How to Set up and Secure your Bitcoin with the Foundation Passport Wallet
Messing about with new script types and custom locktimes can be dangerous if you don’t know what you’re doing, so please take care. ● Reducing transaction analysis opportunity because transactions that opt in to RBF look different onchain than transactions which don’t. ● Possible amount of signatures with MuSig? › It is possible for someone to steal your Bitcoin Wallet (private Key), but you can mitigate the risks if you do things to protect yourself. If someone is asking you to provide them with a "Testnet" address, then only provide it if you are to get the BTC for free. If someone requests payment to an address for P2TR before you think it’s safe, that’s their risk to take. ● Sparrow 1.4.3 supports P2TR: Sparrow’s 1.4.3 release supports single-sig P2TR wallets on signet and regtest. ● More convenient for hardware signing devices: since the rediscovery of the fee overpayment attack, several hardware signing devices have refused to sign a transaction unless each UTXO spent in that transaction is accompanied by metadata containing a copy of significant parts of the entire transaction which created that UTXO.

10823 as an alternative approach-it allows any transaction to be replaced, but only after the transaction had spent a certain amount of time in a node mempool (originally proposed as 6 hours; later suggested to be 72 hours). ● Suredbits announces DLC wallet alpha release: Suredbits’ bitcoin-s software includes a GUI and allows the execution of Discreet Log Contracts (DLCs) on the Bitcoin blockchain using an oracle. Nahum also noted that this feature does not hinder blockchain analysis any more than blocking IP address data that hits the Blockstream servers does. Because of the address reuse, its easy to see on the blockchain that some bitcoins are being sent to an exchange. Every business's expenditures and payroll are now necessarily public information. Using P2TR for single-sig now also allows your wallet to upgrade to multisignatures, tapscripts, LN support, or other features later on without affecting the privacy of your existing users. ● Privacy: although some privacy is lost when early adopters change to a new script format, users switching to taproot also immediately receive a privacy boost. Every wallet is different, with varying levels of security and privacy. ● Help full nodes: the overall security of the Bitcoin system depends on a significant percentage of Bitcoin users verifying every confirmed transaction with their own nodes.

● Specter v1.4.0 released: Specter v.1.4.0 adds a feature to “cancel” a transaction using BIP125 opt-in Replace-by-Fee (RBF). ● Trezor Suite adds RBF support: Trezor’s wallet software, Trezor Suite, added support for Replace-by-Fee (RBF) in version 21.2.2. RBF is on by default and also supported by some of Trezor’s hardware devices. Using bitcoind If you have Version 7 or later it is now trival. It won’t matter whether a UTXO was received to an old version or a new version of your software-both UTXOs will look the same onchain. If a transaction includes any bech32m addresses after taproot activation, the descriptor wallet will also use a P2TR change output. Typically, a Bitcoin transaction takes anywhere from 10 minutes to several hours to clear. Over five years later, it appears very few merchants today are accepting unconfirmed transactions as final, and it’s not clear how many of those that do are actually checking for the BIP125 opt-in signal and treating those transactions differently. Maybe some wrong setting in your ledger live, so you are not seeing the balance.

Or is it safe enough to give each account an address and record a balance and transaction history tied to each account? This opt-in behavior was proposed as a compromise between people who wanted to allow transaction replacement, such as for fee bumping or additive payment batching, and people who objected because allowing replacement simplifies building tools that defraud merchants who accept unconfirmed transactions as final. Has developer’s fee for this tool is 0.65%. Moreover, this mining tool is perfect for users who use Windows 10 operating system. Retaining a few connections to peers on anonymity networks is highly desirable both because it allows transaction creators to use those networks to hide their network identity and because the ability to receive blocks over those networks in addition to the regular Internet Protocol can prevent some types of eclipse attacks. If every transaction could be replaced, this wouldn’t be a concern.
