Project mention: Arbitrum and Open Source Tools for NFT Development: Unleashing Blockchain Scalability and Innovation | dev.to | 2025-04-25
In parallel with these scalability enhancements, the open source movement has accelerated blockchain innovation. Resources like OpenZeppelin Contracts provide pre‑audited libraries for smart contract development. Open source tools empower developers to iterate quickly, achieve transparency, and establish community governance over projects. Moreover, sustainable open source funding models—such as Gitcoin and GitHub Sponsors—help projects maintain long‑term development and security.

Very complex. https://github.com/makerdao/dss/wiki
The summary appears to be that participants can stake their non-DAI crypto assets into the system, and then borrow an equivalent amount of DAI at current prices minus a haircut (e.g. 80% of what they put in). This is the way DAI is created. Borrowers pay interest on their borrowed DAI. (How does this not result in a negative total amount of DAI? not sure)
If your borrowed DAI falls below another threshold (e.g. 90%) of the value of your collateral, you lose all your collateral. Someone somewhere gets to buy your collateral for only 90% of its dollar value in DAI, and is incentivized to do so because they can then get 100% of the value back on the open market. Therefore borrowers are incentivized to keep their borrowing below this threshold.
That's a pretty standard DeFi loan system; it seems there are also a lot more tacked-on bits which, I assume, prevent it from melting down in a similar way to all the other DeFi loan systems...
