Pyth is designed as a decentralized protocol to avoid single points of failure. An obvious way to build an oracle is to run a server somewhere that collects data, aggregates it, and sends it to the blockchain. The problem with this approach is that the server is a centralized single point of failure. If that server goes down, the oracle does too. Also, the owner of the server could manipulate the results. That tradeoff is unacceptable for oracle users who demand security and reliability.

As someone who’s been in the crypto industry since 2013, one of the simplest yet most challenging questions I’ve faced is how to think about noncustodial trading interfaces. Do operators or developers of these NTIs have any regulatory obligations? Ideally not. I’m thrilled to finally have an opportunity to voice my opinion on the question in an effort to make a real change and provide a long-awaited answer. Today, I’ve submitted written comments to @SECGov’s crypto task force in an effort to make clear that NTIs—and folks developing or operating them—have no obligations under the securities laws to register as a broker or an exchange. NTIs serve simply as informational tools and technology layers that make communicating with blockchain systems easier. @HesterPeirce looking forward to hearing your thoughts! sec.gov/files/ctf-written-in…

honestly pretty cool implementation from @KaminoFinance even better than the mechanism, is the marketing on this product. its absolutely brilliant, rebranding limit orders as zero slippage is verifiably genius. big props to the kamino growth/marketing team limit orders by design are zero slippage in fact their product does have slippage, slippage can be both positive and negative, what kamino has done is eliminate negative slippage if i understand "surplus" in their docs correctly, that is slippage, but its just beneficial to the user who place the limit order what i do find strange when reading through their docs is that they turn market orders into limit orders that default +/-.1% off mark price. sure, this gets them to their "zero slippage" because its a its really just a limit order, but this means just means a market order may not fill immediately if solvers cannot find enough liquidity at that price i think that delineation is important to understand as a trader leveraging this mechanism your orders are never guaranteed to get filled when you place a limit order. you can have full, partial, or no fill at all. at the end of the day, intents systems are very similar to order books overall very cool mech from the kamino team and excited to see how it evolves over time!

