Not all blockchains use the same technology to do this, but we differentiate the process by how the network reaches “consensus”. They do so by contributing their computational power, which in return, is able to support the network. The blockchain is a community-based platform, meaning that in most cases, anybody can contribute to the network to help verify transactions. If that’s the case, how are transactions confirmed? This is where things get really interesting! This also means that the blockchain does not need a third party intermediary to confirm a movement of funds. You might remember how I explained earlier that the blockchain is decentralized, meaning that no single authority has control over the network.

So now that you understand where the blockchain definition comes from, the next part of my “What is blockchain” guide is to explain how transactions are confirmed!Ĭrypto Top 5 Best Bitcoin Mining Software Choices: Ins and Outsīitcoin mining software: all you need to know when choosing the best Bitcoin mining software that perfectly suits your needs! How are Transactions Confirmed on the Blockchain? As soon as it is confirmed, the transaction data is clear for everybody to see, which is why it is called a “chain” of transactions! This is the same for every single transaction. Every new or old box (transactions) that the container (block) carries will also be available to view on the public blockchain. However, the container is ready to depart for its next destination. That means the block has been confirmed and it is now available on the public ledger for all to see. To make things really easy for you, I am going to stick with the example of a container carrying boxes! Let’s imagine that the container has reached its first destination. So now you know what a block is, what about the chain?

The larger the block size limit, the more transactions it can hold. Every blockchain has its own maximum block size, which is normally the amount of data (megabytes) it can hold.īitcoin is able to hold the 1MB worth of data in each block, while others, such as Bitcoin Cash, have a block size limit of 8MB. Like in a real-world container, there is only a certain amount of transactions that the block can carry, which is determined by the maximum block size. I know this might sound complex, but stay with me as it is all about to make sense! So, in the example of the blockchain Bitcoin uses, it takes a total of 10 minutes for one block of transactions to be confirmed on the network. “The container carries lots of boxes” = The Block Carries Lots of Transactions In the world of cryptocurrency, the container is the “block” and each box that is on the container is an individual transaction. Think about a real-world container that carries lots of boxes from destination A to destination B. The easiest way to explain what it does is to split the word blockchain into two – block and chain! The next part of my “What is Blockchain” guide is going to talk about why it is called blockchain! Blockchain Definition: Why is it Called Blockchain?Īlthough there are now many different versions of the blockchain definition, they all work in very similar ways. There is so much to talk about when trying to understand the correct blockchain definition, so I thought it would be best to break everything down. However, as blockchains such as Bitcoin and Ethereum are public, anyone can view the transactional data. This is very similar to a real-world accounting ledger, where the company accountant can view every transaction that has ever occurred, along with account balances. That means that as soon as a transaction is processed and confirmed, it appears on the blockchain for all to see. The actual idea of blockchain technology is not only linked to financial transactions, as it has the potential to be applied to just about any industry!Īs the blockchain is decentralized, everybody has access to the same data (unless it is a private blockchain used by companies). Instead, transactions are verified and confirmed by the online community, which makes it decentralized! The protocol has lots and lots of benefits such as transparency, speed and security, which I will explain in more detail later on. The most interesting part to the blockchain is that no single person or authority has control over it.
