Hello, the little weekend experiment continuted - let’s (re)build the billion dollar ethereum world computer from scratch (zero) using a 25-year-old contract language - ruby :-) - and ye good 40-year-old SQL databases. What’s news? Use the new ActiveContract machinery to store the contract (world) state in the blockchain using - surprise, surprise - SQL database storage. See a first live converted gold mine / token contract in universum with SQL storage e.g. token_sql.rb. Let’s put ruby on the blockchain :-).
