The Bitcoin Attacks are NOT About Money | Simon Dixon
Notas do episódio
Mentor Sessions Ep. 087: Simon Dixon breaks down the Coldcard hack, BIP-110 chain split fallout, node vs miner power, and Bitcoin self-custody security in 2026.
PART 1: Simon Dixon & Doomberg - https://youtu.be/Q0P0X7j_kcA
Over $100 million in Bitcoin vanished in the Coldcard entropy bug — and days later a chain split ended with the nodes defeated and Bitcoin more centralized than before. Simon Dixon joins Nathan to trace what really happened.
This is the deep-dive follow-up to the Doomberg conversation. You'll learn why Simon now treats every incident as an attack "guilty until proven innocent," how the BIP-110 resistance became the most successful node mobilization since the block size war yet still failed to move the mining pools, and why he refuses to die on a hill that ends in an altcoin. You'll see how the Coldcard low-entropy vulnerability, Zeus, Boltz and BTCPay attacks fit one pattern, and hear a clear framework for rebuilding your self-custody with dice-rolled entropy, multisig, and active participation. Simon and Nathan also unpack developer centralization, the loss of Knots as a competing implementation, and why sovereignty is proof of work you can't outsource.
