NEAR Protocol is a leading smart contract platform that aims for simplicity, security and scalability. NEAR was one of the first sharded blockchains and allows deploying smart contracts using Web Assembly on currently four different shards. NEAR's sharding design, Nightshade, splits the blocks into different segments, which allows for great scalability without negatively impacting user and developer experience. Since, its launch NEAR has evolved into one of the most active smart contract ecosystems. Illia and Alex, co-founders of NEAR, joined us to chat about the NEAR's protocol design and recent advances, such as the launch of Aurora, NEAR's EVM shard. We also discussed how their sharding solution works and how it can scale to support a massive amount of users and applications.

Agoric is an Proof-of-Stake blockchain built on the Cosmos-SDK that allows developers to create secure smart contracts written in JavaScript. It offers developers safe, reusable DeFi components and built-in economic primitives like a stablecoin, while connecting to the larger blockchain ecosystem via IBC. Besides covering the Agoric platform, we dove into the long prehistory with Agoric CEO Dean Tribble. Dean and his co-founders have been working on smart contracts and secure computing for decades, long before cryptocurrencies were invented, and a lot of that work shaped the Agoric platform today. We talked about underlying design principles like the Object Capability Security Model, but also the tradeoffs between Ethereum's model of scaling on a single chain versus the Cosmos model of sovereign chains interoperating asynchronously.
