Ripple’s Fast Settlement Solution

Ripple offered one of the fastest settlement chains, known as the XRP Ledger or XRPL. The ledger aims to compete for scalability and liquidity with Ethereum’s L2 ecosystem, based on settlement speed and the low cost of transactions.

Both solutions offer a similar range of transactions per second, but XRPL has a native finality process, instead of relying on Ethereum. This guide covers the key differences between the XRP Ledger and Ethereum Layer 2s, highlighting the strengths and weaknesses for different types of chains.

Why Settlement Speed Matters

Payments vs Smart Contracts vs Rollup Settlement

Settlement speed, also known as finality, is a key component that may define a network’s use cases. XRPL settles transactions to finality in 3-5 seconds, which is standard for most chains.

There is no preview period or waiting time. When comparing Ethereum L2 rollups, all chains have a different time to finality. Those L2 still need to wait for an Ethereum block to make a permanent, secured record.

Payments in crypto can be relatively simple, but smart contract activity creates complexity. Without instant settlement, there are fears of delays or potential exploits.

Rollups also have a relatively long time until final settlement, creating delays in app usage. Rollups can take minutes or even hours until locking in their finality.

Growing Institutional Interest in Fast Finality

Institutional finance that uses blockchains is showing concerns about finality. Earlier crypto stages caused days-long delays to ensure transactions are irreversible, for instance, by waiting for multiple node confirmations.

The settlement and finality process can take minutes and cause significant delays in trading and app usage. Fast finality aims to achieve a process that is fair and tamper-proof, but also fast. The biggest challenge is to achieve reliable, fast node consensus without sacrificing security.

Use Cases That Require Instant Settlement

Instant settlement can improve the quality of apps using some form of on-chain payment. Those include direct remittances, trading and on-chain swaps, treasury management, and more.

Apps with an on-chain component aim to achieve the speeds that regular users expect from their fintech tools, hence the need for fast settlement and no waiting period until finality.

Users may also want to use their funds quickly, instead of seeing their transaction locked in a transitory state until finality is achieved.

XRPL Overview: A Purpose-Built Settlement Layer

XRPL is a dedicated settlement layer for both native transactions and connections to other chains. Transactions are validated by a network of permissionless, voluntarily run nodes, which achieve consensus via Unique Node Lists, which contain already vetted validator nodes.

Consensus Model

Ripple built XRPL to have a unique consensus model, which combines a mix of permissionless validators and vetted nodes. Transactions are finalized with the help of Unique Node Lists, where existing nodes are vetted and gain a reputation for reliability. The network thus has a layer of trust and relies on the list mechanism to exclude bad actors.

3-5 Second Finality

XRPL achieves 3-5 seconds for its finality, based on the confidence in the UNLs. To compare, widely used chains like Arbitrum can reach up to 17 minutes until finality, with 18 minutes for other major L2 solutions. L2 chains usually have a longer time to finality, as they wait to secure their ledger through Ethereum blocks.

Since some chains pay for space in those blocks, they post more rarely, stretching the time to finality. Other chains create a workaround with soft and hard finality, but the process is also slower. For XRPL, finality relies on the chain’s own validators and faces no additional delays.

Low Fees and Deterministic Settlement

The XRPL architecture and validator mix mean the network offers extremely low fees. The usual fee is less than $0.00001. The network has taken into consideration demand from institutions, which prefer fast final settlement, not subject to reversal.

Some of the common chains rely on probabilistic settlement, where the finality is achieved via multiple confirmations. XRPL uses deterministic settlement, meaning the state of the transaction is not even hypothetically reversible once it is finalized.

Why XRPL Doesn’t Rely on Miners/Validators for Block Production

XRPL has abandoned mining in a bid to build a cheaper, yet secure network. The chain also does not use validators, which can also skew the incentive ecosystem or become overly influential. Instead, the chain uses nodes, which are vetted into Unique Node Lists. XRPL also aims to make the network more predictable, which would be impossible with the presence of overly influential miners or validators.

XRPL’s Core Design: Payments + Liquidity Layers

XRPL is not only used to settle payments, but also provides reserves of liquidity. The chain not only offers simple settlement, but also aims to offer specific tasks that closely track the practices of traditional finance.

XRPL can handle simple XRP transfers, in addition to cross-currency payments, by connecting senders and receivers through orders. Transactions on XRPL can be complex, combining multiple paths and liquidity sources to deliver the desired end balance.

Built-in Features: DEX, IOUs, Escrow

The potential for complex transactions means XRPL contains some features that are only possible as separate apps on other chains. XRPL has a built-in DEX for swaps between various assets. The chain can carry tokenized IOUs between two counterparties. Currently, XRPL is holding a vote on launching an escrow service.

The XRPL decentralized ledger is thus one of the oldest platforms for built-in blockchain swaps, even before the creation of the first decentralized exchanges with automated liquidity.

Ethereum Layer 2s Overview: Scaling via Rollups

Ethereum has successfully scaled through L2 chains, of which the usage of rollups is the most common type of chain. L2 chains perform a part of their computation offline, later recording the state of the ledger on Ethereum.

Optimistic Rollups

Optimistic rollups use a process where they accept all proposed transactions as valid (optimistic) and rely on fraud proofs, where network participants can challenge the validity of transactions before they reach finality. Usually, those networks have a 7-day challenge window. While transactions are executed instantly, their settlement is delayed for verification and is open to challenges.

zk-Rollups

Zero-knowledge, or ZK rollups, make a different assumption about the validity of transactions. All transactions are processed entirely off-chain, but then for each block, a zero-knowledge proof is created for the batch of transactions in that block. The ZK-Rollup chain then posts the proof with minimal additional data to the main network.

The ZK-Rollup scaling solution offers more reliable mathematical proofs and can achieve faster finality safely. However, it relies on more computation from nodes to produce the validity proof after checking transactions.

Major L2 Solutions

One of the most widely used Optimistic Rollup networks was launched by a major compliance-focused platform. The network relies on speed, with fast transaction processing, but a finality time of 13 to 19 minutes. The goal is to offer compliant on-chain activity with extremely low fees. It is one of the networks that spends the most fees for posting its state on Ethereum when transactions achieve finality.

Shared Themes

L2 chains are all capable of near-instant transaction processing, with no delays for confirmations. However, each L2 chooses an interval at which to post the state of its ledger and include it in an Ethereum block. If too many L2 post their state, the fees to post increase.

There are two ways to post the latest state on Ethereum: calldata or blobs. Both methods require more gas if a larger number of L2 decide to post. In late 2025, Ethereum increased the blobs per block from 6 to 10, giving more leeway to L2 chains to post their ledger without additional fees.

Ethereum updates have decreased posting fees from hundreds of thousands of dollars to a few thousand dollars per day, even for regular blob usage.

Key Takeaways

Both XRPL and Ethereum L2 solutions offer compelling approaches to settlement speed and scalability. XRPL prioritizes deterministic, fast finality with a purpose-built architecture, while Ethereum L2s leverage the security of the main chain through rollup technology. The choice between them depends on specific use cases, institutional requirements, and preferences for settlement guarantees.
