Infrastructure choices

Website

Our website is build using Next.JS technology. It is a semi-decentralised application with an authentication based on data signature handshake. All wallet interactions are handled using the cardano-serialisation-lib. It is hosted on AWS using EC2 instances and load balancers.

Data storage

NFT metadata are directly stored on chain, in minting transactions metadata, and NFT images on IPFS. When syncronising on chain metadata with in game data, NFTs are burned and minted in a single multi-witness transaction.

Blockchain infrastructure

We are hosting multiple Cardano mainnet nodes running cardano-db-sync and Ogmios and diverse scripts such as Cadibot on dedicated servers (self hosting, Contabo, EC2).
