An Ethereum address encoding that is partly compatible with the International Bank Account Number IBAN encoding, offering a versatile, checksummed, and interoperable encoding for Ethereum addresses. A hard fork of Ethereum at block , to introduce an exponential difficulty increase aka difficulty bomb , motivating a transition to proof-of-stake.

A user interface that typically combines a code editor, compiler, runtime, and debugger. Once a contract's or library's code is deployed, it becomes immutable. Standard software development practices rely on being able to fix possible bugs and add new features, so this represents a challenge for smart contract development.

A transaction sent from a contract account to another contract account or an EOA see message. Also known as a "password stretching algorithm," it is used by keystore formats to protect against brute-force, dictionary, and rainbow table attacks on passphrase encryption, by repeatedly hashing the passphrase. Cryptographic hash function used in Ethereum.

Keccak was standardized as SHA A JSON-encoded file that contains a single randomly generated private key , encrypted by a passphrase for extra security. An area of development focused on layering improvements on top of the Ethereum protocol. These improvements are related to transaction speeds, cheaper transaction fees , and transaction privacy. An open source on-disk key-value store, implemented as a lightweight, single-purpose library , with bindings to many platforms. A special type of contract that has no payable functions, no fallback function, and no data storage.

Therefore, it cannot receive or hold ether, or store data. A library serves as previously deployed code that other contracts can call for read-only computation. An Ethereum client that does not store a local copy of the blockchain , or validate blocks and transactions. It offers the functions of a wallet and can create and broadcast transactions. The fork-choice algorithm used by Ethereum's consensus clients to identify the head of the chain.

Short for "main network," this is the main public Ethereum blockchain. Real ETH, real value, and real consequences. Also known as layer 1 when discussing layer 2 scaling solutions. Also, see testnet. A data structure used in Ethereum to efficiently store key-value pairs. An internal transaction that is never serialized and only sent within the EVM.

The act of passing a message from one account to another. If the destination account is associated with EVM code, then the VM will be started with the state of that object and the message acted upon. The third development stage of Ethereum, launched in October A network node that finds valid proof-of-work for new blocks, by repeated pass hashing see Ethash. Minting is the process of creating new tokens and bringing them into circulation so that they can be used.

It's a decentralized mechanism to create a new token without the involvement of the central authority. Referring to the Ethereum network, a peer-to-peer network that propagates transactions and blocks to every Ethereum node network participant. Also known as a "deed," this is a token standard introduced by the ERC proposal. NFTs can represent ownership of digital or physical assets. A software client that participates in the network.

In cryptography, a value that can only be used once. There are two types of nonce used in Ethereum- an account nonce is a transaction counter in each account, which is used to prevent replay attacks; a proof-of-work nonce is the random value in a block that was used to satisfy the proof-of-work. When a miner finds a valid block , another miner may have published a competing block which is added to the tip of the blockchain first. This valid, but stale, block can be included by newer blocks as ommers and receive a partial block reward.

The term "ommer" is the preferred gender-neutral term for the sibling of a parent block, but this is also sometimes referred to as an "uncle". A rollup of transactions that use fraud proofs to offer increased layer 2 transaction throughput while using the security provided by Mainnet layer 1. Unlike Plasma , a similar layer 2 solution, Optimistic rollups can handle more complex transaction types — anything possible in the EVM. They do have latency issues compared to Zero-knowledge rollups because a transaction can be challenged via the fraud proof.

An oracle is a bridge between the blockchain and the real world. They act as on-chain APIs that can be queried for information and used in smart contracts. One of the most prominent interoperable implementations of the Ethereum client software. An off-chain scaling solution that uses fraud proofs , like Optimistic rollups. Plasma is limited to simple transactions like basic token transfers and swaps.

A secret number that allows Ethereum users to prove ownership of an account or contracts, by producing a digital signature see public key , address , ECDSA. A method by which a cryptocurrency blockchain protocol aims to achieve distributed consensus.

PoS asks users to prove ownership of a certain amount of cryptocurrency their "stake" in the network in order to be able to participate in the validation of transactions. A piece of data the proof that requires significant computation to find. In Ethereum, miners must find a numeric solution to the Ethash algorithm that meets a network-wide difficulty target.

A number, derived via a one-way function from a private key , which can be shared publicly and used by anyone to verify a digital signature made with the corresponding private key. Data returned by an Ethereum client to represent the result of a particular transaction , including a hash of the transaction, its block number, the amount of gas used, and, in case of deployment of a smart contract , the address of the contract.

An attack that consists of an attacker contract calling a victim contract function in such a way that during execution the victim calls the attacker contract again, recursively. This can result, for example, in the theft of funds by skipping parts of the victim contract that update balances or count withdrawal amounts. An amount of ether included in each new block as a reward by the network to the miner who found the proof-of-work solution.

An encoding standard designed by the Ethereum developers to encode and serialize objects data structures of arbitrary complexity and length. A type of layer 2 scaling solution that batches multiple transactions and submits them to the Ethereum main chain in a single transaction.

