Ontrak ONSTAK Certified-Blockchain-Essentials-16Hrs


A blockchain is a public ledger of all bitcoin transactions that have ever been executed. A block is the “current” part of a blockchain which records some or all of the recent transactions and once completed, goes into the blockchain as permanent database. Each time a block gets completed, a new block is generated. Blocks are linked to each other (like a chain) in proper linear, chronological order with every block containing a hash of the previous block. This training covers basic concepts of blockchain and no programming skills are required. You must understand basic software object-oriented programming and how to use the command line. When you complete the training, you should understand what a blockchain business network is, how to build a model and simple blockchain solution and the role of the developer in creating blockchain applications.
