Account pooling multiple clients' assets under one custodian name, with internal records tracking individual shares. Exposes clients to comingling risk if custodian fails. Blockchain wallets are inherently segregated — each address holds only its own tokens with no comingling.
Start with the shortest useful explanation before going deeper.
Account pooling multiple clients' assets under one custodian name, with internal records tracking individual shares. Exposes clients to comingling risk if custodian fails. Blockchain wallets are inherently segregated — each address holds only its own tokens with no comingling.
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.
Use this compact block when you want to give an agent or assistant grounded context without dumping the entire page.
Omnibus Account (omnibus-account) Category: Blockchain General Definition: Account pooling multiple clients' assets under one custodian name, with internal records tracking individual shares. Exposes clients to comingling risk if custodian fails. Blockchain wallets are inherently segregated — each address holds only its own tokens with no comingling.

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.
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.
An account that holds a balance of a specific token for a specific owner. Token accounts store: mint (which token), owner (who controls it), amount (balance), delegate (optional), and state (initialized/frozen). Each wallet needs a separate token account per token type. Token accounts require ~165 bytes and rent-exempt minimum of ~0.002 SOL.
These are the next concepts worth opening if you want this term to make more sense inside a real Solana workflow.
These entries are easy to mix up when you are reading quickly, prompting an LLM, or onboarding into a new layer of Solana.
A design pattern that replaces the rigid externally-owned account (EOA) model with programmable smart contract wallets capable of custom authentication, gas sponsorship, and batched transactions. ERC-4337 implements this on Ethereum via UserOperations, bundlers, an EntryPoint contract, and paymasters. EIP-7702 (Pectra upgrade, May 2025) extends this by allowing EOAs to delegate to smart contract logic.
A Bitcoin soft fork activated in August 2017 (BIP 141) that separates transaction signature data (witness) from the transaction body, fixing transaction malleability and increasing effective block capacity from 1 MB to approximately 4 MB via a weight unit system. SegWit introduced a versioned witness program structure that enabled future upgrades like Taproot without additional soft forks. It was a prerequisite for the Lightning Network's secure operation.

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.
