cardano-db-sync VS nix-config

Do check out cardano-db-sync which has a docker-compose file that utilizes cardano-node.

Where are the instructions for building cardano-db-sync? https://github.com/input-output-hk/cardano-db-sync/blob/master/doc/building-running.md

There are a bunch of examples in the cardano-db-sync repository link to interesting-queries.md

Continuously sync chain to PostgreSQL using official script * https://github.com/input-output-hk/cardano-db-sync.

Your best choice is running a cardano-db-sync and make queries to the postgres database: https://github.com/input-output-hk/cardano-db-sync/

So what did I do so far: I followed this instruction(https://github.com/input-output-hk/cardano-db-sync/blob/master/doc/docker.md) and had a cardano-node, a cardano-db-sync and a postgres isntance running on docker. I was able to successfully connect to the postgres database. However, I was not able to find recent transactions even thought the blockchain was up to date. When I took a close look onto the docker console I saw that the cardano-db-sync_1 process continuously exited with code 126.

https://pool.pm/whales is useful for when whales change their delegation, but what you probably need is cardano-db-sync which basically follows the chain and dumps information into PostgreSQL.

That explains why it works so well as a persona filter.

If you use NixOS with flakes, you literally just change the revision hash in a flake file and press compile and your whole system updates and compiles as if you had installed that new version (with all of its dependencies regardless of how much they've changed) with a Docker-esque guarantee that everything is configured properly. I have a full NixOS confg with Cardano Node here if you'd like a starting point.

If you’re curious, simply run it on a VM if you’re too scared to hurt your daily driver: https://github.com/harryprayiv/nix-config My plutusVM branch runs a tiling window manager (xmonad with polybar) and has all kinds of cool features that just work ever since I got them setup.

It pulls down a json file from an api link, pipes that json into jq to extract the relevant info, then filters it through sed to get rid of the quotes. I'm pretty proud and wanted to share since this is my very first custom module. Here's a link to my NixOS config with it working flawlessly.

I forked and customized a fairly advanced Nixos configuration that I can load from a flake on github. (Mine | Original)
