payments airdrop:
- extra RPC to merge all payments inputs to a single utxo, this must be called first and be confirmed before payments release,
or tx will be too big, we can check add payments inputs is only 1 input, at RPC and in validation very early on.
- do getsnapshot2 every 1440 blocks and save the result into some global sorted vector or DB?
-this allows any address balance to be calculated by only iterating each 1439 blocks maximum.
- calculate scriptpubkey to pay from each address, set allocations from balance of each address. allocation = balance?
payments airdrop paying a token: ( maybe this is more reasonable speed wise? )
- tokenid, top number of tokens to pay, list of pubkeys to exclude as optional param
- add vector of tokenids to getsnapshot2 - then sort each tokenid by balance.
put the pubkey to pay to as scriptpubkey in the saved vector.
0) txidopret <- allocation, scriptPubKey, opret
1) create <- locked_blocks, minrelease, list of txidopret
