Expanding on this, colors are basically just a mental construct, it is how your brain interprets specific wavelengths, my colors may not be the same as yours

If one of your cones doesn't work, your perception of "reality" is skewed, though not really any more or less"true"
Pain is just your brain's response to damaged nerve cells which send electrical signals that are routed by your peripheral system to the central nervous system (specifically your nrian) to stop whatever action causes damage
Your brain simulates "pain" to incentivize the rest of "you" to fix this problem, if this didn't happen (no pain threshold), humans would die far more easily without realizing it
en.m.wikipedia.org/wiki/Congenita…
Pain isn't an external thing, and what is extremely painful for one person may be nothing to another (spicy food isn't a flavors, it's just pain receptors)

There is no truth here, only perception from a small subset of information of the external world interacting with us
Someone also brought up a good point that our brains tend to "fill in the details", aka remembering something that didn't actually happen

This is why eye witness accounts are not reliable, especially when under traumatic stress
The point I am getting at is that definitive truth in it's ultimate form is fundamentally incompatible with human being, it isn't what keeps up alive as a species

Therefore our collective perception of truth is ultimately what we're after, social consensus of what is legitimate
If we can generate definitive truth, but nobody recognizes it as such, how much value is it providing? I'm not saying 1984, but I'm speaking from a position of pragmatism over straight raw idealism (the road to hell is paved with good intentions)

Trust is an infinite regression
One day when everything of value, everything we interact with, and even the way humans are created are entirely digital, deterministic, and 1,000,000x the mental bandwidth, this can change and we can injest raw data ourselves

Until then, social consensus is our "truth"
I really don't know where I was going with this thread, but I thought this was interesting on the topic of truth, have a good day frens

1/ With the launch of Uniswap V3, I'm seeing questions regarding the differences between DEX-based TWAP oracles and Chainlink Price Feeds

There are four primary differences
1. Freshness/accuracy
2. Market coverage
3. Security scalability
4. Feed diversity

$LINK $UNI
2/ For context, the naive way to use Uniswap (or any DEX) as a price oracle is to take the spot (aka current) price

This method is extremely vulnerable to flash loan attacks and millions have been lost this way

Even Uniswap doesn't recommend you use their protocol in this way
3/ To prevent this (specific) issue of flash loans, Uniswap v2 and v3 offers Time Weighted Average Price (TWAP) oracles

TWAP is a way to calculate the mean price of an asset during a period of time

e.g. "1 hr TWAP" is the average price of an asset over a specific hour of time

1/ #Chainlink is blockchain agnostic meaning it supports not only every baselayer L1 network, but also every L2 scaling solution

Optimistic Rollups, zkRollups, Validium, Plasma, State Channels, Sidechains, etc

But with @arbitrum, well now that's something special
2/ Arbitrum is an Optimistic Rollup L2 scaling solution that has already integrated Chainlink Price Feeds into its testnet

These data feeds will power @Bancor, @MonteCarloDEX, and a number of other L2 projects on Arbitrum once it launches on mainnet
offchain.medium.com/chainlink-orac…
3/ What makes the combination of @Chainlink + @Arbitrum truly unique is regarding that first image

Chainlink oracle nodes can run Arbitrum L2 Validators and execute smart contracts off-chain in a highly scalable manner (270x more throughput in some cases)

The "team is dumping" narrative is a meme that needs to be put to rest

These tokens are being used to bootstrap and subsidize the growth of the most widely used oracle network

Reinvestment into a network's growth is a good thing, because projects that don't, stagnate and die
The token movements you see are used for a number of initiatives including:

- Subsidizing oracle networks to bootstrap a secure network of nodes
- Paying out community grants and blockchain integration grants
- Acquiring new technologies like DECO and funding security audits
- Hiring more devs to create software like OCR that lower gas costs by 90%
- Hiring more engineers to increase the rate integrations can occur
- Hiring more researchers to formalize the economics of staking
- Hiring geniuses like Ari Juels (RSA, IC3) and Ben Chan (BitGo, WBTC)

The new $LINK vault on @iearnfinance is a very welcome addition

Currently generates 70% APY
Zero impermanent loss risk
Lowers slippage of large LINK trades
Uses Chainlink oracles (Synthetix)
DeFi composability sandwich

A thread to learn more 👇
TL;DR

Deposit $LINK and/or $sLINK into the @CurveFinance LINK pool (curve.fi/link/deposit)

(sLINK is a token from @synthetix_io whose value tracks the price of LINK using Chainlink oracles)

You'll receive linkCRV as a tokenized claim on your deposit (like a receipt)
You then deposit those linkCRV tokens into the @iearnfinance crvLINK vault (yearn.finance/vaults) and receive yvlinkCRV tokens

Those are all the steps you need to take! The vault will do the rest

Wait a period of time and withdraw with more than you deposited

1/ "Off-Chain Aggregation" in the context of oracle networks is a bit confusing because it can refer to different things

- Collecting oracle observations
- Medianizing oracle observations
- Combining oracle signatures

Let's explore this
2/ Off-Chain Reporting (OCR) is where the collection of oracle responses is done off-chain

A single transaction is submitted on-chain containing every oracle's individual observation and signature

Median value is determined on-chain because the observations are already sorted
3/ The reason data isn't medianized off-chain before delivery in the OCR model is because the individual ECDSA signatures can't be used without the original pre-medianized data to compare against

We need the cryptographic security of signatures or observations could be falsified

1/ While I believe #Ethereum is and will continue to be the dominant settlement layer for smart contracts, ultimately there is a way to bet on all of them

Every single blockchain in existence needs a decentralized oracle network to achieve its true value proposition
2/ Communication protocols have a natural network effect where the protocol with the most connections is the only solution used at scale (HTTPS)

#Chainlink is the universal communication standard for any and all blockchains to connect to any and all off-chain data resources
3/ Chainlink is not only a data delivery network but provides everything blockchains natively cannot

Price Feeds
Proof of Reserve
Verifiable randomness
Cross-chain interactions
Insurable events and IoT
Keeper transaction automation
Trust-minimized off-chain computation
Much more
