Throwback Thursday by BTCMEX
There are numerous software and hardware cryptocurrency wallets today, that are safe and easy to use. But back then the first crypto wallet was a full node, which you had to download the whole blockchain on it. Today, the BTC blockchain is approaching 250 GB.Bitcoin-Qt, currently known as Bitcoin Core, is the first desktop client that allowed regular payments. It’s important to understand, that cryptocurrency is not stored in a wallet, in fact, it’s registered in the system of ledgers on the blockchain. What we know as a crypto wallet is a device or a program that stores private/public keys to access, receive or spend cryptocurrencies.
Bitcoin-Qt was released by Satoshi Nakamoto in February 2009. The private keys for the Qt wallet were stored in a file on the user’s desktop titled “wallet.dat”. While functionality was limited, the Qt wallet did have a few advanced features to it. In addition to sending and receiving coins and incorporating an address book, it enabled the user to digitally sign a transaction, proving that they were the owner of a particular public key.
Courtesy of Gavin Andresen, starting from version 0.9.0, Qt was renamed to Bitcoin Core. “Bitcoin Core” sounds strong and rock-like, which is what you want for something that forms the backbone of the network,” - said Andersen.
Today’s wallets can either be digital apps or hardware-based. Cold storage is a frequent topic of discussion. Cold wallet is an offline wallet used for storing cryptocurrencies. Any transaction initiated online is temporarily transferred to an offline wallet kept on a device such as a USB, CD, hard drive, paper, or offline computer, where it is then digitally signed before it is transmitted to the online network.
The most basic form of a cold storage is a paper wallet. A paper wallet is simply a document that has the public and private keys written on it. It’s printed from the crypto online wallet tool with an offline printer. Another form of cold storage is a hardware wallet that uses an offline device to generate private keys offline. Ledger USB, Trezor and KeepKey are the most popular devices at the market right now.
BTCMEX currently uses a Multi-Signature Cold Wallet - the most secure storage available - to keep the user’s assets safe.
