Rob Cunningham: If the World Could Choose Only One Blockchain

Rob Cunningham: If the World Could Choose Only One Blockchain

10-20-2026

On a go forward basis, “all things considered”, based on the comprehensive utility and liquidity needs of the entire world, “if” only one blockchain was allowed to exist, which should it be?

My choice: the XRP Ledger.

Under this hypothetical – one blockchain serving the world’s combined needs for payments, currencies, tokenized assets, exchange and settlement – XRPL offers the strongest fit in my judgment.

The deciding factor is its combination of financial functions:

• Move value: Fast settlement with low transaction costs.

• Represent value: Issue currencies, stablecoins and tokenized assets.

• Exchange value: A native decentralized exchange and automated market makers.

• Connect liquidity: XRP can bridge trading pairs when it provides a better execution path.

• Ripple adds institutional access through payments, custody, treasury management and prime brokerage.

• RLUSD supplies dollar-denominated liquidity within that broader offering.

• Those services strengthen the case for adoption; they remain distinct from the ledger itself.

One structural point: if only one blockchain existed, ILP would still help connect it to banks, mobile-money systems and other payment networks. Its purpose extends beyond connecting blockchains.

For the specific mission I describe – providing common financial infrastructure for a world of different assets, currencies and owners – I would select XRPL.

This is my judgment about best architectural fit in today’s world.
