From what I understand, the reason there is a 12s interval between each block is because of consensus voting, and the reason each block has a gas limit is because of sudden bursts of network and CPU/RAM usage.

What if we still do consensus voting every 12 seconds, but every consensus voting includes 3 blocks? So the block time is 4s but consensus voting only happens every 12s. A 4s separation between sudden bursts of high load seems more than enough.

I heard delayed execution is on the way. It basically spreads block processing across the entire 12s, so there will be no more sudden bursts. It should allow us to have very large blocks, but it is still years away. It seems much easier to just make consensus voting happen every 3 or 10 blocks instead of every block.

I'm pretty sure there is a good reason not to do this, otherwise it would have been implemented already, but I don't know what it is.

The Need

I've been looking for a DEX with an orderbook where I could list my RWA token for a fixed price fundraising, but couldn't find one. Here's my use case:

1. Initial Sale: I want to tokenize a real estate development project and sell tokens at a fixed price to raise construction funds
2. During Construction (1+ years): Token holders should be able to trade their tokens at prices they choose
3. Project Exit: After selling the property, I want to place a single large buy order at a fair price so all token holders can exit at the same rate
4. Capital Efficiency: All raised funds should be available for business needs (land purchase, materials, labor) without locking any portion in liquidity pools

While AMM-based DEXes like Uniswap have become the standard for DeFi, they aren't suitable for this type of RWA token because:

• AMM pools would cause price fluctuations, making it unfair for initial buyers and final exit
• They require locking significant capital in liquidity pools
• Price discovery mechanism doesn't match RWA trading patterns RWA trading often requires more precise price control and doesn't need the high-speed execution that AMMs provide. This post explores a simple approach to building an on-chain orderbook DEX specifically designed for RWA tokens.

The Problem

Traditional orderbook DEXes are often considered impractical on-chain due to:

1. High gas costs for order matching
2. Complex order matching logic
3. Front-running concerns
4. Speed limitations of on-chain execution

However, for RWA tokens, these limitations are less critical because:

• Trading velocity is lower
• Price precision is more important than execution speed
• Front-running is less profitable due to lower volatility
• Gas costs are more acceptable given higher transaction values

The Solution: Simple On-Chain Orderbook

We can build a simplified on-chain orderbook DEX with these key features:

Core Design

• One smart contract per token pair
• Fixed price steps to simplify matching
• Price-indexed mapping for orders
• Off-chain order matching calculation
• On-chain order execution
• Factory contract for easy deployment of new pairs

Data Structure

// Price -> [Orders at this price level]

mapping(uint256 => Order[]) public buyOrders;

mapping(uint256 => Order[]) public sellOrders;

struct Order {

address maker;

uint256 amount;

bool isBuyOrder;

}

Key Functions

1. Create Order
2. Takes price and amountValidates price stepTransfers tokens to contractStores order in mapping
3. Take Order
4. Takes existing order's price and indexTransfers tokens between partiesRemoves fulfilled order
5. Cancel Order
6. Only original maker can cancelReturns locked tokensRemoves order from mapping

Price Steps

• Each pair has a fixed minimum price step (e.g., 0.01)
• Prices must be multiples of this step
• Larger steps mean fewer possible price levels
• Reduces storage costs and simplifies matching

Frontend Integration

• JavaScript frontend calculates best matching orders
• Can easily scan available orders at each price level
• Simplified order matching due to price step structure
• Clear view of liquidity at each price level

Advantages

1. Simple and predictable gas costs
2. Easy to understand and audit
3. Precise price control for traders
4. No impermanent loss
5. Perfect for RWA tokens where speed isn't critical
6. Ideal for fixed-price token sales and fair exits
7. No capital locked in liquidity pools
8. Supports both fixed-price primary market and variable-price secondary market
9. Fair and equal treatment of token holders during exit events

Gas Optimization

1. Fixed price steps reduce storage complexity
2. Direct price indexing for quick lookups
3. Batch operations possible for efficiency
4. Simple matching logic reduces computation

Limitations

1. Higher gas costs than AMMs
2. Not suitable for high-frequency trading
3. Less capital efficient than AMMs
4. Requires more active market making

Future Improvements

1. Partial order filling
2. Better order prioritization
3. Multiple token pair support in single contract
4. Gas optimization for bulk operations
5. Integration with liquidity provider incentives

Conclusion

For RWA tokens, a simple on-chain orderbook can provide better price discovery and more precise trading than AMM-based solutions. While this approach wouldn't work well for high-frequency trading tokens, it's perfectly suited for the RWA market where trade frequency is lower and price precision is more important than execution speed.

