Welcome to the Blockchain Academy
Training and consulting on blockchain and cryptocurrencies in South Africa and various other countries. We train attendees about the opportunities that exist and how to use this technology in order to innovate and better prepare for the future.
Our next course is the Bitcoin and Blockchain Beginner Course being held in Johannesburg on twelve September 2017.
The outcome of this course is to provide individuals with a general overview of bitcoin and the blockchain. Attendees will learn more about what bitcoin is, its history, how to use bitcoin: storing bitcoin in a wallet, buying and selling bitcoin on an online exchange, as well as sending and receiving bitcoin from one person to another without the need for a trusted third party.
The course also provides an overview of the blockchain: how transactions are stored on the blockchain, how mining works through consensus, the differences inbetween permissioned and permissionless blockchains and why these differences are significant.
The course further explains current use cases and opportunities this technology provides in terms of include clever contracts, payment rails, immutable ledger, proof of ownership, remittances and micro-transactions. It also discusses alternatives to bitcoin and the bitcoin blockchain.
The course touches on current regulation and compliance globally and in South Africa.
