Bitcoin Core aggressively caches updates to the UTXO database ("chainstate") during its operation, and only occasionally flushes the resulting changes in batch to disk. This happens (a) at shutdown, (b) once per day, or (c) whenever Bitcoin Core runs out of memory (configurable with dbcache= setting). However, when Bitcoin Core is shutdown ...

Better check https://github.com/bitpay/bitcore or other open-source blockchain's indexer. But no bitcoind is not made to support this "top level" functionality

This is not a supported feature. Only the wallet tracks total balances (per wallet even, not per address), and only does so for your own keys/addresses (including imported "watch only" keys/addresses). Other software exists that provides this functionality.

If you have no money, you might just install virtualbox and put a Linux node on it to download bitcoin core (details for installing this free software are in Antonopoulos' book "Mastering Bitcoin"). But this will not be fast enough to actually mine bitcoin (well it will dig but unlikely to win any blocks at the current difficulty level)--you could ...

There is no need to truncate it. You can just start Bitcoin Core with the -reindex option. If you do, it'll throw away the UTXO set and other databases, and rebuild it from the blocks you have on disk (which will be kept), up to the point where they're corrupt. It'll take a while (possibly nearly as long as synchronizing in the first place), but it won't ...

This is expected. which only searches for binaries in your $PATH variable (e.g. it needs to be placed in /usr/bin or /usr/local/bin for that). If you didn't put bitcoind there, you'll need to invoke it using the pathname (e.g. ./src/bitcoind in the directory that holds it).

addressHash is the data output by pybtc. The data is a hash of the public key or script. It is contained in the address. And also parts of scriptPubkey(locking script). For P2PKH and P2WPKH, it is Hash160(public key) For P2SH, it is Hash160(script) For P2WSH, it is SHA256(script)

You can run a C-lightning instance on top of a pruned bitcoind. You can also opt in to a different Bitcoin backend than bitcoind by using a plugin. For instance the Sauron plugin connects to an Esplora instance, this is a more lightweight way to get started albeit you are trusting whoever operates the API. A lightweight solution seems appropriate for testnet ...

I am thinking of running my own lightning node in testnet. Going through the tutorials it seems the lightning node needs to be connected to bitcoin node inorder to get connected to bitcoin network. But running a full bitcoin node like bitcoind seems out of my scope as I don't want invest and maintain it. A Bitcoin testnet node block chain occupies less than ...
