Technical components

Multi-level assets security mechanisms

Every kind of crypto assets deposited at COBINHOOD will be stored in an offline multi-signature (multisig) wallet. It is estimated that 98% of assets will be stored offline, while 2% of assets will remain in an online wallet allowing for faster user deposit and withdrawa. Each offline multisig wallet consists of 8 HSMs (Hardware Security Modules), which will require passcodes from 5 out of the 8 HSMs to be accessed. If one of the HSM administrators is compromised, the multisig wallet will remain secure. Furthermore, the administrators of the HSMs are located in different countries (geo distributed) adding to security system. Furthermore, all crypto asset deposits in online wallet will be backed by insurance.

Self-trading restriction

Self or bot trading will also be regulated in the COBINHOOD Exchange as the trading engine is equipped with multiple automated configurations to prevent self-trading of orders entered by the same person with multiple accounts. Furthermore, machine learning and data analysis will also be set up to bolster security mechanisms for self-trading restrictions.

Distributed Order-Matching Engine

The COBINHOOD platform is built on Google Cloud Platform and is programmed with Golang for high concurrency. By design, each trading pair is transmitted through a dedicated order matching engine to ensure high order matching speed. COBINHOOD’s order matching engine is composed of microservices, including frontend, API backend, order matching system, and job/message queue services deployed with Docker and Kubernetes to achieve high availability and high scalability. All of the transaction records are stored in Spanner DB, a Google Cloud Platform database that features strong consistency and the ability to do horizontal auto-scaling. The information of the order book is stored in Redis cluster, an in-memory database technology featuring horizontal auto-scaling and distributed in-memory replication.

Transactions and order book updates are sent through Web Application Messaging Protocol (WAMP) to achieve real-time information update at every tick. In stress tests, COBINHOOD is able to process 1,154,284 orders per second and achieve 10,142 order book updates per second for each trading pair on average—making it the world’s first cryptocurrency exchange capable of high-frequency trading. At COBINHOOD, software development follows test-driven development (TDD). By using Docker and Kubernetes together with CircleCI, continuous delivery (CD) and continuous integration (CI) we can ensure system stability and strength.

KYC and AML compliance

COBINHOOD has developed a propriety smart-KYC process which involves multi-layer user-risk identification, transaction monitoring, and various other steps which will allow us to create necessary measures in classifying or taking the right actions for an account. It is also seen to gradually improve as AI and machine learning mechanisms mature into a smarter, highly-responsive KYC tools.

Moreover, all the employees undergo periodic AML and CTF training to ensure that the team is well versed in these issues, as well as establishing an AML committee to improve our service. Third-party service providers also help audit and keep our process in check with the latest security standards.
