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.
