This week, Ethereum successfully completed its “Byzantium” hard fork upgrade. For public blockchains, this is a big deal - thousands of people had to voluntarily agree to switch to new software that is trusted with handling $30 billion. Achievements like this are possible because of a cohesive ecosystem of developers and miners who are committed to a shared vision for the platform. While Ethereum is enjoying it success, other projects aren’t doing quite as well (see Tezos). In the long run, the incentives behind those who build this technology is the most important indicator of how it does or doesn’t progress - are they working to get rich, or realize a dream?
