Be introduced to cryptocurrencies
There are thousands of cryptocurrencies in existence. On this course, you will learn how to develop programs to send and receive payments for BTC, ETH, and XRP.
Importantly, you will also learn about the groundbreaking distributed ledger technology that these cryptocurrencies are built on.

Learn how to build programs that interact with distributed ledger technology
Applications built on distributed ledger technologies (DLTs) are more transparent, promote decentralised control, and are more resilient to software crashes as well as malicious actors.
On this course, you’ll gain the skills needed to create your own applications and programs that can interact with and be built on DLTs.

Study with the specialists at King’s College London and Quant Network
The King’s College Department of Informatics has a long-established leadership in the Distributed Artificial Intelligence domain, which is closely related to blockchain.
Coupled with the DLT know-how of Quant Network, these experts are the perfect guides to help you become a blockchain developer.
