Proof of Work #69
Hi from Beijing! This is my last day in the capital—I’m heading to Shanghai now and then back to the US. Almost immediately after my last post, the SEC announced enforcement action against Kik/KIN. Katherine Wu has a great annotated overview, so I won’t go into depth about the specifics of this case, other than to say that I think KIN did a bunch of things they shouldn’t have. In my mind most of the SEC action has been against projects that are “obviously bad” and I don’t think this breaks that mold—that said, I’ve heard there are more worse things in the pipeline. While some projects have been able to work within this extremely hazy framework well, I think a lot of other projects will end up either moving to easier (mostly Asian) jurisdictions, or will simply be copied by teams in these less regulatorily encumbered areas. The fact that jurisdiction still matters at all of course means that these “defi” projects are not sufficiently “de” yet—over the next year or so I think a combination of decentralized namespace (Handshake), decentralized storage (Sia, maybe Filecoin), and an encrypted transport layer (Nym, another secret project I heard about a few days ago, maybe Orchid) may render a lot of these concerns moot by making it possible to anonymously ship truly censorship resistant easy to use defi GUI products, but for now the US seems to be a uniquely bad place to do this.

JZ from Decred
Decred is an autonomous digital currency with a hybrid consensus system. It is built to be a self-ruling currency where everyone can vote on the rules and project-level decision making proportionately to their stake.
It's been a busy week on the proposal front with five currently under discussion on Politeia.
One interesting thing to note regarding the "Block Header Commitments Consensus Change" submitted by Dave is that it's essentially a vote to gauge whether there is support to write up a DCP as well as the actual code to be activated by a future on-chain consensus vote. That way if there is no support on Politeia we don't end up writing a bunch of code that will likely never be used.
Richard has also submitted the follow-up to the "Decred Open Source Research Proposal" for another six months of funding.
Jake has made a formal request to have some trusted community members write up a specification for the Decred DEX.
Ditto has also made a proposal to renew their contract for another six months and has outlined how they will continue to build upon the work that has been delivered thus far.

AJ from Tezos
Tezos is a self-amending blockchain that features formally verified smart contracts, on-chain governance, and a proof-of-stake consensus algorithm which enables all token holders to participate in the network.
The Tezos upgrade proposal, Athens, has successfully been implemented on the Tezos Protocol autonomously. The implementation has proven that Tezos can upgrade to new protocol changes in an automated, decentralized, and self-funded manner. Nomadic Labs proposal attached a 100 XTZ invoice which the protocol automatically minted and distributed after successfully implementing the protocol change. This exercise enables any developer to submit a proposal with their own invoice attached to the proposal.
What’s next? Nomadic Labs, Cryptium, Marigold, and others will submit multiple proposals for Tezos at the end of June.
