Non-goals
Witness does not currently provide:
- proof of content authorship or ownership;
- global ordering across independent Witness networks;
- Byzantine consensus or finality beyond configured threshold signatures;
- content confidentiality if clients upload content elsewhere or include identifying metadata;
- anonymity against an operator that correlates IP addresses, timing, User-Agent strings, application identifiers, or reverse-proxy logs;
- protection from timestamp spam unless Freebird or equivalent admission control is required; or
- tamper-evident operator logs outside the signed tree-head/proof model.
Threshold signatures are not a substitute for independent operators, protected keys, correct client verification, TLS, authentication, or operational backups. Optional federation and external anchors do not change these non-goals.
