20170919 Hash Algorithms: Differences between SHA-1, SHA-2, and SHA-256.
The hash algorithm, to be precise, cannot be called an algorithm, and it is one of the families of cryptological hash functions defined by the National Institute of Standards and Technology. Most of the SHA series hash algorithm standards commonly used in blockchain today are designed by the Society. Includes SHA-1, SHA-224, SHA-256, SHA-384.
With the hash function, you can save data on the Internet as a fixed-length string. One method is SHA-256 (security hash algorithm-256 bits), SHA-256 is a successor to SHA-1, sha-1 output is 160 bits.
Substitute SHA 256 and RIPEMD160 (a different hash function) and eventually get the Bitcoin address.
Bitcoin wallet Electrum official Twitter announced that the next version of Electrum will support Lightning online payments. Its lightning node implementation has been consolidated into the main branch of Electrum. Electrum also confirmed that the wallet will adopt a new implementation of in-house development written using Python.
Johnwick.io found that hackers launched a denial-of-service (DoS) attack on a well-known wallet, Electrum server. Hackers used a botnet of more than 140,000 computers to attack Electrum's nodes and simultaneously deployed malicious nodes. When a user connects to these malicious nodes and sends a transaction using an older version of Electrum, the user is prompted to update the Backdoor Client. If the user installs the client as prompted, the private key is stolen and all digital assets are lost. Millions of dollars of digital currency have been stolen, according to Electrum officials. Devi Security Labs recommends that users of Electrum Wallet update to the latest version of the client via the official website and never use the link in the prompt message.
Once everything is set up, you can use Electrum. Have Fun.
One of the oldest Bitcoin wallets, Electrum, will support the Bitcoin Lightning Network.
According to Johnwick.io, we will continue to monitor and track the further flow of funds after a recent user submitted a coin-losing incident claiming that the download used an Electrum wallet had been phishing and that more than 700 bitcoins had been lost, and that the stolen address had been added to the Devi AML system. It is reported that malicious websites (electrumsecure) fake Electrum website phishing attacks, to 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.