This allows for reductions in gas costs and increases in transaction throughput. There are Optimistic and Zero-knowledge rollups which use different security methods to offer these scalability gains. The stage of Ethereum development that initiated a set of scaling and sustainability upgrades, previously known as 'Ethereum 2. A proof-of-stake chain that is coordinated by the Beacon Chain and secured by validators.

There will be 64 added to the network as part of the shard chain upgrade. Shard chains will offer increased transaction throughput for Ethereum by providing additional data to layer 2 solutions like optimistic rollups and ZK-rollups. A scaling solution that uses a separate chain with different, often faster, consensus rules.

A bridge is needed to connect these sidechains to Mainnet. Rollups also use sidechains, but they operate in collaboration with Mainnet instead. A computer programming term that describes an object of which only a single instance can exist.

A period of time 12 seconds in which a new Beacon Chain and shard chain block can be proposed by a validator in the proof-of-stake system. A slot may be empty. A program that executes on the Ethereum computing infrastructure. Short for "succinct non-interactive argument of knowledge", a SNARK is a type of zero-knowledge proof.

The most popular and most frequently used language for Ethereum smart contracts. Created by Dr. Gavin Wood. EVM assembly language in a Solidity program. Solidity's support for inline assembly makes it easier to write certain operations. A hard fork of the Ethereum blockchain, which occurred at block 2,, to address more denial-of-service attack vectors and clear state see Tangerine Whistle.

Also, a replay attack protection mechanism see nonce. An ERC token with a value pegged to another asset's value. There are stablecoins backed by fiat currency like dollars, precious metals like gold, and other cryptocurrencies like Bitcoin. Depositing a quantity of ether your stake to become a validator and secure the network. A validator checks transactions and proposes blocks under a proof-of-stake consensus model.

Staking gives you an economic incentive to act in the best interests of the network. You'll get rewards for carrying out your validator duties, but lose varying amounts of ETH if you don't. A layer 2 solution where a channel is set up between participants, where they can transact freely and cheaply. Only a transaction to set up the channel and close the channel is sent to Mainnet. This allows for very high transaction throughput, but does rely on knowing number of participants up front and locking up of funds.

A supermajority vote is required for blocks to be finalized on the Beacon Chain. Their purpose is to add their signatures to valid block headers. Sync committees allow light clients to keep track of the head of the blockchain without having to access the entire validator set.

Short for "test network," a network used to simulate the behavior of the main Ethereum network see Mainnet. Introduced by ERC proposal, this provides a standardized smart contract structure for fungible tokens. Tokens from the same contract can be tracked, traded, and are interchangeable, unlike NFTs. Data committed to the Ethereum Blockchain signed by an originating account , targeting a specific address.

The transaction contains metadata such as the gas limit for that transaction. A fee you need to pay whenever you use the Ethereum network. Examples include sending funds from your wallet or a dapp interaction, like swapping tokens or buying a collectible. You can think of this like a service charge. This fee will change based on how busy the network is. This is because miners , the people responsible for processing your transaction, are likely to prioritise transactions with higher fees — so congestion forces the price up.

At a technical level, your transaction fee relates to how much gas your transaction requires. Reducing transaction fees is a subject of intense interest right now. See Layer 2. A concept named after English mathematician and computer scientist Alan Turing- a system of data-manipulation rules such as a computer's instruction set, a programming language, or a cellular automaton is said to be "Turing complete" or "computationally universal" if it can be used to simulate any Turing machine.

A node in a proof-of-stake system responsible for storing data, processing transactions, and adding new blocks to the blockchain. To active validator software, you need to be able to stake 32 ETH. The transaction computation is done off-chain and then supplied to the main chain with a proof of their validity. Some rollups use fraud proofs. An off-chain solution that uses validity proofs to improve transaction throughput. Unlike Zero-knowledge rollups , Validium data isn't stored on layer 1 Mainnet.

A high-level programming language with Python-like syntax. Intended to get closer to a pure functional language. Created by Vitalik Buterin. Software that holds private keys. Used to access and control Ethereum accounts and interact with smart contracts. Keys need not be stored in a wallet, and can instead be retrieved from offline storage i. Despite the name, wallets never store the actual coins or tokens. The third version of the web. First proposed by Dr.

Gavin Wood, Web3 represents a new vision and focus for web applications- from centrally owned and managed applications, to applications built on decentralized protocols see Dapp. The smallest denomination of ether. A special Ethereum address, composed entirely of zeros, that is specified as the destination address of a contract creation transaction.

A zero-knowledge proof is a cryptographic method that allows an individual to prove that a statement is true without conveying any additional information. A rollup of transactions that use validity proofs to offer increased layer 2 transaction throughput while using the security provided by Mainnet layer 1.

Although they can't handle complex transaction types, like Optimistic rollups , they don't have latency issues because transactions are provably valid when submitted.
