Show HN: LogSentinel, blockchain-inspired secure audit trail service

have you all heard of Guardtime?<p><a href="https:&#x2F;&#x2F;guardtime.com&#x2F;cybersecurity-platform" rel="nofollow">https:&#x2F;&#x2F;guardtime.com&#x2F;cybersecurity-platform</a> <a href="https:&#x2F;&#x2F;eprint.iacr.org&#x2F;2013&#x2F;834.pdf" rel="nofollow">https:&#x2F;&#x2F;eprint.iacr.org&#x2F;2013&#x2F;834.pdf</a><p>They seem to be used by the GE predix platform and it looks very similar to the concepts in this thread.<p><a href="https:&#x2F;&#x2F;www.predix.io&#x2F;services&#x2F;service.html?id=1881" rel="nofollow">https:&#x2F;&#x2F;www.predix.io&#x2F;services&#x2F;service.html?id=1881</a><p>that looks licensed from Ericsson which licensed Guardtime.. haha<p>they even go so far as to provide a specialized and hardened hardware device to signing operations at scale.<p>too bad its proprietary!!<p><a href="https:&#x2F;&#x2F;guardtime.com&#x2F;cybersecurity-platform" rel="nofollow">https:&#x2F;&#x2F;guardtime.com&#x2F;cybersecurity-platform</a>

&quot;Guaranteed integrity<p>The log cannot be tampered with without detection<p>Log integrity has been explored in computer science for years. We employ methods recommended by the crypto community, such as hash chaining and timestamping in order to guarantee the integrity of the logs&quot;<p>so they just borrowed one aspect of bitcoin&#x27;s innovation.

Very cool idea. Perhaps you could even push the logs into a real block chain...I think a few alt coins could facilitate that.
