Forgot you need to bridge...its been a while since i did a crypto transaction. Any way to recover them? Transaction via metamask says confirmed, but not sure if it's even a really wallet address on fantom.

Can you believe it’s already been 6 months since the Dencun upgrade and the launch of blobs?

The Dencun upgrade brought us the much-anticipated blobs via EIP-4844, which have improved the Layer 2 users’ experience by making transactions cheaper and more efficient.

Let’s take a moment to review the progress blobs have made over the past half-year:

• 2.3 million total blobs since the Dencun upgrade
• 596,000 blocks containing blobs
• 1.1 million blob transactions

These numbers only scratch the surface of the significant impact blobs have had on the Ethereum ecosystem, enhancing both efficiency and usability.

The momentum around blobs is growing, with more and more submitters joining in. We now have a robust ecosystem that includes Base, Optimism, Arbitrum, Taiko, Scroll, Blast, Linea, Starknet, Zora, Zircuit, Kroma, and many more.

This growing network of L2s is making Ethereum more efficient, affordable, and driving innovation across all layers and dApps.

EIP-4844 also introduced a smart mechanism that adjusts the blob base fee according to supply and demand. Recently, we’ve seen the reaching the current target - 3 blobs per block. This dynamic fee model is designed to keep blob processing efficient and optimize block space.

Before EIP-4844, there was a lot of uncertainty around pricing. But now, it’s clear that blobs have surpassed expectations. Comparing the cost of blobs to calldata on Rob's dashboard shows just how much cheaper blobs are.

A huge thank you to everyone who contributed to making this upgrade a reality on the Ethereum mainnet!

I’m exploring ways to reduce the finality time for optimistic rollups on Ethereum. My idea builds upon the `Check-In model`, which has some known cost-related issues when requiring every validator to check in. I propose the following revised approach and would appreciate feedback on its feasibility, potential problems, and any overlooked attack vectors.

1. Validator Selection: In each epoch, a set of validators is chosen to be responsible for submitting check-ins for rollup batches.
2. Quorum-Based Validation: If a quorum of the chosen validators submits check-ins without fraud proof, the rollup batch is marked as valid. If any one validator within the quorum submits a fraud proof, the system will handle the fraud proof accordingly.
3. Concurrent Processing in Execution Client: To efficiently validate rollup batches, I propose introducing a separate queue and concurrent thread handling mechanism in the execution client. This would allow for the validation of multiple rollup batches concurrently (up to X threads for X batches), minimizing the impact on the main execution process.

Questions

• Would this model be effective in reducing the finality time for rollups?
• What are the potential issues, such as cost, security, or operational concerns?
• Could this approach introduce new attack vectors, such as validators withholding check-ins or spamming fraud proofs to disrupt the network?

Any insights or suggestions for improvement would be greatly appreciated.

Hi, I'm new to crypto and I think I made a big mistake.

I had polygon USDT sitting in my wallet and I thought I should stake it. So I staked it as sideshift tokens (svXAI/XAI) on the ETH network, and it automatically subtracted the gas fees from the amount that I deposited. However now I need to unstake them, and it seems like I need some ETH for the gas fees.

I don't even know how much gas it would need, but I think it would be around $2-$3. I don't have any leftover crypto I could swap for ETH except like 20 cents of polygon that I used to pay gas on the polygon network.

I really cannot buy ETH to pay these small fees. I talked with sideshift support and they said they cannot subtract the amount from my tokens. Do I have any options?
Please I'm really at a loss here.

Hi, I use SBI VC Trade exchange in Japan.

The default setting is to receive rewards for Ether staking.

I can turn this off, but the exchange won't confirm whether this actually stops my Ether from being staked or whether they carry on regardless.

I have tried contacted support countless times but they cannot/will not answer straight.

What is the usual practice when it comes to opting in and out of Ether staking on exchanges?

How high is the risk of slashing. SBI is a major online brokerage platform in Japan...

Hey everyone

I'm currently trying to decide which stablecoin to use, but I'm concerned about censorship and the possibility of my funds being frozen. I know that both USDT (Tether) and USDC (USD Coin) have had issues in this regard:

USDT: Tether has been known to freeze addresses when asked to by law enforcement or other authorities. This has happened multiple times in the past, which raises concerns about how safe it is to hold USDT if you're worried about potential censorship.

USDC: USD Coin is designed to be fully compliant with U.S. regulations, which means it also has the ability to freeze funds and block transactions if required by the government. Given that it's backed by regulated financial institutions, it seems more prone to responding to regulatory pressures.

Considering these factors, which stablecoin would you say is the safest option if I'm trying to minimize the risk of censorship or having my funds frozen? Are there other stablecoins that might be better in this regard?

