0) txidopret <- allocation, scriptPubKey, opret
|
|
1) create <- locked_blocks, minrelease, list of txidopret
|
|
|
|
2) fund createtxid amount opretflag to global CC address with opret or txidaddr without
|
|
|
|
3) release amount -> vout[i] will be scriptPubKeys[i] and (amount * allocations[i]) / sumallocations[] (only using vins that have been locked for locked_blocks+).
|
|
|
|
4) info txid -> display parameters, funds
|
|
5) list -> all txids
|
|
|
|
First step is to create txids with the info needed in their opreturns. this info is the weight, scriptPubKey and opret if needed. To do that txidopret is used:
|
|
|
|
./c is a script that invokes komodo-cli with the correct -ac_name
|
|
|
|
./c paymentstxidopret \"[9,%222102d6f13a8f745921cdb811e32237bb98950af1a5952be7b3d429abd9152f8e388dac%22]\" -> rawhex with txid 95d9fc8d8a3ef63693c7427e59ff5e177ef63b7345d5f6d6497ac262699a8def
|
|
|
|
./c paymentstxidopret \"[1,%2221039433dc3749aece1bd568f374a45da3b0bc6856990d7da3cd175399577940a775ac%22]\" -> rawhex txid 00469695a08b975ceaf7258896abbf1455eb0f383e8a98fc650deace4cbf02a1
|
|
|
|
now we have 2 txid with the required info in the opreturn. one of them has a 9 and the other a 1 for a 90%/10% split.
|
|
|
|
./c paymentscreate \"[0,0,%2295d9fc8d8a3ef63693c7427e59ff5e177ef63b7345d5f6d6497ac262699a8def%22,%2200469695a08b975ceaf7258896abbf1455eb0f383e8a98fc650deace4cbf02a1%22]\" -> created txid 318d827cc6d8f25f40517e7fb0982e3f707b4aa749d322483fc336686a87b28a that will be the createtxid that the other rpc calls will use.
|
|
|
|
lets see if this appears in the list
|
|
|
|
./c paymentslist ->
|
|

|
|
]
|
|
}
|
|
|
|
It appeared! now lets get more info on it:
|
|
./c paymentsinfo \"[%22318d827cc6d8f25f40517e7fb0982e3f707b4aa749d322483fc336686a87b28a%22]\"

"totalfunds": 0.00000000,
|
|
"result": "success"
|
|
}
|
|
|
|
There are 2 possible places the funds for this createtxid can be, the first is the special address that is derived from combining the globalCC address with the txidaddr. txidaddr is a non-spendable markeraddress created by converting the txid into a 33 byte pubkey by prefixing 0x02 to the txid. It is a 1of2 address, so it doesnt matter that nobody knows the privkey for this txidaddr. the second address is the global CC address and only utxo to that address with an opreturn containing the createtxid are funds valid for this payments CC createtxid
|
|
|
|
next let us add some funds to it. the funds can be to either of the two addresses, controlled by useopret (defaults to 0)
|
|
|
|
./c paymentsfund \"[%22318d827cc6d8f25f40517e7fb0982e3f707b4aa749d322483fc336686a87b28a%22,1,0]\" -> txid 28f69b925bb7a21d2a3ba2327e85eb2031b014e976e43f5c2c6fb8a76767b221, which indeed sent funds to RWRM36sC8jSctyFZtsu7CyDcHYPdZX7nPZ without an opreturn and it appears on the payments info.
