Bitcoin development Knowledge 1 (Blockchain technology)

The point-to-point network used in bitcoin development knowledge stores all trading history in the blockchain (blockchain). The blockchain is continuously extended, and once the new chunks are added to the blockchain, they are no longer removed. A blockchain is actually a distributed database of disparate client nodes, composed of all participants, and is a record of all Bitcoin transaction history. Once the bitcoin transaction data is packaged into a "block" or block, the transaction is initially confirmed. When the block is linked to the previous block, the transaction is further confirmed. After 6 blocks have been confirmed, the deal is essentially irrevocably confirmed.

When the volume of data increases, the client expects that the data will not all be stored in its own node. To achieve this goal, he introduced a hashing function mechanism. This way the client will be able to automatically eliminate parts that are never available to them, such as some very early bitcoin transactions.

In Blockmeta.info, you can find the latest Bitcoin data chunks for the pending confirmation of the transaction information.

The Bitcoin desktop client is a simple software program that you download to your computer. They provide higher security and control, but require complex settings. There are four main clients to choose from:
1. Standard Bitcoin client BITCOIN-QT
Because of its creator-Satoshi, also known as the Cong client. This is the first bitcoin customer and is constantly being modified. The client is a fully bitcoin network node, which means that it can connect to other nodes although it can mine, but helps to validate and store transaction information. Because of this, you must download the entire blockchain (currently around 3G) after installation, which takes a few hours, and takes a few minutes to sync each time you start the client. Your private key, mathematically calculated data, allows you to use the BTC stored in the Wallet.dat bitcoin address. The client provides options for whether to encrypt your wallet.dat. The client is written by Bitcoin community members, and the development process is by far the most rigorous deliberative and supervised, so it is the most trustworthy. It is characterized by a relatively basic, allowing you to create addresses to receive Bitcoins and send them to any address.

The

Bitcoin client, which provides a range of features, some even more powerful than blockchain. In addition to any Bitcoin client that has standard features, it can manage multiple wallets, manage wallet encryption, import private keys, offline transactions, and even have a feature that allows you to use your Bitcoin address as a public key to sign from your message so that you can create messages that anyone can verify , and cannot be tampered with or forged. But you need to pay for the software to enjoy these conveniences. The armory client does not have its own network capabilities and requires a standard client to run at the bottom. It needs to run with a standard client and requires at least 2 GB of RAM, making it difficult to run on a poorly configured computer.
