/**
 * Gets the latest "block" information for Hedera.
 *
 * Hedera doesn't have actual blocks - it uses a timestamp-based consensus model.
 * To make Hedera compatible with block-based architecture:
 * 1. We fetch the most recent transaction from the mirror node
 * 2. Extract its consensus timestamp
 * 3. Convert this timestamp into a synthetic block using a hardcoded time window (10 seconds by default)
