Final answer:
Blockchain technology is characterized by being distributed in a shared network, which decentralizes the ledger across multiple nodes, making it globally accessible and secure.
Step-by-step explanation:
One characteristic of blockchain technology that allows a ledger to be spread out and accessible to people all over the world is that it is distributed in a shared network. This means that the ledger is not stored in a central location but is instead replicated across multiple nodes, each node representing a computer participating in the network. This decentralized structure ensures that no single entity has control over the entire network and that the ledger can be accessed from different points globally, ensuring a resilient system that is hard to tamper with or take down. The information on the blockchain is also timestamped and unalterable, further enhancing the security and trustworthiness of the data preserved on the blockchain.
