How To Mine Ethereum On Windows And Mac : All You Must Know.

Ethereum Classic

Ethereum Classic is an open, decentralized, and permissionless public blockchain, that aims to fulfill the original promise of Ethereum, as a platform where smart contracts are free from third-party interference. ETC prioritizes trust-minimization, network security, and integrity. All network upgrades are non-contentious with the aim to fix critical issues or to add value with newly proposed features; never to create new tokens, or to bail out flawed smart contracts and their interest groups.

I just installed Ethereum Wallet on my Mac, looking at getting some Ether but bit confused...

I know a lot about Bitcoin but little about how Ether wallets etc work. My address is 0x36D46A5d58C8Bf48115b222672AfdE645B37D5a0 and looks different to a BTC wallet address.
If I buy some Ether on like Kraken or something, how do I go about sending it to my Ether wallet. I saw I can make a 2nd account/wallet too? Can I hold BTC in one and Ether in another? Cheers for any help.

Using Ethereum Wallet on Mac. My hard drive is almost full and only 22% updated.

Is there a way to have a light version of the wallet without downloading the whole ledger? My hd is very small and it's been more than 15 hours since I started updating.

Da Hongfei AMA (Full AMA Post)

Hello everyone, I compiled all answers from Da Hongfei’s AMA on Flamingo into an overview document for anyone who missed the AMA itself but wants to read the information. Should be helpful for anyone who doesn’t want to scroll all the way back through the discord. I cleaned up his english slightly, but there are still many errors I chose not to correct for the sake of authenticity. Hope that’s appreciated. Enjoy!
First question: Hongfei, As an established public chain, what are the considerations behind Neo’s decision to incubate the Flamingo project?
I would say there are several considerations
First of all, many members of the team, the community and myself as well are all optimistic about the future of DeFi, we truly believe that it’s going to change the existing financial paradigm.
Neo, as a digital asset protocol, has a relatively mature smart contract system, a large asset base, and an active community across the world, which makes Neo a good platform for DeFi.
In the past, NF and NGD were not directly involved in incubating projects, but helped community projects in the form of funding and Tech. This time NGD participated in the incubation process because some basic modules are needed in DeFi development, and we have to compete against time. Neo3 will be launched around January next year, and we very much need to understand the requirements of the application layer in order to do a good job in the protocol layer.
We do discovered some areas to improve at layer 1 and we did such necessary changes
At the same time, I also hope that we can activate the global Neo community through this opportunity and explore our future directions together.
Let's move to the next question for Hongfei, how do you position Flamingo in Neo’s ecosystem and Flamingo’s significance in the whole industry?
Flamingo is the enabling module of Neo’s DeFi ecosystem, and we can see that Swaps are the most core module in the recent rise of DeFi. This is an important marketplace to connect all kinds of assets.
Through NGD’s incubation, we are quickly implementing our own Swap base on Neo smart contracts (rather than a simple imitation of Ethereum-based Swaps). Besides Swap, Flamingo will also provide: (1) collateralized synthetic stablecoin – FUSD, similar to Synthetix sUSD and MakerDAO DAI, (2) using FUSD to do 10x margin trade of AMM-based perpetual contract.
We hope that more developers can use basic modules of Flamingo to develop more applications. From a macro point of view, if Flamingo is proven to be successful, then we will bring some insights about originality to the public blockchain space, instead of the current situation where team are rushing to Ethereum to build liquidity pools cascaded by liquidity pools.
Thank you Hongfei, The third question: Why do you think Flamingo will stand out in the current DeFi craze?
I summarized the following highlights for Flamingo:
(1) high capital utilization:
for example, the LP Token (liquidity provider’s proof in Swap) can be used to mint FUSD, an FUSD can be used to trade 10x perpetual contracts. This is a great advantage of the Flamingo full-stack model, where the liquidity of each module can be reused to the maximum extent.
(2) fair launch and equal opportunities
Flamingo does not have any pre-sale, team reservation, or pre-mining, everyone participates on a leveled ground
(3) asset diversity:
During Mint Rush, in addition to the NEO pool which will have 50% of the FLM distribution, another 50% of FLM will be obtained by staking cross-chain assets. This includes WBTC, ETH, USDT, Uniswap V2 WBTC/ETH LP, ONT and a few other assets (will announced later). Moreover, most of the ERC20 assets can continue to generate yields on Ethereum, as well as farming on Neo.
(4) We will also launch DAO governance module as soon as possible to allow the community of FLM holders to steer the wheel for Flamingo.
Next question~ As a very important module of Flamingo, many community members are interested in Flamincome, but many are still confused about it. Can you explain to us how it actually works?
Flamincome is built on Ethereum, we can it "Ultimate Yield Booster". It is similar to yEarn but do cross-chain farming as enhancement. Let me give you an example to illustrate it better:
