● React native library photon-lib announced: Tankred Hase shared a new library, photon-lib for building Bitcoin wallet features using React Native. ● C-Lightning 0.9.2rc1 is a release candidate for the next maintenance version of C-Lightning. ● LND 0.10.1-beta.rc1 is the first release candidate for the next maintenance release of LND. ● What is the motivation for separating Bitcoin Core into independent node, wallet, and GUI processes? Michael Folkson outlines the benefits of Russell Yanofsky’s efforts to separate Bitcoin Core into different bitcoin-node, bitcoin-wallet, and bitcoin-gui processes. Modularity would allow users more flexibility in their setups and developers maintainability and security benefits. This new major version allows accepting large channels (by default, this is off) and contains numerous improvements to its backend features that may be of interest to advanced users (see the release notes). It contains new features, updated options, and bug fixes. This week’s newsletter contains a warning about backdoored VM images.

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. This week’s newsletter describes a proposal to make statechains deployable on Bitcoin without consensus changes, summarizes a discussion about a schnorr nonce generation function that helps protect against differential power analysis, and links to a proposed update to BIP322 generic signmessage. It is believed that this attack would be easier to execute when looking at the power consumption of a relatively complex hash function like SHA256 compared to a relatively trivial function like xor (binary addition). 87 to update the BIP340 specification for schnorr signatures with a recommended nonce generation function that claims to be more resistant against differential power analysis. For more information, Wuille links to a discussion between himself and several other Bitcoin cryptographers. This makes it an important topic of discussion in our Binance review. Discussion was still ongoing at the time of this writing.

Any remainder that still needs to be sent can still use other paths. When the receiver shares a direct channel with the spender, the spender knows exactly how much money is available to be sent in that channel. 1599 makes spending more intelligent when considering sending a multipath payment to a channel counterparty. ● Implementing statechains without schnorr or eltoo: statechains are a proposed offchain system for allowing a user (such as Alice) to delegate the ability to spend a UTXO to another user (Bob), who can then further delegate the spending authority to a third user (Carol), etc. The offchain delegation operations are all performed with the cooperation of a trusted third party who can only steal funds if they collude with a delegated signer (such as previous delegates Alice or Bob). ● Backdoored VM images: a user on Reddit posted about losing funds after using an AWS image that came with a Bitcoin full node already installed and synced to a recent block. Because anyone who was ever a delegate can trigger an onchain spend, statechains are designed to use the eltoo mechanism to ensure an onchain spend by visit the following webpage most recent delegate (Carol) can take precedence over spends by previous delegates (Alice and Bob), assuming the trusted third party hasn’t colluded with a previous delegate to cheat.

● Sparrow Wallet adds payment batching and payjoin: Sparrow’s recent 0.9.6 and 0.9.7 releases added payment batching and payjoin capabilities respectively. ● What’s the most efficient way to create a raw transaction with a specific fee rate? ● Will there be a testnet4? There are countless articles on the subject, ranging from how blockchain will transform the entertainment industry to how blockchain can reassure you that the fish you are about to enjoy for dinner is from a sustainable source. There are a number of similar services that range from creating elaborate paper wallets to creating simple ones. The exact number of bitcoin millionaires is uncertain as a single person can have more than one bitcoin wallet. 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. This payment source was invented for online purchase and sale of products and services. 3. How do put them for sale?
