It looks like https://bitcoincore.org/ is the one run by the people who run the Github bitcoin/bitcoin project (the actual core developers) since it is the one listed on their Github page: https://github.com/bitcoin/bitcoin If you want the absolute best source for the client directly from Bitcoin Core devs then I would use that site or their Github page for ...

TL;DR: Wallets SHOULD allow sending to all bech32m addresses at this point, but wallets MUST NOT request P2TR outputs before the Taproot spending rules are enforced on the network¹. The design of segwit anticipated the lengthy process that is the adoption of optional features. Case in point, segwit activated in August 2017, yet Blockchain.com, a wallet ...

This functionality in the Bitcoin Core wallet has deliberately not been merged pre activation to prevent users from easily generating and giving out Taproot addresses prior to the Taproot rules being enforced. You can get around this by importing a Taproot descriptor into the wallet prior to this PR being merged as described here, here, here or here but that ...

No your funds would still be at risk. There are only a few popular wallets that use seed phrases. Most wallets use BIP39(https://en.bitcoin.it/wiki/Seed_phrase) but there are some that use different versions or no seed words at all. Electrum does not ouse BIP39, see their docs explaining why. https://electrum.readthedocs.io/en/latest/seedphrase.html It would ...

I'm the CEO at Muun wallet. Muun does rely on backups since the Emergency Kit is a backup, just not using mnemonics. The problem with mnemonics is that they don't contain a lot of stuff needed for the recovery of a multisig / lightning wallet, like the derivation paths, scripts, etc. When using Muun, you will back up two pieces of data: the Recovery Code and ...

Part of the design is that compromise of their service is a little bit pointless. They can not sign transactions spending your money to begin with, as the transactions also need a signature from your wallet too. There’s no scenario in which the service can spend your money without your participation to some degree. In unlikely scenario the service attempts ...

Such a transaction is standard and would relay. However neither the Bitcoin Core wallet (via the bumpfee command) nor the Electrum wallet (via the GUI) would create such transaction. More information about fee bumping in the Bitcoin Core wallet can be found here.

A HD wallet doesn’t know what indexes of a seed to scan for until the ones prior have been used, which can’t be discovered out of order. To allow for out of order scanning the address gap limit would need to be prohibitively large, and might still result in re-scanning filters if the wallet is particularly active.

https://bitcoin.org/en/bitcoin-core/ says For the latest developments related to Bitcoin Core, be sure to visit the project’s official website. (which is a link to https://bitcoincore.org/) So there has been a deliberate separation between the Bitcoin.org project and the Bitcoin core project. This would make sense as Bitcoin.org provide information and ...

Does it create a public key based of private? Yes, a cryptographic routine exists that computes the public key from the private key. maybe on the wallet.dat file? All modern wallet software generates keys derministically from some sort of master key, or seed phrase. That master key is stored in the wallet, and all other private keys are derived from it, ...

No, it's not known, and information like that generally won't be publicly released. Bitcoin addresses aren't generally publicly associated with the real-life identities of their owners. I would expect a company like Tesla to have the bulk of their cryptocurrency assets stored in institutional custody regardless, for liability and regulatory reasons.

Computers are not connected to the blockchain. Computers running Bitcoin software connect to a few other computers that are running Bitcoin software. Each of these computers keeps its own copy of the blockchain if they are what is known as a full-node. For example any computer running the "Bitcoin core" wallet software is a full node. So even if ...

I already have bitcoind running with a 4GB pruned database, and I'm hoping that will be enough. It is! By running bitcoin-core, you can pull this data in an easy, trustless way. I would recommend creating and displaying a new address to your patrons each time a new donation is received (so as to avoid address reuse, which is detrimental to your privacy, and ...

Different networks use different address prefixes. In Bitcoin mainnet: P2PKH addresses: 1... P2SH addresses 3... P2WSH and P2WPKH addresses: bc1q... P2TR addresses: bc1p... (see BIP 341) In Bitcoin testnet and signet (see BIP 325): P2PKH addresses: m... or n... P2SH addresses: 2... P2WSH and P2WPKH addresses: tb1q... P2TR addresses: tb1p... Bitcoin Core'...

