XRPL's May 27 Upgrade Reveals How Validators and Markets Actually Decide a Blockchain Split

XRPL's May 27 activation of fixCleanup3_1_3 is, on its face, a routine maintenance upgrade — version 3.1.3 of rippled bundles fixes for NFTs, Permissioned Domains, Vaults, and the Lending Protocol, with the default validator vote set to Yes. The amendment clears the 80%-for-two-weeks threshold required to become permanent, and infrastructure operators still running pre-3.1.3 nodes become amendment-blocked at activation, losing the ability to submit transactions, participate in consensus, or vote on future amendments.

XRPL co-creator David Schwartz used the moment to explain what a genuine fork would actually demand: not just unupgraded nodes, but old-rule validators, a competing Unique Node List, old-rule code distributions, and infrastructure and market recognition sufficient to make the rival ledger tradable.