The implementation is straightforward enough that it can be built, audited, and maintained by small teams, making it an attractive option for RWA token projects that need a custom trading solution.

What do you think about this approach? Would love to hear your thoughts and suggestions for improvements.

Aristotle's Revenge: Refers to the resurgence and validation of Aristotelian philosophy, particularly his views on nature and science, in light of modern scientific discoveries. The term suggests that many of Aristotle's fundamental ideas about reality, which were dismissed during the Scientific Revolution and Enlightenment, are being partially vindicated by contemporary physics and philosophy of science.

Let's analyze this example through the lens of "Aristotle's Revenge," breaking it down in three phases:

Phase 1: Initial Praise (The Original Truth)

• The project is presented and receives recognition
• Like Aristotle's original teachings, it is initially accepted and valued
• There's an intuitive understanding of its merit and potential
• The praise suggests the project aligns with fundamental truths or needs

Phase 2: Dismissal (The Modern Rejection)

• The project faces criticism and negativity
• Similar to how Aristotelian thought was dismissed during the Scientific Revolution
• "New" thinking or approaches are considered superior
• The original merits are forgotten or minimized
• There's a sense that the project is outdated or flawed compared to "better" alternatives

Phase 3: Vindication (The Revenge)

• The project proves its worth despite the criticism
• Like Aristotelian concepts being validated by modern discoveries
• The fundamental truth or value that was initially recognized re-emerges
• The dismissal is shown to have been shortsighted
• The project's success demonstrates that the original understanding was correct

Sounds familiar?

Alex Becker put out a video yesterday in which he posited that ETH will eventually surpass SOL because SOL has an “admin dashboard” — meaning that, if the powers that be want to terminate a project on SOL, then they can do so with the push of a button. However on ETH this is not as directly possible. Hence, (according to Alex) ETH will be the go-to crypto token for future developers, who are skittish about government intervention.

Is this claim warranted?

I’m unfamiliar with the debate so thanks for reading!

Hello, everyone!

I’ve been practicing with smart contracts in Solidity on Ethereum, and I came across a question: is it possible to encrypt data directly within a smart contract?

My goal was to use the blockchain itself to encrypt information using someone else's public key. However, I noticed that Ethereum doesn’t seem to have native support for this.

So, my question is: is there any way to encrypt data within Ethereum using another person's public key, whether with RSA, ECC, or some other approach? Has anything been developed to achieve this?

It seems like a natural fit. Autonomous agents need autonomy. Smart contracts could provide that. Could that be a breakout use care?

Edit: I'm asking about AI agents interacting with smart contracts, not being controlled by them.

I'm working on a project where I need to encrypt a message and send it over the blockchain so that only the intended recipient can decrypt it. The challenge is that I only have the recipient's Ethereum address, but encryption typically requires their public key.

Since Ethereum addresses are derived from the public key but don’t expose it directly, I’m looking for the best approach to encrypt data for a recipient without having their full public key beforehand.

How to tackel this any idea??

I came across a YouTube video explaining how to create a smart contract that utilizes a bot to generate money. I copied and pasted the provided code into Redux, then transferred funds to the smart contract. After compiling and deploying it, I moved money into a wallet. However, my funds now appear to be locked.

Just heard of it and it seems like a good way to move ETH, but googling it I found it had some issues about a year ago. Are there still valid concerns or do people use it now? Is there something similar that's better?

We have purchased a plot of land in La Plata, Argentina, and have obtained a building permit for a 4-story residential building.

We need to raise $100K for construction.

I'm exploring whether it's possible to tokenize the future building.

I want to keep the model very simple: issue an ERC20 token, 100K tokens total, sell the entire volume for 100K USDC.

Build the house, which will take approximately 1.5 years.

Sell the apartments, targeting around $300K in sales.

Distribute the net profit (after paying all fees and taxes) to token holders' wallets in USDC.

The project ends there.

