● 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. ● Bitcoin Core 0.21.0rc2 is a release candidate for the next major version of this full node implementation and its associated wallet and other software. It is also the safest wallet and currently involved more than 42 million wallet users. ● How will the migration tool from a Bitcoin Core legacy wallet to a descriptor wallet work? The removal of unneeded rules would simplify the construction of advanced Bitcoin scripts and the tools necessary to work with them. Before you invest any money, conduct your research and thoroughly review all of the basic rules and regulations of the trading platform you intend to use. 4917 disables the use of anchor outputs by default, a feature that was planned to be released in the upcoming 0.12.0-beta. Advanced users can still opt-in to using anchors. The legacy feeRate option in RPCs fundrawtransaction and walletcreatefundedpsbt still exists for setting a feerate in BTC/kvB; it is expected to be deprecated soon to avoid confusio

Discussion of the idea is still ongoing as of this writing. He kept writing about the digital currency in the pages of Bitcoin Magazine and other pubs. Although the source of the loss was not fully determined in the thread, it was suggested that virtual machine images or other curated collections of software, especially those designed for Bitcoin or other cryptocurrencies, provide an effective mechanism for delivering backdoored software to valuable servers. This week’s newsletter contains a warning about backdoored VM images. This week’s newsletter describes a proposal for using fidelity bonds on LN to prevent denial of service attacks, summarizes a PR to address a fee siphoning attack that could affect LN channels using anchor outputs, and links to a proposed specification for miniscript. This week’s newsletter links to a website that tracks miner support for taproot activation, announces a new organization funding Bitcoin research and development, and includes our regular sections with popular questions and answers from the Bitcoin Stack Exchange, announcements of releases and release candidates, and notable changes to popular Bitcoin infrastructure software. The more back links that a website has, the more popular the website is to the search en

Today, 10,000 bitcoins are worth more than $20 million (£15.4 million). Bitcoin ordinals, also known as Bitcoin NFTs, are a form of non-fungible tokens (NFTs) native to the Bitcoin blockchain. Blockchain technology has other uses too - it’s not all about cryptos. Bitcoin transactions are recorded and verified on a digital public ledger called blockchain. BTC/kB to sat/vB. Users are warned that the latter is a breaking API change, but it should be relatively benign. 742 improves the signer API by providing per-transaction information necessary for the signer to perform additional checks and provide a signature. ● HWI 1.2.1 is a maintenance release that provides compatibility with a recent version of Ledger’s firmware and improves compatibility with the BitBox02. Thus, the most important function of the BNB coin is to act as the fuel which powers the services the Binance exchange provides to its customers. As it appears Bitcoin news is like any other news, and provides investors with the best directions for making decisions during investments. Integration: moved here At the integration stage, the money re-enters the mainstream economy in legitimate-looking form - it appears to come from a legal transaction. This was the first time in history that you could see someone holding up a sign, in person or on TV or in a photo, and then send them money with two clicks on your smartphone: take the photo of the QR code on the sign, and click to send t

There are lots of things other than money which we consider valuable like gold and diamonds. ● Fidelity bonds for LN routing: Gleb Naumenko and Antoine Riard posted a to the Lightning-Dev mailing list to use stake certificates (another name for fidelity bonds) to prevent a type of channel jamming attack first described in 2015. These are attacks where a malicious user sends a payment to themselves or a confederate through a series of channels and then delays either accepting or rejecting the payment. Each routing node could then publicly announce its policy on how much value it would route given proof of a certain stake value. Since a route may cross more than a dozen channels, that means every bitcoin controlled by the attacker can prevent more than a dozen bitcoins belonging to honest nodes from being used for honest routing. 115, a recent update to the LN specification that has not yet been widely deployed makes it possible for an attacker to steal a portion of the bitcoins allocated to paying onchain fees for LN payments (HTLCs). The preferred solution to that problem is to simply not include any fees in HTLCs, eliminating the ability to steal fees and making the party who wants to claim the HTLC responsible for paying any necessary fees.
