cardano-wallet VS plutus

It's definitely possible to pass this cost on to the buyer, I would personally start by getting the cardano-wallet stack running. If you're familiar with docker/docker-compose this is quite easy: https://github.com/input-output-hk/cardano-wallet/blob/master/docker-compose.yml

pkgname=cardano-wallet _version=2021-09-09 pkgver=20210909 pkgrel=1 pkgdesc='HTTP server & command-line for managing UTxOs and HD wallets in Cardano.' license=('Apache') arch=('any') url='https://github.com/input-output-hk/cardano-wallet' makedepends=('cabal-install-bin' 'ghc') source=("https://github.com/input-output-hk/${pkgname}/archive/v${_version}.zip") sha256sums=('868247f4a628d0d53ebfcd11bb0969ac2f22aa5579349484b1f3907497d11200')

It's not so bad. I wrote an IRC tipping bot for Cardano, was thinking it's gonna be extremely complicated, because I don't know any haskell, but it was actually pretty easy. Low level tools like cardano-cli and cardano-wallet allows you to build pretty much anything around them and all you need is to parse JSON and process HTTP requests, but it has its catches - for e-commerce I think biggest issue right now is inability to generate "unlimited" amount of receiving addresses via cardano-wallet - https://github.com/input-output-hk/cardano-wallet/issues/2921 it could be worked out by using transaction metadata, but then that's something that most wallets doesn't support right now.

I've looked at cardano-wallet but I think it's for only making transactions that are made on your server?(sorry if this isn't correct). Is there a service where they can take the address of one wallet and send to another wallet that wasn't made on your server? Or is that what the new smart contract roll outs are for? Thanks

Plutus (Haskell) is a statically typed programming language wired for writing reliable smart contracts on the Cardano blockchain. It is also a functional programming language, which means programs are composed as sets of mathematical functions for execution.

There's quite a few recent Isabelle repos such as https://github.com/input-output-hk/high-assurance-legacy

I haven't worked there for a year or so and don't remember specifics like KLOCs, just that they're dotted around internal and public repos :)

PR for Improved Rational for on-chain size was merged into Plutus: https://github.com/input-output-hk/plutus/commit/6d8d25d1e84b2a4278da1036aab23da4161b8df8

Cardano also suffers from the issue of the size of Plutus script being too big. One script can eat up to 20% of block which renders the overall efficiency even worse.

They're working on script libraries where you can reference a script in another UTXO rather than having to reinclude it every time. This is mentioned in some videos (I think in November's mid month update and Cardano 360), if you don't have time to watch those it's mentioned in michaelpj's comment here along with some other optimisations they're working on https://github.com/input-output-hk/plutus/issues/4174

There is a discussion on GitHub about this. The second solution in MPJs reply is what you are suggesting.

About to say that lol. Here are more info.https://plutus-apps.readthedocs.io/en/latest/index.htmlhttps://github.com/input-output-hk/plutushttps://docs.cardano.org/plutus/learn-about-plutus
