Dual funding and splicing mechanisms allow initial negotiations between node to
allow the node on the other end an opportunity to put funds at channel opening
time or after it. Finding liquidity is a problem that had solutions suggested
all the way back in November, the suggestion was, in summary, that a node will
advertise initial liquidity matching via their
node_announcement, this is meant
to help these nodes source inbound capacity from a market of advertised
liquidity rates as set by other nodes.
After a recent spec meeting, developer Rene Pickhardt noticed a potential privacy issue with this schema: a node can spam another probing for a lower bound for the amount of BTC available by this node, each time aborting the channel establishing before locking any of its own Bitcoin.
Blockstream has just introduced Liquid Core, a multiplatform desktop wallet for transacting Liquid Bitcoin.
Users can deposit to supporting exchanges and withdraw as well as engage in peer-to-peer transactions. In addition, transactions are significantly faster (settled in two minutes) and users enjoy a default confidential transaction setting that hides sensitive transaction details such as transaction asset and amount from third parties.
Anyone familiar with wallets can use the Liquid Core wallet although Bitcoin Core users will find it much easier to navigate. Requirements and instructions on how to use the wallet are available on the website. See more details to get started.
