770 | // exported transactions to the reserve chain are optional fee-generating steps that would be easy to do when running multiple daemons. | |
771 | // The types of transactions miners/stakers may facilitate or create for fees are as follows: | |
772 | // | |
773 | // 1. Earned notarization of Verus chain - spends the notarization instant out. must be present and spend the notarization output if there is a notarization output | |
774 | // | |
775 | // 2. Imported transactions from the export thread for this PBaaS chain on the Verus blockchain - imported transactions must spend the import utxo | |
776 | // thread, represent the export from the alternate chain which spends the export output from the prior import transaction, carry a notary proof, and | |
777 | // include outputs that map to each of its inputs on the source chain. Outputs can include unconverted reserve outputs only on fractional | |
778 | // reserve chains, pre-converted outputs for any chain with launch conversion, and post launch outputs to be converted on fractional reserve | |
779 | // chains. Each are handled in the following way: | |
780 | // a. Unconverted outputs are left as outputs to the intended destination of Verus reserve token and do not pass through the coinbase | |
781 | // b. Pre-converted outputs require that the import transaction spend the last pre-conversion output starting at block 1 as the source for | |
782 | // pre-converted currency. | |
783 | // | |
784 | // 3. Zero or more aggregated exports that combine individual cross-chain transactions and reserve transfer outputs for export to the Verus chain. | |
785 | // | |
786 | // 4. Conversion distribution transactions for all native and reserve currency conversions, including reserve transfer outputs without conversion as | |
787 | // a second step for reserve transfers that have conversion included. Any remaining pre-converted reserve must always remain in a change output | |
