What if user try to tamper the last block in blockchain?


It is said that when we try to tamper second block, then the hash of that block gets changed so the block after it will have different previous hash due to which the link gets broken and that block is invalid. But what if the very last block is tampered? Because there wont be any block after it. Just the scenario to understand assuming there is last block only for some time.


Hi @opensource,

This forum isn’t focused on blockchain/crypto-tech. You’ll be able to get a better answer on a forum actually focused on blockchain. The blockchain subreddit might be able to answer your question: https://old.reddit.com/r/BlockChain/
