Consensus Mechanism↕ | How It Works↕ | Energy Use↕ | Used By↕ | Known For↕ |
|---|---|---|---|---|
Proof of Work (PoW) | Miners solve cryptographic puzzles, first to solve wins block reward | Extremely high — Bitcoin uses more electricity than some countries | Bitcoin, Litecoin, Dogecoin, Monero | Satoshi Nakamoto's original design, SHA-256 mining, ASIC farms, China mining ban, energy debate, most battle-tested mechanism |
Proof of Stake (PoS) | Validators stake coins as collateral, selected to propose blocks proportionally | Very low — 99.95% less than PoW | Ethereum (post-Merge 2022), Cardano, Solana, Polygon | Ethereum's 'Merge' was biggest crypto event ever, slashing penalties for bad actors, no mining hardware needed, green crypto |
Delegated Proof of Stake (DPoS) | Token holders vote for a fixed number of delegates who validate | Very low | EOS, TRON, Lisk, Ark | Representative democracy for blockchains, only 21 block producers (EOS), fast but criticized as too centralized, Dan Larimer's invention |
Proof of Authority (PoA) | Pre-approved validators identified by reputation, not stake | Minimal | VeChain, private Ethereum networks, consortium chains | Identity-based trust, used in enterprise blockchains, validators risk reputation not money, fastest consensus, not truly decentralized |
Proof of History (PoH) | Cryptographic clock creates verifiable passage of time before consensus | Low-moderate | Solana | Solana's secret sauce for 65K TPS, SHA-256 sequential hashing as a clock, Anatoly Yakovenko's innovation, enables parallel processing |
Proof of Space (PoSpace) / Proof of Capacity | Miners pre-compute and store solutions on hard drives | Low (storage-based, not computation) | Chia, Burstcoin, Spacemesh | Bram Cohen (BitTorrent creator) founded Chia, uses hard drive space instead of compute, caused HDD shortage in 2021 |
Proof of Burn (PoB) | Miners permanently destroy coins to earn right to mine | Low | Slimcoin, Counterparty (initial distribution) | Send coins to unrecoverable address to 'burn' them, deflationary by design, proves commitment by destroying value, rarely used |
Proof of Elapsed Time (PoET) | Trusted hardware (Intel SGX) assigns random wait times, shortest wins | Very low | Hyperledger Sawtooth | Intel's contribution to blockchain, requires trusted execution environment, lottery-based fairness, enterprise-focused |
Byzantine Fault Tolerance (BFT/PBFT) | Validators reach consensus through multiple rounds of voting | Low | Hyperledger Fabric, Tendermint/Cosmos, Zilliqa | Solves the Byzantine Generals Problem (1982), works as long as <1/3 nodes are malicious, instant finality, classic distributed systems |
Proof of Importance (PoI) | Factors in stake amount, transaction activity, and network participation | Low | NEM (XEM), Symbol (XYM) | Rewards active participants not just rich holders, 'importance score' considers real usage, more egalitarian than pure PoS |
Directed Acyclic Graph (DAG) | Each transaction confirms 2+ previous transactions, no blocks or miners | Minimal — users do the validation | IOTA (Tangle), Nano, Hedera Hashgraph | No blocks, no miners, no fees, each user is a validator, designed for IoT microtransactions, IOTA's Tangle, theoretically infinite scalability |
Proof of Coverage (PoC) | Miners prove they provide wireless network coverage via radio challenges | Low (radio hotspot hardware) | Helium (HNT) | Mining by providing real-world wireless coverage, 'People's Network', 900K+ hotspots deployed, DePIN pioneer, real utility mining |
Nominated Proof of Stake (NPoS) | Nominators back validators with their stake, validators are elected | Very low | Polkadot (DOT), Kusama | Gavin Wood's design for Polkadot, nominators share rewards AND slashing risk, sophisticated election algorithm, parachain auctions |
Proof of Activity (PoA hybrid) | Combines PoW mining of empty block headers + PoS validation of full blocks | Moderate | Decred (DCR) | Best of both worlds (PoW security + PoS governance), Decred's hybrid model, ticket-based voting, community governance focus |
Avalanche Consensus | Repeated random subsampling — nodes query random peers until consensus emerges | Low | Avalanche (AVAX) | Cornell professor's breakthrough (Emin Gün Sirer), probabilistic finality in <2 seconds, inspired by gossip protocols, highly scalable |
