David Schwartz, Ripple’s CTO emeritus, drew attention on X after explaining the XRP Ledger through a poem rather than a standard technical post. What began as a reply to a user questioning the value of his “CTO emeritus” title turned into a broader statement about XRPL, blockchain infrastructure, and his own history in the sector.
A poetic breakdown of XRPL building blocks
According to the source material, Schwartz’s verse touched on several major parts of the digital asset market: payment rails, custody solutions, stablecoins, decentralized exchanges, automated market makers, and liquidity management. It also referenced the technical foundations behind those systems, including blockchain security and market infrastructure. The format was unusual. The subject matter was not.
The post also highlighted his familiarity with tokenization, derivatives, and other complex areas that usually appear in technical threads or conference panels, not in verse. That contrast is what made the message stand out across the XRP community.
Looking back to XRPL’s early development
Several lines reportedly reflected on Schwartz’s long involvement in crypto, including years spent explaining blockchain concepts, answering technical questions, and discussing practical uses for digital assets. The article also revisited the beginnings of the XRP Ledger: in 2011, Schwartz joined Jed McCaleb and Arthur Britto to build a blockchain network aimed at faster and more efficient payments while addressing limitations they saw in Bitcoin.
Their work led to the launch of the XRP Ledger in June 2012. The network later became one of the better-known blockchain platforms in the digital asset industry. Soon after launch, Schwartz, McCaleb, Britto, and Chris Larsen established NewCoin, which was later renamed OpenCoin and eventually became Ripple.
From Chief Cryptographer to CTO emeritus
Schwartz remained involved in Ripple’s technical direction over the years. He first served as Chief Cryptographer, then became Chief Technology Officer in 2018, taking part in multiple phases of XRPL development. The source says that in late 2025, he moved from the CTO role to CTO emeritus, while continuing to engage in discussions around XRP Ledger development, blockchain infrastructure, and new trends in the crypto market.
The post may have started as a social media rebuttal, but it ended up functioning as a compact account of Schwartz’s experience, his role in XRPL’s creation, and his technical range across payments, stablecoins, on-chain liquidity, and blockchain security.
