Or Perelman

Held technical responsibility for delivering the protocol components that execute smart contracts, validate transactions and maintain node operation. Led the engineering teams that implemented the Rell runtime, database sharding model and the node software that realizes Chromia’s relational approach to DApps. Technical trade‑offs made under this leadership determined performance, fee mechanics and state model that directly affect CHR utility. Managed releases of core client software, testnets and mainnet upgrades, including bug fixes, benchmarking and interoperability components required for exchanges and custodians to integrate CHR. Those deliverables underpin the operational availability and security assumptions market participants rely on when listing, custodying or building on CHR. Also supervised developer SDKs, documentation and APIs that shaped onboarding flows and developer expectations. Choices about tooling, transaction models and RPC semantics influenced how applications consume CHR for payments, gas and fees and thus altered on‑chain demand patterns for the token.
