A blockchain upgrade that turns user wallets into programmable smart contracts, enabling features like social recovery, gas sponsorship, and batch transactions.
A web-based tool that allows users to search and browse blockchain data, including transactions, addresses, blocks, and smart contracts.
A decentralized, immutable digital ledger that records transactions across a network of computers.
A protocol that connects two blockchains, enabling users to transfer tokens and data between different networks.
The method by which a blockchain network agrees on the current state of the ledger and validates new transactions.
The ability to transfer assets, data, and messages between different blockchain networks, enabling a connected multi-chain ecosystem.
An application built on a blockchain that operates through smart contracts, offering services without centralized control or single points of failure.
A financial ecosystem built on blockchain technology that provides traditional financial services like lending, trading, and insurance without banks or intermediaries.
Blockchain networks that incentivize individuals to build and maintain real-world physical infrastructure like wireless networks, compute, and sensors using token rewards.
An uncollateralized DeFi loan that must be borrowed and repaid within a single blockchain transaction, enabling arbitrage and complex financial operations.
The cost paid by users to compensate for the computing energy required to process and validate transactions on a blockchain network.
The maximum amount of computational work a user is willing to pay for in a transaction, or the maximum gas allowed in a single block.
A programmed event that cuts the Bitcoin mining reward in half approximately every four years, reducing the rate of new BTC creation and increasing scarcity.
A permanent divergence in a blockchain where nodes running the old software cannot validate blocks produced by updated nodes, potentially creating two separate chains.
A fixed-length alphanumeric string generated from input data of any size, used to verify data integrity and secure blockchain transactions.
A secondary network built on top of a base blockchain (Layer 1) that processes transactions off-chain to increase speed and reduce costs while inheriting the security of the main chain.
The primary, live blockchain network where real transactions occur with actual cryptocurrency that has economic value.
A waiting area where unconfirmed blockchain transactions queue before being selected by validators or miners for inclusion in the next block.
The profit that block producers can extract by reordering, inserting, or censoring transactions within a block, often at the expense of regular users.
A unique digital asset on a blockchain that represents ownership of a specific item such as art, music, game items, or real estate deeds.
A computer that maintains a copy of the blockchain and helps validate and relay transactions across the network.
Refers to transactions, data, and activities recorded directly on a blockchain, publicly verifiable and permanently stored in the distributed ledger.
A service that provides smart contracts with external real-world data such as asset prices, weather, or sports scores that blockchains cannot access natively.
A cryptographic secret that proves ownership of a blockchain address and is required to sign transactions, essentially serving as the password to your crypto wallet.
A consensus mechanism where validators are chosen to create new blocks based on the amount of cryptocurrency they have staked as collateral.
A consensus mechanism where miners compete to solve complex mathematical puzzles to validate transactions and create new blocks, earning cryptocurrency rewards.
A Layer 2 scaling solution that executes transactions off-chain and posts compressed data to the main blockchain for security.
A penalty mechanism in Proof of Stake blockchains that destroys a portion of a validator's staked tokens for malicious behavior or severe negligence.
A self-executing program stored on a blockchain that automatically enforces the terms of an agreement when predefined conditions are met.
The process of locking up cryptocurrency to support blockchain operations and earn rewards, typically in Proof of Stake networks.
The cryptocurrency earnings received by token holders who participate in network validation by locking up their tokens in a Proof of Stake blockchain.
A separate blockchain network used by developers to test applications and protocol changes without risking real cryptocurrency.
A set of rules and interfaces that define how tokens behave on a blockchain, ensuring compatibility across wallets, exchanges, and DeFi protocols.
A network participant that verifies transactions and produces new blocks in a Proof of Stake blockchain, earning rewards for securing the network.
The vision of a decentralized internet built on blockchain technology, where users own their data, identity, and digital assets.
A token on one blockchain that represents an asset from another blockchain, enabling cross-chain usage in DeFi and other applications.
