Learn about core web3 development concepts including Ethereum, layer 2s, testnets, blockchain developer tools and more!
Explore the relationship of sharding, danksharding, and proto-danksharding, and how EIP-4844 and EIP-4488 will help Ethereum continue scaling.
Ropsten is deprecated by the Ethereum Foundation, and will no longer be supported by Alchemy on July 1st, 2022. Get free Goerli ETH and migrate from Ropsten to Goerli today.
A shadow fork is an intentional forking of a blockchain's mainnet or devnet to test synchronization assumptions in preparation for a network upgrade.
Learn about the Prater testnet, a Proof-of-Stake beacon chain, that will be merged with Goerli, a Proof-of-Authority Execution Layer (EL) testnet ahead of The Merge.
A reorg is caused when two blocks are published at the same time, from a bug, or a malicious attack which can lead to network issues and potentially a network failure.
Explore how the new ERC-4626 token standard enables Web3 developers creating DeFi applications to build tokenized vaults with increased composability and security.
A zero-knowledge Ethereum Virtual Machine (zkEVM) is a virtual machine that generates zero-knowledge proofs to verify the correctness of programs.
Create a private RPC endpoint for your personal use instead of using your web3 wallet's default RPC endpoint for faster speeds and more reliable service.
Archive nodes build archival blockchain data quickly and efficiently, and they’re useful for querying arbitrary historical data, like a user’s balances on a specific block.
Kiln and Kintsugi are two testnets that were shadow forks of the Ethereum mainnet used to prepare for the upcoming Merge.
Explore the leading ZK-rollup projects like dYdX and Sorare being built on today's top zk-rollup based layer 2 blockchains like StarkNet and zkSync.
The Sepolia testnet is a new Proof of Work (PoW) testnet to replace Ropsten. Learn what Sepolia is and how to get Sepolia ETH from a faucet.
Optimistic rollups are a leading Ethereum scaling solution. Explore how Optimistic rollups (ORUs) work, leading Optimistic rollup blockchains, bridges, and testnets.
The Ropsten testnet is a proof of work testnet on Ethereum that will be merged with the Ropsten beacon chain to test the upcoming merge to proof of stake.
Binaries are the raw data published via a smart contract to the Ethereum blockchain in bytecode, or long strings of hexadecimal characters. Learn about Solidity binaries.
Arbitrum is a leading Ethereum scaling solution that uses Optimistic Rollups (ORUs). Here are some important on-chain metrics so far in 2022.
