Statement 1 is correct. Blockchain technology operates as a decentralized and transparent ledger that records transactions across a network of computers. The ledger is publicly accessible, allowing anyone to inspect the transactions recorded on it. Additionally, no single user or entity has control over the entire blockchain network, as it is distributed among multiple nodes.

Statement 2 is incorrect. While blockchain technology is best known for its association with cryptocurrencies like Bitcoin, the blockchain itself is capable of recording various types of data beyond just financial transactions. Blockchain can be used to record and verify any type of digital information, such as contracts, identity documents, supply chain data, and more.

Statement 3 is correct. Blockchain technology enables the development of decentralized applications (DApps) that can operate without the need for central authority or permission. Developers can create applications that utilize the basic features of blockchain, such as transparency, immutability, and decentralization, without requiring approval from a central entity.
