Mempool
Financial term in the Crypto category
Definition
Short for 'memory pool,' the mempool is a waiting area where unconfirmed transactions are held before they are picked up by miners or validators and included in a block. When you send a cryptocurrency transaction, it first enters the mempool and waits to be processed based on factors like the fee you paid. During periods of high network activity, the mempool can become congested, leading to longer wait times and higher fees.
Related Terms
Gas Fee
A transaction fee paid to validators or miners on a blockchain network to process and confirm transactions. On Ethereum, gas fees fluctuate based on network demand, meaning they can be very low during quiet periods and spike during times of high activity. Understanding gas fees is important because they directly affect the cost of sending crypto, swapping tokens, or interacting with smart contracts.
Mining (Cryptocurrency)
The process of using specialized computer hardware to solve complex mathematical puzzles in order to validate transactions and add new blocks to a blockchain. Miners are rewarded with newly created cryptocurrency and transaction fees for their computational work. This process is central to Proof of Work blockchains like Bitcoin and requires significant electricity and computing power.
Blockchain
A distributed digital ledger that records transactions across a network of computers in a way that makes the data nearly impossible to alter retroactively. Each block contains a set of transactions and is cryptographically linked to the previous block, forming a chain. This technology provides transparency, security, and decentralization without requiring a central authority.
Layer 2
A secondary protocol or framework built on top of an existing blockchain (Layer 1) to improve its scalability and transaction speed. Layer 2 solutions process transactions off the main chain and then settle the results back on Layer 1, reducing congestion and lowering fees. Popular examples include Polygon and Arbitrum for Ethereum, and the Lightning Network for Bitcoin.
