Block TimeWhat Is Block Time?Block time is the measure of the time it takes the miners or validators within a network to verify transactions within one block and produce a new block in that blockchain. Show
Blockchains were first popularized by Bitcoin when it was introduced in 2009. The technology has grown as more cryptocurrencies are created, each of which can use different or the same blockchain, validation methods, and techniques for creating new blocks. Key Takeaways
Understanding Block TimeA blockchain is a distributed database that records all transactions within a cryptocurrency network. You can think of a block within the database as a cell in a spreadsheet where transaction information is stored. Miners verify the transactions, which takes time because finding the solution to the block requires the computers to make a vast amount of trial and error calculations.
This is called hashingusing an algorithm to verify all the transactions within a block, which validates the authenticity of the transactions and stored information. When the block solution is found, a new block is created. The amount of time to find the solution and create a new block is the block time. Here are a few key points to remember if you're trying to understand block time:
How Is Bitcoins Block Time Different Than Ethereum's?Each cryptocurrency has a different block timeBitcoin takes around 10 minutes, while Ethereum only takes around 14 seconds. The exact amount of time it takes for block generation varies and depends on the difficulty of the hash (the hexadecimal number generated by the hashing algorithm). In other words, block times will not always be the same. Consensus mechanisms exist to allow a network to agree that a transaction is valid. Cryptocurrencies can use different consensus mechanisms, which, among other factors, affect the time it takes to verify transactions and create new blocks. Proof-of-work and proof-of-stake are two types of consensus mechanisms that use different methods for verifying a transaction. Ethereum is transitioning to a proof-of-stake consensus mechanism throughout 2022, while Bitcoin remains on the more popular and energy-intensive proof-of-work mechanism. How Many Bitcoins Will Ever Be Created?Bitcoin has a limit of 21 million. There are nearly 19 million Bitcoins in circulation, and the number of Bitcoins created per year halves every four years. This slows down Bitcoin creation. How Many Ethereum Will Ever Be Created?Ethereum, unlike Bitcoin, doesn't have an upper limit on the number of coins that will be created. How Do I Get a Bitcoin Block?You never actually receive a Bitcoin block since it is part of Bitcoin's framework. Instead, you receive a Bitcoin when your miner solves the hash and creates another block.
