How this works:
- earlytxid must be a transaction included in the chain before block 100. The chain MUST not have any other of these type of tx before block 100, or someone may be able to change it and mess things up.
- When it gets to block 100, it takes the txid specified by the -earlytxid param (does not affect magic)
- Looks up the transaction searches for the opreturn, then permenantly appends it to the end of ac_script in RAM.
- After every daemon restart, the first time the daemon mines a block, or receives a block that pays ac_script it will look up the op_return and save it again.
- this enables it to always reach consensus but doesnt need to constantly keep looking up the tx in the chain.
- The trick is to use ac_founders=101 or higher so that nothing is ever paid to the unspendable CC address. Although it should still work without this it burns coins.
-ac_script can be any Global CC address you can spend to with an OP_RETURN. Here we use example of paymentsCC being used to fund a rewards plan, and a set of founders address's.
you can get the ac_script from another chain, but the op_return payload must generated on the chain itself. this command gives you the needed info to get the scripPubKey Hex:
./komodo-cli -ac_name=TEST paymentsfund '["5d536f54332db09f2be04593c54f764cf569e225f4d8df5155658c679e663682",1000]'
append: b8, to the end of ac_script, this changes magic value for -earlytxid chains vs normal ac_script and allows bypass of ac_supply paid to the scritpt as it would be unspendable and you would be unable to create the needed plans with no coins.
-ac_script=2ea22c8020987fad30df055db6fd922c3a57e55d76601229ed3da3b31340112e773df3d0d28103120c008203000401ccb8
-testnode=1 is not affecting magic and allows mining on a single node, we can use this to bootstrap the chain before syncing a second node to save time.
start chain and make sure to do the following steps before block 100 (set generate false/true is a good idea between steps)
./komodod -ac_name=TESTHC -ac_supply=1000000 -ac_reward=100000000000 -ac_cc=2 -ac_script=2ea22c8020987fad30df055db6fd922c3a57e55d76601229ed3da3b31340112e773df3d0d28103120c008203000401ccb8 -ac_founders=150 -ac_blocktime=20 -ac_nk=96,5 -testnode=1
create rewards plan and fund it with all or a % of the premine. Must be some amount. eg.
./komodo-cli -ac_name=TESTHC rewardscreatefunding test 50000 25 0 2 500
do rewards add funding:
./komodo-cli -ac_name=TESTHC rewardsaddfunding test 47a3150150bd196bd2086cae5e0c6b01a23785a04139fa660d169121a534b38e 1000
and get the script pubkey and op_return from this tx (no need to send it)
./komodo-cli -ac_name=TESTHC decoderawtransaction 010000000204ca4c7aaae62bb8fc9412ac010e047fa8d33c3f87d2adeb3e02170642ddfe370000000049483045022100d7b9a

From the return of this you need the scriptpubkey hex of vout 0:
scriptPubKey: 2ea22c802065686d47a4049c2c845a71895a915eb84c04445896eec5dc0be40df0b31372da8103120c008203000401cc
and the scriptpubkey hex of the OP_RETURN in vout 2.
OP_RETURN: 6a2ae54174657374000000008eb334a52191160d66fa3941a08537a2016b0c5eae6c08d26b19bd500115a347
create txidopreturn for this payment:
./komodo-cli -ac_name=TESTHC paymentstxidopret '[50,"2ea22c802065686d47a4049c2c845a71895a915eb84c04445896eec5dc0be40df0b31372da8103120c008203000401cc","6a2ae54174657374000000008eb334a52191160d66fa3941a08537a2016b0c5eae6c08d26b19bd500115a347"]'
create the txidopret for the founders reward(s) pubkeys: should be able to be a few here, not sure of max number yet. These can pay anything that does not need an opreturn. allocation and scriptpubkey hex.
./komodo-cli -ac_name=TESTHC paymentstxidopret '[50,"76a9146bf5dd9f679c87a3f83ea176f82148d26653c04388ac"]'
create payments plan:
./komodo-cli -ac_name=TESTHC paymentscreate '[0,0,"61f55f2f87dad3a37d42731a8cb73b3ebea1817abfa176218162c360a8bd7145","0550014823ffa0aa99d7dd7ca5292f4dd0a1b9156eddec03412c953f095181bc"]'
gives plan txid: ee7765be874fb084c00538b1b0488e8ecb857de253f09a9ba6ea8d3579b77d33
paymentsfund:
To do this you first need to change the type of tx generated by paymentsfund RPC. in payments.cpp go to line: 639 and comment it out, then uncomment the block of code under this.
change the line 646 to line 647 with comments, and line 650/651 aswell. This enables the RPC to generate the ccvout opreturn payload you need without sending the payment on the chain. Just decode the raw hex.
./komodo-cli -ac_name=TESTHC paymentsfund '["ee7765be874fb084c00538b1b0488e8ecb857de253f09a9ba6ea8d3579b77d33",1000,1]'
get the payment fund scriptpubkey hex from vout 0: (the split it at OP_CHECKCRYPTOCONDITION or 'cc' )
2ea22c8020987fad30df055db6fd922c3a57e55d76601229ed3da3b31340112e773df3d0d28103120c008203000401cc 2a0401f00101246a22f046337db779358deaa69b9af053e27d85cb8e8e48b0b13805c084b04f87be6577ee75
put the second half into an OP_RETURN: (the remaining part of the the above scriptpubkey) eg.
./komodo-cli -ac_name=TESTHC opreturn_burn 1 2a0401f00101246a22f046337db779358deaa69b9af053e27d85cb8e8e48b0b13805c084b04f87be6577ee75
opret_burn takes any burn amount and arbitrary hex string. (RPC works, but may have bugs, likely use this for LABS too with some fixes)
this gives a raw hex. Decode it and check the OP_RETURN is right before sending.
-earlytxid=810bd62fb8353fad20267ff2050684b8829affa3edf6b366633931530791dfce
restart the chain with earlytxid param before height 100 on all nodes (if not using -testnode=1)
./komodod -ac_name=TESTHC -ac_supply=1000000 -ac_reward=100000000000 -ac_cc=2 -ac_script=2ea22c8020987fad30df055db6fd922c3a57e55d76601229ed3da3b31340112e773df3d0d28103120c008203000401ccb8 -ac_founders=150 -ac_blocktime=20 -ac_nk=96,5 -earlytxid=810bd62fb8353fad20267ff2050684b8829affa3edf6b366633931530791dfce
once the payments plan has been funded with the mined coinbase you can issue payments release when conditions of the plan are met to fund founders reward/rewards plan. eg.
./komodo-cli -ac_name=TESTHC paymentsrelease '["ee7765be874fb084c00538b1b0488e8ecb857de253f09a9ba6ea8d3579b77d33",500]'
