Statement 1 is correct. A public blockchain is a decentralized, distributed ledger technology where transaction data is typically transparent and accessible to all participants on the network. It is not controlled by any single entity. Statement 2 is incorrect. While blockchain technology underpins cryptocurrencies like Bitcoin, its applications extend far beyond cryptocurrency. It can be used to record and verify any type of data or transaction, including supply chain management, digital identity, voting systems, and more. Statement 3 is correct. On permissionless blockchains (like Bitcoin or Ethereum), anyone can develop and deploy applications (decentralized applications or DApps) that utilize the blockchain’s features without requiring permission from a central authority.

Blockchain is a decentralized, transparent ledger technology whose applications are not limited to cryptocurrency and on which permissionless innovation can occur.

Blockchain operates as a chain of blocks, where each block contains a batch of transactions, and these blocks are linked using cryptography. This structure makes the ledger highly secure and resistant to tampering.
