In addition to isolated witnesses, the new bech32 address format based on isolated testimonies will be adopted for the first time in 2018. These addresses do not start with 1 or 3, but start with "bc1" and are ideal for isolating witness transactions. Transactions from these addresses take up less capacity and are therefore cheaper. Wallets such as Coinomi, Electrum, and Wasabi use this new address format directly.
For example, how many users are using Bitcoin? We don't know. We can calculate how many addresses there are and how many tokens are on them. But we don't know how many. A person can have many addresses, and so on.
In December 2018, Slow Fog first discovered and alerted an attacker to a messaging flaw using the Electrum wallet client, forcing an "update prompt" to pop up during a user's currency transfer operation, inducing users to update and download malware to carry out a currency theft attack, according to Slow Fog. Although electrum officials said in early 2019 that some security mechanisms would be in place to prevent this "update phishing", many users of Electrum are still in the old version (less than 3.3.4) and the old version is still under threat. However, we do not rule out a similar threat to the new version.
Shunto touch melon, open the github of the electrum, we find the following code in the electrum/electrum/ecc.py.
Nested Segwit and native segwit, a compatible isolation witness, a native isolation witness. The difference between the two is quite large, at this stage try to use compatibility, that is, the address beginning of 3, because the large number of wallets and exchange support. The native address starts with bc1, which is not supported in many wallets. It is recommended that wallets that flow more frequently use the original address beginning with 1, and Tuen coins with compatible isolation witness beginning with 3. To see the actual situation, if it is miners, there may be many places to transfer money to miners, miners do not care about the other side of the fee, but concerned about the maximum compatibility, 1 is more appropriate at the beginning, if it is to do transactions, can use compatible isolation witness or better.Tags: electrum native segwit
If you haven't set up Electrum Wallet to be compatible with your phone wallet, you can use the private key to recover the Electrum wallet on your web wallet. Select Wallet - "Private Key" - "Export" on the Electrum wallet and you will export the file qtum-electrum-private-keys.csv or copy only one private key. Select Recover from WIF on your web wallet, paste the private key, and select Confirm. Check that the wallet address is correct. You may need to use Dump as a Key File to save the key file.
On the other hand, a forced closure means a unilateral closure. Use only in emergency situations where the AINQ node has failed or been hacked. This process takes approximately 5 days and requires 750 confirmations in the blockchain, or the same confirmation. If you use this option, you will need to restore your wallet to a seed-compatible wallet, such as Electrum, once you have the necessary confirmation so that you can see the money.
Electrum 0.18.8 is available for details at github.
On August 8, Electrum, a BTC wallet service provider, posted on Twitter that its servers were facing an ongoing DoS attack.
In contrast, another wallet, Stratis Electrum, is a simplified trading client.
After encrypting the information with the private key, you can get a piece of information signature, and in the case of known public key, signature, original information, you can verify that the change of signature is generated by the corresponding private key. This forms the cryptographic basis for BTC to transfer and verify transactions.
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 Wallet is fast and has 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.
