Hey, so Messari recently put out a report where they claim that an optimistic rollup can run at a max tps of 5.2k, and that's only if rollup batches occupy the entire ETH L1 block (here's the tweet about it) (see the second row "ETH + Optimistic Rollups"). So this got me thinking, does this mean that if activity of a single optimistic rollup takes off for like a web3 game or DEX and it does run at 5k tps, then no other rollups or L1 transactions would theoretically occur on ETH? Taken to its extreme, this would mean that only one high-throughput L2 could settle on ETH, or maybe only a handful of L2s running at high tps (5 rollups running at 1000 tps?), and this can't be correct, right? Otherwise, why are all these groups building optimistic rollups. I know I must be missing something, or I'm hoping that the Messari report is incorrect, but please help me out here. Thanks in advance!

If it's true that stocks are dropping today because of fears that China's economy is becoming deflationary, then why is ETH becoming deflationary cheered as a good thing?

Apologies if this is the wrong place, I've looked for where to ask but don't see a subreddit of their own.

I frequently use Orbiter Finance to bridge between networks/layers, and it's honestly fantastic. I now wanted to implement it into a program, but am not sure how.

Do I just create a transaction from my MATIC network wallet, send it to the same address that it sends to when I use the website itself, and it will send back out the ETH to my ETH wallet on the same address? It seems like that's what it does, but am I missing some aspect where if I send in funds it would not return them?

Any help would be much appreciated.

Why do people do this? Layer-2’s are actually centralized — they’re mostly single sequencer EVM chains with no fraud proofs. Yes Ethereum is relatively decentralized, but between Solana and L2s, it’s not even close. This is especially true when layer-2s aren’t even scaling ethereum — they’re just basically separate blockchains that want to use eth for security in the future.

LaDAO del Xocolatl is adopting the new open cross-chain token standard for their Mexican Peso stablecoin $XOC. Their adoption of this standard means that LaDAO is in control of which bridges are supported and how many tokens each of them can mint, so risk can be minimized.

In emerging economies such as this Latin American country there’s a big demand for tokens to be available on many chains, particularly the cheaper ones to transact on. By being an xERC20, the liquidity costs of supporting multiple bridges and the slippage associated with cross-chain swaps are both eliminated.

With non-USD stablecoins gaining traction, how do you see the landscape of cross-chain stablecoins evolving?

I am not looking to be judged or told that I did something wrong, but yesterday I sent some USDP (Paxos Dollar) to my ETH wallet at Kraken. Immediately I realized they don't support USDP, and of course it never showed up in my account.

I can see the USDP on Etherscan. I put in a ticket at Kraken and they quickly sent me back a response that there is nothing they could do and they marked the case as "resolved." Really?

This isn't life-changing money, but it is enough for me to be mad at myself for sending the crypto to Kraken without remembering that they don't support it.

Is there anything I (or they) can do? Is that money just gone forever?

DEX223

We are building a decentralized exchange for ERC-20 and ERC-223 tokens. If you ever wanted to tell an exchange development team what you want from their exchange - it's your chance. We are accepting feature requests and we are open for any ideas.

Current exchange structure

The exchange will be based on smart-contracts and deployed on L1 and L2 chains.

It is planned to implement lending/borrowing of assets which allows for flexible margin trading. The implementation of a liquidation engine is not possible with smart-contracts so this part will be delegated to lenders and a system of incentivization. Liquidation will be a function of time and "expected balance".

ERC-223 token support will allow trading without approvals and increase gas efficiency approximately by 15%.

Transparent auto-listing. Exchange listings are the most difficult part of any project development. Even though the existing exchanges such as Uniswap are decentralized to some degree, listing on the UI is still a cumbersome process. We are planning to automate the listing process and make it as transparent as possible by introducing a "listing contract". Every token creator will be allowed to list the token by simply depositing a listing fee to the autolisting-contract and the token will appear at the UI in few minutes. Tokens will be divided into categories and the higher the listing fee the more visibility in the UI a token can get.

