research VS AutoCove-Plugin

It is non-custodian betting on price of supported assets paired against BCH, both parties put their money into the contract's pot and later the contract parses an oracle message and calculates how much they can take out. Made possible with Introspection opcodes and int64 upgrades to Bitcoin-tech Script VM, which activated in May '22 on Bitcoin Cash blockchain.

I dug around a bit and it seems to be this one: CHIP-2021-02-Bigger-Script-Integers.

native introspection

The latest "Group" proposal (v4.2) is more than just "tokenization". It got simpler and more powerful at the same time. It now enables generic BCH output groups that can be used to create persistent Script covenant contracts that can prove their genuineness. This is something that current contracts cannot do, even with the new Introspection opcodes. Group would make it possible because the groupID is a commitment to the whole genesis transaction, but this is not a post about that.

Will you soon shut up about BCH being shit against "superior chains" when I point you to the CHIPs such as Native Introspection Opcodes, Bigger Script Integers which allows better smart contract functionality coming in 2022, and PMv3 and Group Tokens which allow better token and transaction formats that are coming in 2023?

You can't, because it requires a sibling output (same prevout txid as the contract, but index 1 instead of 0) to be spent alongside it and it verifies it using introspection opcodes that will be available in May. Only the owner of the sibling can spend the contract.

Electron Cash, since it has plugins. CashFusion's an example (internal plugin). I've released a couple external ones for fun (VanityTXID & AutoCove). A plugin can do anything if people edit the qt.py file inside the .zip.

Here is the hex if anyone wants to see it in AutoCove: 5479009c637cb1755479a9537a88537a011f7f7c01177f7b01197f00cc537a819d00cd537a8851cc7c819d51cd87777777675479519c63c3529d00c7827701179d00c700c658807e51c7827701199d51c6021027a26951c751c602b0049458807e7ea900c651c6930258029401147b7ec101157f777e00cc7b9d02a9147ca97e01877e00cd886d6d755167547a529d00cca1690376a9147b7e0288ac7e00cd8777776868

You could've used 2* OP_CODESEPARATOR. The pReturn... v1.1.0 Script I released today for AutoCove has 18% lower fee with a CODESEPARATOR. Here is the RefreshTimer hex to decode in Electron Cash v4.2.6:

Electron Cash has dark theme, too, but it has some color issues. I've released a plugin (AutoCove) that toggles B&W backgrounds, with colored Script. I dunno if the Android version of EC has the dark theme.

I've released an update to AutoCove (EC Script plugin) with asm & dark-theme support, an op-counter and TXID lookup. However it still needs another update.

The plugin's GitHub has the AutoCove-Plugin.zip needed to install it into Electron Cash. I last posted a video of v1.0.3 decoding some popular Script types. That version was missing Native Introspection & OP_REVERSEBYTES. The decoder now accepts whole raw txn input, and spelling can seamlessly switch between OP_CODES & codes etc.

For anyone interested, here is an auto-decode from State 52's pay-out (I need to think about the formatting):

I last posted after v1.0.2 introduced color. v1.0.3 can be downloaded from GitHub here. After someone spends from any address starting with p or 3, the Script hex can be copy-pasted from block explorers into the plugin, so that the Script is made more readable, e.g. with colors. It could be a nice way to check how smart contract plugins etc work, inside Electron Cash.

OP_RETURN could provide an elegant way to make automated payments. The contract address can auto-pay the receiver after a particular time (e.g. weekly rent payments). We need at least one node to query all OP_RETURNs to keep track of all new contracts. The auto-payment can be made using PrivKey=1. I've been developing AutoCove, but it's not powerful enough.

The v1.0.2 release is at GitHub. The .zip can be installed into any EC wallet, to play around with OpCodes. I'm really not sure what the colors should be. On the one hand, lines can start with green since that means go, but on the other hand the start of a line is when we have to stop & think about them. Then I wonder how next year's OpCodes will be colored...