For example: Alice deposits USDT (imagine it as deposite money) into Flamincome and gets a fUSDT token (the certificate of deposit), which can then be staked and normalized into a new token called nUSDT which pegs to the original asset USDT (a loan against the certificate of deposit). The newly minted nUSDT can then be transferred to Neo blockchain to participate in farming in Flamingo. USDT and nUSDT are mining for you at the same time at two blockchains, which is the magic of Flamincome.
https://media.discordapp.net/attachments/748375438467793039/757608623911469207/LN05iqxTggRwuOVvYn0FYw.png?width=765&height=428
The specific process is shown in the figure above. It’s quite complex, which is why I said don't expect the user experience to be good. But money never sleeps. I think the more important thing is how to improve the utilization rate of capital.
This cross-chain "Ultimate Yield Booster" looks like a perfect fit for DeFi Scientists!
Next question:
Flamingo is defined as a project that allocates all incentives based on contribution. Would you explain to us about this?
This involves the highlight of radical equality I mentioned earlier. There are several types of actions that can be defined as contributions in Flamingo:
  1. Minting/staking assets, including native (NEO) and cross-chain assets (BTC, ETH... ).
  2. Providing liquidity into asset pools such as Swap's FLM/NEO pair.
  3. Minting FUSD stablecoin, by staking assets to Vault and use it as collateral to mint FUSD.
  4. Trading perpetual contracts and providing liquidity for Flamingo Perp.
  5. Using FLM to govern Flamingo via DAO.
The next question is quite frequently raised: The upsurge of DeFi is accompanied by a lot of chaotic situations, so the security of the smart contract is an issue of great concern. How is Flamingo guaranteed in terms of security?
First of all, to do yield farming, or liquidity mining, although it does not cost money, you have to stake your assets into the smart contract, so there is opportunities cost and safety concerns.
security of contracts and wallet is our first priority. All contracts are audited before going live, Neoline is also under significant tests. The audits of Flamingo and Flamincome are done by PeckShield and the audit reports will be released soon.
Matured farming strategies from yEarn are re-used to ensure safety
OK, here is another question also drawing lots of attention within the community. As a project incubated by NGD, Flamingo has a to become a project governed by DAO. So how will the Neo Foundation and NGD participate in the Flamingo?
In order to ensure the security and a better user experience, we decided to postpone the launch of Flamincome on Ethereum for 2 days.
So Flamincome and Flamingo Wrapper will launch together on the 23rd, followed by a two-day period for users to do cross-chain assets wrapping/minting. The Mint Rush will still start on the 25th, together with the launch of Vault. FLM will start to generate on 25th.
So 23rd is more like preparation, 25th is the starting date
23rd September UTC 13:00: Launch of Flamincome and Flamingo Wrapper
23rd September UTC 13:00: Launch of Flamingo Vault and "Mint Rush" starts, as well as distribution of FLM
During Mint Rush you only need to stake your assets for a total of 5 days and there is no impermanent loss.
Only by providing liquidity to Swap, you may bear IL
After all, the IL is not as terrible as many people think.To provide liquidity to a trading pair A/B, after a period of time, if the price of A has fallen by 50% relative to B. How much do you estimate the impermanent loss to be?
(that's question for you folks)
No one could answers Hongfei, they were muted~
haha . The answer is 5.72%. Which means you would only lost 5.72% by providing liquidity compared to holding A/B in your wallet.
that's not as bad as most people's intuition
The following are comments from Da after the AMA was complete:
Da on Gas: The market cap of GAS is too small, you can't use it to stake, otherwise will drive the price too high, and too expensive to do tx
Regarding NEP5 tokens, same situation, Market Cap too small to be used
All tokens Flamingo use have over 100M cap.
FLM distribution starts on 25th, but you need to wait 2-3 days before you can actually claim it
Currently you can use Ledger with Neon PC wallet, but unfortunately Ledger is not working with any Neo chrome extension wallet (ie. Neoline) yet
I agree we should push the integration between wallets and ledger
Wrapping is safe
Neoline chrome extension (PC) will work, and probably O3 desktop (PC/MAC)
I'm not sure O3+Ledger will be ready on 25th, need to check it out tomorrow
I don't have a number for tx fees, let's see when i launches
i don't comment on listing questions
it's out of my scope
On Neo 3.0 launch
Jan 2021 is more realistic. Xmas, new year... many core devs are in christian countries
NF/NGD will participate for three purposes:
(1) To get FLM and later provide liquidity for NEO and FLM pairs for the Swap to be launch on 30th
(2) To use the FLM to participate in governance. We aim to make Flamingo governed by DAO as soon as possible
(3) To use the FLM for the future operation and incentive NF/NGD will ensure non-NF/NGD participation takes up the majority of NEO pool
to mint cross-chain asset, you need Metamask and Neoline
i think it might be a good idea to build a browser which natively support all major blockchains
17.5% others will be announced soon
I not sure whether ledger can be used or not. The devs are not testing with ledger, only neoline
so don't have too much expectation pls
but maybe O3 team is working on it, let's see for the next couple of days

