Blockchain is a shared, immutable ledger for recording the history of transactions. It fosters a new generation of transactional applications that establish trust, accountability and transparency.
IBM Blockchain has joined The Linux Foundation's Hyperledger Project to evolve and improve upon earlier forms of blockchain. Instead of having a blockchain that is reliant on the exchange of cryptocurrencies with anonymous users on a public network (e.g. Bitcoin), a blockchain for business provides a permissioned network, with known identities, without the need for cryptocurrencies.
Applying blockchain across industries and professions
Blockchain shows great promise across a wide range of business applications
For example, financial institutions can settle securities in minutes instead of days. Manufacturers can reduce product recalls by sharing production logs with original equipment manufacturers (OEMs) and regulators. Businesses of all types can more closely manage the flow of goods and related payments with greater speed and less risk.
Hyperledger Fabric is a blockchain framework implementation and one of the Hyperledger projects hosted by The Linux Foundation. Intended as a foundation for developing applications or solutions with a modular architecture, Hyperledger Fabric allows components, such as consensus and membership services, to be plug-and-play. Hyperledger Fabric leverages container technology to host smart contracts called “chaincode” that comprise the application logic of the system. Hyperledger Fabric was initially contributed by Digital Asset and IBM.
“Over the past two decades, the Internet has revolutionized many aspects of business and society–making individuals and organizations more productive. Yet the basic mechanics of how people and organizations execute transactions with one another have not been updated for the 21st century. Blockchain could bring to those processes the openness and efficiency we have come to expect in the Internet Era.”
