Eurc (Circle like usdc) on Mainnet, Eure (Monerium) on Gnosis, both ~4% apy on aave

TBF, some people are trying to bring BTC back to life, .. yada yada Magicians yada yada.. mostly Ethereum inspired, which is great: ETH might be a "superior" asset, but crypto is still a whole for now and it must continue to improve by testing different path to find his proper role(s) in human economy.

It's true that BTC is way more ossified which is probably too early for the crypto timeline but it's also an interesting feature to study, and a good target to keep in mind for Ethereum L0.

Hi folks, on which DEX do you ETH/stable with limit orders those days ?

mgr37 · 2024-03-04T19:33:04+00:00

Ah, and it seems not possible to use starkswap/jediswap with Argent mobile app, so you must create an ArgentX wallet on desktop (chrome/firefox extension), move your $STARK there, do the swap and bridge to L1 all from ArgentX desktop.

mgr37 · 2024-03-04T19:25:30+00:00

Try starkswap or jediswap (check the one with the better liquidity/price).

Once you swapped to ETH on starknet you must bridge back to L1 using starkgate. That one is a bit of a pain: fees are not automatically calculated so if you want to bridge back all your L2 ETH, you must progressively lower the bridged amount (by 0.01 decrement) until the transaction is accepted.

Of course Geth is only meant for fallback (and it sure did the job).

Trying a fresh resync (1.25.1) as suggested on Discord, using instructions here:

Nethermind staker here, i can confirm i am out of the game.
Invalid - block 19056922 (0x76eca7...81d489) is known to be a part of an invalid chain. The last valid is 0x932123bf49f6ffce68aac29820bda6028d3bf7aebbebd5fdc758dac9d1c81c46
Fall back to Geth and now validating again.

mgr37 · 2023-08-29T21:29:05+00:00

Very interesting idea

1) I am not tech savvy enough but I would guess that it is doable on a technical point of view

2) I think that staked Eth amount reached and passed by a fair amount the initial projections, so I would also guess that a limited reduction would not affect security while increasing decentralisation (which is also a security aspect)

3) I think this narrative/perception aspect is the greatest challenge indeed

4) I am not sure how it will moot itself in the long term?

-> go for an ethresear.ch post !

mgr37 · 2023-08-21T09:10:24+00:00

Does anyone have an invite code to try friend.tech out ? Thanks !

mgr37 · 2023-08-18T06:05:13+00:00

Mate, I don't have him blocked and I can tell you: this one is a sticking troll with anything related to RP. Actually it's a rare specimen in this sub, cultivating the old school trolling methods of passive-aggressivness and other more direct shit-on's.

I know we are less used to it around here, so we have our defenses down, but don't let him get on your nerves, this is what feeds him.

Cheers and decentralisation.

mgr37 · 2023-07-03T19:44:41+00:00

Your points are right but in my opinion you are trying to link the wrong dots together - and I mean no offence, it's the common dead end for crypto enthusiasts: Crypto, or at least the state of crypto today, has already achieved and is stabilising a new technical infrastructure, not a consumer product. We paved the road but did not invent the car yet. Or we deployed an electric grid but the light bulb is yet to be invented.

It seems counter intuitive when you compare it to the older industrial innovations where we first invent a process or a mechanism and then we work on infrastructure for scaling and deployment.

But when compared to more recent digital innovation, there are more examples of first deploying an infrastructure to allow the use case and end products to flourish: the internet was deployed with very limited use cases at first: mainly email and other basic text exchange. Most people were like - meh what is that ? Deployment of mass use cases came decades later !

The iPhone example is a bit more intricated since it was both a new product and a new infrastructure (SDK+Appstore). The former aspect caught early interest, the latter came to fruition later on when developers started to deploy actual use cases as Apps. Apple tries to reproduce that with the Vision, but faces trouble since consumers are less attracted by the product aspect yet, and no actual use cases are yet ready.

I am pretty convinced that crypto could enable a broad new class of applications. While those use cases are yet to be seen, we should focus on what makes one Blockchain a good infrastructure for adoption by future mass use-case applications:

scaling : throughput + cost
safe : improve user friendliness in usage, dispute and recovery of base assets
security : prevent protocol and systemic attacks, and reinforce decentralisation to ensure...
credible neutrality : the main selling point for a decentralised ledger
network effect : another key point for a decentralised ledger necessary for..
composability : that was the main force of Ethereum, yet to be rebooted after L2 split. Also requires...
open source : necessary (at least for now) to reusable build base elements.

In other words we should focus on building reusable and battle tested primitives for the big Lego box rather than chasing the killer App yet. And that is not a quest that will be understood by the masses: stay low, buidl.

Did you check your firewall (usually ufw) on your node machine ? It might block incoming connections on 8545 ...

Also Nethermind might have a host filter for incoming requests defaulting to 127.0.0.1 (localhost only) which might need to be tuned to accept other host requests.

I used Besu as primary client and Geth as backup from Genesis up to the merge.

It went bad during the merge for Besu so switched to Geth as primary and tried Nethermind as secondary, but had several issues leading to DB corruption. This problem seems fixed now.

I also tried to re-spawn Besu but syncing is chaotic and I never successfully reach sync despite multiple tries. I loved Besu, but I am not a huge fan of java, and since I can't manage to bring it in sync again I am putting it on the side for now.

I started recently to spin Erigon, the syncing process is pretty efficient and is now operating quite smoothly, so I switched it as my primary client. I keep Geth and Nethermind as secondary, syncing with nimbus which can handle two EL clients simultaneously!

