cashscript VS Fulcrum

https://cashscript.org/ (check out the guides!)

CashScript is similar to solidity, but writing contracts for UTXO chains is slightly different than for EVM chains since you don't have global state, just utxos.

This is a stripped down example from p2pkh.cash showing a simple authorized address example:

Closest is probably cashscript. I believe they are currently working on these for the May upgrade this year

This app was built using the Cashscript route. So the contracts are written in a solidity style language and then transpiled to BitcoinScript. They're fast to write and easy to read, HOWEVER, if you step through the actual bitcoin script, you'll often see a number of things that are not optimal. There is a playground for CashScript: https://playground.cashscript.org/

I should clarify that by examples I mean working code that can be run by itself as a demo. For example, the next.js repository has a very large collection of examples for integrating next.js with various tools and frameworks. You can also see these type of examples in the cashscript repository as well as in the bch-js repos

Fulcrum. Fulcrum requires more resources than romanz/electrs but it can still run on a Raspberry Pi, and it handles heavy queries much more efficiently. If you're having issues with romanz/electrs, Fulcrum is worth a try.

https://github.com/cculianu/Fulcrum (Electrum server, most wallets rely on it to find UTXOs belonging to addresses)

I am not familiar with EPS so the only thing I am going to suggest is to try Fulcrum which is another electrum server implementation and it's super fast. After setting it up, I let it sync and build the database (it took 8 hours) and now I can connect both Sparrow Wallet and BlueWallet to it both via Tor on port 50001 and SSL on port 50002 with the self-signed certificate I created.

How will you be using the node? FYI for a lot of use cases, an SPV friendly indexer like Fulcrum (high performance version of Electrum) will work, for example through the JS library Electrum Cash. There is also the massively powerful but also heavy ChainGraph. There is also Bitcoin Verde node which uses a SQL database for storage which is nice if you want that. Etc. But yeah, sucks about BCHD for now.

That's you running for example ElectrumX or Fulcrum, or any other Electrum-server implementation on top of your bitcoind.

Or you can run an electrum server on top of bitcoin core, which is what I do. I use Fulcrum, because it's really easy to install. Then you can point your Electrum wallet (Android or PC) or Sparrow (PC) or BlueWallet (iOS or Android) to your own electrum server.
