- According to Ripple’s CTO David Schwartz, the new XRPL update is a revolutionary that further expands network decentralization.
- For now the update is only available in the Rippled 1.6.0 test network and is still being checked for bugs.
According to Ripple’s CTO David Schwartz, the latest XRPL update is a groundbreaking game. Explain that each server in the XRPL has a so-called “Unique Node List” (UNL) which contains all participating validators.
By the way, this feature will be a huge game changer for the UNL evolution of XRPL: https://t.co/oxCmRQllGY

The update mainly affects offline or malfunctioning validators due to external circumstances such as hardware maintenance, Internet problems or attacks:
The “Negative UNL” is a list of trusted validators that are believed to be offline or malfunctioning, as stated by a consensus of the remaining validators. Validators in the negative UNL are ignored to determine if a new ledger version has reached a consensus.
According to Schwartz, the update is currently still being checked for further errors in the Rippled 1.6.0 test network and is not yet available live. The update simplifies the search for validators based on a complex list of selection criteria and their connection to the network:
When choosing a validator, performance is not the only criterion. Expertise, institutional commitment, network redundancy, network commitment and many other factors must come into this.
The biggest benefit of the UNL’s negative proposal is that it will make it much easier to say “yes” to more different validators, even if they work on a single residential connection with a tiny machine in someone’s living room.
Furthermore, the risk of integrating new validators with the network can be drastically reduced. If more than 20% of trusted validators go offline or can no longer communicate with the rest of the network, the network stops validating new ledgers because it cannot reach a quorum.
In special cases, when validators go offline once or twice, the remaining validators can use the UNL to incrementally adjust their actual UNLs so that the network only needs 80% of the online validators to reach a quorum. However, to avoid network fragmentation, the quorum has a minimum of 60% of all validators participating in the network.
The new functionality can be tested as follows:
Negative UNL functionality is currently available for testing on Devnet. You can test negative UNL functionality by adding or modifying a file [features]in the rippled.cfg file, as described in Connect your rippled to a parallel network.
The new update will also improve decentralization without sacrificing XRP Ledger’s performance, Schwartz said. More information is available on the official website.
Ripple joins Civic Alliance
As we reported yesterday, Ripple has joined the Civic Alliance. The body works to promote democracy and fair elections in the United States of America by encouraging the impartial participation of voters. The consortium includes other tech giants like Microsoft, Amazon, PayPal, and Reddit.