I want to stake ETH but only to receive the new reward ETH once per month.

So, why would I want infrequent rewards?

That way, I won't have a zillion new cost basises every year for US tax purposes. Just 12 new rows in a spreadsheet.

Does any cex or pool provide this?

It took some doing, but I got Coinbase to admit that if they stop supporting Coinbase Wallet, everybody who has staked their Eth there loses it.

Trust Wallet seems to be the same way, and even MEW doesn't seem to provide any reassurance that I can unstake & access my Eth in the event MEW disappears forever.

Is there any safe way to stake? Run my own validator or something techy like that?

I've seen a million posts about people who send things to their exchange's deposit address that they shouldn't have, and they have to beg the exchange to recover the money. or they try to withdraw money and end up receiving it on the wrong network.

a new address format would take a person's address, a chain ID, and optionally a token contract, and just mash them all together. for example:

vitalik's ETH address

0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045

the chain ID of Arbitrum One

0xa4b1

the contract address of the USDC token

0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48

combine these together

0xd8dA6BF26964aF9D7eEd9e03E53415D37aA960450xa4b10xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48
    

what this would do is, when you paste it into your wallet, it will instruct your wallet to only send USDC on Arbitrum One to vitalik. or to send ETH, just don't add a contract address. your wallet would have to separate the pieces and perform a regular transaction using the traditional address format, so the network itself doesn't really need to know that you used a longer address. it's not that much different from how bitcoin mainnet QR codes may add instructions such as a requested amount.

Made this stupid mistake of transferring stETH without unstaking it before sending it to my ETH address on Binance.

it's my own wallet but stETH isn't listed on Binance, so the funds aren't showing on the exchange. Has this happened to anyone before? Dyou have any informed idea on the chances of recovering the funds that were transferred?

Already submitted an appeal to binance, if they recover the funds they’ll charge a $200 fee for it

Hello Everyone.

I am relatively a new artist, trying to create more digital images. I like to upload a few avatars to reddit and also upload a few animated Gifs I created. Most places ask for a "Ethereum-compatible blockchain account" that needs to be connected with a digital wallet on the sites.

my questions are:

1: are there multiple Ethereum-compatible blockchain account or sites? in other words, is this just one wallet or different sources provide this?

2: if so, which one is the better one (Safe and secure one)?

Thank you, In advance for your help. I am new to blockchains, nfts, digital money and all that, so I appreciate your help

I currently have my Eth staked in Coinbase Wallet. What happens if Coinbase goes bankrupt like FTX? Is my Eth safe? Can I just import my wallet using MetaMask (or whatever) and carry on?

I've been looking into account abstraction features and account recovery sounds like something very important to improve the user experience.

But it come with counterpart, most of theses method introduce trust and centralization in the process.

So I tried to imagine a way to recover account in a fully decentralized way.

And I found something, and I would like to share it with the community to know if it could be a good Idea or not and if it's a good one, is it already existing ?

The idea is to create a recovery contract. The contract has the right to assign a sender into authorized signers in the smart account. We can imagine to plug it to the factory or something like that.

The idea is to use 2 parameters, a recovery deposit and a a time lock duration.

To recover an account you have to send the recovery deposit to the recovery contract and wait for the time lock duration.

During timelock, the signers of the smart account can decline the claim and the recovery attempt is cancelled. Then the recovery deposit is sent to the smart account.

If nothing happens after timelock, then the claimer become a smart account signer.

The 2 parameters can be set by the owner based on his risk tolerance and his balance. A 500eth account should have a higher recovery deposit and more timelock to avoid people trying to recover it.

Hypothetically, anyone can try to recover an account but due to the deposit needed, the risk to do it will Discourage people to try it. And in case it happens, it also reward the owner as a sort of "compensation".

I also imagined some counter to fraudulent attempt like frontrun, some people can try to listen mempool to find account recovery transactions and frontrun them cause they are sure that theses account are not protected cause owner has lost access to it.

The counter is to make the process in 2 transaction:

1. a proof of intention sent to the recovery contract witch is just a hash of the account to recover and the address of the claimer.

2. The claim. In the claim function the contract will hash the sender and the account address, and if there is a matching hash in the proof of intention list, then transaction is valid.

By this way the claimer can't be frontrunned and will get access to his account before frontrunners. We can also imagine to set a limit of 1 recovery attempt at the same time to avoid people to claim just after to try to stole funds.

What do you think of this system? It could be implemented as optionnal recovery method for people who don't want to trust people to recover their account.

Would you stake different coins and through different means?

Is there a coin that is safer to stake than others or a way to stake that is safer?

So you just pick the ones with the highest APY or how do you choose?

Think about it in terms of trying to create an annual return that is close to livable.

