Tue, 31 Oct 2023 00:00:00 GMT https://ronan.eth.limo/blog/infinite-games/ https://ronan.eth.limo/blog/infinite-games/ On games that run and evolve independently of their creator. Why Infinite Games are more than on-chain games, how they relate to autonomous worlds, and what permission-less, persistent systems mean for game design. Fri, 19 Aug 2022 00:00:00 GMT https://ronan.eth.limo/blog/ethereum-gas-dangers/ https://ronan.eth.limo/blog/ethereum-gas-dangers/ How gas really behaves when a contract calls another contract, and why almost every smart contract account and meta-transaction implementation is vulnerable to malicious relayers. A close cousin of the infamous call depth attack, made easier by try/catch in Solidity 0.6.

If the verifier injects unforgeable data into the message, the user has nothing to verify, so sign-in can be seamless without sacrificing security.

Walking through a two-player card game to show why that worst case makes real-time games impossible with state channels alone. Thu, 09 Aug 2018 00:00:00 GMT https://ronan.eth.limo/blog/ethereum-session-accounts/ https://ronan.eth.limo/blog/ethereum-session-accounts/ How we removed nearly every transaction confirmation pop-up from a fully on-chain game by delegating moves to a short-lived, client-generated session account, pre-funded for its own gas and refunded at the end.
