A blockchain is a digital database that stores information about transactions (such as money transfers) in a series of records (blocks). These records are encrypted and linked together, giving them a high level of security and unquestionability.
History of Blockchain
Blockchain was created in 2008 as part of the cryptocurrency Bitcoin. Its creator is an unknown person or group of people operating under the pseudonym Satoshi Nakamoto. Blockchain allows data to be stored in a decentralized network, where data is stored in blocks (hence the name blockchain) that are linked by cryptographic functions, ensuring that the data is neither alterable nor erasable. This means that once the data is stored on the blockchain, it cannot be altered or tampered with.
Blockchain is becoming increasingly popular not only for digital payments, but also as a tool for various other applications such as contracts, identity management, data authentication, etc. Currently, blockchain is used in many industries, including banking, logistics, healthcare, education and other areas.
What tools or applications will allow me to view data on the blockchain?
1. Block Explorer: these web applications allow you to search and view information about transactions, addresses, and blockchains.
2. Cryptocurrency Trading Platforms: These platforms such as Coinbase, Binance, and Kraken provide information on the prices and trading histories of various cryptocurrencies.
3. Blockchain Analytics Tools: These tools, such as Glassnode, Chainalysis, and Nodestats, help analyze and extract information about transactions and accounts on the blockchain.
4. API: Many blockchain networks provide publicly available APIs that allow programmers to retrieve and process data from the blockchain.
5. Dashboards: these tools, such as CryptoDashboard and TokenAnalyst, provide interactive dashboards for viewing and analyzing blockchain data.
These tools allow you to get information about transactions, addresses, and other indicators such as the number of tokens in circulation or total transaction volume. Additionally, many blockchain networks provide publicly available APIs that allow programmers to retrieve and process data from the blockchain.
