Bio
John Adler is a Co-Founder of Celestia and former Chief Research Officer of Celestia Labs. He co-founded Celestia with Mustafa Al-Bassam and Ismail Khoffi after research and engineering work on layer-2 systems and rollups. His work is associated with modular blockchain architecture, data availability and rollup research.
Earlier official Celestia material listed Adler as Chief Research Officer; this profile marks that as former, as the current 2026 Celestia organizational structure should be verified against current first-party sources before adding any active operating title. Any current role — whether at Celestia Labs, the Foundation, another company or as an independent researcher — requires first-party verification.
Celestia launched mainnet in October 2023 with TIA as its native token. The 2026 Celestia roadmap focuses on custom high-performance chains and market infrastructure. Adler's specific contributions to this direction have not been independently attributed in current first-party sources as of August 2026. His co-founder status and historical research contributions are well-documented in the original Celestia seed round announcement and related publications.
