This developer preview enables anyone to run the first blockchain ever to feature modular upgradeability and a microservice architecture! In fact, we will be using modular upgradeability over the coming months to iteratively add features to the developer preview (without a hardfork) like a consensus algorithm, token contract, and (of course) fee-less transactions, turning it into a full-fledged testnet right in front of your eyes!
The developer preview is essentially a way to run and test the Koinos blockchain framework, which means that it has the 6 critical microservices which can all communicate with one another to produce blocks, containing smart contracts, and then broadcast those blocks over a peer-to-peer network. Those microservices are; the mempool, jsonrpc, block producer, p2p, block store, and of course, the Koinos blockchain (koinos-chain).
