New quadratic delays in Bitcoin scripts

I have a fixation with algorithm complexity. When I was young I was an early optimizer, and, I must admit, that didn’t help me much in dates. Today I occasionally code a sub-optimized algorithm when there is no need for high performance, but it stills bothers me when I do. When I review code, it […]


The relation between Segwit and AsicBoost, covert and overt

I will try to explain the relation between Segwit and AsicBoost, in both the covert and overt forms, in certain detail. I will also try to explain why a method was recently proposed to reduce the interference between covert-AsicBoost and some protocol improvements, by reducing the incentives for covert AsicBoost. The proposal makes covert AsicBoost more expensive, […]