Ethereum on ARM. New Eth2.0 Raspberry Pi 4 image for joining the Medalla multi-client testnet. Step-by-step guide for installing and activating a validator (Prysm, Teku, Lighthouse and Nimbus clients included)

TL;DR: Flash your Raspberry Pi 4, plug in an ethernet cable, connect the SSD disk and power up the device to join the Eth2.0 medalla testnet.
The image takes care of all the necessary steps to join the Eth2.0 Medalla multi-client testnet [1], from setting up the environment and formatting the SSD disk to installing, managing and running the Eth1.0 and Eth2.0 clients.
You will only need to choose an Eth2.0 client, start the beacon chain service and activate / run the validator.
Note: this is an update for our previous Raspberry Pi 4 Eth2 image [2] so some of the instructions are directly taken from there.

MAIN FEATURES

SOFTWARE INCLUDED

INSTALLATION GUIDE AND USAGE

RECOMMENDED HARDWARE AND SETUP
STORAGE
You will need an SSD to run the Ethereum clients (without an SSD drive there’s absolutely no chance of syncing the Ethereum blockchain). There are 2 options:
Use an USB portable SSD disk such as the Samsung T5 Portable SSD.
Use an USB 3.0 External Hard Drive Case with a SSD Disk. In our case we used a Inateck 2.5 Hard Drive Enclosure FE2011. Make sure to buy a case with an UASP compliant chip, particularly, one of these: JMicron (JMS567 or JMS578) or ASMedia (ASM1153E).
In both cases, avoid getting low quality SSD disks as it is a key component of your node and it can drastically affect the performance (and sync times). Keep in mind that you need to plug the disk to an USB 3.0 port (in blue).
IMAGE DOWNLOAD AND INSTALLATION
1.- Download the image:
http://www.ethraspbian.com/downloads/ubuntu-20.04.1-preinstalled-server-arm64+raspi-eth2-medalla.img.zip
SHA256 149cb9b020d1c49fcf75c00449c74c6f38364df1700534b5e87f970080597d87
2.- Flash the image
Insert the microSD in your Desktop / Laptop and download the file.
Note: If you are not comfortable with command line or if you are running Windows, you can use Etcher [10]
Open a terminal and check your MicroSD device name running:
sudo fdisk -l
You should see a device named mmcblk0 or sdd. Unzip and flash the image:
unzip ubuntu-20.04.1-preinstalled-server-arm64+raspi-eth2-medalla.img.zip
sudo dd bs=1M if=ubuntu-20.04.1-preinstalled-server-arm64+raspi.img of=/dev/mmcblk0 conv=fdatasync status=progress
3.- Insert de MicroSD into the Raspberry Pi 4. Connect an Ethernet cable and attach the USB SSD disk (make sure you are using a blue port).
4.- Power on the device
The Ubuntu OS will boot up in less than one minute but you will need to wait approximately 7-8 minutes in order to allow the script to perform the necessary tasks to install the Medalla setup (it will reboot again)
5.- Log in
You can log in through SSH or using the console (if you have a monitor and keyboard attached)
User: ethereum Password: ethereum 
You will be prompted to change the password on first login, so you will need to log in twice.
6.- Forward 30303 port in your router (both UDP and TCP). If you don’t know how to do this, google “port forwarding” followed by your router model. You will need to open additional ports as well depending on the Eth2.0 client you’ve chosen.
7.- Getting console output
You can see what’s happening in the background by typing:
sudo tail -f /valog/syslog
8.- Grafana Dashboards
There are 5 Grafana dashboards available to monitor the Medalla node (see section “Grafana Dashboards” below).