In theory, this is RWA (Real World Asset). Could you suggest where I can learn about how to properly organize this? I've heard there are platforms that should help with the legal aspects, ideally with representation in Argentina.

Technically, issuing the token and creating scripts for its sale and profit distribution isn't difficult. What's unclear is how to avoid potential regulatory issues.

Let me know if you'd like me to help explore the RWA tokenization platforms and regulatory considerations for this type of real estate project.

I’d like to stake my ethereum in my trezor wallet but I’m afraid of slashing. How high is my risk for this. I don’t really see the point of staking at 3.48% p.a. If my risk is higher. Thanks

Anyone else in notice flashloan arbitrage profits on Eigenphi have completely tanked?
Like a year ago the monthly best would consistenly be 60k - 200k. This month the highest profit arb was only like 1.5k if that. Also there was a historically massive sandwich attack on 1/21, apparently worth ~800k. Not sure if this is related.
I can't really find any articles anywhere about this, MEV I guess is still sort of niche.

Has anyone else seen this?
What's going on with Flashloan Arb that profits are down so much?
Are sandwiches becoming so sophisticated that running plain Arb is getting crowded out?

Interested to hear opinions.

Hey everyone,

I (along with several other users) am dealing with an issue where we accidentally sent ETH to Polymarket, which only accepts USDC. Unfortunately, the ETH never showed up in our Polymarket accounts, and their support has been unresponsive, closing tickets without resolving the issue.

Issue:

• Funds are stuck, and Polymarket hasn’t returned them

What I’ve Tried:

• Contacted Polymarket support multiple times → they close tickets without resolution
• Checked Etherscan → the ETH was successfully sent, but Polymarket hasn’t credited or refunded it
• Tried asking in Polymarket’s Discord, but no real help so far

What I Need Help With:

1. Has anyone successfully recovered ETH sent to a platform that only accepts USDC?
2. Any way to recover ETH from a centralized platform’s wallet if they don’t respond?
3. Is there any on-chain method to retrieve the funds, or does it depend entirely on Polymarket returning them?
4. Any strategies to escalate this issue publicly to get Polymarket’s attention?

Would really appreciate any advice from those with experience in handling misplaced crypto deposits! Thanks in advance.

For example if you ctrl+f "blob" it will show zero results. Same for all new additions to the Ethereum protocol. How am I supposed to keep track of the current specification?

A laptop and 3 IoT devices are in my network:

1. The smaller devices collect sensor data which they exchange with each other.
2. The device closest to my laptop transmits all the data back to laptop.

How should I architect consensus into this setup? Do I really need wallets? and gas limits?

Hey everyone, I'm a dev with a long background in eth. I'm working on a new project now, and PDAs are very powerful. I'd like to include them, but ethereum has never offered anything like this.

Is there any discussion about PDAs? Anything on the roadmap? PDAs are the kind of platform innovation that makes development easier, and adoption more scaleable and user-friendly.

At this point, after working with erc standards forever, I am loving this PDA structure. I have to think I'm not the only one, and I don't see much interest around platform innovations for ethereum. But I would love to see an EIP for this.

Edit: Quick PDA summary if you're not familiar:

• PDAs are created by passing a program ID and an array of seeds through a hash function.
• PDAs look like public keys, but they don't have private keys.
• The seeds are an array of strings that can include things like the signer ID or escrow account.
• The "bump" seed is used to ensure that the PDA is not on the elliptic curve, which means it doesn't have a corresponding private key.

Why I like this

• No private keys, as mentioned
• can be used to create hashmaps and other structures on-chain, helping to structure data in a way that is easy to access and modify, especially programmatically. So they can be used to create accounts with flow control that are only accessible by a specific program.

I've been using Binance for a while, but comparing fees, the problem is that sending to my ledger once the transaction is over, is somewhat expensive (0.0012 ETH flat fee). On the bright side, for me sending USDT (TRC20) to Binance is free because I have enough TRX stacked to have free transactions.

So I wondered if there are better alternatives to swapping cryptos like USDT to ETH to send them to my ledger.

Generally, I like to swap around 200 USDT per month, but it's a ruin (including TRX fees with changelly), the total exchange cost, goes almost the same as Binance which happens to be expensive overall).

The thing is that it doesn't seem a good option overall for small transactions. But still, I'm trying to see which is the most convenient option to operate with ETH comfortably.
