ELECTRUM introduction
A popular lightweight bitcoin wallet that verifies bitcoin transaction information based on the SPV principle proposed by Satoshi Nakamoto. It's feature-rich, open-source, and security-focused. The installation file is only 30MB, and the program operation does not need to download the blockchain data file. The query function of the wallet uses the SPV verification mode and is in a random server list. This means that very little trust is required in third parties when verifying payment information, but is not as secure as a Bitcoin Core full node Bitcoin wallet. High security. Wallets use new change addresses after each transaction, and this rolling way of using addresses makes snooping on your balance and payment history much harder. The official wallet Bitcoin Core also requires a new Bitcoin address for every payment. Restoring your wallet is easy with just one backup. Support HD mode (hierarchical deterministic wallet, BIP32), restore all Bitcoin addresses through the security seed; you can use the easy-to-remember security seed to restore your wallet at any time, the security seed is a short English sentence that can be quickly remembered . Support multi-signature, users and enterprises with high security requirements can use multi-signature to manage Bitcoin. Support two-step verification function Tow Factoring Authentication, enabling two-step authentication can also make it more difficult to steal your bitcoins. Support Trezor, Bwallet and other hardware wallets, which can facilitate the operation of hardware wallets. You can also put the program files in a USB flash drive to carry with you. Cold storage is supported, and transactions can be signed offline without a network. Available on the Tor network. This wallet lets you set up and use Tor as a proxy. This prevents attackers or internet service providers from associating your payment with your IP address. The downside is that use needs to connect to the SPV query server, and this central server can link your payment history together and record your IP address. The English interface is displayed by default on the first run, and it needs to be set to Chinese after entering the wallet.