The Medalla Eth2.0 multi-client testnet

Medalla is the official Eth2.0 multi-client testnet according to the latest official specification for Eth2.0, the v0.12.2 [11] release (which is aimed to be the final) [12].
In order to run a Medalla Eth 2.0 node you will need 3 components:
The image takes care of the Eth1.0 setup. So, once flashed (and after a first reboot), Geth (Eth1.0 client) starts to sync the Goerli testnet.
Follow these steps to enable your Eth2.0 Ethereum node:
CREATE THE VALIDATOR KEYS AND MAKE THE DEPOSIT
We need to get 32 Goerli ETH (fake ETH) ir order to make the deposit in the Eth2.0 contract and run the validator. The easiest way of getting ETH is by joining Prysm Discord's channel.
Open Metamask [14], select the Goerli Network (top of the window) and copy your ETH Address. Go to:
https://discord.com/invite/YMVYzv6
And open the “request-goerli-eth” channel (on the left)
Type:
!send $YOUR_ETH_ADDRESS (replace it with the one copied on Metamask)
You will receive enough ETH to run 1 validator.
Now it is time to create your validator keys and the deposit information. For your convenience we’ve packaged the official Eth2 launchpad tool [4]. Go to the EF Eth2.0 launchpad site:
https://medalla.launchpad.ethereum.org/
And click “Get started”
Read and accept all warnings. In the next screen, select 1 validator and go to your Raspberry Pi console. Under the ethereum account run:
cd && deposit --num_validators 1 --chain medalla
Choose your mnemonic language and type a password for keeping your keys safe. Write down your mnemonic password, press any key and type it again as requested.
Now you have 2 Json files under the validator_keys directory. A deposit data file for sending the 32 ETH along with your validator public key to the Eth1 chain (goerli testnet) and a keystore file with your validator keys.
Back to the Launchpad website, check "I am keeping my keys safe and have written down my mnemonic phrase" and click "Continue".
It is time to send the 32 ETH deposit to the Eth1 chain. You need the deposit file (located in your Raspberry Pi). You can, either copy and paste the file content and save it as a new file in your desktop or copy the file from the Raspberry to your desktop through SSH.
1.- Copy and paste: Connected through SSH to your Raspberry Pi, type:
cat validator_keys/deposit_data-$FILE-ID.json (replace $FILE-ID with yours)
Copy the content (the text in square brackets), go back to your desktop, paste it into your favourite editor and save it as a json file.
Or
2.- Ssh: From your desktop, copy the file:
scp [email protected]$YOUR_RASPBERRYPI_IP:/home/ethereum/validator_keys/deposit_data-$FILE_ID.json /tmp
Replace the variables with your data. This will copy the file to your desktop /tmp directory.
Upload the deposit file
Now, back to the Launchpad website, upload the deposit_data file and select Metamask, click continue and check all warnings. Continue and click “Initiate the Transaction”. Confirm the transaction in Metamask and wait for the confirmation (a notification will pop up shortly).
The Beacon Chain (which is connected to the Eth1 chain) will detect this deposit (that includes the validator public key) and the Validator will be enabled.
Congrats!, you just started your validator activation process.
CHOOSE AN ETH2.0 CLIENT
Time to choose your Eth2.0 client. We encourage you to run Lighthouse, Teku or Nimbus as Prysm is the most used client by far and diversity is key to achieve a resilient and healthy Eth2.0 network.
Once you have decided which client to run (as said, try to run one with low network usage), you need to set up the clients and start both, the beacon chain and the validator.
These are the instructions for enabling each client (Remember, choose just one Eth2.0 client out of 4):
LIGHTHOUSE ETH2.0 CLIENT
1.- Port forwarding
You need to open the 9000 port in your router (both UDP and TCP)
2.- Start the beacon chain
Under the ethereum account, run:
sudo systemctl enable lighthouse-beacon
sudo systemctl start lighthouse-beacon
3.- Start de validator
We need to import the validator keys. Run under the ethereum account:
lighthouse account validator import --directory=/home/ethereum/validator_keys
Then, type your previously defined password and run:
sudo systemctl enable lighthouse-validator
sudo systemctl start lighthouse-validator
The Lighthouse beacon chain and validator are now enabled

