Trading Forex or equity or now Bitcoin is not just about skill but also about how aware the traders are. To ensure that the latest state is recorded onchain, a channel should be unilaterally closed when there are only this many blocks until an LN payment has to be settled. Compared to previous designs for payment pools (such as joinpool), the CoinPool design focuses on allowing participants to make offchain commitments to transactions between the members of the pool. In that sense, the protocol acts as a sort of generalized channel factory that applies not just to LN but to many protocols that create onchain transactions with unique fingerprints. This week’s newsletter describes the new libminisketch library for bandwidth efficient set reconciliation, links to an email about Schnorr/Taproot plans, and mentions an upcoming LN protocol specification meeting. This week’s newsletter links to a discussion about routed coinswaps and includes our regular sections with summaries of questions and answers from the Bitcoin Stack Exchange, releases and release candidates, and notable changes to popular Bitcoin infrastructure software.
Also included are our regular sections with notable changes to services, client software, and infrastructure software. Notable changes this week in Bitcoin Core, C-Lightning, Eclair, LND, Rust-Lightning, libsecp256k1, Hardware Wallet Interface (HWI), Bitcoin Improvement Proposals (BIPs), and Lightning BOLTs. We have heard from wallet providers that a reason for their hesitation to default to receiving to bech32 addresses is concern that they’d see a significant increase in customer support requests. 0 (the default value): fee calculations are made using both coin selection algorithms. 1: partial spend avoidance is completely disabled to optimize for faster fee calculations, which may be useful for very large wallets with many UTXOs. 19743 add a new maxapsfee (“max avoid partial spends fee”) configuration option to specify the maximum amount of extra fee you’re willing to pay to avoid partial spends when the existing avoidpartialspends configuration option is disabled. With this change, it becomes possible to fee bump commitment transactions that may have been signed days or weeks earlier, when the current feerates would’ve been hard to predict. The standardization of these preimage fields was found to be necessary for miniscript-aware finalizers, though they can be used by any PSBT finalizer needing to satisfy hash preimage challenges (e.g. for onchain LN commitment transactions).
955 updates BIP174 to standardize supplying hash preimages in PSBT input records. 3954 updates both the fundpsbt and utxopsbt RPCs so that they can each take a locktime parameter that specifies the nLockTime of the transaction to create. 785 updates the minimum CLTV expiry delta to 18 blocks. This has led some LN implementations to use route-finding algorithms that optimize for routes with low CLTV expiry deltas, which has in turn led some users to set their deltas to values that are especially unsafe. However, 바이낸스 회원가입 the higher the expiry is, the more time a payment could become temporarily stuck in an open channel (either by accident or deliberately). Payment secrets are supported by all LN implementations and will eventually be made compulsory by C-Lightning; logging which payments are using payment secrets makes it easier for the developers to know when it’s reasonable to make that change. Various degrees of support for anchor outputs have already been merged into several LN implementations.
Anchor outputs also provide greater security because, if feerates do increase beyond what was predicted, the node can fee bump its commitment transaction. This extends commitment transactions with two extra outputs-one for each counterparty-which can be used for Child Pays For Parent (CPFP) fee bumping. ● What’s the most efficient way to create a raw transaction with a specific fee rate? Stack Exchange user Darius asks about the interplay between UTXO selection and feerate when constructing a transaction. Constructing structures that can be sold for money. Federally regulated U.S. banks can now officially custody crypto assets. Excluding grantor trusts – limited to accredited investors – such as the Grayscale Bitcoin Trust, the current crypto ETF market totals about $2 billion, according to MorningStar Direct, less than 2% of overall crypto market. The more legitimate businesses that use Bitcoin, not only will the overall Bitcoin economy grow in general, but the more difficult it will become for governments to cramp down on the exchanges as it will have a legitimate use. We may anticipate more major companies investing in the metaverse as blockchain gaming becomes popularity.
