Zenroom Stack

Multiplatform cryptography, microservices and blockchain interop | Zenroom-powered

Programmable by non-programmers

Programmable in the English-like DSL Zencode: based on Gherkin (BDD), Zencode is designed to be readable by non-programmer and written with minimal training. Zencode can be written in the online IDE Apiroom, which offers auto-complete, examples of each statement and extensive documentation.

Ultra portable

Based on the crypto virtual machine “Zenroom”: a super lightweight and ultra-portable component written in C, running on any architecture, on any OS, also running in the browser and in ultra low-power chips such as Cortex-M. Zenroom comes with binding for most programming languages and a single API, used to execute Zencode and returning the output as a buffer.


Microservices: the stack is designed to operate as an orchestra of microservices, with minimal dependencies and low footprint. Apiroom enables developers to create Dockerfiles and installers for microservices, entirely programmed in Zencode.

Nextgen cryptography

Zenroom can sign and verify using ECDSA, EDDSA, Schnorr on the most widely used elliptic curves such as SECP256K1, BLS381, ED25519 (and many more, see full list). Additionally, Zenroom is capable of zero knowledge proofs, multi-party computation, W3C-DID, W3C-VC and quantum-proof cryptography.


Blockchain interoperability is the ability of blockchains to communicate with other blockchains, enabling data exchange and transfers of tokens or assets across different distributed ledger technologies.

In Zenroom 3.0, Dyne,org implemented interoperability between Bitcoin, Ethereum, Fabric, Sawtooth, Iota, Planetmint, meaning that a single Zenroom smart contract can perform operations on each of these ledgers, allowing operations as NFT or token transfer along with multilayer and multi-source data notarization.

The capability has been exploited in’s blockchain oracle technology Zenswarm.