The election is a referendum on the American ruling class. The ruling class consists of both Democrats and Republicans. Their interests are the policies that both parties support. Every administration supports foreign wars. Every administration supports key corporate interests, including the pharmaceutical industry and the banks. There’s very little difference between Bush and Obama: they both started a bunch of wars, they both expanded free trade, they both passed healthcare legislation without solving the drug cost problem, etc. The policies of our ruling class have hurt the people of this country. The people don’t want to fight wars in the Middle East – these have nothing to do with our defense, and they’ve bankrupted the country. Free trade has eliminated industry and people’s livelihoods. The 2008 crisis response further drove wealth inequality. We have the world’s largest healthcare spending and yet worse life expectancy than countries that spend half as much. We’ve lost the chance at building a peaceful world post Soviet Union and instead are at the brink of nuclear war. We’ve gone from being a rich productive country to one whose key export is financial instruments – this is a pending disaster that will impoverish us (regardless of administration) over the next decade as the world dedollarizes. The vast majority of the American people see that the ruling class doesn’t support their interests, and they’re angry. They’ve been angry since 2008, and we’ve seen this anger manifest in different ways: Occupy Wall Street, Bernie Sanders, and of course, Donald Trump. These movements are nominally left vs. right, but this is not the distinction that matters. They’re populist movements with the same underlying cause. Instead of responding to popular anger by actually helping the people, the ruling class has ruthlessly suppressed these challenges to its power. They rigged the Democratic primary in 2016. They created fake Russian interference theories to impeach Donald Trump, then did it again to suppress the legitimate evidence of corruption against Trump’s opponent in 2020. There are no bounds to their corruption and falsehood: the ruling class will do whatever it takes to hold on to power. In their quest for power, the ruling class has destroyed the legitimacy of our society’s institutions. Government agencies and the media are no longer trusted because they have consistently lied to the public. They have politicized law enforcement and used it as a weapon against their enemies, destroying rule of law. (Hillary is still claiming the 2016 election was stolen – where’s her court case?) They’ve created a vast censorship complex of government agencies and NGOs for combating “misinformation” on the internet, which is a direct attack on freedom of speech. This loss of legitimacy is extremely dangerous, and demonstrates the extent to which the ruling class will go to hold on to power. Ironically, as these attacks have escalated, they have actually helped @realDonaldTrump . In their desperation to stop him, the ruling class has escalated to increasingly obvious lies and corruption. The flagrant lies are waking people up – the gap between the lie and reality is simply too large to be ignored. If you listen to the media describe Trump, then listen to Trump himself, you instantly realize that the media has lied to you. The lie is so flagrant that it completely destroys the media’s credibility – you realize they simply do not care about the truth, and never have. It’s like seeing the matrix – it snaps you to a new interpretation of reality, where you see everything in a new light. It’s Wittgenstein’s ruler (“When you use a ruler to measure the table, you are also using the table to measure the ruler”) and you realize the ruler has been wrong the whole time. (Tangentially, the previous paragraph explains many of the so-called “mysteries” of the election. You periodically see the media wonder “how can all these people support a racist convicted felon who’s literally Hitler?” Well, there’s your answer – every time the media attacks Trump, they’re actually attacking themselves.) By surviving, Trump has attracted a counter-elite. All the people he’s touring with – @TulsiGabbard , @RobertKennedyJr , @JDVance , @VivekGRamaswamy , @elonmusk – are the counter-elite. It’s an assorted cast of characters, but the common theme amongst them is that they stand against one or more interests of the ruling class. Tulsi is anti-war, Elon is pro-free-speech, etc. This counter-elite is the seed of a new ruling class. Thus, the election is ultimately a choice between ruling classes. Do you want to stick with Hillary and Cheney? Or do you want to try something new? This is a freak event – few people have Trump’s survival skills – and you’ll never get another opportunity in your lifetime. Choose carefully.

Pyth just introduced a new staking mechanic to secure their price feeds and it looks pretty neat. I've been calling for some kind of economic stake tied to the integrity of data in the oracle supply chains for a while now, cool to finally see a project implement it. I like how the slashing process is carried out based on evidence with a report produced by the pythian council. That's an excellent purpose for that council on behalf of the protocol. What's left to be desired imo is the ability dispute the council's decision and escalate matters to a higher authority (e.g., token holders or a larger governance body)

The challenge for building OIS on Solana is to make it crankless. Every user's staking account state becomes stale over time. How do you keep the account states fresh without submitting a transaction on every single epoch? The staking program tracks an event log for each pool and automatically fast-forwards the account state whenever the user interacts with it. The log is a circular buffer to keep the account size bounded. It simplifies the ongoing operation.

Couldn’t agree more. The series of events that led to pythnet were: 1. Launch on the fastest L1 for defi: Solana 2. Solana becomes massively popular because many other builders came to the same conclusion as Pyth builders did and launched there 3. Pyth becomes too expensive to push to Solana mainnet, Pyth migrates to pythnet 4. Pythnet gets modified from mainnet to optimise for performance and depth of symbols 5. Pythnet stands on the shoulders of giants by getting backwards compatibility with wormhole and easy deployment 6. Pythnet continues to get more custom optimisations for the specific needs of constantly reducing latency and increasing capacity to service all blockchains. A utility like Pyth that services 400+ applications on 75+ blockchains warrants its own compute environment. Most apps don’t need this and would better benefit from a shared runtime. Btw @pythianism is a great name. You might be onto something ;)
Pyth is a great example of this. Pyth is awesome, creates a ton of value for solana dapps that far exceeds the value of the transaction fees that occur on the pyth side chain. Same with the Code wallet. It would still be better if mainnet was good enough that it was a no brainer for pyth to use mainnet directly instead of running its own chain.
