Chakra Chain Technologies wants to use a distributed ledger so that several banks in an IFSC can share a single tamper-evident record of trade documents without relying on a central database owner. Which feature of blockchain most directly supports this need?

Blockchain's cryptographic chaining and replication of the ledger across participants makes records tamper-evident and hard to alter unilaterally. This lets several banks share one trusted record without a central owner. Options describing a single administrator or a central server contradict distributed ledger design.

  1. ARecords are chained cryptographically and replicated across participants, making unilateral alteration difficultCorrect
  2. BA single administrator can edit any past entry to correct errors
  3. CData is stored only on one central server for speed
  4. DTransactions require no validation by participants

Explanation

Blockchain links blocks using cryptographic hashes and replicates the ledger among participants, so altering past records unilaterally is hard. The other options describe centralised control, which is the opposite of the stated need.