So, I’ve been diving into the world of decentralized finance lately, and one thing that keeps bugging me is how tough it is to swap BTC for ETH without having to rely on a centralized exchange. I mean, we all know the risks—custodial issues, potential hacks, and the fact that centralized exchanges are pretty much the opposite of what crypto was meant to be.

I’ve tried a few decentralized options, but they either feel too slow, have insane fees, or just seem too complicated for what should be a straightforward process. Maybe I’m missing something, but has anyone found a solution that’s truly decentralized and doesn’t make you want to pull your hair out from frustration?

I’m talking about something that actually delivers on speed, security, and ease of use—because, let’s be honest, it’s 2024, and we should have better options by now, right?

As title says, I’m looking for famous wallets in which the private key has been published publicly. I know they are sometime released as promotional deals, as a way to renounce ownership, etc

Any ideas?

Hey guys,

I am new to the crypto world and I am non stop learning and reading stuff, I would appreciate some clarifications regarding the creation and import of a DeFi wallet because I couldn't find anywhere clear answers.

First of all, does it matter which app someone is going to use to create his DeFi wallet? Does it make any difference (in security or any other) if I create my defi wallet via metamask or coinbase or exodus or some other app?

Secondly, no matter where I created my defi wallet, I can import it to another defi app, for example I can create it via coinbase and then import it to metamask, is there any impact to the wallet when you import it on different apps? (Is this info stored somewhere? Does it make it easier to compromise?)

Bonus question about railgun: I have read multitple posts about it, is it used only to hide your coins or is it a method to increase security on your wallet too? Is it better to keep the coins shielded or it doesn't matter?

In Etherscan/protocol-level, the block times differ by 12s. In reality, how accurate are these timestamps to the actual UNIX timestamp of, say, when the validator proposes the block?

I am running a Geth node and seeing block times that are between 10-14 though sometimes 8-16s. I can't tell if this is because my node's variance is high or the actual block time variance is high.

(Yes, I am aware that there is no "actual block time" but the variance is very high so hence the question).

Guilherme, who's been with the Cartesi Rollups on-chain team since 2021, shares his thoughts on the tricky topic of upgradability in blockchain. He compares the forced upgrades in web2 software with the trustless nature of web3, where smart contracts can't be changed once deployed. He talks about the balancing act between trust, complexity, and user experience, while noting that Cartesi Rollups is making strides towards full trustlessness with innovations like the Dave fraud proof system. Truly an insightful piece!

Like most of you I fucked around with alt coins and even a few shit coins. I don't track most of them anymore and worried I'm leaving money on the table. Obviously moving forward I'm more careful but I started with the idea this was all EASILY traceable and this wouldn't be an issue. No knock on it, I just didn't understand how deep the web went lol.

Hey all,

We are running a bounty program at Zama (currently in Season 6), inviting our dev community to create innovative projects using Fully Homomorphic Encryption with Zama's fhEVM.

This season, we're challenging the community to explore and implement how the specific capabilities of Zama's fhEVM can enhance and improve the functionality of the ERC-3643 security token standard for security tokens.

Read more here: https://github.com/zama-ai/bounty-program/issues/128

If you're interested in what people have been building during the previous season, you can read more about it here: https://www.zama.ai/post/zama-bounty-program-season-6

In my recent report, which celebrates 9 years of Ethereum, I not only revisit the main events that shaped it into what it is today and oversee what it may become tomorrow but also analyze 3 and a half years of ETH staking.

While it seems that our beloved chain has linear stake growth, which is partially true (see the upper chart), when we drill down a bit deeper — the reality seems to be different. Thus, to represent this fact two charts — absolute staked ETH and stake delta — are combined.

The chart below, which presents the delta of stake inflows and unstakes, shows the tendency of repetitive staking activation cycles. The biggest spikes of staked Ether are usually around the upgrades, each of which brought some highly anticipated feature: either burn, staking, withdrawals, or Proto-Danksharding (also known as blobs), showcasing strong community confidence and support for new Ethereum.

If you like this fragment, you can find this and more interesting observations in the report itself: https://everstake.one/crypto-reports/ethereum-is-9-blow-candles-and-celebrate-key-milestones

I have some ETH in a wallet that I on-ramped from a KYC exchange. I would like to move this to my cold storage without having it linked to my identity.

Anyone aware of a smart contract or dApp that anonymizes transactions? Should be pretty easy to implement as far as i can tell. Just send ETH to a wallet with a smart contract that gives you back the same amount of ETH. Having many people send the same amount of ETH to the smart contract should obscure it enough.

I've send a couple hundred bucks worth of eth from my bingx account to my new ledger account (first transaction lol) using their optimism network and 14 hours later i still don't have the funds in my ledger? The address is indeed correct.
