ANP with 2nd walkthrough video

In this video I share with the viewer some of the experiences I have had with my time in the Friends and Family testnet period for cardano-node and walk the viewer through making a node certificate, creating staking keys and as bonus contents we look more into docker swarm, pro’s and con’s of docker containers for cardano-node and community scripts.

Here is the link:

ANP creates cardano-node scripts for learning purposes

They say one of the best ways to learn how something truly works is to build it from the ground up. So I took that to heart and decided to build some scripts instead of using some of the other great scripts out there. And I could not resist putting in some ASCII for ANP logo in there as well 🙂

ANP joins friends and family testnet and adds hardware based encryption for cold staking keys

Ada North Pool had the great honor of being asked to join the friends and family testnet. The TLDR is the progress is great. Overall the experience has been great and documentation, features and overall experience is shaping up well in the opinion of this pool operator.

We also added a hardware encryption usb drive in preperation of cold staking key storage.

View of a core node and a relay as of today 14th May.

The nodes come prebuilt with a lot of features that can be enabled. For example the EKG view that you can set to a port on your localhost.

With a Prometheus exporter built into the node it is really easy to setup Grafana data as well.

ANP New server/node structure overview and update on [email protected]

An overview of the latest node structure for Ada North Pool (ANP).

To end the testnet with a bang we have upped our efforts even more. We added two Germany based xeon 4core computers on 1gb fibers at one of the datacenter of Hetzner where we are now both [email protected], practicing with cardano-node swarm (manager/[email protected]) and also adding block propegation for jormungandr to improve our chances of winning slot battles. For our home servers we have a local swarm on its own network (lan based) for the cardano-core that is in touch with the cardano relay nodes (in ip addresses and and also the remote servers @ relay3 and relay4) and thus should work fine even if one of the internet falls down. We also have full UPS backup in both the home servers and in the datacenter. I think we are now on a path to become far more secure in our operations even in the event of internet failures or power outages.

[email protected] is going solid with participation previously by the whole ANP family of computers. Onwards we will be using ANPLAPTOP (4 core) ANPSERVER2 (its a 12 core so have idle capacity for this) Both the ANPHERTZNER servers (4 core) + ANP FAMILY computers that are 8 core and 4 core and with GPU computation as well.

We are currently participating with a good deal of computation for the Cardano team. Stats can be viewed @
Main jormungander server with a pool and 6 nodes.
The main server also hosts a core cardano-node (2nd network lan) and a cardano-node relay (internet)
ANP server 2 hosting 4 cardano-node relays. Server is also [email protected] on light setting.
ANP Hertzner servers the two cardano-node relays are up and running. The jormungandr propagators one is up and other is boostraping soon to be up as well. Both ANP Hertzner servers also run [email protected] on light to help support the cause.

Today the first batch of equipment for our second server arrived. We are considering naming our second server oro8 after the Oroborus snake of life/death cycles with the 8 symbolizing the eternal ring cycle. But probably we will name it ADA NORTH POOL 2 (ANP2). Main server will use Ubuntu for stabile operations while the 2nd server will use the more rolling updating distro called Manjavo for faster implementation of new kernel/hardware support. The stable server will likely host the pools and the more rolling updating server will hold a majority of nodes (but both will run nodes).

It has been quite a ride for ADA North Pool and as a staking pool operator I have learned a lot during these 109 days. I am grateful for the trust delegators have put in my pool and I hope to continue improving also for the main net. Thank you to every delegator who made it possible for ANP to produce 2000 blocks during the ITN.

ISPPA – Inter Stake Pool Peering Agreement

In spirit with the Cardano incentivised testnet and experimenting on models of pool operation several pools have together formed an “Inter-Stake Pool Peering Agreement”

In total these pool operators have produced well over 42000 blocks all together and have proven over time to be reliable pool operators securing 24/7 operations of their pools. For comparison this is roughly the same size as all the blocks produced by the largest multi pool combined. On average the pool operators produce around 12% of the blocks in the network in any given epoch.

The main intention of this agreement is to test for and try to achieve an even better networking infrastructure and propagation of blocks than with each pool operator running on his own during the ITN. It involves connecting the pools and relay nodes as preferred meaning that these nodes will form a huge cluster located all over the world that will be constantly inter-connected and exchanging data. The preferred option technically adds a fourth layer of communication on top of the 3 communication layers of Cyclon, Rings and Vincity. It does not mean that the pool operators are going to exclude other pools from their information flow as we are firm believers in decentralization. It also does not mean the operators are running a common business but will stay independent entities.

Finally as this is an ITN we hope to collect data and see if this model of operation can give improvements to the already steadily improving network of Cardano nodes all around the world! We will welcome collaboration at a later point but for now want to keep a steady sample size to compare data.

ADA North Pool Video introduction and update on server

So encouraged by Charles post on staking pool making videoes I created one today that you can find here

Currently I just need to do some cable managment but as you can see we are running straight from ISP to pool.

ANP Installs dedicated fiber connection

In these Covid-19 times trival news like this is perhaps not that important but it is an important milestone for ADA North Pool. Today we connected a 1 gigabyte dedicated connection straight to the pool’s Mellanox network card this should help tremendously with capacity as we can now fully unleash the 1 million tcp packet per second capacity of the network card.

I got word from the 2nd fiber provider (Homenet) that they are coming to install the fibre connection in week 11. That means we will have more redundancy for ANP with one fibre connection dedicated and connected straight to network card and the home fibre connection as a 2nd fibre connection. This should help with robustness for the server and is a stepping stone towards also full redundancy with either 5G or Starlink internet whatever is provided first. (likely 2021-2022).
