TL/DR : Ethereum proposes to change the rules entirely. If the rules Ethereum plays by prove to be valid, major innovations are on the horizon. For early crypto start ups, the rules seem to be working…

Proof by Contradiction: An Example

In 300 BC, Euclid published his work Elements, giving us the postulates that are the foundation of geometry. Among them was his fifth postulate: parallel lines exist

“Innovation comes from saying no to 1000 things.”

Steve Jobs

The past decade of my career has been spent focused on enterprise, first in supply chain with time in procurement, finance, quality, manufacturing, strategic sourcing and employee training. This experience was followed with a brief stint as a developer for a startup in 2017. Now, back in enterprise, at the intersection of supply chain, operations, technology, etc., I find myself with a unique vantage point at the convergence of these industries.

As an individual, I’m enthusiastic about discovery and innovation, from the fundamentals of mathematics to the incremental improvements in…

As I sit on a flight home from Seattle on Wednesday March 4th, I am left with no absence of topics to ponder. From the virus, to the interest rate cuts, to the fact that a nation of 1.3 billion people are now legally allowed to trade cryptocurrency, a lot has happened in the past few days. However, what changed? Who changed it? And who actually agreed to these changes? How did we decide on this timing? Even for a pandemic, I do not find these questions entirely crazy. It is really only crazy that one cannot answer these questions…

TL/DR: A piece about the history of cryptography, how it works, zero knowledge proofs, and the future potential impact. Having a basic knowledge of blockchain would be helpful; however, this is intended to be relatable (and enjoyable) to wide audience.

A Short Story About Transactions

As a company, Visa dates back all the way to 1958. In those days, a temporary paper card was provided with a preset limit, and vendors settled transactions later at the bank. Next, mechanical embossing machines accomplished a similar feat. Still, vendors had to spend several minutes physically calling into Visa to verify and approve transactions that even then had to be later settled at the bank. It was not until two decades later, in 1979, when electronic payment terminals came about. …

A Brief History & Definition

In 1996, Nick Szabo first postulated his idea for smart contracts, as

“…a set of promises, specified in digital form, including protocols within which the parties perform on these promises.”

At the time, a fully decentralized “protocol within which the parties perform on these promises” did not yet exist. Certainly, several types of “contracts” or “agreements” are already built into existing systems. …

Part 2: Continuing a look at why generalized state channels are going to help build the decentralized future and how to build them. Part 1 can be found, here.

Please note this is a thorough but not 100% complete or definitively secure methodology of how to build out generalized state channels. Code is not meant for immediate use. Also, libraries and tools used in this tutorial may have been updated since this post was published, please be mindful.

To continue from Part 1, having opened a state channel between Party A and Party B, we will be going over:

A Deep Dive into Managing ERC721 Assets

TL;DR

Basically, since ownership of ERC721’s is based on the ownership of a unique index or id, the fundamentals of token creation and transfer need to be extrapolated to accommodate that case. Also, the latest full implementation includes a safeTransferFrom() function that checks for implementation of a standard interface prior to transferring tokens.

ERC721 Tokens

I have seen a lot of material around the interest in ERC721’s as non-fungible tokens that can hold metadata, but the depth of the material that I have found has left me looking for more details. My interest in ERC721’s started back at EthDenver back in February —…
