CEO Samson Mow criticized Coinbase CEO Brian Armstrong for once again meddling in Bitcoin technical decisions.
Samson pointed out that the issues Brian Armstrong exposed in the block size war 10 years ago remain unresolved to this day. He lacks humility and a deep understanding of the issues, preferring to set opinions, action plans, and timelines first rather than conduct a thorough analysis. Coinbase’s own address reuse problem has made its wallet infrastructure vulnerable to quantum attacks and has experienced frequent outages during transaction peaks. Samson suggested that Brian should “first heal himself.”
Samson believes that the current threat of quantum computers is not yet real and is not expected to emerge in the next 10-20 years. He argues against hastily switching from ECDSA/Schnorr to post-quantum signatures, suggesting that it is better to “solve it later” to avoid greater risks.
Samson outlined three major drawbacks of a rushed anti-quantum upgrade as follows: first, it may expose Bitcoin to traditional computer attacks at present; second, post-quantum signatures are 10-125 times larger, significantly reducing throughput and potentially leading to “Block Size War 2.0”; third, it could become a Trojan horse introducing RNG or cryptographic backdoors.
