Please navigate to the white paper section of the website (link below) and download “Blockchain and Ledgers and Cryptos – Oh My! ” Here is the abstract:
The basic concepts behind blockchain are relatively straightforward: a distributed database (the “ledger”) that maintains a complete transaction history on multiple nodes of a network. Confusingly, much that has been written about blockchain conflates this simple concept with the applications of blockchain to things like cryptocurrencies (Bitcoin, Ethereum, Ripple etc.), smart contracts, trans-border payments, and securities settlements. In this article, we will try to clarify the differences and provide a high-level understanding of how blockchain works.
