All About Lightning Electrum
Now we're going to detail how to create a secure Bitcoin wallet with a cheap USB stick. There are several different wallets that can be downloaded for installation, and in this demonstration we'll use the Electrum wallet. Other lightweight Bitcoin clients follow similar installers.
Electrum can be used for Windows, Mac and Linux, as well as Android. Electrums was originally created in 2011 compared to other software wallets, and one of the biggest advantages is that its server indexes the blockchain instead of downloading the entire Bitcoin blockchain, which makes downloads faster and less downloadable. Electrum also provides many protections for your Bitcoin, including cold storage, allowing you to store Bitcoin offline, and restoring the "seeds" of Bitcoin in the event of a failure (hackers, computer corruption, etc.)
Qtum Electrum is a Qtum desktop light wallet modified from the well-known Bitcoin wallet Electrum. Compared to the current Qtum Core full-node wallet, Qtum Electrum takes up less disk space and takes less time to synchronize chunks, supports multi-signature and hardware wallets, supports cold wallet mode, supports the import of mnomes into mobile wallets, and uses SPV authentication to ensure security.
iOS Wallet Electron (not Electrum!) QT (using the new code base)
Shunto touch melon, open the github of the electrum, we find the following code in the electrum/electrum/ecc.py.
Users of Bitcoin wallet Electrum are facing phishing attacks, according to Johnwick.io. Hackers broadcast messages to electrum clients through a malicious server, prompting the user to update to v4.0.0, and if the user is prompted to install this backdoor-carrying client, the private key is stolen and all digital assets are stolen. At the time of writing, at least 1,450 BTCs worth approximately $11.6 million had been stolen from phishing attacks that forged Electrum upgrade alerts. Devi Security Labs hereby suggests that versions of Electrum below 3.3.4 are vulnerable to such phishing attacks, and users using Electrum Wallet are requested to update to the latest version of Electrum3.3.8 via the official website (electrum.org), which has not yet been officially released v4.0.0, and do not use the link in the prompt message to avoid asset losses.
Almost no Bitcoin wallet can be said to have been involved since the beginning. Electrum announced in 2011 that it had changed course during the downturn in the Bitcoin market. It is now estimated that about 10% of all Bitcoin transactions are reflected in Electrum.
This "update prompt" 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 much as 71% of the total, and the show did not fully count that hundreds of bitcoins had been stolen in this phishing attack over the past year or so.
Bitcoin Wallet Electrum will support the Lightning network in the next release, and its Lightning nodes have been merged into electrum's main branch, according to Cointegraph. Electrum also confirmed that the wallet will be written in-house development Python.
