A blockchain upgrade that turns user wallets into programmable smart contracts, enabling features like social recovery, gas sponsorship, and batch transactions.
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.
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 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.
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 service that provides smart contracts with external real-world data such as asset prices, weather, or sports scores that blockchains cannot access natively.
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 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.
A token on one blockchain that represents an asset from another blockchain, enabling cross-chain usage in DeFi and other applications.
