Straightedge

Basics

"A zero-day fork of the Edgeware with different distribution.

We haven't followed this one particularly closely, but it's super interesting to see a live case of a blockchain that launches on mainnet *concurrently* to its fork (is this a first?). The main difference with Edgewere is that Straightedge tweaked the genesis distribution mechanics so that smart contract participation (ie where users are not in direct control of funds) was excluded. The idea was to make it more fair.

A fascinating example of A/B testing from birth in the permissionless world."
