A protocol that enables transferring assets or data between different blockchains. Bridges use mechanisms like lock-and-mint (lock on source, mint wrapped on destination), liquidity pools, or relay networks. Bridges are high-value attack targets—Wormhole ($320M, 2022), Ronin ($625M, 2022). Wormhole is Solana's primary bridge to Ethereum and other chains.

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.
Place the term inside its Solana layer so the definition is easier to reason about.
Shared crypto concepts that frame the broader ecosystem.
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.

Bridge (Cross-Chain) (bridge) Category: Blockchain General Definition: A protocol that enables transferring assets or data between different blockchains. Bridges use mechanisms like lock-and-mint (lock on source, mint wrapped on destination), liquidity pools, or relay networks. Bridges are high-value attack targets—Wormhole ($320M, 2022), Ronin ($625M, 2022). Wormhole is Solana's primary bridge to Ethereum and other chains. Aliases: Cross-Chain Bridge Related: Wormhole
Use glossary context, relationships, mental models, and builder paths to get structured answers instead of generic chat output.
Optional: paste Anchor, Solana, or Rust code so the Copilot can map primitives back to glossary terms.
The Copilot will answer using the current term, related concepts, mental models, and the surrounding glossary graph.
These branches show which concepts this term touches directly and what sits one layer beyond them.
The primary cross-chain messaging and bridge protocol for Solana, enabling asset transfers between Solana, Ethereum, and 20+ other chains. Wormhole uses a network of 19 Guardian nodes that observe and attest to cross-chain messages. The protocol was exploited for $320M in Feb 2022 (patched). It supports token transfers, NFT bridging, and arbitrary message passing.
These are the next concepts worth opening if you want this term to make more sense inside a real Solana workflow.

These entries live beside the current term and help the page feel like part of a larger knowledge graph instead of a dead end.
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.
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.
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.
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.
