pub const EMPTY_ROOT: Bytes32;Expand description
Digest of the empty byte string, i.e. SHA-256 of "".
Used wherever an “empty” Merkle accumulator or trie root must be represented canonically (for example
pre-DFSP roots and empty subtrees). The value is fixed by the protocol; clients must not substitute
ZERO_HASH for this purpose.
Proof obligation: tests/test_protocol_constants.rs
compares this constant to chia_sha2::Sha256 of the empty input so we satisfy BLK-005 without
recomputing at runtime in production code.
