Limits RegistryPUBLIC RECORD
Limits RegistrySHA3-512, standardized by NIST in FIPS 202 in 2015, produces a 512-bit digest and is designed to offer 256 bits of collision resistance (half the digest length, per the generic birthday-attack bound), the highest collision-resistance target among NIST-standardized hash functions. SHA-3 is based on the Keccak sponge construction, structurally different from the earlier SHA-2 family, providing algorithmic diversity as a hedge against any future cryptanalytic break of SHA-2.

The designed collision-resistance security level, in bits, of SHA3-512, the largest-output member of the NIST-standardized SHA-3 (Keccak) family of cryptographic hash functions, per FIPS 202.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
