Hyperledger Fabric is an enterprise-grade, distributed ledger platform that offers modularity and versatility for a broad set of industry use cases. Rather than a permission-less system where anyone can transact and access data, Fabric offers a permissioned, secure, and scalable platform that supports smart contracts and data privacy. This architecture allows for solutions developed with Fabric to be adapted for any industry, thus ushering in a new era of trust, transparency, and accountability for businesses.
Fabric provides a spectrum of options to support transaction and data privacy. You can use separate “channels” if you need total transaction isolation between member organizations. And you can use “private data” within a channel if you’d like to keep data private while writing hashes on a shared ledger as transaction evidence. Private data can be shared on a need-to-know basis and then verified against the on-chain hash evidence.
