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.
As these networks grow to handle more value, “Oracle Extractable Value” goes up and oracle security becomes a significant issue.
In 2018, ChainLink commercialized “Town Crier” technology built by @initc3org at Cornell. Town Crier uses Intel’s SGX technology to harden their defenses against tampering and reduce the trust required of the oracle operator.
@SergeyNazarov and team have done an amazing job in overhauling what we knew about oracles, strengthening smart contracts, and spurring healthy competition with more oracle projects.
So what’s next? I think one of the biggest challenges facing oracles is how to deliver granular, real-time data at low cost. I have some ideas for how to solve these for good, but I’ll save them for another thread.
Let’s just say that Avalanche subnets and ChainLink’s decentralized architecture are a very good match, and that’s one of the many reasons why we have forged a partnership.

I'm sure someone else has explained this, but it is just so cool and I want to explain how this works.


So Curve is awesome for swaps between similar assets, right? The fact that they trade very close to each other is a key part about how Curve works, using it's custom swap invariant function.

That's step 1

Step 2 is that Synthetix is awesome for creating "synthetic assets" (aka synths) which are assets that trade like other assets, that are backed by another, entirely different asset. Basically, a plastic banana that I can buy and sell like a real banana.

Synthetix has a feature that lets you swap between any two synths with zero slippage and a flat fee. That's because it is simply converting the sythentic asset into another synthetic asset, the backing for the synth doesn't change it just uses a different price oracle now.

This is important. Absolutely no slippage, at any size

Swap $1m sUSD for $1m sBTC? flat 0.3% fee

Swap $10m sUSD for $10m sBTC? flat 0.3% fee

swap $100m sUSD for $100m sBTC? Well, there isn't that many synths in Curve, yet but you get the point. The only limit is the pool depth
