Technical Concepts

Proof of Stake

Proof of Stake (PoS)

Consensus mechanism where validators stake assets to secure a blockchain

Definition

Proof of Stake means consensus mechanism where validators stake assets to secure a blockchain. In DeFi, the concept matters because it affects risk, return, liquidity, governance, or execution assumptions.

Example

Ethereum validators stake ETH to participate in consensus and can be slashed for serious violations.

1

What to check

Identify which contract, validator, oracle, admin key, or process can still affect outcomes. The main checks are: Validator slashing; Centralized staking providers; Protocol or client bugs.

Risks to Consider

  • Validator slashing
  • Centralized staking providers
  • Protocol or client bugs

🧭 DeFi Moneygames: Assessing risk and avoiding wreckage

Food-based social moneygames are all the rage in decentralised finance. Today, I wanted to write a quick piece to provide some context on them, as well as some tips for those who want to. I’ll not pass moral judgement on such projects, I leave it up to you. The launch of Yearn Finance last month was probably the most significant event of the year for DeFi. If you are not familiar at all with Yearn, check this intro: YearnFinance - DeFi on autopilot? - it will be helpful to better understand today’s article.

DeFi Bullshit Detector: Red Flags With Claude

The DeFi Bullshit Detector is a Claude instance dedicated to DeFi research, set up to check a protocol’s marketing against onchain reality. In the Arena this week, I tried something different: instead of doing things onchain as usual, I wanted to show how to set one up, and the results were impressive. In 1h15, we were able to setup a new Claude instance from scratch, have it write its claude.md file with our instructions, install the necessary tools to query onchain data, and perform a test analysis on ThGold which returned many critical red flags, several of which were not previously discovered by another researcher as far as I could see.

Why Polaris? The Stablecoin we needed to build

Stablecoins have won: they’re the backbone of DeFi liquidity, the unit of account for onchain trades, and the most outward-facing DeFi usecase. By every adoption metric, they’re the most successful primitive we’ve built. And yet, something went wrong. The dominant stablecoin models have drifted from their original promises. What started as experiments in decentralized money has quietly become a collection of TradFi dependencies wrapped in smart-contract aesthetics. The foundations deteriorated as the TVL climbed. The most popular Stablecoins remain tokenized T-Bills that do not forward their yield, namely USDC and USDT.
