Daniel Ellison is Co-Founder and Chief Research Scientist of OpenESG.com - the world’s sustainability data infrastructure.  

has been a software developer for several decades. He started his career as a graphic designer but eventually transitioned to software development full time. He has worked at many companies over the years. Daniel started a Canadian company with three other people back in the late '90s. He served as the company's CTO and was responsible for all technical decisions and hiring. The company grew quickly to 50 employees, at which point it was acquired by an American company.

Daniel discovered Ethereum around the time of the Frontier launch. Quickly realizing its potential he sought out the Ethereum core developer community and started participating. Daniel and Nick Johnson worked on the beginnings of the Ethereum Name Service (ENS). The original ENS registry contract deployed to mainnet was written by Daniel in a language called LLL, due to its efficiency and small binary size.

Daniel continued his new career in the Ethereum ecosystem when he was invited to join ConsenSys in Joe Lubin's Special Projects group. There he maintained the LLL language and started mentoring and guiding the ConsenSys developers. He also conceived and executed a hardware project to create an inexpensive personal Ethereum node.

Daniel enjoys music and dogs.
