If you appreciate this newsletter, thank ConsenSys

I'm thankful that ConsenSys has brought me on and given me time to do this newsletter.

Editorial control is 100% me.  If you're unhappy with editorial decisions, blame me.

Shameless self-promotion

Here’s the link to share:  https://steemit.com/ethereum/@evanvanness/week-in-ethereum-june-21-2018 This issue is on Steem because 1) the issue is late and Steem is faster than Tumblr and 2) because I'm going to donate the Steem and SBD I get from this post to the victims of the Ellicott City floods, which is a fundraiser from the Bitcoin Podcast.

Most of what I link to I tweet first: @evan_van_ness

I also have an Ethereum podcast on the Bitcoin Podcast network.

This newsletter is supported by ConsenSys, which is perpetually hiring if you’re interested.
