    Ethereum Berlin Upgrade Announcement

    Posted: 08 Mar 2021 09:45 AM PST

    Bit by bit over the past two months, I became a proud owner of 1 ETH!���� I did my first purchase for $100 when it was half of the current price and my latest purchase was for $500 right before the dip two weeks ago �� It’s only thanks to Reddit that I didn’t panic sell everything already, thank you!❤️

    Making the ecosystem more light-client friendly

    Posted: 08 Mar 2021 03:57 PM PST

    One of the challenges of the current Ethereum ecosystem is that while the protocol is theoretically light client friendly, and light clients even exist and can be used today, they're not nearly as commonplace as was originally envisioned. Particularly, all of the following environments could have been secured by light clients, but are instead typically secured by APIs connected to centralized services:

    1. Mobile phone clients/wallets, even those where the key management is trustless (Status, Argent, Loopring, etc etc)
    2. In-browser wallets (Metamask et al)
    3. Other blockchains

    There are two main problems:

    1. The Ethereum light client verification protocol is not light enough.
    2. There's not enough incentive to serve light clients, leading to weakened performance.

    We can think of each of these two problems as being tied to a corresponding one of the two key parts of a light client protocol. The first part is to download and authenticate the header chain, giving you Merkle roots to transactions and history and state; this is the part that is stymied by the Ethereum light verification protocol's heaviness. The second part is, given the Merkle roots, to get Merkle branches for any data you want to learn so that you can authenticate the data.

    Light client verification of headers

    (1) is a big deal. For a light client to stay synced with the eth-PoW network today, they need to sync the eth-PoW header chain, which is about 600 bytes per 13 seconds: trivial for a phone or browser app, but already getting expensive for the light-client-inside-a-blockchain use case. And in all three cases, it precludes the user-experience gain of instant syncing after a long time offline. Even worse, the PoW algorithm (ethash) takes a long time to verify. Despite being explicitly designed for light client friendliness with its "cache" mechanism, cache-based verification still takes a significant amount of time.

    The beacon chain has some upgrades in store, coming in the first hard fork, that allow light clients to stay synced with the beacon chain much more efficiently: a mere ~10 kB per day should suffice for basic connectivity. Verification will be significantly more computationally efficient than ethash.

    Note that even before the merge, a light client of the beacon chain can double as a light client of the eth-PoW chain: the beacon chain contains a hash of an eth-PoW block about 10 hours old, and so a client could choose to use the beacon chain to sync up to that point and then download eth-PoW headers from there. This would not be nearly as efficient as pure beacon chain verification after the merge, but it would still be a considerable gain.

    Merkle branches

    The problem with Merkle branches is simple. There are a lot of potential light clients, and each light client wants to learn a lot of information about the history and state, and it's expensive to send all that information and generate Merkle proofs for it. The problem is worse because there's no incentive to help send information, so relatively few nodes are doing it.

    There are two main kinds of solutions to this problem:

    1. Create a channel-payment protocol where nodes can get paid for supplying proofs.
    2. Reorganize the p2p network to make providing proofs simpler and cheaper; see Piper Merriam's work on this.

    But either path will take some time to get right, and there's a lot of work to be done (realistically there's a good chance we'll need to do both).

    A short term path

    But we should not despair from the complexity of a fully functional light client network. Even if all we can do is have a trustless header chain verifier, and we can't make a reliable and decentralized protocol to fetch Merkle branches, this by itself can greatly increase the security guarantees of mobile phone and in-browser clients.

    This is because instead of asking a server to provide responses to queries and trusting those responses, a wallet can now maintain the header chain locally, ask the server to provide responses along with Merkle proofs proving that the responses are correct, and verify the Merkle proofs. This is an intermediate mode that would be nice to move the Ethereum ecosystem over to soon. In the longer run, we can work harder on making a more fully decentralized light client ecosystem.

    Pow vs PoS and why 32 eth to become validator?

