Our take
Bitcoin’s blockchain shows great potential to form the future foundation of financial infrastructure. However, working in advanced areas such as Bitcoin mining, asset issuance, and the Lightning Network goes beyond the fundamental framework, and requires expensive assistance from blockchain engineers. Blockstream develops technology to make it easier for businesses and individuals to make use of the Bitcoin blockchain, opening it up to a wider range of users.
Blockstream's offerings include tech to help people utilize advanced technology within the Bitcoin blockchain, including microtransactions on the Lightning Network, enterprise-class Bitcoin miner hosting, and layer-2 digital asset issuance. The company also provides Blockstream Satellite, a technology that leverages satellites to stream blockchain transactions without the internet, preventing them from being disrupted by connection loss.
Whilst the technology Blockstream is facilitating access to already exists, the company has smartly recognized the inaccessibility of its advanced features, and found its niche in providing an easier way to work with the technology. The company has seen impressive growth too, recently acquiring several companies and expanding its name across borders and it shows no signs of slowing down any time soon.
