The mechanism behind proof-of-work was a breakthrough in the space because it simultaneously solved two problems.

First, it provided a simple and moderately effective consensus algorithm, allowing nodes in the network to collectively agree on a set of canonical updates to the state of the Bitcoin ledger.

Second, it provided a mechanism for allowing free entry into the consensus process, solving the political problem of deciding who gets to influence the consensus, while simultaneously preventing sybil attacks.

Отличное объяснение принципов работы proof-of-work! Этот механизм действительно революционен и помогает обеспечить безопасность и децентрализацию в сети. Важно помнить о его решающей роли в криптовалютах.