PRYSM ETH2.0 CLIENT
1.- Port forwarding
You need to open the 13000 and 12000 ports in your router (both UDP and TCP)
2.- Start the beacon chain
Under the ethereum account, run:
sudo systemctl enable prysm-beacon
sudo systemctl start prysm-beacon
3.- Start de validator
We need to import the validator keys. Run under the ethereum account:
validator accounts-v2 import --keys-dir=/home/ethereum/validator_keys
Accept the default wallet path and enter a password for your wallet. Now enter the password previously defined.
Lastly, set up your password and start the client:
echo "$YOUR_PASSWORD" > /home/ethereum/validator_keys/prysm-password.txt
sudo systemctl enable prysm-validator
sudo systemctl start prysm-validator
The Prysm beacon chain and the validator are now enabled.

TEKU ETH2.0 CLIENT
1.- Port forwarding
You need to open the 9151 port (both UDP and TCP)
2.- Start the Beacon Chain and the Validator
Under the Ethereum account, check the name of your keystore file:
ls /home/ethereum/validator_keys/keystore*
Set the keystore file name in the teku config file (replace the $KEYSTORE_FILE variable with the file listed above)
sudo sed -i 's/changeme/$KEYSTORE_FILE/' /etc/ethereum/teku.conf
Set the password previously entered:
echo "yourpassword" > validator_keys/teku-password.txt
Start the beacon chain and the validator:
sudo systemctl enable teku
sudo systemctl start teku
The Teku beacon chain and validator are now enabled.

NIMBUS ETH2.0 CLIENT
1.- Port forwarding
You need to open the 19000 port (both UDP and TCP)
2.- Start the Beacon Chain and the Validator
We need to import the validator keys. Run under the ethereum account:
beacon_node deposits import /home/ethereum/validator_keys --data-dir=/home/ethereum/.nimbus --log-file=/home/ethereum/.nimbus/nimbus.log
Enter the password previously defined and run:
sudo systemctl enable nimbus
sudo systemctl start nimbus
The Nimbus beacon chain and validator are now enabled.

WHAT's NEXT
Now you need to wait for the Eth1 blockchain and the beacon chain to get synced. In a few hours the validator will get enabled and put into a queue. These are the validator status that you will see until its final activation:
Finally, it will get activated and the staking process will start.
Congratulations!, you join the Medalla Eth2.0 multiclient testnet!

Grafana Dashboards

We configured 5 Grafana Dashboards to let users monitor both Eth1.0 and Eth2.0 clients. To access the dashboards just open your browser and type your Raspberry IP followed by the 3000 port:
http://replace_with_your_IP:3000 user: admin passwd: ethereum 
There are 5 dashboards available:
Lots of info here. You can see for example if Geth is in sync by checking (in the Blockchain section) if Headers, Receipts and Blocks fields are aligned or find Eth2.0 chain info.

Updating the software

We will be keeping the Eth2.0 clients updated through Debian packages in order to keep up with the testnet progress. Basically, you need to update the repo and install the packages through the apt command. For instance, in order to update all packages you would run:
sudo apt-get update && sudo apt-get install geth teku nimbus prysm-beacon prysm-validator lighthouse-beacon lighthouse-validator
Please follow us on Twitter in order to get regular updates and install instructions.

