Back with another #FreeLoveFriday. Last time, we covered how Mastercoin/@Omni_Layer pioneered digital asset issuance on blockchains. Today, let’s discuss @Chainlink and the vital role it plays in connecting blockchains to the real world.
I have said repeatedly that digital asset issuance is the killer application for blockchains. The next frontier is bringing real world assets to networks like @AvalancheAVAX, but we often face a significant problem:
Namely, how do you get data from the real world onto blockchains and into applications running on them? More critically, how do you achieve that securely and transparently in real-time? Smart contracts are tamper-proof, but they're only as reliable as their input data.
Enter ChainLink in September 2017, with a whitepaper outlining a vision for a decentralized network of “oracles,” entities that inject facts from the external world into blockchains in a suitable format for smart contracts.
Until ChainLink, oracles were trusted and centralized. This is a huge problem for high-value assets and smart contracts. High value projects, such as @CelsiusNetwork, @synthetix_io, @Aaveaave and others depend critically on oracle data.
Back with another #FreeLoveFriday. My first thread focused on what I love about Bitcoin, and features we borrowed for @AvalancheAVAX. Today, let's focus on @Omni_Layer, or as OGs knew it, Mastercoin https://t.co/fXFgmaeUEz

Another #FreeLoveFriday. So far, I’ve covered Bitcoin, Mastercoin/Omni, and last week ChainLink and the importance of decentralized oracles. Today, let’s talk about one of the most fascinating projects in crypto - @MakerDAO
In my thread about Mastercoin, I briefly touched on the vital role fiat-backed stablecoins play in crypto markets, but there’s a catch with them:
The counterparty risk of a third-party holding fiat in reserves.
Enter MakerDAO, which set out to create a decentralized, collateral-backed cryptocurrency, DAI, that would be “soft-pegged” to the U.S. Dollar using the power of algorithms. In crypto tradition, its supporters said trust game theory, not operators.
In 2017, MakerDAO published a whitepaper describing a system where anyone could create DAI by leveraging ETH as collateral to create Collateralized Debt Positions. Essentially, you take out a digital USD loan against your crypto.
The game theory of the system is structured such that DAI issuance is controlled to keep the price pegged to $1.00. In essence, it buffers the fluctuations of the underlying collateral to create a synthetic dollar bill.
