8 Quick Stories You Did not Know about Bitcoin > 자유게시판

What that means in terms of investing is that bitcoin and other cryptocurrencies can be useful as a hedge against other investment classes, and also provide a useful diversification function in traditional investment portfolios. This means that you cannot fund your Binance account using fiat currency. Copy the wallet address provided by Binance and use it to transfer your funds from your external wallet or bank account into your Binance account. 2063: https://youtu.be/ new functions for creating sweep transactions have been added, replacing functions from the UTXO Nursery that is "dedicated to incubating time-locked outputs." These new functions accept a list of outputs, generate a transaction for them with an appropriate fee that pays back into the same wallet (not a reused address), and signs the transaction. A discussion was started on the Bitcoin-Dev mailing list about resetting testnet again to provide a smaller chain for experimentation. The sweep transactions set nLockTime to the current block chain height, implementing the same anti-fee sniping technique adopted by other wallets such as Bitcoin Core and GreenAddress, helping to discourage chain reorgs and allowing LND’s sweep transactions to blend in with those other wallets’ transactions. This would also allow the easy management of testnet disaster drills such as large chain reorganizations.

● 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. ● Upgrade to Bitcoin Core 0.16.3 to fix denial-of-service vulnerability: a bug introduced in Bitcoin Core 0.14.0 and affecting all subsequent versions through to 0.16.2 will cause Bitcoin Core to crash when attempting to validate a block containing a transaction that attempts to spend the same input twice. BIP133 (implemented in Bitcoin Core 0.13.0) allows a node to tell its peers what its minimum feerate is so that those peers to don’t waste bandwidth by sending transactions that will be ignored. Even if you never connect to your node over the Internet, having an open RPC port carries a risk that an attacker will guess your login credentials. Some of these schemes can’t use the default hash function libsecp256k1 uses, so this merged PR allows passing a pointer to a custom hash function that will be used instead of the default and which permits passing arbitrary data to that function. RPCMiner is far easier to run - you simply click an icon and enter some data - and both have very rudimentary, text-based interfaces.

Desktop wallets are more secure and safe, never store your coins online in an online wallet or exchange. The accounts system was added in late 2010 to allow an early Bitcoin exchange to manage their user accounts in Bitcoin Core, but it lacked many of the features desirable for true production systems (like atomic database updates) and it often confused users, so removing it gracefully has been a goal for several years. FAIELLA, 52, of Cape Coral, Florida, and SHREM, 24, of New York, New York, are each charged with one count of conspiracy to commit money laundering, which carries a maximum sentence of 20 years in prison, and one count of operating an unlicensed money transmitting business, which carries a maximum sentence of five years in prison. If this option is present, you should remove it and restart your node unless you have a good reason to believe all RPC connections to your node are encrypted or are exclusive to a trusted private network.

● Optech dashboard: a blog post by Marcin Jachymiak introduces the live dashboard he developed for Optech during his internship this summer, providing not only an overview of what information the dashboard makes available to you but a description of how he built it for anyone who wants to independently replicate the data or otherwise extend the dashboard using their own full node. The basic mechanism is that the authorized spender or spenders for an address generate scriptSigs and witness data (including their signatures) in much the same way they would if they were spending the funds-except instead of signing the spending transaction, they sign their arbitrary message instead (plus some predetermined extra data to ensure they can’t be tricked into signing an actual transaction). In BIP143, segwit preserved all of the original Bitcoin 0.1 signature hash (sighash) flags but made some minor (but useful) changes to what data wallets include in the hash that made it harder for miners to DoS attack other miners and which made it easier for underpowered devices such as hardware wallets to protect users funds.
