Alchemix is a DeFi protocol that enables users to create self-repaying loans. Users deposit collateral (DAI) to take out a loan in Alchemix's native synthetic stablecoin, alUSD. Alchemix then uses the DAI deposits and puts them into the Yearn protocol to earn yield and over time, that yield automatically pays off your debt. We were joined by Alchemix co-founder Scoopy Trooples, who gave us a deep look into how the protocol works, alUSD and the ALCX token, and what is coming out soon with V2.

Ethereum Improvement Proposal (EIP)-1559 is a proposal to make several tightly coupled additions to Ethereum’s transaction fee mechanism. Central to the design is a base fee, which plays the role of a reserve price and is meant to match supply and demand. Every transaction included in a block must pay that block’s base fee (per unit of gas), and this payment is burnt rather than transferred to the block’s miner. The base fee is adjusted after every block, with larger-than-target blocks increasing it and smaller-than-target blocks decreasing it. Tim Roughgarden is a Professor of Computer Science and member of the Data Science Institute at Columbia University. Tim did an extensive game theoretical review of EIP-1559 and joined us to chat about what the proposal is trying to do and why, and how it is doing it.
