DollaMay 2019 - Présent
Business Context
‣ 6 employees - 3 software engineers
‣ Organisation Fully Remote
Dolla aims to become a Consortium Blockchain with the following characteristics :
‣ High transactional volumes (10k transactions/s)
‣ Latencies (< 5s )
‣ Based on Democratic Byzantine Fault Tolerance (DBFT) consensus algorithm (No PoW or PoS,)
‣ Weak coordinator
‣ Partial synchrony in the voting phase
‣ Transaction finality, Once the consortium reaches a consensus, the decision is not reversible
‣ Energy efficiency, DBFT can achieve a distributed consensus without carrying out complex
mathematical computations (like in PoW)
Our efforts have been essentially put on the consensus platform development :
‣ Proof of Concept
‣ Proof of Design
‣ Performance optimisation
A substantial part of our codebase have been open sourced with more detailed documentation. I invite you to have a look as it demonstrates my abilities in Haskell and my current knowledge in general (see Dolla Github Repository link below)
‣ Consensus Architecture, CQRS, Domain Driven Design (DDD) , SAGA
‣ Functional Programming (FP), Streaming (FRP)
‣ Stack : Haskell, Streamly, EventStore
