The blockchain browser is the main window for browsing blockchain information, and the content recorded in each block can be viewed from the blockchain browser. Usually digital currency users will use the blockchain browser to query the transaction information recorded in the block.
Each blockchain has its own blockchain browser, and users cannot perform cross-chain queries through the blockchain browser. For example, the browser of the Bitcoin blockchain can only query the Bitcoin block, and the Ethereum can only query the Ethereum, but cannot query the block of the Ethereum through the Bitcoin blockchain browser. Blockchain browser development company introduces what is a blockchain browser?
In order to facilitate users to query the content on multiple blockchains, some websites will centralize the blockchain browsers of multiple chains on one website, so that users can switch freely among multiple blockchain browsers. It should be noted that the ability to freely switch block browsers does not mean that digital assets can be traded across chains. The blockchain browser only provides block query function.
The blockchain is a public ledger maintained by each miner node and stored in each decentralized node around the world, because each node and miner must follow the same accounting transaction rules, which are based on cryptographic algorithms. Non-credit, and each transaction requires the approval of other users in the network, so there is no need for a third-party intermediary structure (such as a bank) or endorsement by a trusted agency.
In a traditional centralized network, an effective attack on a central node (such as a payment intermediary third party) can destroy the entire system, while in a decentralized network such as a blockchain, an attack on a single node cannot be controlled or destroyed. In the entire network, mastering 50% of the nodes in the network is just the beginning of gaining control.
The core of blockchain technology is that all currently participating nodes jointly maintain transactions and databases. It makes transactions based on cryptographic principles rather than trust, so that any two parties who reach an agreement can directly conduct payment transactions without the participation of a third party.
Technically speaking, a block is a data structure that records transactions and reflects the flow of funds in a transaction. The blocks of transactions that have been reached in the system are connected together to form a main chain, and all nodes participating in the calculation record the main chain or a part of the main chain. A block contains the following three parts: transaction information, the hash formed by the previous block, and a random number.
The transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of the electronic currency, etc.; the hash formed by the previous block is used to connect the blocks to realize the past Transactions are arranged in order; random numbers are the core of transactions, all miner nodes compete to calculate the answer of random numbers, and the node that gets the answer the fastest generates a new block and broadcasts it to all nodes for update, thus completing a transaction.
