In this demo, Electrum developer Chris Belcher shows how to set up and use an Electrum personal server.

Versions of electrum Bitcoin wallets can be synced automatically on different computers. If users want to use other client programs or online services in the future, they can easily export keys or import them into cold wallets.

Chain News, lightweight Bitcoin Wallet Electrum announced that the next version will support Lightning network payment, implemented using Python, Electrum as a Lightning network node, wallet users do not need to run lightning network nodes to make payments, electrum lightning network nodes have been merged into the Electrum master branch.

Electrum is free software used by many cryptocurrencies websites, including merchants and exchanges, to store bitcoins. Anyone can run an Electrum server, and the software supports hardware wallets such as Trezor, Ledger, and Keepkey. Enhanced features include multi-signal and the ability to sign transactions using cold storage devices that are not connected to the network.

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 many as 71% of the total, and according to incomplete statistics, hundreds of bitcoins have been stolen in this phishing attack over the past year or so.

In addition, MalwareBytes also pointed out that in the first quarter of this year, Bitcoin (BTC) holders who used Electrum wallets on Mac computers lost more than $2.3 million worth of stolen bitcoins, which were stolen by a Trojan horse version of the wallet. Up

Turn on the fan, and not cool, not only do not solve the heat, hard wind hit the face like a knife scrape, the skin is blowing more and more dry.

Well-known Bitcoin wallet Electrum "update phishing" currency theft continues.

circuit. A closely related idea is to connect the Electrum servers in the onion routing network together. When creating such a scenario, care should be taken to avoid time correlations that link addresses together, otherwise the server might use the fact that the requested addresses are time-close to each other.

The new version of the wallet will also include undersea switching, which allows BTC to pass from the Bitcoin blockchain to the payment channel network LN. For this novelty, Electrum is based on Boltz technology. Electrum will charge a commission for this service.
