What is the XRP Ledger, and is it a real blockchain?

The full answer

What is the XRP Ledger?

XRPL.org describes the XRP Ledger as “a decentralized public Layer 1 blockchain for creating, transferring, and exchanging digital assets” [2]. Layer 1 means it is a base network with its own validators and its own native asset, XRP, rather than a system built on top of another chain. XRPL.org calls it “permissionless” [11]; accounts can send payments, issue tokens and trade them on trading infrastructure built into the ledger [2].

It is a blockchain in the usual sense: XRPL.org describes how the network “confirms new transactions and ledger versions, forming a blockchain” [3]. Where it differs from Bitcoin is in how the network reaches agreement, which the consensus section below covers.

How long has it run, and was it built for payments from the start?

The ledger first launched in June 2012 [1]. According to XRPL.org, its three builders, David Schwartz, Jed McCaleb and Arthur Britto, liked Bitcoin but “observed the waste inherent in mining” and aimed at a digital asset “built specifically for payments” [1]. XRPL.org also says XRP was “created in 2012 specifically for payments” [11]. These are the project’s own accounts of its intent as published on XRPL.org today, not design papers from 2012.

The payments focus shows in the features. The ledger has a built-in exchange, and XRPL.org says auto-bridging routes trades through XRP “when doing so is cheaper than trading directly” [7]. XRPL.org says transactions settle in 3 to 5 seconds for fractions of a cent [2]. What is switched on today and what is still in development is tracked in XRP Ledger features, live and coming.

How does it reach agreement without mining?

Each server chooses a set of validators it trusts, called its Unique Node List or UNL. When the validators agree on a new ledger version, that version is “considered validated, and final” [3]. XRPL.org says “confirming transactions does not require wasteful or competitive use of resources” and that consensus continues as long as fewer than 20% of trusted validators are faulty [3]. Changes to the rules need support from more than 80% of trusted validators for two weeks [5]. XRPL.org’s FAQ counts more than 150 validators on the network, and 35 on the default recommended list as of July 2023 [4]. The full mechanism is explained in how the XRP Ledger reaches consensus without mining.

How is the XRP Ledger different from Ethereum?

Ethereum describes itself as “a decentralized blockchain network and software development platform” built on “open-source programs called smart contracts” that “let anyone create their own digital assets and decentralized applications” [6]. Its validators lock up ether as a security deposit and “if they do it correctly, they earn ETH” [6]. XRP Ledger validators do not stake XRP; XRPL.org says running one “does not require any fees or XRP” [4]. XRPL.org presents the XRP Ledger’s built-in trading and APIs as a way to “skip complex smart contract development” [2]. In my reading, that makes common financial actions simpler and building arbitrary applications harder. Whether general-purpose chains could take over the bridge role is weighed in could Ethereum or Solana be the bridge. How much the ledger is used is covered in XRP Ledger activity numbers.

What supports calling its technical viability largely demonstrated, and what counts against it?

For: XRPL.org’s home page claims “14 Years +” of continuous uptime and more than 8 million funded accounts [2]. The ledger has run since June 2012 on a consensus design that does not use mining [1][3].

Against that, there are three items on the record. First, Decrypt reported that the ledger halted block production for about an hour on February 4, 2025, which sits uneasily with the “continuous uptime” claim. Schwartz said validations “were not being published, causing the network to drift apart”, and that no assets were at risk [8]. Second, Protos reported that headers for the first 32,569 ledgers from 2012 were lost to a bug that, according to Ripple founder Joel Katz, affected every server running at the time; ledger 32,570 on January 1, 2013 is the first fully verifiable one [9]. Protos argues that the public “cannot reconstruct the data within 534 transactions” and that users today “must trust the statements of people who were operating the Ripple network in 2012” [9]. Third is the question of who picks the validators: xora.finance reported that its August 24, 2026 snapshot found the recommended lists published by Ripple and by the XRP Ledger Foundation contained the same 35 validator keys [10]. That concentration is the subject of the validator centralization critique.

On this page’s reading, the record supports the claim that the ledger works as a payment and exchange system at its current scale. It does not by itself show that banks use it, which is a separate question.
