15277 allows the Linux versions of Bitcoin Core to be deterministically compiled using GNU Guix (pronounced "geeks"). Altogether this should reduce the amount of trust users need to place in the developers of Bitcoin Core and the software used to build Bitcoin Core. Based on the examples collected, the report concludes with a summary of recommendations for developers. The examples of problems are not made to criticize the pioneering developers of those systems, but to help all Bitcoin developers learn how to master the powerful fee-management capability that RBF provides. 608 provides a privacy update to BOLT4 that makes it harder for a routing node to identify which node is ultimately receiving a payment. This week’s newsletter summarizes a proposal for an update to the LN gossip protocol. ● Gossip update proposal: Rusty Russell made a short proposal to update the gossip protocol that LN nodes use to announce what channels they have available for routing payments and what capabilities those channels currently support. Optional message extensions using Type-Length-Value (TLV) records allow omitting unnecessary details when the protocol defaults are being used (for more information about TLV, see the notable code and documentation changes section below).<

Also included are our regular sections withscriptiptions of new releases, release candidates, and notable code changes to popular Bitcoin infrastructure software. This requires much less setup than the currently-still-supported mechanism based on Gitian and so it is hoped that it will lead to a greater number of users being able to independently verify that the release binaries are derived solely from the Bitcoin Core source code and its dependencies. That said, www.binance.com the new open source explorer appears to be quite efficient compared to earlier open source alternatives such as BitPay Insight. One service said, "So Bitcoin address-related customer support tickets increased 50%, but the absolute number of tickets is so small that not sure we can give too much significance. We solicited input from a number of services including BitGo, BRD, Conio, Electrum, and Gemini regarding their customer support burden from use of bech32 addresses. Both Paxos, as the issuer, and the BUSD stablecoin, are regulated by the New York State Department of Financial Services (NYDFS), a leading regulator in this area. Bitcoins remind me of a story from the late chair of the Princeton University astronomy department. Can bitcoins become worthless? This computation can be done in a split second.<

If the first peer hadn’t sent the transaction within two minutes, your node would then request the transaction from the second peer who announced it, again waiting two minutes before requesting it from the next peer. ● How does one prove that they sent bitcoins to an unspendable wallet? If the first peer you request the transaction from has not sent it to you within a minute, you’ll request it from another randomly-selected peer. If you first heard about the transaction from a peer that connected to you (an inbound peer), you’ll wait two seconds before requesting the transaction to give an outbound peer a chance to tell you about it first. 14897 introduces a semi-random order biased towards outbound connections when requesting transactions, making it harder for attackers to abuse one of Bitcoin Core’s bandwidth-reduction measures. A network-wide attack could also make it easier to map the network and redirect transaction traffic in order to learn which IP address originated a transaction. Any subsequent trades coming from that order will be maker tr

Keys imported this way will be converted to the current wallet datastructure, but the eventual plan is for Bitcoin Core’s walletscripte descriptors internally. The term "blank" is used to distinguish a wallet without keys from an "empty" wallet whose keys don’t control any bitcoins. 15226 adds a blank parameter to the createwallet RPC that allows creating a wallet without an HD seed or any private keys. The wallet can then have private or public key material added to it (e.g. an HD seed using sethdseed or a watching-only address using importaddress). There have never been many tickets on this subject either before or after Bech32 so not sure this is an important point in making the argument for exchanges to make the switch. For the block queue to make sense, each block must contain a reference to the previous block (hashPrevBlock field). 784 updates BIP174 Partially Signed Bitcoin Transactions (PSBTs) to include a BIP32 extended pubkey (xpub) field in the global section.
