      The brightest star in the sustainability sky is @gitcoin. Two successful rounds of quadratic funding for #Ethereum prove the model. I am excited to see @owocki expand focus and encourage the gitcoin community to tap into some of the #Zcash project's new "Major Grants" funding.

      Innovation. Enough is enough. We don't need a better world computer. We need to make the one we already built, the one has *all* the developers, usable by the masses.

      Eth2 is (finally) coming and it looks like it will be worth the wait. Unlike most other mainnet POS networks, Eth2 is designed to support >1M validators. This, combined with the relatively low staking requirement, will be a boon for decentralization.

      Transition to Eth 2 isn’t going to be fast. The migration will be eased by layer two solutions like the @optimismPBC Optimistic Virtual Machine. The OVM allow contracts written for Eth1 to work on Eth2 straight away.

      We have built a "composable" ecosystem of powerful technology, and now it's time to focus on usability. Better UX will help us find the use cases that will unleash the transformative potential of the technology to the parts of the world that need it most.

      To make "crypto usable for normals", social key recovery and friendly naming are pre-requisites. "Lose your phone, lose your money" is a non-starter. So is sending money to a long base58 encoded string, where one typo and poof your money is gone.

      The @argentHQ team has a clear lead on usability. I'd like them to raise a series A led by a top notch VC and use the proceeds to scale. They should continue to flesh out their product vision without compromising on UX while also investing in "full stack continuous security".

      #DeFI crossing $1B is a fun milestone. "Money legos" was the buzz of the show. @shalaburroughs called it “money jenga”, and given my tenure in software security I couldn’t agree more. This house of cards will collapse. The only questions are when, to what extent, and who loses?

      Apps like @Dharma_HQ have great UX, but tempt noobs into the ecosystem, promising “7.5% APR on your USD”. Appealing compared to the .02% yield on fiat savings. The naive consumer isn’t aware of the risks at each layer of the stack, and the security FAQ only covers a few of them.pic.twitter.com/gY8CXTearP

      Security. Everybody cares. Big improvement over web2. But they naively think that having @trailofbits audit their smart contract once solves the problem. Wrong. Formal verification and compartmentalization like that provided by @agoric's secure ecmascript (SES) goes further.

      .@trailofbits performs formal verification! It's a fallacy that simply using 1 technology will keep you safe: it's all about the security properties you define and how you prove them. Here's a good interview where I dig into the details:https://defiprime.com/defi-smart-contract-audits …
