Crypto Wallet Recovery

Did you know that a Blockchain crypto wallet recovery may be possible? Wait,let me explain. There's a custodial and non-custodial type of wallet. Custodial Wallets is the type managed by a third-party exchange or provider. Recovery relies entirely on server-side database access, security identity verification (KYC), or standard account password resets.Recovery of such wallet is quite easy. Non-Custodial Wallets: The user maintains sole custody of the private keys or seed phrase. If a seed phrase is completely missing and no local backup file exists, recovery is mathematically impossible because the data is not stored on a central server. However, due to advanced technology, where a partial loss scenario exists, cryptographic brute-forcing can succeed. For example, if a user loses access to his wallet but still possesses the Wallet ID or even the email used when for the wallet,the architecture changes.If the user completely forgets the password but remembers some guesse...

How to get back my Bitcoin wallet from Martin Bäcklin the creator of bitcoin

So lets be real now. Martin Bäcklin created Bitcoin. A bought 122 000 Bitcoin from www.bitcoin.org which he created. A still have 24 000 Bitcoin left in an phone that a lost. But since a have the key numbers and the purchase receipt 1, 3, 11 from www.bitcoin org it should be possible to get back my 24 000 Bitcoin.

Why use Elligator Swift Encoding - BIP 324?

What is the reason behind using Elligator Swift encoding in BIP-324 ? I gather that it is used to prevent fingerprinting. Is there any other reason ? Thanks from Recent Questions - Bitcoin Stack Exchange https://ift.tt/Wv0tsTx via IFTTT

Why does BIP-110 require a 55% signaling threshold if its nodes reject non-signaling blocks?

During the signaling period, BIP-110 nodes reject blocks that do not signal support. What, then, is the purpose of the 55% activation threshold? From the perspective of a BIP-110 node, would the threshold not always appear to be met, since every block it accepts during that period must already be signaling? Or is the 55% calculated using blocks from the full proof-of-work chain, including blocks that BIP-110 nodes consider invalid? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/382CIDW via IFTTT

Signet Funding Request - Developer Wallet Refill

I am currently configuring and testing a local development environment on the Bitcoin Signet network. My node and local indexing infrastructure are fully synchronized, but I have run into roadblocks utilizing the public web faucets to acquire test tokens.Could an active node operator or community member please send a small amount of testnet coins (sBTC) to my Taproot address? Any amount to cover local transaction fee testing would be greatly appreciated. If there are other ways to get testnet coins please let me know.

Why no widespread support for payment references/additionnal TX Data?

This might sound like a dumb question, but bear with me — it's a real one With traditional bank transfers in a business context, it's standard practice to attach a reference to the transaction (invoice number, customer ID, etc.) so that both parties can reconcile it against their accounting ledgers. I know the recommended practice with Bitcoin is to generate a fresh address per transaction/invoice, which gives you both better privacy (and arguably quantum resistance) and unambiguous reconciliation. Still, that only works when you control the receiving side. The Bitcoin network supports embedding additional data in transactions (OP_RETURN), and EVM chains have the calldata/input data field. So why is it so uncommon for applications — not just browser wallets — to let the sender attach a reference when sending funds? If blockchain payments are ever going to reach mainstream business adoption, this seems as obviously useful as a bank payment reference. I'm ask...

Difference between long-term-fee-rate and discard fee-rate

In the bitcoin-core codebase, it seems that discard fee-rate and long-term fee-rate are used interchangeably when computing the cost of change. Consider the following code excerpts: cost_of_change = discard_feerate.GetFee(change_spend_size) + effective_feerate.GetFee(change_output_size); ref: https://github.com/bitcoin/bitcoin/blob/2990bd773551c835ab0b6b59d85730adab2fd428/src/wallet/spend.cpp#L1182 and also: cost_of_change = effective_feerate.GetFee(change_output_size) + long_term_feerate.GetFee(change_spend_size); ref: https://github.com/bitcoin/bitcoin/blob/2990bd773551c835ab0b6b59d85730adab2fd428/src/wallet/test/fuzz/coinselection.cpp#L96 In both of these snippets, the cost_of_change is being computed, however, one uses the long-term fee-rate while the other uses the discard fee-rate. Are these two terms actually distinct or can they be used interchangeably? To my knowledge, cost_of_change should be calculated using the discard fee_rate, and the long_term fee_r...

Why would forbidding `OP_IF` in Tapscript be a problem?

Following up from Is it a bug that OP_IF is part of the Tapscript opcodes? : BIP110 proposes to forbid OP_IF and OP_NOTIF in leaf scripts. However, old UTXOs are grandfathered in, so the new rules would only apply to UTXOs created after its activation. How could this still create issues for users? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/wWk7KIQ via IFTTT