    Posted: 08 Mar 2021 05:12 PM PST

    PoS vs PoW and why 32 ethereum to be a validator?

    So im very new at mining but isn't this more about making rich ethereum users way more richer? as many others out there is very hard to make 32 eth at this price? While mining is way more cheaper and its working fine for everyone? Please explain this to me! Thanks

    Best way to learn about decentralized apps, without getting overwhelmed

    Posted: 07 Mar 2021 11:43 PM PST

    I am interested in decentralized applications (much more than currency use case). It seems like Etherum is the platform for that. However even as some with a tech background (10 years of coding), everything is extremely confusing to me. I will ask some questions and hopefully you guys have some guidance, thank you.

    1.) Is there any overall video or high level guide available on the state of the Etherunm user space.

    2.) With NFTS I see things like based on ERCXXX standard. What does this mean, are the different standards compatible.

    3.) When a company creates a coin on top of etherum. What does that mean, are they always easily transferable to other ETH based coins?

    4.) Is it possible to run arbitrary decentralized APIs on etherum. For example, say I wrote a web API in NodeJS. Could I somehow host it on the ethereum network, and route user requests against it.

    Stake ETH somewhere besides an exchange?

    Posted: 08 Mar 2021 05:32 PM PST

    Exchanges already have too much power over the market. Why stake with the big money and give them more dominance? Does anyone know where to stake ETH in some private pools? 🤔

    Or is this just not an option until EIP 1559 fully rolls out?

    Ethereum Exchange

    Posted: 08 Mar 2021 12:00 PM PST

    So you've gone head to head with bots, scalpers, and kijiji deals gone wrong, but you have prevailed, you've built a mining rig and it's awesome!

    Now, what's the next twist on this crazy ride?

    Well of course we have many options, some being:

    -Hold on to your loot!

    -Find an online business that offers goods for crypto

    -Buy and sell your coin on an exchange

    These are all fantastic options and widely used by many. What was that you asked? Oh you want to trade your digital dollar for some fiat? Of course you do, you need to pay off that rig right? Right.

    Well this is the question that has me wondering as well. How do you trade your ETH for fiat dollars? Can it be done anonymously? Who offers this service? Are there preferred "vendors" or options? How is this being done? The bottom line is, how do you cash your ETH in for fiat dollars with emphasis on anonymity?

    Maybe it's just me but I find this to be a slightly overlooked topic when it comes to searching for the right answers on the web. Which brings me to this wonderful community with never ending buckets of knowledge. Will you folks point me in the right direction? Maybe a few tips and tricks?

    I thank you all in advance for every little bit of info that you're willing to part with. I love this community!

    Need help - Restoring Ethereum from 2017 smart contract

    Posted: 08 Mar 2021 01:34 PM PST

    Hi,

    I used the official ethereum wallet from 2017. I did send 6.8 ether back then from my wallet to my smart contract. But now I can't open the ethereum wallet, but I have the keystore file. I also have the smart contract address and the ethereum wallet address. I also have the password for the ethereum wallet from 2017.

    Can I somehow restore my account and send the ethereum from the smart contract to another ethereum wallet?

    I would really mean I lot to me, because I am in a bad financial situation and need the money. I would also give you a reward, when everything is working out.

    Ethereum Developer Shares How EIP-1559 and PoS Accrue Value to ETH

    Posted: 08 Mar 2021 06:36 PM PST

    Old Macbook has 3 ETH in MetaMask - forgot password, any way to recover?

    Posted: 08 Mar 2021 06:30 PM PST

    First thing you guys will think is I stole some random laptop but I am happy to prove I own the address that sent the funds into the wallet in the first place.

    I know this is a longshot but is there any way to extract the privkey from the hard drive? At this point, I don't care if I have to tear apart the 2013 Macbook Pro...

    Any help would be much appreciated, you guys aren't Bitcoiners so please save the yOu'Re ScReWeD posts, this happens to the best of us. Thanks!
