問題文

A team that must know who stands behind a dealing joins a ledger of this sort, and it is told that the ledger is built on asymmetric-key cryptography. It puts two questions to the chapter on keys and identity: which of two counts the chapter says need not stand one to one, and what can tie a dealing on such a ledger to a real name. Which count need not stand one to one, and what can tie a dealing to a real name?
