Builders engaged on the Bitcoin layer 2 Lightning Community have develop into much less security-oriented and extra centered on producing money circulate for his or her traders, argues a former Lightning Community developer.

There may be little [I and others] can do to halt the haemorrhage, with out compromising the core values of censorship-resistance and permissionless of the Lightning Community.”
Lightning is one of the best resolution at present obtainable, nevertheless it’s not adequate.
Lightning has a number of elementary flaws, the place every of them make the system as a complete a useless finish for bitcoin, long run. An try at explaining these, and what we must always do as a substitute.
