You’ll need a Margin account to be granted access to funds from the Binance Exchange for use in leveraged trades. Primarily known for crypto-to-crypto trading-trading between two cryptocurrency pairs-the Binance exchange has some of the lowest cryptocurrency transaction fees. Interested readers can search for “paysafecard Bitcoin exchange” to try and locate relevant services. Also included are our regular sections describing changes to services and client software, new releases and release candidates, and notable changes to popular Bitcoin infrastructure software. This week’s newsletter summarizes a discussion about the minimum allowed transaction size and includes our regular sections with popular questions and answers from the Bitcoin Stack Exchange, releases and release candidates, and notable merges from Bitcoin infrastructure projects. This week’s newsletter relays a security announcement for LN implementations, describes a non-interactive coinjoin proposal, and notes a few changes in popular Bitcoin infrastructure projects. This week’s newsletter relays a request for comments on a proposed change to the BIP341 taproot transaction digest and briefly summarizes discussion about a new and more concise protocol for atomic swaps. For this change to have the maximum impact, other popular wallets need to implement support for creating compatible payjoin payments. 17595 adds support for reproducibly building the Windows versions of Bitcoin Core using GNU Guix.
● Breez wallet enables spontaneous payments: Version 0.9 of Breez wallet adds the ability to send spontaneous payments to Lightning nodes that support keysend. ● Bitcoin Core 0.20.0rc2 is the newest release candidate for the next major version of Bitcoin Core. ● Bitcoin Core 0.20.0rc2 is the most recent release candidate for the next major version of Bitcoin Core. Commenting on the protocol, Lloyd Fournier noted the “elegance” of a simplified version of the protocol that uses three transactions. ● Lightning Labs drafts Lightning Service Authentication Tokens (LSAT) specification: Lightning Labs has announced LSAT, a specification, which outlines a protocol for purchasing tokens (macaroons) over LN and using them in an application as both authentication and API payment mechanisms. If a significant number of people use payjoin, this makes the common input heuristic used by block chain analysts much less reliable, improving privacy for even Bitcoin users who aren’t using payjoin.
Advantages of the protocol are that it requires less block space than existing protocols, it saves on transaction fees (both by using less block space and potentially by requiring less urgency for its settlement transactions), it only requires consensus-enforced timelocks on one of the chains in a cross-chain swap, and it doesn’t depend on any new security assumptions or Bitcoin consensus changes. Binance is one of the largest and respected crypto trading platformthat allows traders to trade hundreds of cryptocurrency. So, are you curious about how to include OCO in your arsenal of the crypto trading risk management tool? ● Lightning Labs announces Faraday for channel management: Faraday is a tool for click web page LND node operators that analyzes existing channels and makes recommendations to close problematic or under-performing channels. These work by having the sender of a payment choose its payment preimage (normally chosen by the receiver), derive its payment hash (normally included in an invoice), encrypt the preimage to the receiver’s node pubkey, and send a payment with the encrypted data to the receiver secured by the payment hash.
In order to allow payment tracking, lightningd automatically creates an internal invoice for the decrypted preimage before claiming a spontaneous payment. The node will begin to drop transactions with the lowest feerate and increase its minMempoolFeeRate communicated to peers in order to keep the mempool size under that node’s maxmempool configuration. Each customer order uses a newly generated and independently tracked Bitcoin payment address. Pieter Wuille describes some of the downsides of using RFC6979 and why BIP340 uses a simpler nonce-generation algorithm inspired by Ed25519. ● Lightning-based messenger application Juggernaut launches: In a blog post announcing the first release of Juggernaut, John Cantrell describes how the messaging and wallet features are built using keysend payments. 18594 allows bitcoin-cli -getinfo to print the balance of each wallet loaded in multiwallet mode. The QR Stuff QR Code Scanner allows users to scan QR codes simply and easily from within your browser with no need to download and install a QR code scanning app or QR code reader software. An obvious use for spontaneous payments is donations, but a less obvious use is for sending chat messages with a payment such as via the LND-compatible WhatSat software and the C-Lightning-compatible noise plugin. By now, it should be apparent that when you “send” bitcoins to another person, you aren’t really sending anything directly to that person.
