Payment Protocol
A payment protocol defines the messages, fields, states, validation rules, and interactions used to request, execute, and confirm payments. The protocol is…
Payout Transaction Hash
A payout transaction hash is the blockchain identifier of the transaction submitted to deliver a specific payout. It lets operators retrieve network…
Peer-to-Peer Network
Peer-to-Peer Network is the communication model in which blockchain nodes connect directly to other nodes to discover peers, exchange transactions and blocks,…
Polygon Bridge
Polygon Bridge refers to bridge mechanisms and interfaces used to transfer supported assets or messages between Ethereum and Polygon networks. PoS and…
Polygon Network
Polygon PoS is a separate blockchain network in the Polygon ecosystem that offers EVM-compatible transactions and tokens. It uses its own ledger,…
Portal Bridge
Portal Bridge is a Wormhole-based interface for transferring supported assets across blockchains through configured wrapped-token and other transfer routes. The interface may…
Private Mempool
A private mempool is a non-public pathway or pool in which pending transactions are submitted to selected parties rather than broadcast through…
Probabilistic Finality
Probabilistic finality means a transaction becomes increasingly unlikely to be reversed as additional accepted blocks or consensus weight accumulate.
Program Data Account
A Program Data Account is a Solana account that stores an upgradeable program's executable code and its upgrade authority metadata. Separating the…
Program Derived Address (PDA)
A Program Derived Address is a deterministic Solana address derived from a program ID and seeds without a corresponding private key. The…
Proof of Attendance Protocol (POAP)
POAP is a system for issuing collectible digital badges that attest a wallet participated in or attended a defined event. A POAP…
Proof of Space
Proof of Space is a cryptographic mechanism demonstrating that a participant has dedicated a measurable amount of storage capacity. Blockchain designs can…
Proof of Stake (PoS)
Proof of stake is a family of blockchain consensus mechanisms in which participants lock or commit assets to qualify for block production…
Proof of Stake Coin
A Proof of Stake coin is a blockchain's native asset used to weight, bond, reward, or delegate participation in PoS consensus. Holding…
Proof of Work (PoW)
Proof of work is a consensus mechanism in which block producers demonstrate costly computation, usually by finding a block hash below a…
Proof of Work / Proof of Stake Hybrid
A Proof of Work and Proof of Stake hybrid combines mining with stake-based voting, finality, eligibility, or governance in one consensus design.…
Proof of Work Coin
A Proof of Work coin is the native monetary asset of a blockchain whose block history is secured through mining. The coin…
Protocol Bridge
A protocol bridge is a cross-chain mechanism whose contracts, verifiers, messages, and relayers are governed by a defined interoperability protocol. Security may…
Protocol Layer
A protocol layer is a functional level that applies specific rules and exposes defined services to components above or beside it. Layering…
Protocol Reserve
A protocol reserve is a pool of controlled assets intended to cover obligations, absorb losses, fund operations, or support system stability. Reserve…
Protocol Revenue
Protocol revenue is value captured for protocol-controlled recipients from fees or other activities under a stated accounting methodology. Gross user fees are…
Prover Node
A prover node reconstructs a computation or state transition and generates a cryptographic proof that a verifier can check efficiently. The verifier…
Pruned Node
A pruned node validates blockchain history but deletes selected older block or state data after retaining what current operation requires. It can…
