Technical details

• EAS - Projects, profiles, etc are all stored on-chain in Ethereum Attestation Service
• Batched requests with tRPC - Multiple requests are batched into one (for example when the frontend requests the metadata for 24 projects they are batched into 1 request)
• Server-side caching of requests to EAS and IPFS - Immediately returns the data without calling EAS and locally serving ipfs cids.
• SQL database for ballots - Votes are stored privately in a Postgres database
• Allo2 for token distribution - Payouts are calculated based on amount of configured tokens in the pool and the vote calculation
