sub0 Asia 2024 - Luis Ramirez (Gear Foundation)
summary
Gear Protocol on Vara/Bar Network runs WASM smart contracts with Rust and AssemblyScript APIs, an actor model and per-contract persistent memory; templates (ERC20/721) speed development. The demo builds a Battleship dApp that funds a payless voucher with 42 BAR so players with zero balance can transact while the voucher pays gas, and it uses signless sessions (temporary keypair, configurable timeout and limited actions) so users don’t re-sign every move. Delay messages for on‑chain timers are also implemented and the demo works as shown.
