DigiStamp Archive Root Hash Publications

DigiStamp protects the integrity of every e-TimeStamp in our Archive. This Archive redundantly protects these timestamps via hash trees signed by every one of our SecureTime TSAs.
This interlinking Archive provides extremely strong, persistently-renewing evidence, but others have claimed that only publication can provide absolute authority. To ensure our systems remain beyond challenge, we regularly publish our root hash values here so that they may be a matter of public record as well.
