Qtum Electrum synchronously updates electrum-related code and releases v0.18.9.
electrum list index out of range
A new repo qtum-electrum-new has been built to add qtum-related features to the latest code for Bitcoin electrum.
In this demo, Electrum developer Chris Belcher shows how to set up and use an Electrum personal server.
Electrum-LTC is a simple but powerful Litecoin wallet. Like its predecessor, the Electrum-Bitcoin wallet, the open source wallet is available on GitHub and anyone can view or upgrade the code.
Wow, wait a minute, why is such a large list only 48 bytes? This is because the range function returns only one class similar to list. This shows that using range saves a lot of space compared to using list directly.
Selection double list range update.
Stock Market . . . Cow! The first half of the public fund performance of the full list out! Stock-based beat the Shanghai index, the most money-making more than 70%.
Bitcoin desktop wallet client Electrum has released a 4.0 beta version, adding several important updates, including support for the Lightning network, nearly a year after the previous version of Electrum, 3.3.8 (last July). In the 4.0 beta version, Electrum mainly added features such as PSBT (partially signed Bitcoin transactions), Lightning Network, watchtowers (暸 watchtowers) and Submarineswaps (subliminal switching). (Github.
With the Daily Relative Strength Index (RSI) now above 55, the index is also moving out of the neutral range. Another positive indicator is that the Daily Moving Average Convergence Dispersion (MACD) bar chart is coming out of a shorter pink bar chart, showing that the selling market is weakening as bull market volumes increase.
According to Cointelegraph, users reported on social media that a group was carrying out a malicious attack on the cryptocurrency wallet Electrum and stealing nearly 250 BTCs (about $937,000)
Because whether it is coin security or fire coins, there will be a lot of currency rise, out of the above list of non-operational range, then stay operational scope, it is necessary to carry out the same type of analysis and comparison.
After pre-cutting, we get an index list of which channels each feature diagram needs to cut out, and then we can follow this list for pruning. The full code for pruning is as follows.

A new repo qtum-electrum-new was built to add qtum-related features to the latest code for Bitcoin electrum.
According to Cointegraph, users broke the news on social media that a group that was carrying out a malicious hacking attack on the cryptocurrency wallet Electrum had stolen nearly 250 BTCs (about $937,000). It was later confirmed by Electrum that the attack included creating a fake version of the wallet to trick users into using password information.
and open the web page, then your wallet may have been compromised. Particularly paranoid people may want to send all BTCs from their old Electrum wallets to the newly generated Electrum wallet.
In December 2018, for the first time, we discovered and alerted an attacker to a messaging flaw that exploited the Electrum Wallet client to force an "update prompt" to pop up when a user transfers money, inducing the user to update the download malware and then carry out a currency theft attack. This "update tip" is not an official act of Electrum, but a phishing attack by an attacker that exploits a message flaw on the Electrum client and the ElectrumX server, which requires the attacker to deploy the malicious ElectrumX server in advance, and the malicious server is localized by the user's Electrum client (because the Electrum client is a light wallet and the user needs the ElectrumX server to broadcast the transaction). At the time of the madness, malicious ElectrumX servers accounted for as many as 71% of the total, and the show doesn't fully count that hundreds of bitcoins have been stolen in this phishing attack over the past year or so. Although in early 2019 Electrum officials said they would adopt some security mechanisms to prevent this kind of "update fishing", such as: 1. Patch Electrum client does not display rich text, does not allow arbitrary messages, only strict messages; Patch ElectrumX server implementation detects Sybil Attack (i.e. witch attacks, malicious servers that send phishing messages) and no longer broadcasts them to clients; Implement blacklisting logic to alert malicious servers outside the Electrum client view; Promote social networking sites, websites, and all forms of communication that exist with users, who should always run the latest version and always only install from official sources (electrum.org), access through security protocols (https), and verify GPG signatures in advance. However, many users of Electrum are still in the older version (less than 3.3.4), and the older version is still under threat. However, we do not rule out a similar threat to the new version. Recently, slow fog technology anti-money laundering (AML) system through continuous tracking found that one of the attackers wallet address bc1qcygs9dl4pqw6atc4yqurzd76p3r9cp6xp2kny has stolen more than 30 BTC, the crime lasted six months, and recently is still active. We would like to remind Electrum users that the new version of Electrum in this Update Tip is likely to be false and that if installed, transfer Bitcoin out in another security environment in a timely manner. At the same time, we call on the vast number of cryptocurrencies exchanges, wallets and other platforms of the AML wind control system black and monitor such as the above Bitcoin address. Finally, identify electrum's official web address.
In addition, small partners who have used Electrum wallets should be aware that with Thecret phrase generated by Electrum, we can recover bitcoin keys on any browser using the Bitcoin Wallet web tool. And Electrum is so secure that there is no evidence that the distributed attack prevention system designed by Dark Wallet will be due to Electrum.
Electrum is a popular software wallet that works by connecting to a dedicated server. These servers receive a hash of the Bitcoin address in the wallet and reply with transaction information. Electrum wallets are fast and have few resources, but by default, it connects to these servers and can easily monitor users. In addition to Electrum, some other software uses public Electrum servers. By 2019, it is a faster and better alternative to BIP37.
The array index that you started to pick is out of range.
We will continue to monitor and track further movements of funds after a recent user submitted a coin-losing incident claiming that the download used an Electrum wallet had been phishing attack, losing more than 700 bitcoins, and that the stolen address had been added to the Devi AML system. It is reported that malicious website (electrumsecure) fake E) fake Electrum website to carry out phishing attacks, guide users to download and use the wallet, in order to steal the user's private key and other sensitive data. Devi Security Labs is here to remind users not to install unknown sources of Electrum wallets, to avoid asset losses.
