Servers use a per-server Unique Node List (UNL) to assess proposals. Default configurations rely on recommended lists published by Ripple and the XRP Ledger Foundation, although operators can choose other configurations. That means neither the network’s total validator count nor the label “decentralized” alone tells the whole story.
How does decentralization work on the XRP Ledger?
XRPL is a peer-to-peer network of independent servers. Some servers also send validation messages; those servers are validators. During consensus, each server considers proposals from the validators on its own UNL, then participants exchange proposals and work toward agreement on the transactions and their order for the next ledger version.
The UNL is configured per server, not a single universal list that every server must use. Recommended lists aim to give participants a trusted set with substantial overlap. That overlap matters: a server whose list has too little in common with other servers’ lists may reach a different view of the ledger.
XRPL’s Consensus Protocol documentation describes decentralized-system design as having no administrator who decides payment outcomes. That describes the protocol’s intended decision-making model; it does not mean every operational influence is evenly distributed or that the system has no dependencies.

What is a UNL?
UNL stands for Unique Node List. It is the set of validators a particular server trusts when evaluating proposals during consensus. A server bases its view on that trusted set rather than simply counting every validator that exists on the network.
As a result, two figures often treated as interchangeable are not: the number of validators across the network and the number on a given server’s UNL. The first does not tell you which validators a server relies on, how independently they are operated, or how much overlap exists among servers’ lists.

How many validators does XRPL have?
The XRPL FAQ, Answers to Your XRPL Questions, reports “150+ validators on the network” and “35+ on the default Unique Node List.” The surfaced FAQ text does not give an as-of date for those figures, so they should not be treated as an exact live count. Separately, the XRPL Negative UNL documentation reports 35 validators on the default UNLs as of June 25, 2024; that is a dated historical figure, not a current count.
A count alone cannot establish practical decentralization. XRPL operator guidance says validator lists should ideally include validators with different owners and from multiple legal jurisdictions and geographic areas. The cited official material does not provide a current quantified breakdown of validator ownership or jurisdiction, so those dimensions cannot be inferred from the published counts.
Can Ripple control the XRP Ledger?
Ripple publishes one recommended validator list, and the XRP Ledger Foundation publishes another. According to XRPL documentation, default server configurations trust validators on at least one of these recommended lists. Operators can configure a different list, but too little overlap with other servers’ lists can cause a server to diverge from the network’s view.
This gives Ripple influence over a recommended default; it does not, by itself, establish that Ripple alone controls consensus. The practical degree of concentration would also depend on current list membership, who operates the validators, and the configurations individual servers use. The official material cited here does not quantify those factors.

Who votes on XRPL amendments?
Amendments are the mechanism for changes that affect transaction processing. After an amendment’s code is included in a software release, validator operators vote through their server configurations. The documented process describes voting by trusted validators; it does not describe direct XRP-holder voting on protocol amendments.
An amendment must receive support from more than 80% of trusted validators for two weeks to become enabled. If support drops to 80% or less before activation, the two-week period restarts. Once enabled, an amendment remains in effect unless a later amendment changes that behavior. XRPL’s Amendments documentation states that amendments must maintain two weeks of support from more than 80% of trusted validators to be enabled.

What happens when validators disagree or go offline?
The standard quorum is 80% of a server’s trusted validators. XRPL’s Negative UNL mechanism can discount validators judged offline or malfunctioning when calculating quorum, helping the network make progress during partial outages. The quorum cannot fall below 60% of the configured list.
If enough validators are unavailable that servers cannot reach quorum, they may be unable to validate new ledgers even if they can still serve past or tentative data. This is a liveness trade-off: stopping confirmation can preserve agreement rather than allowing participants to finalize conflicting states.
What do XRPL’s security thresholds mean?
XRPL’s consensus documentation says consensus can continue unimpeded when fewer than 20% of trusted validators are faulty. It also says confirming an invalid transaction would require more than 80% of trusted validators to collude. These are documented protocol thresholds and assumptions, not a universal guarantee against every security, software, infrastructure, or governance risk.
What should you compare when judging decentralization?
For XRPL or any other ledger, a useful assessment looks beyond a headline validator count. Compare the same dimensions across networks:
