Isn't distributing it the means by which it's made immutable? i.e. you can't mutate it unless you control at least half the network?

- alkonaut 5y agoA centralized blockchain can be a publicly readable ledger that is still only writable by trusted parties. A git repo works in a similar way. For example: a bank uses a public ledger to store all transactions. If a mistake is made, they can correct it, but not by removing/changing the past transaction, only by adding another transaction to the chain which corrects it. Everything is transparent to observers, but obviously I can’t mutate my own account balance without transfering money to my account. The major drawback of these write-only ledgers is the same as in git: if you accidentally write a secret to the chain, it’s there forever.
