What events are kicked off when a transaction is submitted?

When a transaction is submitted, it is loaded into the node's mempool. This is like a waiting room for transactions that haven't yet made it on the blockchain. Whether the node is daedalus, or a ...

Are there plans to keep the blockchain/node size small enough to maintain decentralisation?

I assume with "blockchain/node size" you mean the growing size of the immutable ledger database. The current growth rate is pretty linear. In the last 100 days it grew from 7 up to 10.5 GB ...

How to get CLI access from Daedalus installation?

Daedalus has its own cardano-node instance, so you can specify the node's socket variable and use it for cardano-cli purposes. First, launch Daedalus, and click on Help > Daedalus Diagnostics. ...

How long does it take to sync a node or a Daedalus wallet? What factors does it depend on?

It all depends on your hardware, mostly CPU and network connection (yours and your peers), but on most newer hardware you should be able to sync it within a day right now.

I would like to run a relay node on Ubuntu 20 server without creating a wallet, what are my options? Are packaged binaries available?

A stake pool is just a full node with some additional configuration, so the binaries are the same. If you need to run cardano-node, you might want to start with its Getting started documentation and ...

Why is my cardano-node not working anymore?

Killed probably means it was killed by the OOM (Out Of Memory) killer. If it was OOM killed, there will be a message in the dmesg output. Running the node requires at least 8GB and you should have 4G ...

Storage requirements for mainnet/testnet cardano nodes?

Yes, the testnet takes less storage. This is what I got when I installed them a month ago: Testnet: 11 GB Mainnet: 46 GB I haven't updated it again, but it's roughly around those number

You just mean to have all the disk storage the node needs on an external drive? Sure that is possible. How you do it depends on which OS you are running on (eg Windows, Linux, Mac).

You do not need a full node to add metadata to a transaction. Most wallets have this function, for example the wallet Eternl has it.

Why is my cardano-node not doing anything?

Check your configuration file. This looks like your logs are going to a separate file. I've seen this with tools like cntools where they redirect all logging out of stdout into separate log files.
