Together with our client, the Web3 Foundation, we’ve published a blog about our trusted off-chain computing platform SubstraTEE which improves confidentiality, scalability and interoperability of blockchain solutions:

Have a TEE with Polkadot

More technical detail and a live demo with private token transactions is given in the recording of our recent meetup:

This project is open source and the code is available on GitHub

Industrial applications require an increasing degree of trust and privacy protection. Proof of existence, of origination or of a consistent track record gain importance. Trusting the timestamps and the integrity of sensor data can be a crucial requirement, i.e. for using surveillance camera footage as evidence in court.

SCS has set up an infrastructure that proves a concept to add trusted timestamps to sensor data based on a public blockchain. This allows to prove that (sensor) data has been captured at a specific point in time. Such a proof includes existence at certain time as well as prior inexistence, with a time precision of minutes. While it has previously been possible to prove that data existed before a certain point in time, this concept show a way to also prove that data only existed after
a certain point in time.
