About the ComChain Alliance

The ComChain Alliance

The ComChain Alliance is an open network for Banks and Solution Providers within the Financial Communications and Compliance space. We are building an open standard for the provision, control and regulation of Financial Communications. The CCA is delivering a common schema to enable data records collated about common conversations to be linked together from disparate data sources. Blockchain technology is used to manage the configuration across the complex landscape whilst ensuring that the data collected is immutable

A Normalised Schema


The ComChain Alliance has released a draft of its normalised schema.  This has been designed in order to enable the disparate solutions providers to deliver integrated compliant voice infrastructure. The key focus areas are:

How to Configure such a solution enabling different services, users, resources to be easily managed across the infrastructure.

How data is then Captured by different systems and through leveraging the normalised data schema it can be linked together and seamlessly.

Finally how the data can be Accessed by internal risk and compliance teams, other solutions for analytics and indexing and even the potential for external regulatory bodies and clients. Noting that the data needs to be secured and proven to be immutable in accordance to the regulatory requirements.


A Distributed Ledger


The Distributed Ledger, built on BlockChain technology is the second key area of the ComChain Alliance approach. All data as it is created and shared is cryptographically hashed and the details are placed on the BlockChain ledger ensuring the immutability and therefore regulatory compliance.

Take a look at our ComChain Video.



Compliant & Secure

Realtime updates and sharing of all communication data. All data is anchored to a BlockChain ensuring the immutability of the data
Independently capturing meta data into a normalised data record. Enabling the integration between the communication flow and the lifecycle of a trade.

Schema Docs

The ComChain Alliance has released the first draft of its schema for normalised communication records. This Schema is based upon JSON-LD utilising common properties as defined by Schema.org where it makes sense.

The overarching goal of the Schema is to allow different parties to record and log the communication data in a normalised manner. In this way regulated organisations can seamlessly search through data sets where the data itself may be generated by multiple service providers.

For example, an organisation may have Fixed Line Voice Recording from one provider, Call Data Records from a second, Mobile Voice Recording from a third. Utilising the normalised specification ensures that attributes are common between each provider and additionally where two providers have parts of the same communication the detail can be seamlessly linked together.

The schema allows for the configuration of user resources and the definition of the parameters the different parties are required to capture. For example, a user handset regulated within a MiFID2 jurisdiction would require the fields as defined in the MiFID2 JSON-LD. This file will show the different required data with the service provider or system required to capture the data. That provider will create an equivalent file for each record (or transaction) with the actual content it has been requested to collect.

The Schema is built using the following components:
