The episode with @polkadotnetwork is particularly interesting, and is probably one of the better ways to learn the end-to-end design of Polkadot. I personally find their approach to sharding to be very coherent, especially their approach to data availability and atomicity.

ETH USD going down has two positive effects: 1. Reduces the interest in the space for short-term focused investors; 2. Consequently reduces the interest in the space for teams aiming to quickly raise money on hype from (1) and never ship.

@KyleSamani The problem is that there's no way to build any meaningfully scalable infra without sharding. The only non sharded protocol that can sustain any meaningful load is @SolanaLabs and the sophistication of low level optimizations that @aeyakovenko and the team put in it is insane.

I'm missing some fundamental security property of DPoS. Say Alice stakes $2, Bob delegates her $1M. The system security is $1M+$2. Is it not correct, however, that the cost of double spend is $2+eps, since it is the price at which reasonable Alice will sell her private key?

C++ is truly a magic language. Say you have the following snippet in C++: if (i >= 0) printf("%d\n", i); `i` is int. Can it print a negative number? As a matter of fact it can! See below for the full snippet and the explanation.

3/ With the Rainbow bridge Ethereum and NEAR become fully interoperable. Devs who build on NEAR have access to all the assets on Ethereum, and developers who build on Ethereum can move performance or gas-fee critical parts to NEAR while keeping their Ethereum-native user base.

1/ Another interesting insight from DevCon: while Ethereum invests heavily into building VDFs, initially Ethereum 2.0 will be using RANDAO without VDFs for randomness.

Will be giving a talk at @web3summit this August on challenges in designing sharded blockchains. Will also touch on adoption and usability. Scalable blockchains only make sense if blockchains go mainstream. More projects like @argentHQ need to emerge.
