Fabric was the first blockchain implementation on Hyperledger. It has become the foundation for developing most blockchain applications. Fabric is unique within the blockchain ecosystem because it allows developers to use pieces of Fabric without committing to all the functionality — a truly tailored plug-and-play experience. Fabric also can create smart contracts called chaincode.

Fabric is a permissioned blockchain and does not utilize a cryptocurrency. This means that all the participants are known (as opposed to on a typical public blockchain where all the participants are anonymous by default). Fabric works like most blockchains in that it keeps a ledger of digital events. These events are structured as transactions and shared among the different participants. The transactions are executed without a cryptocurrency. (In contrast, a public blockchain uses its native cryptocurrency to pay the network to operate and to allow all the participants to remain anonymous.)

All transactions are secured, private, and confidential. Fabric preserves its integrity by only allowing updates by consensus of the participants. When records have been inputted, they can never be altered.

Fabric is an enterprise solution interested in scalability and complying with regulations. All participants must register proof of identity to membership services to gain access to the system. Fabric issues transactions with derived certificates that are unlinkable to the owning participant, thereby offering anonymity on the network. Also, the content of each transaction is encrypted to ensure that only the intended participants can see the content.

Fabric has a modular architecture. You can add or take away components by implementing its protocol specification. Its container technology can handle most of the mainstream languages for smart contract development.