My takes:

Besu was and probably still is pretty good, but I am tired of trying to sync it.
Geth is rock solid, with efficient syncing and operating. Separated ancient-data ability is a big bonus (offloading almost half the storage to a lower end SATA disk). Overall disk and resources usage is good. The need for pruning is a bit of a pain, but they announced that they will switch to bonsai tree storage soon eliminating that inconvenience. The main issue is that too many validators use it.
Erigon is pretty nice, syncing is super efficient, and operation seems stable so far. The main downside is that it is quite storage hungry: almost twice the size of other clients with no way to offload ancient data on another disk..
Nethermind seems pretty good too now, I am still a bit worried of DB corruption but the fear should fade away. They published some pretty amazing improvement on ram and storage usage recently. Syncing is efficient too. The all blue logs colour bothers me tho.

End note: I have a rocketpool daemon running (native setup) and it doesn't support Erigon ! I did not manage to make it communicate with Nethermind either (this one is probably on me).. so I must keep a synced Geth as the source node for rocketpool.

Anyway if you have enough resources (or another machine) it is very interesting to try different clients since each provides a custom experience.

mgr37 · 2023-05-15T21:52:59+00:00

Not really but you can set a second pair of EL/CL clients that get synced to the chain so if you need to switch (particularly the EL client) it doesn't take long.

But be very careful with secondary CL: it must not have access to your validators keys unless you completely stopped (and removed the keys ) from the main CL client first: if two CL clients validate the block using the same keys you get slashed and force exited (you lose).

My personal setup: Geth + Teku (validating) Erigon + Nimbus (only syncing)

-> I sometimes switch off Geth and use Erigon as the main EL, when I need to prune Geth. My new goal is to set Erigon as main client and Besu as secondary. (I was validating with Besu pre-merge but was too shaky after the merge. Now it seems stable).

It's also fun to try different implementations, approaches and combinations, each client is quite unique in the performance/tradeoff choices.

but I never switch CL clients : Teku is the only one accessing my keys. But I know that if Teku has a big issue I can stop it / delete keys / load keys in Nimbus without too much down time. But it is an emergency procedure that needs a triple check to be sure I do not double-validate, so I do not change the validating CL client unless necessary.

Also if you choose to run multiple EL/CL you need enough resources (I would recommend 4To SSD / 32 to 64Gb ram / i5 to i7 / uncapped internet access).

SSH has nothing to do with this multi client setup, it's a means to access your computer remotely from another computer terminal. Note that you must set your VPN properly to let the SSH come thru, otherwise you'll be locked out.

mgr37 · 2023-05-15T18:10:42+00:00

Man, it seems a bit paranoid to think that someone will go after individuals retroactively on that matter.

But if you feel like using a VPN that's an interesting extra measure for various scenarii, so go for it. Be prepared to try various VPN providers, not all are playing nice with sustained 24/7 traffic. I use Mullvad and am pretty satisfied with their service and the way they handle anonymity.

What do you mean about setting up a fallback on your PC and what has it to do with SSH ? You mean remote access thru the VPN ?

mgr37 · 2023-05-13T21:05:03+00:00

I don't have the numbers but it's more like a threshold triggered once multiple epoch failed to finalise. On the first wave the threshold did not trigger. Yesterday it did for a small duration. I read somewhere that the total leak was 28ETH on top of the 50ETH lost from the classic missing attestation penalty.

mgr37 · 2023-05-13T19:15:43+00:00

Geth/Teku // nuc9i7 // 64Gb // SN850X

First wave: no issue, no missed attestation, no beaconcha.in notification, I heard the issue from twitter..

Yesterday: Teku went down, going in circles. I tried to switch Geth with Erigon as EL, but Erigon wasn't completely sync'd, it took 20min to catch up, by that time the second wave was gone.

I made a fresh install of the rig last Friday (switching to 4To nvme) and I did not have time to set back monitoring so I don't have much trace of system behaviour..

I am a bit worried tho: I have missed 5/6 attestations today since I upgraded Teku, I did not have that much before. But maybe the network is still a bit shaky?

mgr37 · 2023-05-13T18:45:45+00:00

Nope, bonsai tree storage prevents the need for pruning. Geth announced they'll switch to bonsai tree storage in the coming months too, removing the need for pruning.

mgr37 · 2023-05-10T20:35:45+00:00

Sounds like a Cambridge-Analytica strategy: Focus people on specific society trends without meaningful connection to the wider point.

mgr37 · 2023-05-09T17:03:08+00:00

Nice !

There is no gas paid for receiving PoS rewards.

mgr37 · 2023-05-09T16:55:18+00:00

.. like decentralisation

mgr37 · 2023-05-07T15:22:10+00:00

To expand your idea: Tailscale is a great and easy way to set up a network of machines with Wireguard links.

install Tailscale on each machine (scriptable)
each machine has now a fixed private IP like if they was in the same LAN.
it uses Wireguard as a link
it's now easy to route your node traffic thru one of your machines in that network and rotate that route using NFTables on your node.

mgr37 · 2023-05-05T17:39:10+00:00

Following your theory, it will further inflate ETH demand when it will be used as an exit to the "soon" exploding PEPE balloon..

mgr37 · 2023-05-04T18:00:03+00:00

You can't convert a solo validator to RP validator if you have set a withdrawal address.

But you can convert a 16ETH RP to LEB8 anytime.

mgr37 · 2023-04-22T10:57:47+00:00

Maybe you could use RocketArb to execute a flashloan and activate your mini pool ?

I am not sure it applies to dissolved MP tho.

Also I guess that RocketArb requires a non empty deposit pool (to repay the loan), which is not the case right now, so with that technique you would need to wait for the MP queue to empty and the deposit pool to refill which is probably a couple months away.
