Question

what is one characteristic of blockchain technology that allows a ledger to be spread out and accessible to people all over the world?
decentralized and not under government control
centralized control for consistency
timestamped and unalterable
distributed in a shared network

Explanation:

Blockchain technology's distributed ledger in a shared network enables global access. Decentralization (not under single - entity control) and distribution across nodes (computers) in a network mean the ledger isn't confined to one location. Centralized control (option B) would restrict access. Timestamping (option C) is about data integrity, not global spread. While "decentralized" (option A) is related, the key for global spread is being "distributed in a shared network" (option D).

Answer:

D. Distributed in a shared network
