Featured Technology
Hyperledger Fabric*
The number one enterprise blockchain technology since it was created. Build production‑grade networks with privacy and proven tooling.
* Hyperledger Fabric is the leading open‑source framework for building private, permissioned distributed ledger technology (DLT). The project is hosted by the Linux Foundation.
Proven in production
What are some key Hyperledger Fabric case studies?
Privacy by design
Governance you can enforce
BFT available
No native token
Open, portable, production‑ready
Channels and Private Data Collections
Partition data by business context and share only on a need‑to‑know basis. Keep auditability through on‑chain hashes.
Smart contracts, your way
Write chaincode in Go, Node.js, or Java. Choose key‑value or JSON models, and use CouchDB for rich JSON queries when needed.
Simplified client development with Fabric Gateway
Fabric v3 adds a production Byzantine Fault Tolerant ordering service based on SmartBFT for networks that require resilience to malicious faults.
State and query options
Default LevelDB for speed, CouchDB when you need JSON queries and secondary indexes. The test network shows both paths.

Frequently asked questions
No. Fabric has no native currency. You can implement tokens in chaincode if your use case needs them.
Fabric v2.5 is the current LTS stream with ongoing fixes. Fabric v3 introduces BFT ordering with SmartBFT and removes legacy components like the system channel, Solo, and Kafka. Plan upgrades accordingly.
Fabric uses a permissioned identity model and an execute‑order‑validate flow. Transactions are endorsed by required organisations, then ordered, validated, and committed for finality without forking.
Chaincode: Go, Node.js, Java. Client applications: use the Fabric Gateway SDKs for Go, Node, and Java.
