Proof of Space (PoSpace) Summary [Cryptocurrency consensus mechanisms]
Proof of Space uses hard disk space as the value used to guarantee a participant’s stake in mining. By allocating disk space, the network participant provides value to the network, which uses this space to solve computational problems. Given low network bandwidth for a lot of regions, making it difficult to transfer large amounts of […]
Proof of Trust (PoT) Summary [Cryptocurrency consensus mechanisms]
In a Proof of Trust system, users in a network gain trust as they participate in special activities within the network. If a user tries to defraud the system, the trust is lost and they lose an equivalent amount in value (the cryptocurrency or token employed). In a Proof of Trust system, “trust” is staked […]
Proof of Elapsed Time (POET) Summary [Cryptocurrency consensus mechanisms]
In this poetically named consensus mechanism, network participants prove that they have slept for a random amount of time before being able to mint a block. POET was released by Intel in 2016 and was originally aimed at trusted computing using Intel CPU’s. A special instruction set called Software Guard Extensions (SGX) allows programs to […]
Proof of Authority (PoA) Summary [Cryptocurrency consensus mechanisms]
Proof of Authority is a consensus mechanism where members of a cryptocurrency network are identified and receive delegated powers to solve blocks. If they defraud the system their identity is at stake and they will either be prosecuted or booted from the network. This is a centralized system where a higher authority delegates mining powers […]
Concepts In This Page
A process or system by which multiple parties are able to reach consensus. In the context of cryptocurrencies, it's the process which allows for everyone to agree on everyone else's money balance. E.g. Bitcoin employs Nakamoto consensus via PoW mining.
Ethereum Virtual Machine (EVM)
The Ethereum Virtual Machine (EVM) is the individual component which enables the worldwide decentralized computing infrastructure on the blockchain. Smart contracts actually run on each individual EVM instance around the world. Miners verify and store results from EVM computing processes on the blockchain.
