David Schwartz, who served as Ripple's Chief Technology Officer for more than a decade before stepping down from his operational role on January 1, 2026, has publicly stated that only one person could convince him to return to full-time software development: former Ripple engineer Nik Bougalis.

In a post on X on July 23, 2026, Schwartz — who now holds the title of CTO Emeritus at Ripple — named Bougalis as the sole individual capable of persuading him to end his retirement from full-time engineering work. The remarks underscore the deep professional respect Schwartz retains for his former colleague. Schwartz is widely recognized as the principal architect of the XRP Ledger, having designed the consensus mechanism that powers one of the longest-running enterprise blockchain payment networks — making his endorsement of a fellow engineer particularly notable.

The one thing that could almost make me think seriously about unretiring would be getting to work with @nbougalis again.

Schwartz emphasized that neither financial incentives nor the scale of a given project would alter his decision. Instead, he pointed directly to Bougalis, delivering what stands as one of his strongest public endorsements of a former teammate.

Nik Bougalis: A Key Architect of the XRP Ledger

Bougalis joined Ripple as the company's eighth employee and spent nearly ten years leading engineering work on the XRP Ledger. During his tenure, he helped develop much of the network's core infrastructure and contributed to several technologies that shaped the blockchain's long-term direction. The XRP Ledger, which went live in 2012, remains one of the earliest distributed payment networks still in active operation.

Bougalis is also credited with three Ripple patents covering advanced cryptography — innovations that later became part of the technological foundation supporting the XRP Ledger.

Bougalis departed Ripple in 2022 and subsequently became Chief Technology Officer at the Algorand Foundation near the end of 2025. Algorand, a proof-of-stake blockchain founded by Turing Award–winning MIT professor Silvio Micali, also focuses on payments and enterprise financial infrastructure — meaning the two former collaborators now work within the same competitive segment of the layer-1 blockchain industry, albeit for different networks.

Schwartz's Limited but Ongoing Role at Ripple

Since retiring from full-time development, Schwartz has continued contributing to Ripple in a limited advisory capacity as CTO Emeritus. He remains involved in selected technical initiatives, including support for the XRPL 3.2.0 release earlier this year.

Despite this ongoing engagement, his latest statement makes clear that his days of writing code full-time are effectively over unless Bougalis becomes part of the equation. Schwartz noted that no other individual would be sufficient to draw him back.

The comments offer a rare glimpse into the professional relationships that helped shape the XRP Ledger during its formative years, and they reinforce the lasting influence Bougalis had on one of Ripple's most prominent engineers.

Schwartz has occasionally addressed his retirement with humor since stepping away from Ripple's daily operations. Earlier this year, he jokingly suggested that XRP's rally occurred because he retired. His latest remarks, however, carried a more reflective tone — centered not on market movements or competing networks, but on a single colleague whose engineering ability he considers uniquely irreplaceable.
