Blockchain General

Native Token

The base cryptocurrency of a blockchain network that is used to pay transaction fees, participate in consensus (staking), and compensate validators for securing the network. Native tokens are protocol-level assets — not created by smart contracts — and their issuance is governed by the blockchain's monetary policy. Examples: SOL (Solana), ETH (Ethereum), BTC (Bitcoin).

Mental model

Use the quick analogy first so the term is easier to reason about when you meet it in code, docs, or prompts.

Think of it as a building block that connects one definition to the larger Solana system around it.

Technical context

Place the term inside its Solana layer so the definition is easier to reason about.

Shared crypto concepts that frame the broader ecosystem.

Why builders care

Turn the term from vocabulary into something operational for product and engineering work.

This term unlocks adjacent concepts quickly, so it works best when you treat it as a junction instead of an isolated definition.

Concept graph

See the term as part of a network, not a dead-end definition.

These branches show which concepts this term touches directly and what sits one layer beyond them.

Branch

SOL

The native token of the Solana blockchain, used for paying transaction fees, staking, and rent. 1 SOL equals 1 billion lamports. SOL has an inflationary supply schedule starting at 8% annually, decreasing by 15% per year, with a long-term floor of 1.5%. Transaction base fees (5,000 lamports) are partially burned.

Branch

Gas

A unit measuring the computational effort required to execute operations on a blockchain. On Ethereum, gas is priced in gwei (10^-9 ETH) and varies with network demand. Users set gas limits and gas prices; unused gas is refunded. Solana uses 'compute units' as its equivalent, with much lower costs (~$0.00025 per transaction vs. $1-100+ on Ethereum).

Branch

Transaction Fee

The cost paid by the sender to have a transaction processed and included in a block. Fees compensate validators/miners for computation and prevent spam. Fee models vary: Ethereum uses dynamic gas pricing (EIP-1559 base fee + tip), Solana uses base fee (5,000 lamports) + optional priority fee, Bitcoin uses fee-per-byte.

Blockchain General

Node

A computer running blockchain client software that maintains a copy of the ledger and participates in the network. Node types: full node (validates all transactions, stores full state), archive node (stores complete history), light node (verifies headers only). On Solana, validator nodes require high-end hardware (256+ GB RAM for RPC nodes).

Blockchain Generalerc-6551

ERC-6551 (Token-Bound Accounts)

An Ethereum standard that assigns a smart contract account (wallet) to every ERC-721 NFT, enabling NFTs to own other tokens, NFTs, and interact with protocols directly. Token-bound accounts (TBAs) are created through a permissionless registry using CREATE2 for deterministic addresses. Use cases include gaming inventories, bundled DeFi positions tradable as single NFTs, and identity-linked portfolios.

Governance Token

A token that grants holders voting power over protocol decisions. Governance tokens enable decentralized control of DeFi protocols, DAOs, and blockchain parameters. Examples on Solana: JUP (Jupiter), MNDE (Marinade), RAY (Raydium). Voting power is typically proportional to token holdings, though some systems use quadratic voting or delegation.

Blockchain General

Blockchain

A distributed, append-only ledger that records transactions in cryptographically linked blocks. Each block contains a hash of the previous block, forming an immutable chain. Nodes in the network maintain copies of the ledger and reach agreement through consensus mechanisms. Blockchains enable trustless, decentralized record-keeping without a central authority.

Blockchain General

Consensus Mechanism

The protocol by which nodes in a distributed network agree on the current state of the ledger. Common mechanisms include Proof of Work (Bitcoin), Proof of Stake (Ethereum, Solana), and BFT variants. Consensus ensures all honest nodes converge on the same transaction history despite potential network delays or malicious actors.

Blockchain General

Proof of Stake (PoS)

A consensus mechanism where validators are selected to produce blocks based on the amount of cryptocurrency they have staked (locked) as collateral. PoS is energy-efficient compared to Proof of Work. Misbehaving validators risk losing their stake (slashing). Solana, Ethereum (post-Merge), Cosmos, and Cardano use PoS variants.

Blockchain General

Proof of Work (PoW)

A consensus mechanism where miners compete to solve computationally expensive puzzles to produce blocks and earn rewards. PoW provides strong security (51% attack resistance) but is energy-intensive. Bitcoin and pre-Merge Ethereum use PoW. The difficulty adjusts to maintain target block times regardless of total network hash power.
