A proof market is a decentralized marketplace where users can buy and sell cryptographic proofs to verify ownership, the validity of a particular transaction and the authenticity of a piece of information or computation results.
Proof of Attendance Protocol (POAP) refers to a business offering to use the ERC-721 NFT protocol on Ethereum to ascribe individuals a unique, non-fungible blockchain-based identifier that only the person can access
Proof of Reserves (PoR) is a method of using cryptographic verification to demonstrate possession of digital assets.
Proof of Stake Authority is an innovative consensus algorithm that represents a hybrid of Proof-of-Stake and Proof-of-Authority.
A blockchain consensus mechanism that delivers comparatively fast transactions using identity as a stake.
Proof-of-burn is an attempt at creating a system that can prevent fraudulent transactions on a blockchain and can also improve the overall efficiency and functioning of the blockchain.
A blockchain consensus mechanism aiming to bootstrap one blockchain to another with increased energy efficiency, by verifying that a cost was incurred in “burning” a coin by sending it to an unspendable address.
Any verification that provides evidence of a real, living software developer who created a cryptocurrency, in order to prevent an anonymous developer from making away with any raised funds without delivering a working model.
Proof-of-donation refers to the integration of charitable donations into the functionality of a blockchain.
Proof of History (PoH) nodes have internal clocks that validate events and time. The incoming events are hashed using a verifiable delay function, also known as VDF, that increases the speed and scalability of a blockchain.
Proof-of-Immutability (PoIM) is a novel blockchain architecture designed to protect data privacy in a distributed network. PoIM enables the blockchain to persist data in a decentralized and provably immutable manner, without having to distribute the data among nodes.
Proof-of-replication (PoRep) is the way that a storage miner proves to the network that they are storing an entirely unique copy of a piece of data.
In simplest terms, PoSt means that someone can now guarantee that they are spending a certain amount of space for storage.
A blockchain consensus mechanism in addition to Proof-of-Work that maintains the integrity of blockchain.
Proof-of-Time (PoT) is a decentralized, scalable, verifiably secure, and environmentally-friendly consensus algorithm that checks event data by choosing validators based on their ranking scores and a fixed stake.
Proof-of-validation (PoV) is a unique proof-of-stake (PoS) consensus mechanism that works to achieve consensus through staked validator nodes.
A blockchain consensus mechanism involving solving of computationally intensive puzzles to validate transactions and create new blocks. *see Proof-of-Stake (PoS).
