Proof of Work #64
Hi from LA!
I’ve been at a small conference for institutional investors and crypto people to get to know each other better. The simple takeaway so far has been that institutional adoption is continuing to happen. It’s a slow process that mostly so far has happened in the form of fund investment—a bunch of endowments and a couple of pension funds have put decent-sized checks into crypto focused funds, who are currently deploying that money into a mix of venture-style bets and buying liquid cryptocurrencies. If you hold BTC, this seems like a good reason (among many) to just keep holding it—my sense is that there’s a lot of interest from large institutions, but that they are still somewhat hampered by a lack of regulated custodians, easy tie-ins to the tooling they are used to, etc.
Highlights: Decred lightning network goes live on testnet, Grin’s UTXO set shrank by 15% last week, Loom’s Plasmachain Universal Transaction Signing allows users to seamlessly interact with L1/L2 txs without having to really know or care which they are doing, and Decentraland releases cute Avatars.
No update from: Kadena, Spacemesh, Zeppelin, Theta.

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.
Lightning has struck Decred. We're very pleased to announce that our Lightning Network implementation dcrlnd is now live on testnet. It would appear Decred is the first coin that is not based on Bitcoin Core to go live with LN.
Matheus has released a blog post outlining the tremendous development effort that went into the port as well as the sequence of events that will culminate in Lightning becoming usable on mainnet after our stakeholder voted hard fork which is scheduled to activate on May 9th. There's also a slick video showing LN integrated into our Decrediton GUI wallet.
A new Politeia vote has just gone live to amend the Decred constitution. More specifically to bring it up to date and better describe how the code places ultimate sovereignty in the hands of stakeholders.