No KYC, no restrictions.

Hi!

I'm learning solidity, and had a huge struggle for random numbers (with Chainlink VRF).

Maybe it's just me but I don't understand why the oracles need to be set by us necessarily.

Why didn't chainlink provide their own?

The only reason coming to my mind is that there are a lot of networks so it wouldn't be scalable for them.

But why doesn't the community create shareable VRF Oracles?

So for learning purposes I made my own implementation of an abstraction which doesn't require for the end-user to setup an oracle himself.

It works like this:

• I created a subscription on chainlink

• I deployed a contract implementing Chainlink VRF contracts

• I added to it a system to fund the subscription for a given contract to consume

Result for the end-user is:

• Import my candy functions to retrieve the instance of my deployed "shared oracle"

• Deploy his own contract with the instance of my candy attached (via constructor)

• Fund the shared oracle when necessary via a candy function

Steps skipped:

• Read chainlink documentation

• Create a subscription

• Fund the subscription manually or writing a script

• Manage linkToken Address, vrfCoordinator address, keyHash, subscriptionID…

You just imported a library that allows you to populate secured random numbers.

Check the code:

I suppose that I've missed something, but I don't know what...

Can anybody enlighten me?

Thank you

EDIT: I think I realize now that it's not like with JS and candy libraries everywhere. In blockchain, if your SDK or library is not audited, no one is going to use it anyway

Security first!

I am looking to provide liquidity to the ETH/USDC pool on Arbitrum. Currently, I have ETH and USDC.e in my Arbitrum wallet. The USDC.e if the result of bridging ETH from Ethereum mainnet to Arbitrum.

If I provide liquidity of ETH/USDC.e, will it be included in the ETH/USDC pool (the biggest pool on UniSwap)? I believe that when contributing WETH/USDC, the WETH is considered equivalent to ETH, and therefore included in the ETH/USDC pool. I am wondering whether the same applies for USDC and USDC.e. If not, I would first need to swap USDC.e for USDC before providing liquidity.

Does anybody know if there is a way to track transactions between wallets for a token?

For example, I'm trying to find out if one whale holds multiple wallets, so if there are transactions sent between a bunch, that might give an indication one whale owns them all?

Any idea? Any online tools out there? Thanks.

Both OP and Arbitrum have been incredibly succesfull, both did airdrops.

ZkSync has had more users than any L2 and L1 in a day, 90% being airdrop farmers. What do you think is the future of L2s and Airdrops.

I read on Ethereum.org that L2 is the solution to solve the scalability of L1 when the network is congested, since it can only process 15 transactions per second.

With Bitcoin lighting L2 it makes more sense to me since the Bitcoin community has a very conservative view on tweaking away from the whitepaper.

But for Ethereum why don't they improve L1 directly and keep L2 for other things like tokens or rollups, for example simply to increase the frequency of epochs accordingly with the amount of new validators coming in would result in making the transactions of L1 faster and cheaper without compromising anything and rewarding validators slightly more, there are way more than enough validators active now to process the extra workload, seems like we're heading to a million active validators pretty soon, right now a validator will propose a block on average every 100 days.

What is the reason to scale through L2 rather than tweaking L1 ?

I finally got the green flag from my parents (I'm 16) so that I can buy myself a PC. I've been perfecting this list for a while now, but the time has finally come.

Is there anything I could improve? (without making the build more expensive, my budget is pretty limited) Any thoughts about it?

Originally, the internet was developed as an open and decentralized network for sharing information and facilitating communication. Over time, certain services and platforms gained dominant positions, leading to centralization of power and influence. Large corporations emerged, offering popular services and platforms that became an integral part of people's online experiences. Now we pay ISP's for access and they still control what we can and cant do. We shouldn't forget what was taken from us. The Ethereum blockchain is web3, and its a revolution to bring decentralization back to the internet.
