● Help test Bitcoin Core 0.17.1RC1: the first release candidate for this maintenance release has been uploaded. The new desc fields are not expected to be particularly useful at the moment as they can currently only be used with the scantxoutset RPC, but they will provide a compact way of providing all the information necessary for making addresses solvable to future and upgraded RPCs for Bitcoin Core such as those used for interactions between offline/online (cold/hot) wallets, multisig wallets, coinjoin implementations, and other cases. Support tickets are submitted via an online form featured on the website, and responses are made via email. ● Releases: LND 0.5.1 is released as a new minor version with improvements particularly focused on its support for Neutrino, a lightweight wallet (SPV) mode that LND can work with to make LN payments without having to directly use a full node. And, if you are a pro or expert trader, you can even offer your services via social trading platforms and earn profits whenever any trader copies your trade to make a profit. And, because of its high volatility and strong market trends, more and more traders are getting involved in it.
This protocol requirement means that a spending transaction with a high feerate can, through averaging, make it profitable to mine its unconfirmed parent transaction even if that parent has a low feerate. Although this provides trustless security, it has an unwanted side-effect related to transaction fees-the parties may be signing channel states weeks or months before the channel is actually closed, which means they have to guess what the transaction fees will be far in advance. This release also fixes an accounting bug for users of the btcwallet backend where not all change payments to yourself may have been reflected in your displayed balance. Anyone intending to take this version is encouraged to review the list of backported fixes and help with testing when a release candidate is made available. The new method allows specifying what data to consider and returns a list of nodes scored by the algorithm (higher scores being better). Alternative recommendation engines can return their own scored recommendations, and the user (or their software) can decide how to aggregate or otherwise use the scores to actually decide which nodes should receive channel open attempts.
If at all possible, it is preferable to build software and services in a way that doesn’t require the types of fast and arbitrary searches that block explorers make convenient. However, to make this safe for LN no matter how high fees get, nodes need to also support relaying packages of transactions that include both low-feerate ancestors plus high-feerate descendants in a way that doesn’t cause nodes to automatically reject the earlier transactions as being too cheap and so not see the subsequent fee bumps. But for users of multiparty protocols, a malicious counterparty can exploit the limits to prevent an honest user from being able to fee bump a transaction. That addition can be in a previous block or it can be earlier in the same block as the spending transaction. An address is solvable when a program knows enough about its scriptPubKey, optional redeemScript, and optional witnessScript in order click here for info the program to generate an unsigned input spending funds sent to that address. ● CPFP carve-out: in order to spend bitcoins, the transaction where you received those bitcoins must be added to the block chain somewhere before your spending transaction.
There’s no minimum deposit limit on Binance as long as the amount covers the transaction fee. In the case of Nonsufficient Funds, Non-BNB fee structure is used. UNSAFE, and briefly describes a proposal to simplify fee bumping for LN commitment transactions. This week’s newsletter describes a proposal to tweak Bitcoin Core’s relay policy for related transactions to help simplify onchain fees for LN payments, mentions upcoming meetings about the LN protocol, and briefly describes a new LND release and work towards a Bitcoin Core maintenance release. Whereas the carve-out policy is probably easy to implement, package relay is something that’s been discussed for a long time without yet being formally specificed or implemented. Although block explorers have been a mainstay of Bitcoin web applications since 2010, we do note that the method used by block explorers of maintaining multiple indexes over all block chain data inherently has a poor scalability characteristic-their cost increases over time as the block chain grows-and so it is generally inadvisable to build software or services that depend upon your own block explorer. UNSAFE. A signature hash is the data committed to by a signature in a transaction. 2081 adds RPCs that allow signing a transaction template where some inputs are controlled by LND.
