- Ethereum Foundation adds Erigon CTO Rebuffo for AI-focused client work — this brief
Giulio Rebuffo, formerly the chief technology officer of Erigon, has joined the 
Ethereum Foundation. Rebuffo announced the appointment on X on Friday, November 13, saying that his work at the foundation will combine applied AI with client development and involve collaboration with its technical teams.
The announcement marks a personnel move from a prominent Ethereum client project to the foundation. Cryptopolitan, the sole outlet covering the appointment, described Rebuffo’s new role as focused on applying AI to client development rather than presenting a specific product, funding commitment, or client release.
The broader crypto market was weak when the news was compiled. Ethereum was priced at $1,902.54, representing a 4.50% decline over 24 hours and a 13.94% fall over seven days. Its market capitalization stood at $232.48 billion. 
Bitcoin was also down 3.99% over 24 hours, while the total crypto market capitalization was $2.34 trillion and the Fear & Greed index registered 13, categorized as Extreme Fear.
The appointment is significant because it places Rebuffo, who previously held a technical leadership role at Erigon, within the foundation’s client-development efforts. The available coverage does not identify the AI methods, implementation timetable, or projects involved, leaving the practical scope of the role and its eventual effect on Ethereum tooling to be defined as the work progresses.
Since this brief published about 11 hours ago, Ethereum (ETH) has moved from $1,902.54 to $1,898.65 — -0.20%.

At today's peer-to-peer rate, 1 ETH ≈ ₦2.68M (about $1,898.65), down 1.3% over 24 hours. The naira itself trades about 4.2% above the official rate on the P2P market, so a Nigerian buyer's effective cost differs from the headline dollar price.
