Projects

  • 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
  • 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.
  • Blockstream has released source code for the smart contracts on blockchain language Simplicity; Simplicity has been built to be compatible with Blockstream’s Elements platform, Elements is an open source, sidechain-capable blockchain platform
  • Is open sourcing its Proof-of-Reserve tool for increased transparency; most proof-of-reserve operations require substantial transactions that put exchanges at high security risks; Blockstream's innovative tool uses common sense and UTXO values to prove the extent of reserves; however, revealing UTXO values themselves is not a safe method, a problem Blockstream is currently working to rectify
  • From the Bitcoin Optech Newsletter #69 (23-10-2019):

"Blockstream Green Tor support: Version 3.2.4 of the Blockstream Green Wallet adds built-in Tor support for both iOS and Android. While Tor was supported in previous Android versions, it required a separate application whereas both Android and iOS versions are now bundled with Tor support."

"In 2019, Blockstream launched Blockstream Pool and announced it had been previously mining for a select few high-profile clients like Fidelity. Blockstream said it bought $25 million worth of mining machines from MicroBT. The machines are to be deployed through Blockstream's facilities in Canada and the U.S."
