Hyperledger (or the Hyperledger Project) is an umbrella project of open source blockchains and related tools that the Linux Foundation [1] started in December 2015. IBM, Intel, and SAP Ariba have contributed to support the collaborative development of blockchain-based distributed ledgers. It was renamed the Hyperledger Foundation in October 2021.
This is a list of free and open-source software (FOSS) packages, computer software licensed under free software licenses and open-source licenses.Software that fits the Free Software Definition may be more appropriately called free software; the GNU project in particular objects to their works being referred to as open-source.

The software validates the entire blockchain, which includes all bitcoin transactions ever.

All of this information is then recorded onto the public and immutable blockchain based on Hyperledger Besu—an open-source, Ethereum-compatible framework provided by the Linux foundation.
IOTA is an open-source distributed ledger and cryptocurrency designed for the Internet of things (IoT). [1] It uses a directed acyclic graph to store transactions on its ledger, motivated by a potentially higher scalability over blockchain based distributed ledgers. [2]
DApps also have a public, decentralised blockchain that is used by the application to keep a cryptographic record of data, including historical transactions. [3] Although traditional DApps are typically open-source, DApps that are fully closed-source and partially closed-source have emerged as the cryptocurrency industry evolves.
OpenTimestamps (OTS) is an open-source [2] project that aims to provide a standard format for blockchain timestamping. [3] With the advent of systems like Bitcoin, it is possible to create and verify proofs of existence of documents (timestamps) without relying on a trusted third party; this represents an enhancement in terms of security, since it excludes the possibility of a malicious (or ...
