01History

The Liquid Network
On October 12, 2015, Blockstream announced the release of its Liquid sidechain prototype which could allow for the transfer of assets between the Liquid sidechain and the bitcoin main blockchain. On October 11, 2018, a production-ready implementation of the Liquid sidechain was officially launched, called the Liquid Network, which is designed to facilitate interoperability between the bitcoin main chain and the Liquid sidechain to extend bitcoin's capabilities.
Blockstream claims that Liquid reduces the delays and friction involved in a normal transfer of bitcoin. Blockstream asserts participating exchanges-including Bitfinex, BitMEX and OKCoin, can reduce counterparty risk for traders and enable near-instant financial transactions between their platform and other exchanges or a trader's wallet(s). New blocks are added to the Liquid sidechain every minute, as opposed to bitcoin's 10-minute block interval.
Blockstream Satellite
In 2017 Blockstream announced the availability of one-way satellite broadcasting of the full bitcoin blockchain. In 2018 Blockstream extended the bitcoin satellite network.
