The others are Proof of Stake (PoS) and Delegated Proof of Stake (DPoS). The error-free and secure operation of the blockchain system depends on these consensus mechanisms. They are used, particularly in the mining process.
WebApr 16, 2024 · Commitments are fundamental in cryptography. In the classical world, commitments are equivalent to the existence of one-way functions. It is also known that the most desired form of commitments in terms of their round complexity, i.e., non-interactive commitments, cannot be built from one-way functions in a black-box way [Mahmoody …
