This week’s newsletter includes a reminder to please help test the release candidate for Bitcoin Core’s next version, information about the development of Optech’s new public dashboard, summaries of two discussions on the Bitcoin-Dev mailing list, and notable commits from Bitcoin infrastructure projects. This week’s newsletter includes information about the first published release candidate for Bitcoin Core, news about BIP151 P2P protocol encryption and a potential future soft fork, top questions and answers from Bitcoin Stack Exchange, and some notable merges in popular Bitcoin infrastructure projects. This week’s newsletter includes action items related to the security release of Bitcoin Core 0.16.3 and Bitcoin Core 0.17RC4, the newly-proposed BIP322, and Optech’s upcoming Paris workshop; a link to the C-Lightning 0.6.1 release, more information about BIP322, and some details about the Bustapay proposal; plus brief descriptions of notable merges in popular Bitcoin infrastructure projects. The basic mechanism is that the authorized spender or spenders for an address generate scriptSigs and witness data (including their signatures) in much the same way they would if they were spending the funds-except instead of signing the spending transaction, they sign their arbitrary message instead (plus some predetermined extra data to ensure they can’t be tricked into signing an actual transaction).

The verifier’s software then validates this information the same way it would to determine whether a spending transaction was valid. Binance also offers a way to instantly purchase crypto, but the fees are 0.5 percent. If the changes are adopted, some of the notable advantages include: making it easier for hardware wallets to securely participate in CoinJoin-style transactions as well as other smart contracts, potentially easier fee bumping by any individual party in a multiparty transaction, and preventing counter parties and third parties to sophisticated smart contracts from bloating the size of multiparty transactions in a DoS attack that lowers a transaction’s fee priority. The Bitcoin consensus protocol doesn’t use ECDH, but it is used elsewhere with the same curve parameters as Bitcoin in schemes described in BIPs 47, m.blog.naver.com 75, and 151 (old draft); Lightning BOLTs 4 and 8; and variously elsewhere such as Bitmessage, ElementsProject side chains using confidential transactions and assets, and some Ethereum smart contracts. The existing draft cryptocurrency bill says so.

Binance is also one of a few cryptocurrency exchanges that have its desktop trading application for both macOS and Windows. As of June 2023, Binance Exchange is the largest cryptocurrency exchange in the world, with a volume of $8.3 billion. ICE’s 2017 revenues of $4.6 billion divide pretty evenly between those two main franchises. The estate include nearly 170,000 each of Bitcoins and its offshoot Bitcoin Cash, worth roughly $1.2 billion at today’s prices. In either case, it may be worth dedicating some engineering time towards tracking the proposals and proof of concept implementations to ensure your organization can easily adopt them if desirable. And secondly I actually want this site to be decent enough to be worth my huge "investment" of $9.95 a month. We want to build it in collaboration with the community. In addition to discussion about whether or not it’s good to have a large test chain for experimentation, it was also suggested that a future testnet might want to use signed blocks instead of proof of work to allow the chain to operate more predictably than the current testnet3, which is prone to wild hash rate oscillations. This would also allow the easy management of testnet disaster drills such as large chain reorganizations.

A discussion was started on the Bitcoin-Dev mailing list about resetting testnet again to provide a smaller chain for experimentation. Although proposed to the Bitcoin-Dev mailing list a few weeks ago, several aspects of the proposal were discussed this week. With this patch, your node will reject requests from an attacker to lock his funds and your funds for a period of more than 5,000 blocks (about 5 weeks). 2033: provides a new listforwards RPC that lists forwarded payments (payments made in payment channels passing through your node), including providing information about the amount of fees you earned from being part of the forwarding path. A private or permissioned blockchain, on the other hand, requires each node to be approved before joining. The vast number of valid private keys makes it unfeasible that brute force could be used to compromise a private key. All you need are two or more wallets that implement multiparty ECDSA key generation and signing.
