Bitcoin Q&A: Block Reward, Reorg Protection, and Immutability
Channel: aantonop
Date: 2019-09-05

What is the waiting period before miners can spend the block reward / coinbase transaction? Why does this protect against chain reorganization? How much energy would it take to reverse the chain back to the genesis block? Should we sustain immutability with proof-of-work or move to proof-of-stake?