Reflections on setting up a validator as a genuine complete noob

So this weekend I set myself a challenge of getting a medalla testnet validator up and running. The good news is, I did! The less-good news is, it took me the best part of five days.
One of the things that I found most difficult was that in spite of the many excellent guides that have been written on this so far, none of them (purely in my own experience) have been comprehensive from the perspective of a 100% full noob. None of the guides I followed I was able to make work without issues being encountered of some kind (albeit some minor). This is more a reflection on my own ability, so I'm making this post in the hope that some future expert documentor will take note of some things that werent obvious to me as someone with absolutely no knowledge of Linux or CLIs.
As an analogy, it's akin to reading a recipe where there is an instruction to, for example, 'par boil the potatoes' without describing the process itself for people who dont know what that is. How long for? Do the potatoes need to be peeled? Cut into pieces? Do we add salt? Does the water need to be boiling right the way through? How do we know when done? Do the potatoes need to cool? etc etc.
Some reflections on the experience (not of potato boiling):
  1. Hardware setup: I used the hardware recommendations from u/superphiz in this post. I'd never built my own computer before, but found it pretty straightforward thanks to the power of the youtube.
  2. Guides: I then set about following u/maninthecryptosuit 's guide here, but also referred to approx half a dozen other guides that have been posted on this sub in the past week (shoutout to u/metanull-operator's excellent guide in particular). I really appreciate the time taken by each individual in attempts off their own volition to help the community. I would not be here without those efforts.
  3. Operating System: As per superphiz, I chose Ubuntu Server 20.04 as the recommendation to keep the system as light as possible makes sense. This was the first thing to be set up after building the NUC. It was fairly straightforward to download, although there was a small technical hurdle to format my USB stick to suit Linux from the Mac laptop Ubuntu was initially downloaded to. It was not obvious to me that this needed to be done (although it is now!). Again, Youtube, but recommend that this is at least mentioned in future guides as noob. Although the recommendations in most guides seemed to be to use Ubuntu Server, and I did initially set this up, I eventually ended up starting the process again from scratch with Ubuntu desktop. More on that later.
  4. The command line: this was the first time I'd used a command line interface. At first I genuinely didn't know where to start (as in, literally how to access Terminal and what that is). However, once I got in, it was easy to copy and paste commands (I needed to google to learn about the various shortcuts etc). Sometimes I had issues with copy/pasted commands instantly executing when i wasnt expecting it, and sometimes not. And often the commands were split over multiple lines without that being obvious, leading to malformed arguments. One of the main issues I had throughout was not having a solid understanding how directories are structured in Ubuntu, and how to navigate those via command line... forward, back, checking the contents of a directory, etc. Again more google.
  5. Remote access: The next challenge I had was understanding conceptually at a high level what systems I would be using - as in, am I supposed to be doing this whole process on the actual machine that will be running the validator? I'm going to be saying this a lot, but as a total noob, this was not immediately obvious to me.In fact, what eventuated was that I set up Ubuntu desktop on the host machine, SSH'ed in from my Macbook, where I then did most things. Some guides did cover this to a degree... but I encountered some issues where sometimes I would get locked out due to permissions/keys issues. I wont go into those suffice to say I think remote access/SSH is an area which needs more coverage in guides as it seems to be pretty standard way of doing things. I felt quite satisfied getting that aspect working - it felt like some kind of magic.
  6. Setting up the pre-requisites: in all of the guides there were list of prerequisite things that needed to be set up to get validators etc working (things like git, python, rust, etc). I didn't have many issues here as I was simply cut and pasting commands into Terminal. My main issue was that where things did go awry it was not easy to diagnose why and address. Sometimes I would attempt something one way from Guide A, fail, then attempt a similar thing from a different guide, and not get good results because each guide sets up things sightly different and in different directory locations. As such, I found myself usually contained within one guide for the duration and found it difficult to take advice from the others in case of conflicting instructions.
  7. Setting up ETH1 node, beacon chain, and validator.
This was obviously the most difficult step. Issues:
