I want to run a Stake Pool

HazelMazel3 · 8 February 2018 21:55

Guys, It’s not a secret.

I started with the standard AWS Ubuntu. I updated and upgraded everything.

Then I followed these instructions:

input-output-hk/cardano-sl/blob/develop/docs/how-to/build-cardano-sl-and-daedalus-from-source-code.md

# How to Build Cardano SL and Daedalus from Source Code

This manual describes how to build Cardano SL and Daedalus from the source code.

## Cardano SL and Daedalus

Cardano SL consists of a collection of binaries that constitute
the backend and the Electron-based wallet called “Daedalus”.

The source code of Cardano SL can be obtained from the
[official repository](https://github.com/input-output-hk/cardano-sl).

Cardano SL supports two ways for building itself:

-   (preferred) [Nix](https://nixos.org/nix/) package manager (backed by a binary cache by IOHK continuous integration)
-   [Stack](https://haskellstack.org) with Nix for system libraries

In any case, we strongly suggest using [Nix package manager](https://nixos.org/nix/download.html)
to get the correct dependencies for building Cardano SL. It will fetch the correct `openssl` version,
but won't override the system-installed version. The following commands assume that you already have

This file has been truncated. show original

Read the whole document before starting. There are 3 ways to do it. I did it the first way - using Nix.

Then do these instructions to make the script so you can run:

github.com

input-output-hk/cardano-sl/blob/develop/docs/how-to/connect-to-cluster.md

# How to connect to cluster

1. Make sure you’ve follow [the instructions to build from source using Nix](build-cardano-sl-and-daedalus-from-source-code.md)
2. Make sure you’re on latest `cardano-sl-X.X` branch
3. To build a script that will contain everything needed to connect to mainnet: `$ nix-build -A connectScripts.mainnetWallet -o connect-to-mainnet`
4. Alternatively you can connect to different environments and different executables by building the scripts:
- Explorer node with mainnet: `$ nix-build -A connectScripts.mainnetExplorer -o connect-explorer-to-mainnet
- Wallet to staging: `$ nix-build -A connectScripts.stagingWallet -o connect-to-staging`
- Explorer to staging: `$ nix-build -A connectScripts.stagingExplorer -o connect-explorer-to-staging`
3. A runtime state folder will be automatically created relative to your current
   working directory, but you can override it using `$ export CARDANO_STATE_DIR=~/wallet-state`
4. Run the script: `$ ./connect-to-mainnet`
   Or run `./connect-explorer-to-mainnet` if you might want to connect anything listed in 4.

cf_ that means you work for the foundation and know stuff right?

Two technical questions:

How sophisticated will the delegation of stake be. If my pool goes offline, am I just stuck with that, or can it roll over to a second, third, fourth delegate? This makes quite a bit of difference to the people who are planning to run pools, in terms of the amount of redundancy they need to incorporate.
If I delegate to a stake pool and that pool produces a bad block, I lose all my money - correct? This seems fair if it was intentional, however I think it is very likely that at some point this happens accidentally, memory corruption or something like that. Has this scenario been considered?

Many thanks,
M.

Why Nix is preferred:
Nixos-stack2

For all you Debian/Ubuntu, RHEL /CentOS users out there, check out running nix on a lightweight chroot (unprivileged user) container on any system.

Big HINT, no matter which Linux version you decide on you should adjust your filesystem for Cardano's blockchain and meta-data.

Cardano’s blockchain contains many small files, to accommodate that reality we optimize the ext4 filesystems defaults:

Example during install:
Note - your /dev/sdb path will be different, probably.

mkfs.ext4 -b 1024 -i 1024 -I 128 /dev/sdb

You should then assign your “home” disk to /dev/sdb

mount /dev/sdb /home

Home will then serve up Cardano’s blockchain in the most efficient way possible.

It would be good to know the answer to these questions.

@MARTIN_SMITH Hello Martin!

It does mean that I work for Cardano Foundation, as to being the font of knowledge for technical aspects, not so much

I’ve made a note of the questions and will get back to you

Kind regards,

Jon

Hi @MARTIN_SMITH - staking right now is under development. The delegation team are making good progress though and we and IOHK will be answering specific questions as soon as we have accurate and firm answers

madsravn · 13 February 2018 09:01

Is there a place we can be written on a list so you know we want to participate? Charles talked about that in one of his videos.

MARTIN_SMITH · 13 February 2018 20:29

Thank you, perfectly reasonable reply.

Rohan · 14 February 2018 21:54

Hi @madsravn we are all eagerly awaiting more information! We are expecting stake pool registrations to start soon to take part in a testnet. This could happen soon (this month), but will depend on IOHK’s Shelly development progress. This forum will be notified as soon as more details are available - stay tuned!

ThePMC · 19 February 2018 18:59

Hi, I’m interested in learning more about your ADA stake pool. Thanks!

I intend on applying to get a node. Not much more I can say. Everyone right
now is making empty promises since applications aren’t even out yet. There
are going to be a lot of people stuffing the application box to try and get
one of the 25-50 slots. I’m going to do my best stand out, I think I have a
good shot at being selected but going into the reasons why publicly at this
time would be detrimental since its anticipated that the application
process will be competitive.

HazelMazel3 · 19 February 2018 20:42

What is the reason for the 25-50 limit? I would have thought you would want as many as possible.

If CF are taking themselves out of the equation, and lets say there are 30 nodes, then if someone takes out 16 nodes, network stops.

NinjaPool_io · 19 February 2018 21:07

20-100 limit is only for the testing phase. Once Shelley is released we expect no limit to the number of staking pools. IOHK will encourage pools/nodes to drive decentralization and secure the network.

Chainomatic · 19 February 2018 21:19

There are no limits once Shelley goes live.

Only so many hours in a day, want to get node operators who know their way around Unix/Linux before opening the door to all.

t_mes · 20 February 2018 01:04

I cant speak to IOHK’s reasoning. There will be more later but this is the
starting point

opanai · 20 February 2018 18:41

does it mean when you follow this steps you’re already running a node? Will it be the same steps when Shelley goes live?

seeting · 25 November 2018 02:10

I concur and trust it is the situation. Assuming this is the case, expenses ought to be minute since there are no huge expenses or obstructions, which is perfect for selection of the tech regardless of whether a portion of these salivating pool-administrators to-be are frustrated.
I plan on applying to get a hub. Very little more I can state. Everybody right
presently is making void guarantees since applications aren’t level out yet. There
will be many individuals stuffing the application box to attempt and get
one of the 25-50 spaces. I will do my best emerge.
