● How will the migration tool from a Bitcoin Core legacy wallet to a descriptor wallet work? Michael Folkson outlines how a tool that migrates existing legacy wallets to descriptor wallets might work. Since the original 0.1 implementation of Bitcoin, wallets have been allowed to remove certain parts of the unsigned transaction from the hash before signing it, which allows those parts of the transaction to be changed by other people such as other participants in a multiparty contract. Bitcoin Stack Exchange is one of the first places Optech contributors look for answers to their questions-or when we have a few spare moments to help curious or confused users. One can make a will by setting up a account so that one's son can withdraw any amount, but with a six-month delay where the account owner can claw the funds back if they are still alive. Go to Nigeria for one day and see the struggle that people have to put up with, link web site with their government and with their money. ● You receive a message saying ‘withdrawal suspended due to risk control’ and have been trying to unlock your account. ● Bitcoin Core Usage Survey: Bitcoin Core developer Andrew Chow created a survey for users of Bitcoin

● Website listing miner support for taproot activation: Bitcoin mining pool Poolin has created a website to help track miner support for activating taproot (including schnorr signatures and tapscript). Pieter Wuille provides an overview of Bitcoin script evaluation in pseudocode including the conditions for additional rules for both BIP16 P2SH and BIP141 segwit. Pieter Wuille describes a variety of nuanced considerations and incentives surrounding transaction propagation on the network concluding that no type of unconfirmed transaction can be trusted and users should wait for confirmations. User Pseudonymous explains that while BIP37 bloom transaction filtering supports unconfirmed transactions, compact block filters have no such consideration and only service light clients with condensed block data since light clients have no way of verifying that unconfirmed transactions are valid. Several other developers, including authors of popular wallets, have been discussing other details of the proposal, including creating an address format for it. This week, BIP143 co-author Johnson Lau posted some suggested changes to sighash flags, including new flags, that could be implemented as a soft fork using the witness script update mechanism provided as part of segwit. Bitcoin is being traded on 8 cryptocurrency exchanges, including Binance and KuCoin. South Korean prosecutors approached KuCoin and OKX, two local cryptocurrency exchanges, to freeze about $67 million worth of bitcoin associated with Do Kwon, the founder of Terraform Labs, who has since disap

Today testnet3 has over 1.4 million blocks and consumes over 20 GB of disk space on archival nodes. ● Discussion of resetting testnet: Bitcoin’s first public testnet was introduced in late 2010; a few months later it was reset to testnet2; and reset again to the current testnet3 in mid-2012. 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. A discussion was started on the Bitcoin-Dev mailing list about resetting testnet again to provide a smaller chain for experimentation. ● Full list of "special cases" during Bitcoin Script execution?

Moreover, because rewards are continually cut in half, to make mining financially worthwhile, miners have to process more transactions or reduce the amount of electricity they use. Over the past few decades, consumers have become more curious about their energy consumption and personal effects on climate change. Despite last week's fall of around 11%, Bitcoin's market cap rose to $529bn, and the cryptocurrency's dominance was at 46.48%, up 0.19% over the day. Last but not least, there are the new Coin Stocks. In this monthly feature, we highlight some of the top-voted questions and answers posted since our last update. For more information, place the cursor over the Connection Type field name to see the tooltip shown below. 163 replaces the Direction field in the GUI peer details area with a Connection Type that displays both the direction and the type of peer connection. The functional details are not covered in the paper, but the sourcecode is coming soon. Are you TheDAO attacker? Developers are strongly encouraged to write unit tests for new code, and to submit new unit tests for old code. Q40. How do I identify a specific unit of virtual currency? Customers will deposit bitcoin or fiat currency into their accounts and then place different order types that are recorded on an order book managed by the exchange.
