This article is a gentle introduction to blockchain technology and assumes minimal technical knowledge. It attempts to describe what it is rather than why should I care, which is something for a future post. So you want to use a blockchain for that? From the bag, you can take out different bricks and put them together in different ways to create different results. What’s the difference between a blockchain a a normal database? Very loosely, a blockchain system is a package which contains a normal database plus some software that adds new rows, validates that new rows conform to pre-agreed rules, and listens and broadcasts new rows to its peers across a network, ensuring that all peers have the same data in their databases. Relax these, and you don’t need many of the convoluted mechanisms of Bitcoin.
That said, let’s start with The Bitcoin Blockchain ecosystem, and then try to tease out the blockchain bit from the bitcoin bit. The Bitcoin Blockchain ecosystem acts like a network of replicated databases, each containing the same list of past bitcoin transactions. Each validator independently checks the payment and block data being passed around. There are rules in place to make the network operate as intended. The aim of bitcoin was to be decentralised, i. This has influenced how bitcoin has developed. Not all blockchain ecosystems need to have the same mechanisms, especially if participants can be identified and trusted to behave.
There is a big difference in what technologies you need, depending on whether you allow anyone to write to your blockchain, or known, vetted participants. Usually, when people talk about public blockchains, they mean anyone-can-write. These create cost and complexity to running this blockchain. You’ll behave because you’ve signed this piece of paper. This changes the technical decisions as to which bricks are used to build the solution.
