Company
The company is focused on developing bitcoin applications specifically sidechains, as well as other applications. Blockstream has raised $76M to date from investors including Horizons Ventures and Mosaic Ventures. Blockstream employs several prominent bitcoin developers, including Adam Back (President, Blockstream), Gregory Maxwell (CTO, Blockstream), Mark Friedenbach (Co-founder, Blockstream), Pieter Wuille (Bitcoin Core developer), and Christopher Allen (co-author of IETF Transport Layer Security. Blockstream is one of the largest contributors of funding for Bitcoin Core.
Liquid sidechain
On October 12, 2015, Blockstream announced the release of its Liquid sidechain which could allow for the transfer of assets between the sidechain and the main blockchain. Blockstream produces software that facilitates interoperability between the main chain and the sidechain. Blockstream claims that Liquid reduces the delays and friction involved in a normal transfer of bitcoin. Blockstream asserts participating exchanges–Bitfinex, BTCC, Kraken, Unocoin and Xapo can make near instant exchanges between their accounts and orderbooks. The company has proposed that the Liquid sidechain, which is a pegged sidechain, be added to the bitcoin protocol. The source code for sidechains has been released on an open source basis.
Initiatives
In addition to its corporate initiatives, blockstream is also involved in a number of community steering and open source programs.
Bitcoin Core
Blockstream is one of the largest contributors of funding for Bitcoin Core.
Lightning Network
Blockstream hired Rusty Russell, a well-known developer famous for his work on Linux kernel, to develop an implementation of the Bitcoin Lightning Network (LN). Russell has a four-part LN explanation on his blog. The Lightning network proposes to reduce transaction costs by allowing nodes to hold some transaction data in the cache before submitting it to the chain.
In May 2016, Blockchain.info announced Thunder, which claims to be an implementation of Lightning.
Elements Project
Blockstream released an open source codebase and testing environment for its sidechains product to public under open source license. The Elements Project is a community effort to create and test new extensions to the Bitcoin protocol, whose early contributions include Confidential Transactions by Gregory Maxwell, and Segregated Witness by Pieter Wuille.
Hyperledger
Blockstream participates in Hyperledger as a general member. The Hyperledger project is a cross-industry collaborative effort to create blockchain based open standard for distributed ledgers for globally conducted business transactions.
Controversy
Bitcoin developer Mike Hearn quit the Bitcoin project over a dispute involving a failed block size increase, which Hearn claimed was being opposed by Maxwell of Blockstream.
However, Wladimir van der Laan, the Chief Maintainer of Bitcoin Core, is funded by MIT's Digital Currency Initiative and only merges pull requests to Bitcoin Core that have widespread technical consensus.
