Understanding Hyperledger Fabric
1.4 release, long term support, Raft consensus differs from Kafka, which is complex and event based, fairly easy to migrate from Kafka to Raft
What distinguishes Fabric from other frameworks?
It's permissioned, as in everyone in the network is identified, unlike public where you don't know who you're transacting with.
Pluggable consensus, currently using elliptic curve libraries, if you want to deploy fabric in china or russia they have different standards and so you need to be able to plug in different libraries
Supports smart contracts, write in general purpose language, don't need to know solidity or viper, can be java, go, javascript
Support privacy, public networks have anonymity but not privacy. dont want to put all your data for a tx on blockchain itself anyways
no mining, no native cryptocurrency, there is active work to introduce it "FabToken"–leads to less risk and less cost to running technology and nodes
Key advantage is scalability because you don't have to execute every tx on every node
Public network have to treat every entity as adversarial because there is no trust, hence need order-execute model
Permissioned system, create a consortium or some closed network of participants, can vet identities, typically have a certificate of authority to identify who they are. There's a shared governance model.
Public: no governance, it's just the software, no dispute resolution authority
