A seed node is a known network endpoint that helps a new peer discover other participants and begin joining a peer-to-peer network.…
Segregated Witness is a Bitcoin upgrade that separates signature witness data from transaction identifiers and introduces a weight-based block limit. Removing witness…
A SegWit address encodes a Bitcoin witness program, directing funds to spending conditions evaluated under Segregated Witness rules. Version 0 commonly represents…
A sentry node is a public-facing peer that shields a validator or protected node by relaying traffic and reducing direct network exposure.…
A sequencer node runs software that accepts transactions, determines their order, and produces candidate blocks or batches for a rollup or chain.…
A settlement layer is the blockchain or protocol layer that accepts final state commitments, resolves disputes or verifies proofs, secures asset custody…
A shard validator verifies and helps finalize transactions or data assigned to a particular shard under the network's validator-allocation rules. Networks may…
Sharding is a scaling technique that partitions data or computation so multiple network subsets can process different workloads in parallel. Designs vary…
A shared mempool is a transaction pool whose contents are propagated or jointly maintained among multiple block producers, sequencers, or validators. Shared…
A sidechain is an independent blockchain connected to another blockchain through a bridge or two-way asset-transfer mechanism. It can use different validators,…
A sidechain bridge locks, releases, burns, or mints assets and relays messages between a sidechain and another blockchain. Verification may rely on…
Simple Serialize is Ethereum consensus-layer serialization with deterministic encodings and Merkleization rules for specialized structured data and compact proofs. SSZ separates serialization…
A smart contract is blockchain-executed code that deterministically reads state and applies permitted changes when transactions or messages invoke it. Contracts can…
Snowman consensus is Avalanche's linear-chain consensus protocol, repeatedly sampling validators to build probabilistic confidence in one preferred block history. Because blocks form…
Social consensus is community agreement about legitimate rules, history, or governance when software alone cannot resolve a protocol-level dispute. Nodes enforce executable…
A soft fork tightens blockchain validity rules so upgraded nodes reject some blocks that older nodes would still accept. Compatibility does not…
Soft fork activation is the process that determines when upgraded consensus restrictions begin being enforced by participating blockchain nodes. The activation method…
A Solana address is a 32-byte public identifier for an account, represented in base58 and derived from a key or program. Key-backed…
The Solana Firedancer Client is an independently developed validator implementation built from the ground up for high performance, security isolation, and client…
Solana is a high-throughput proof-of-stake blockchain where validators execute programs, maintain account state, and order transactions through its consensus and runtime. The…
A sovereign rollup publishes data to another layer but has its own nodes determine validity, execution rules, forks, and canonical state. Users…
A sponsored transaction is a blockchain transaction whose network fee is paid or reimbursed by someone other than the user authorizing the…
A stake account is a dedicated on-chain account that records delegated stake, authorities, activation state, and rewards under a staking protocol. Delegation…
