XRPL Governance Layer Ensures Protocol Legitimacy through Validator Agreement

The XRP Ledger (XRPL) has undergone a significant upgrade with the activation of fixCleanup3_1__3 on May 27. While this maintenance event may seem routine, it reveals the intricacies of XRPL's governance layer and how it ensures protocol legitimacy.

Beyond the technical fixes addressed by the upgrade, such as improvements to NFTs, Permissioned Domains, Vaults, and the Lending Protocol, XRPL co-creator David Schwartz shed light on the process of a potential fork. He emphasized that raw node count is an inadequate proxy for consensus power, highlighting the limitations of a system where nodes vote in proportion to their number.

Schwartz explained that in XRPL, each server operator maintains a curated set of validators they trust not to collude, known as the Unique Node List (UNL). This UNL determines which validation votes are counted during consensus, ensuring that only trusted validators contribute to the ledger's integrity. The amendment process requires support from more than 80% of these trusted validators for two weeks before new rules become permanent.
