Allen Shkair — Founder / Lead Developer, ACT Blockchain
Allen Shkair is a Protocol Architect and Deterministic Systems Engineer based in Bordeaux, France, with over a decade of experience in blockchain infrastructure, consensus design, financial systems, and distributed computing. He is the founder and lead developer of ACT Blockchain, a compliance-native Layer 1 protocol that embeds identity verification, compliance rules, and jurisdictional logic directly into its consensus and execution layers. His core stack is Rust, Solidity, and WASM.