I have beginner skills as Full stack Developer and am looking to help developing a crypto wallet with a small start up. Building a wallet from scratch is a major endeavor and fraught with security responsibilities. I'd recommend that you instead use an existing wallet or service. You will probably find that getting a small startup off the ground will keep ...

The mitigation is the absolutely massive address space. Other than that, there is no way to 'protect' or otherwise 'claim' a keypair/address as yours and yours alone. If someone (by some unfathomable coincidence) manages to generate the same address that your wallet did, then you will both be able to spend any funds locked to that address. Thankfully, the ...

Can you close the wallet and switch [off] the moment you've clicked 'send' Yes. Once the transaction is broadcast, the wallet has no further role in the processing of the transaction. The exception would be, for example, if you use RBF and decide to instruct the wallet to up the fee. But this is a rare exception and isn't something a typical wallet would do ...

Can you really trust a non-open-source desktop wallet? No Shouldn't everyone be using exclusively open-sourced wallets for this reason? Yes, everyone should use open source wallets. And still use small amounts in hot wallets or wallets that are relatively new and experimenting with new features. More details: What stops a wallet from stealing bitcoins?

You can import a descriptor composed of the xpriv(s) (or xpub(s) if you just want to watch the coins) to the bitcoind wallet, and then rescan the block chain for transactions involving derived key up to a configured gap limit. For importing the descriptor, use the importmulti RPC call in versions <0.21 and the importdescriptors RPC as of 0.21 (upcoming). ...

Does that mean when you buy bitcoins on Robinhood, Coinbase, Coinbase Pro, Gemini, or even the trust GBTC, they are all Web Wallets? You can call them exchanges or web wallets but in both cases you don't hold the private keys and just looking at numbers based on the database used by website/app until you withdraw bitcoin to an address for which you own the ...

Yes it is possible, as long a Binance is willing to let you withdraw your coins. Steps: Open your electrum wallet. Open the 'Receive' tab, and copy the 'receiving address' to your clipboard. Open Binance. Navigate to the page where you can initiate a withdrawal. Paste the 'receiving address' from Electrum into Binance withdrawal form. Be sure to triple ...

Spending Bitcoins requires the knowledge of the private key corresponding to the address holding the funds. These keys are managed by each user individually. Without the key, the coins are rendered unspendable. Given the lack of details, I assume that you no longer hold a copy of the wallet that held the private keys. If that is the case, your funds are lost....

"Buy the dip" is used by traders even for legacy markets and nothing specific for Bitcoin. This will undoubtedly incur high network fees For paying less in fees while moving bitcoin from/to exchange do the following: Use P2P exchanges: Bisq and HodlHodl Use open source bitcoin wallets with active development and support for segwit Use RBF for ...

You can verify the legitimacy of Coinkite's Coldcard key generation, assuming that you've used Coldcard's feature of generating the entropy for the seed words by throwing dice (the key generated will be based on your dice throws and so wasn't surreptitiously built into the card). The web page https://coldcardwallet.com/docs/verifying-dice-roll-math gives ...

Disable Private Keys the wallet is set in watch-only mode, only public keys can be imported into wallet. You can use it, for example, to track transactions or generate PSBT transactions to be signed elsewhere. (if this option is enabled you don't need Encrypt Wallet, because only private keys are encrypted) Make Blank Wallet the wallet starts out with ...

To accomplish this you will not 'transfer the bitcoin', you will just import the keys that can spend your bitcoin, into a new wallet. Not all wallet software will support importing/exporting keys in every format, so you'll need to ensure that your current wallet software is capable of exporting keys in a format the the new wallet will accept. There are ...

This is not possible. The Bitcoin protocol (currently) has no affordances to control what a recipient can do with coins they receive.

It's a scam, it will never reach 100%. Your money is gone. You can report the theft to your local police but they won't be able to recover your money for you.

For a sender to send to a P2TR address pre activation they must have received that P2TR address from the receiver and so it would be an indirect safeguard to protect the receiver having given out P2TR addresses prematurely. The receiver's funds being vulnerable to being stolen pre activation isn't the sender's direct concern. There are already safeguards in ...

Hot wallets that are not full nodes and as a result don’t have a local database to query, get the address info by querying a centralized service set up by their creators. For example ledger comes with a companion app called ledger live that queries ledger.com for the current balance of each address etc. As a consequence they know which addresses you own by ...
