Blockchain seems to be the most talked about tech topic in 2016.

A cryptography powered distributed computing technology that has many potential applications.

Are there any specific ways / guidelines already laid out to leverage blockchain technology for general information security in the data tier of an organization?

Eg: Data integrity etc.

    Don't know of real examples, but block chain seems perfect for logging and non repudiation. Mar 10 '16 at 15:41

    Yes. It definitely seems to be a great solution where sanctity of the logs is paramount. Even non repudiation in case of some critical infrastructure configuration.

It's now 2018 and blockchain doesn't seem to have slowed down. One idea that is potentially gaining traction is using major blockchains as a distributed timestamping service: if you insert an assertion into the blockchain (e.g., the SHA-256 of a file), you can prove that you were in possession of the file at the time that block was mined into the blockchain. (Assuming you do not have compute resources >= 50% of the relevant blockchain.)

  • It's one of the only good purposes of the blockchain (more specifically though, an existing, high-capacity one). Good for augmenting a timestamp authority.

    Another thing is that you can't forge a mined block (sticking to the premisse you own less thatn 50% of the blockchain computer power), thus, integrity is guaranteed.

  • You can trivially forge a mined block. You just can't insert it in the autoritative chain for long without enough hash power. But then, in an internal setting the company probably has 100% of the hash power under control. Jan 17 '18 at 12:32
