    <br> The 30-minute presentation covers each point concisely, making it an excellent high-level overview for anyone interested in learning about the Bitcoin fee market and how to mitigate expected fee increases. We don’t usually cover refactors, but this one has a tantalizing comment: “this is in preparation for re-using these validation components for a new version of AcceptToMemoryPool() that can operate on multiple transactions (‘package relay’).” Package relay could allow nodes to accept a transaction below the node’s minimum feerate if the transaction came bundled with a child transaction whose fee was high enough to pay the minimum feerate for both it and its parent. For scripts that need signatures or other data from multiple wallets, miniscript can guide the wallet into creating all the witness data it can so that the data can be bundled into a Partially Signed Bitcoin Transaction (PSBT). The miniscript compiler can convert the policy into an efficient P2WSH script and check that it doesn’t violate any of Bitcoin’s consensus rules or Bitcoin Core’s transaction relay and mining policy. This week’s newsletter notes a change to Bitcoin Core’s consensus logic and Highly recommended Resource site announces a new feature on the Optech website for tracking technology adoption between different wallets and <br>i<br>.
    The News section from this week’s newsletter introduced a new feature on the Optech website. This week’s newsletter announces the newest release of C-Lightning, briefly describes several proposals related to LN, and provides our usual sections about bech32 sending support and notable changes to popular Bitcoin infrastructure projects. Significant changes to the bitcoin price are notable in the context of bech32 because transaction fees are paid in bitcoin terms rather than dollar terms. 16400 refactors part of the mempool transaction acceptance code. 2924 abstracts C-Lightning’s database handling code and SQL queries so that it can be adapted to handle other backends besides the default sqlite3. Our QR Code Generator is FREE for anyone to use with no sign-up or account required – fully functional, 100% ad-free, permanent QR codes that don’t expire. However, many of these wallets also use P2SH-wrapped segwit addresses for receiving change sent from themselves to themselves. However, spending transactions contain more than just scriptSigs and witness data, so the way we usually compare savings is by looking at prototype transactions. However, interested readers investigating alternative, Linux-compatible options should note that many of these are not officially packaged by various distributions. 16248 extends the whitelisting configuration options in Bitcoin Core to allow specifying which services should be provided to different IP addresse<br> <br>ges.
    The action opens a dialog that lets the user name the wallet and set various wallet options. Over time, the exchange has proven itself reliable and responsible to its customers and has lived up to set standards and regulations, cementing its reputation in legitimizing cryptocurrencies as an asset class. So we’ve been talking about Bitcoin but there are lots of different cryptocurrencies and people are creating ones all the time, some for good technical reasons or at least plausible, others as potential cash grabs and so on. In my country there are no clubs or computer museums that would connect such people with similar interests, which is a pity, because I couldn’t get anyone to assist me. Policies are composable, allowing any valid sub-expression to be replaced by another valid sub-expression (within certain limits imposed by the Bitcoin system). 656 adds a feature bits specification to BOLT11, allowing payments to indicate which features they suppor<br> <br>uire.
    Day to Day, a well-known United Arab Emirates bargain retailer, was the first to accept Bitcoin payments. The 2019 Executive Briefing was our first event targetted at executives and management, and presented important technical topics at a high-level for decision makers at Bitcoin businesses. Technical analysts work with a different approach. This PR has been tagged for backport to 0.17.1 whenever work on that should start. For any of these options, any third-party looking at the block chain data sees only a single signature and no direct information about how many parties are involved, but each of the three key holders knows which two of the participants’ public keys were used to create the particular aggregated key that the spending signature matched, giving them private auditability. The RPC already added a checksum to any descriptor provided without one, but it also normalized the descriptor by removing private keys and making other changes users might not want. For example, by making state changes in eltoo similar to state changes in Bitcoin, this would allow tools and contract protocols built for regular Bitcoin transactions (state changes) to be easily reused within p<br>nt channels.
