Chainalysis is a blockchain data platform founded in 2014 that supplies data, software, services and research to government agencies, cryptocurrency businesses and financial institutions. Its tools support three main functions: investigation, compliance and market intelligence. Organisations in more than 70 countries use the platform, as do nine of the top ten cryptocurrency exchanges. The company says its technology has helped recover more than $34 billion in illicit funds.
The best-known product is Reactor, described as the world's first crypto investigation tool, built to investigate and disrupt cryptocurrency crime. Around this sits a wider stack of blockchain analytics and blockchain intelligence capabilities spanning data science, cryptocurrency investigation, compliance technology, risk assessment, market intelligence and financial data analysis. The work sits at the intersection of large-scale data engineering and applied analysis of public blockchains.
The team combines expertise in law enforcement, national security, regulation, tax, compliance and data science, and works on high-profile criminal cases alongside routine compliance and risk workflows. Chainalysis describes its mission as building trust in blockchains so that cryptocurrency can realise its potential to make the global economy bigger, fairer and more deeply integrated. Its customers span government and public sector, law enforcement, financial services, national security, regulation and compliance, and tax.
