The XRP Ledger uses a consensus algorithm to resolve the double spend problem and choose which transactions to execute in which order. Consensus also governs rules of transaction processing.
Understand the role of consensus in the XRP Ledger.
The rules and principles of the consensus algorithm that allow users to transfer funds (including fiat currencies, digital currencies and other forms of value) across national boundaries as seamlessly as sending an email.
Learn how the XRP Ledger Consensus Protocol is protected against various problems and attacks that may occur in a decentralized financial system.
Understand how transactions can be queued before reaching consensus.
Understand when and how it's possible to cancel a transaction that has already been sent.
Be aware of ways transactions could be changed to have a different hash than expected.
Amendments represent new features or other changes to transaction processing. Validators coordinate through consensus to apply these upgrades to the XRP Ledger in an orderly fashion.
How validators vote on fees (transaction cost and reserve requirements).
Scholarly articles on consensus algorithms and related research.
Understand how test networks and alternate ledger chains relate to the production XRP Ledger.
