I think for many people out there, Blockchain is this phenomenon, which is hard to get your head around. I started watching videos and reading articles, but for me personally, it wasn’t until I wrote my own simple Blockchain, that I truly understood what it is and the potential applications for it. The Blockchain technology can sound very abstract, but in the end a Blockchain is just a distributed data storage. So the same copy off the data is kept on multiple machines which are connected and each data storage, so on a machine, the Blockchain is just a chain, a list of data stores (containers); the so-called blocks, which are in turn Files for blockchain-certificates, version 2.1.6; Filename, size File type Python version Upload date Hashes; Filename, size blockchain_certificates-2.1.6-py3-none-any.whl (32.3 kB) File type Wheel Python version py3 Upload date Feb 17, 2021 May 24, 2020 · Blockchain technology is an innovative application of the distributed ledger to create a network of connected nodes.