The first challenge I had was that the order of operations across various guides was not consistent. In some guides the ETH1 node was set up first (or sometimes not mentioned), and in some guides not. In some guides validator keys were set up early, some not. That was confusing to me. There wasn't much narrative as to what needs to be set up first/last and in what order - I get that there is flexibility now, but only after having gone through the process. This led to an issue where in some cases I ran into difficulties, then switched to the corresponding instructions from a different guide (eg setting up a beacon node) but because the order of operations was different, certain things that had already been set up in guide 1 had not been in guide 2, causing the (no doubt very accurate) instructions not to work in my case. Very frustrating.
The reason I felt the need to hop between guides is because there was minimal guidance on how to diagnose issues that arose. Without any instruction on the nature of issues, what do do, what commands to execute to diagnose and fix, I felt my best option was to see what other guides were doing on the same topic in the hope that they gave a steer on how to progress. Not ideal. I recognise much of that was driven by my own impatience - I should have been more methodical in attempts to resolve issues in their current state but it is frustrating to get stopped frequently.
Goerli test ETH: some of the methods recommended to get this were better than others. Prysm and Ethstaker discords seemed the easiest way. There were other recommendations about to tap various faucets many times for tiny amounts of ETH which seemed pretty impractical given we need 32, I'm not sure why they were recommended in the first place.
Validator keys: there is a need to generate your validator keys via the ETH2 launchpad (or CLI). Although generating the keys themselves I found straightforward...
It was difficult to understand how to get my keys from the server into the ETH2 launchpad interface, or conversely from my laptop (where my usual metamask account is) to the server and to tell if actions had been successful or not as there is no immediate CLI feedback. I struggled with this for so long that I gave up in the end and switched to Ubuntu Desktop, restarted the entire process from scratch, just so that I could set up a new metamask on the main machine and drag and drop the files. This was most the most difficult aspect for me of the entire setup... copy/pasting and navigating Ubuntu CLI folder structures is not easy for someone with no previous understanding of the CLI. What I really wanted here was a step by step instruction on how to do this, beyond just "generate your keys on launchpad and send them to your validator keys folder."
After that, I found it fairly straightforward to set up the ETH1 node, beacon node, and validator (I chose Prysm) following the documented steps. I did not succeed initially with the client setup instructions from the ETH2 launchpad and ended up going down a black hole where I eventually got Prysm working via VM, but this caused further issues down the line and contributed towards me starting afresh.
My main issues were around the management of the processes once active. It was not obvious to me what was supposed to happen in regards setting these up in separate terminal windows, and whether or not to leave the terminal windows open. In practice, I ended up closing the terminal windows and was then uncertain on a) whether this had stopped the processes from running and b) how to get them back.
So, the areas I found I wanted more detail on in instructions were:
- what are the processes (Terminal outputs) supposed to look like when they are successfully running?
- what are they supposed to look like while they are running but not yet fully synced?
- how can I check up on the status of these from the CLI?
- if I close a terminal window, how can I get back a live view of the processes?
- what has happened to the processes if/when the windows are shut down?
- what happens if my laptop is shut down but the server is still active?
- what happens if BOTH (or just the server) are shut down and how do I get them back?
All told, I'm super happy and appreciative to all of those whom I have drawn on to get my validator up and running. However I'm not certain at this point that I will be setting this up when it goes live, at least not initially. The main reason for that is that even though I know where to go to get help in working through issues (shoutout and props to ethstaker and Prysm discords!), I have next to no ability to diagnose and fix issues myself to the extent that I feel confident enough in what I'm doing to trust 32 ETH to it. Debugging overall was the main stress. I dont think I would do this again without a stress-tested GUI which involves minimal steps/clicks.
Hopefully that was useful to some people who may have been having similar issues.
TLDR; some issues happened that I couldn't work out how to fix and that was frustrating.
Edit: am going to attempt setting up Lighthouse, Grafana and Prometheus using u/SomerEsat's guide here next.

Ethereum wallet lost? Need help with recovery

Hello, Early 2018 I downloaded ethereum wallet from ethereum and moved all my coins from coinbase to the wallet and forgot about it. Yesterday I tried to open the wallet it but the app itself was gone. It's on a separate hard drive so it hasn't been touched since I moved back in early 2018. Any way to recover this?
On a mac. Don't remember the name of the wallet other than just downloading off ethereum website.
Thanks in advance!
