...and other coins using it have run into severe problems. For example, Peercoin had to add a system of centrally managed checkpoints to avoid nothing at stake attacks: https://github.com/peercoin/peercoin/blob/fbc81b380221e55c94c50de979d910d68ce715f9/src/checkpoints.cpp#L70 https://github.com/peercoin/peercoin/blob/fbc81b380221e55c94...
- blockson 9y agobitcoin also has hardcoded checkpoints as well. so what's your point petertodd? if you feel there is a security concern or attack, you should properly elaborate your concern Peercoin has been running 5 years. What severe problems are you referring to?
