Distributed ledger technology news portal BlockchainBriefing has launched ChainHQ, a database of blockchain investments documenting some $1bn (£600m) of Industry funding.

The subscriber-only portal provides intelligence on where investment is flowing and provides legal context to ledger technology, said a statement.

ChainHQ has tracked close to $1bn in funding received since 2009. Hardware firm 21 Inc, which produces bitcoin mining chips on a unique, individual mining basis, leads the industry with $121m received in funding since its inception in 2013, followed by Coinbase with $105m.

Funding has increased exponentially over the past few years, with the majority of the top 20 funded companies founded in 2011 onwards. However, only BitFury, Circle and Coinbase have completed Series C funding, with the majority of companies still in the early rounds of funding highlighting the opportunities ahead for further investment.

BlockchainBriefing's in-house team of analysts help players from across the industry make sense of the complex and rapidly evolving opportunities as they happen, and remain at the forefront of the industry.

The database can be searched via industry-specific keywords or company name, providing details on hundreds of blockchain technology companies, updated on a weekly basis.

David Morgan, founder and CEO of ComplianceOnline, said: "Through BlockchainBriefing we have witnessed the continued interest and activity within the blockchain industry. This new directory demonstrates our continued commitment to provide clients with the only news and information source they require to access critical and impartial business intelligence to keep abreast of blockchain developments."
