In LevelDB and CouchDB, we see an important aspect of Hyperledger Fabric – it is pluggable. The world state database could be a relational data store, or a graph store, or a temporal database. This provides great flexibility in the types of ledger states that can be efficiently accessed, allowing Hyperledger Fabric to address many different types of problems.

Its modular and versatile design satisfies a broad range of industry use cases. It offers a unique approach to consensus that enables performance at scale while preserving privacy. - hyperledger/fabric Hyperledger Fabric: Fabric is the most popular Hyperledger framework. Smart contracts (also known as chaincode ) are written in Golang and JavaScript, and run in Docker containers. Fabric is known for its extensibility and allows enterprises to build distributed ledger networks on top of an established and successful architecture. v.

Oct 18, 2020 What is chaincode?¶ Chaincode is a piece of code that is written in one of the supported languages such as Go or Java. It is installed and instantiated through an SDK or CLI onto a network of Hyperledger Fabric peer nodes, enabling interaction with that network’s shared ledger. Chaincode runs in a secured Docker container isolated from the endorsing peer process. Chaincode initializes and manages the ledger state through transactions submitted by applications.

In Hyperledger Fabric, a ledger consists of two distinct, though related, parts – a world state and a blockchain. Each of these represents a set of facts about a set of business objects. Firstly, there’s a world state – a database that holds current values of a set of ledger states.
