What we do

CommerceBlock‘s public blockchain based infrastructure enables the distribution, exchange and storage of assets through the execution of smart contracts. CommerceBlock has extended the federated sidechain protocol with easy-to-use libraries for issuing assets, constructing complex trade flows, enforcing multiparty escrow and producing trusted regulatory audit trails.

How it works

Fault Tolerance and Privacy

There is no room in competitive business environments for the exposure of sensitive private data. When utilizing the protocols built by CommerceBlock, all contract details are hidden in zero knowledge and distributed across our federated sidechain infrastructure. Strong cryptography and regular attestation to public blockchains provide privacy preserving and fault tolerant product offerings to our clients.


Cryptographic primitives require years of carefully honed expertise to safely implement and test; it is for this reason that CommerceBlock relies upon open source and peer reviewed cryptographic primitives. Our libraries leverage homomorphisms, zero-knowledge protocols and other advanced techniques to enable the client side management of trade details and customer funds.


Dependencies on trusted intermediaries create inefficiencies and high transaction costs for participants in capital markets. CommerceBlock removes the need for these intermediaries by providing direct access to protocols that allow engineers unfamiliar with the intricacies of smart contracting to safely bridge the gap between public blockchains and federated sidechains.

Our History

Founded by Nicholas Gregory in 2016, CommerceBlock has a long history in the Bitcoin ecosystem. After watching the protocol and its surrounding community develop over the last few years, the founding team became inspired by the idea that they could extend its usefulness to enterprises across the globe. Their first step was to specify and implement BIP 175, a protocol that allows businesses to leverage cryptography in new and exciting ways. Looking forward, they are excited to contribute back to the federated sidechain protocol, Elements.
