Executive Summary

This white paper introduces the Blinky Light Thingy (BLT), a novel approach for real-time video authentication in live-streaming environments. The BLT embeds cryptographic messages into the physical environment being recorded, making it difficult to modify the video feed in real-time and avoiding the reliance on specialized trusted hardware. This approach addresses the growing challenge of distinguishing between authentic and generative content, particularly in the context of live video streams where it is becoming more common place for someone to "wear" the filter of another person and perpetuate fraud in what is typically considered a trusted environment. By utilizing Ethereum Attestation Services, a "do-it-yourself" hardware device, and open sourced encoding/decoding software, BLT provides a robust method for verifying both the identity of the presenter and the contemporaneousness (real-time nature) of the content.

Contract Wallets as Containers

There are interesting things happening with account abstraction, but one function I haven’t heard much about is transferring the ownership of a wallet from one user to another. There are a bunch of use cases where this could be useful, I'd like to share my thoughts on how this effects supply chain.

Interobjectivity... ?

I love a good buzz word, especially one that sounds smart; could this be a new narrative that helps us express our intents in a digital world? In exploring where this came from it helped me crystalize my understating of the difference between rules and laws in autonomous virtual worlds. Even though that sounds like a stretch, this is gong to effect the way we do things in the real world sooner rather than later.

Does Knowing Make You Accountable?

In my recent post about supply chain a friend replied in the comments that “I’ve come to the realization that big business doesn’t want that level of transparency, because transparency = accountability.”.  To which my quick counter reply was “Being able to keep transactions confidential is key, but even this creates accountability - so we need an incentive that can outweigh that risk ”.  I then suggested that this would be a topic for my next post, so here it is 😃

Does knowing make you accountable?  What are the real motivations for supply chain transparency.

Why hasn’t blockchain solved our supply chain issues yet?

This is a drum I’ve been beating for many years now - In my opinion using decentralized networks to create trusted and controlled visibility into the supply chains that literally affect the lives of billions of people every day is inevitable; but we are not there yet…. In this post I summarize my latest thinking on the topic.

Digital Twin ≠ Product Token

TLDR – Digital twins are for running simulations and optimizing for future events.  Product tokens are for transferring claims against an asset (ownership, custody, etc) and recording the state of past events.

Product Token Metadata Profiling

Often the topic of AI regarding blockchain comes up, often the topic is misguided…

A blockchain is not a learning system, it is not intelligent (smart contracts aren’t even that smart…). It’s more akin to a data historian, a network that maintains a state, and a record of all previous states. It does not adapt on its own or self optimize - if it did it would undermine the trusted execution.

Attested Sensors & Source Data Synthesis Under Zero Knowledge

TLDR; attested sensors can be used to digitally sign source data at the moment it is collected by a IOT device.  Blockchain can be used to notarize that signature and apply a tamper proof time stamp.  To protect sensitive data from leaving the source, a zero knowledge_  circuit can be used to produce a synthesis of the raw data and generate a proof that the synthesis was done correctly.

Product-Oriented Data Structure

Where is most of the effort going to be for enterprises to get on board with product tokenization for track & trace?  It’s not the blockchain tech - while that part is cool, if we go with the assumption that any decentralized system worth building on needs to be open source and multi-purpose, it’s not going to be the enterprise’s role to develop or operate that network.  It is however the enterprise’s role to lay out clear business requirements that can be used to build modular software (building blocks) to achieve lofty traceability-related use cases.

Wallets vs. Token Metadata

With product tokens we generate a bread crumb trail of metadata that is specific to a given product. In combination with the minting, transferring, and burning of claims on that token the metadata rounds out the full record of the products lineage and data.
