feat: implement DIP0026 by panleone · Pull Request #5799 · dashpay/dash

panleone · 2024-01-04T16:02:09Z

Implement DIP0026 following the official documentation https://github.com/dashpay/dips/blob/master/dip-0026.md
With this PR it is possible to create a masternode that havs up to 32 payees and it is a first step toward trustless masternode shares

What was done?

In ProTxs the field CScript scriptPayout has been changed to std::vector<PayoutShare> payoutShares; which is a vector of scripts/ rewards shares.
Serialiation and Deserialization of ProTxs has been changed accordingly
Finally I added the regtest parameters to activate DIP0026 with a soft fork

How Has This Been Tested?

I have added unit tests that test creation, consensus and payment of masternodes with more than one payee

Checklist:

I have performed a self-review of my own code
I have commented my code, particularly in hard-to-understand areas
I have added or updated relevant unit/integration/functional/e2e tests
I have made corresponding changes to the documentation
I have assigned this pull request to a milestone

I haven't reviewed this yet; but thank you for your contribution!

Expand CProRegTx and CProUpRegTx according to DIP0026 standard, change serialization and deserialization methods in order to take in account the new field, Add consensus rules specified in the DIP0026 (max 32 payees, sum of payment shares cannot be greater than 10000,...) change dmnstate in order to take in account the new field change consensus rules in such a way that masternodes will pay all the payees add multiple payees in the qt masternode table

In this way any deployment that is activated with DIP0023 will be deployed on regtest after activating spork 24

And improve dynamically_prepare_masternode in such a way to support multiple payees

e24cb23 feat(consensus): Generalize regtest ehf should be in its own separate PR imo. Thoughts @knst @PastaPastaPasta ?

Unlikely we are going to have any other EHF fork before dip0026 is merged.
But to speed up process review, merging new code and reduce conflicts (dip0026 goes for v21, not v20.x) it's reasonable to split

src/rpc/evo.cpp

src/masternode/payments.cpp

+            if (payeeReward > 0) {
+                voutMasternodePaymentsRet.emplace_back(payeeReward, payoutShare.scriptPayout);
+            }
+        }


There is a set of rules which really makes you want to keep Operator related things separated I think:

only Operator must be able to change his payout script

Operator must not be able to change anyone else's payouts

UdjinM6 · 2024-01-08T16:24:17Z

Looks very solid. Needs some cleanups and small fixes but great job overall @panleone ! 👍

A helper class has been added which has the role to wrap and correctly serialize and deserialize a vector of payoutShare.

@panleone @PastaPastaPasta @UdjinM6
I've just observed another crucial aspect. With the "mn_rr" hard fork, a portion of the masternodes' rewards will be reallocated between the masternodes directly and the platform reward (approximately 37%). The platform is responsible for managing its share of the reward and distributing it among evo nodes.

Therefore, once the mn_rr is activated (in conjunction with the platform release witch is expected before DIP0026 hard fork), we will require the platform to also support an array of payees.

Good point, then we must also implement dip0026 on platform. At the moment due to exams I don't have enough free time to do it, but since v21 is still far away it should not be a problem

ℹ️ Backport Verification - Not Applicable

This PR implements DIP0026 (masternode payout shares), which is a Dash-specific feature, not a Bitcoin backport.

Original Bitcoin commit: N/A - This is a Dash-native implementation
Reviewed commit hash: 4b5c4aaac1-verify-1753723627

Why verification was skipped:

This PR introduces new Dash functionality (DIP0026)
No corresponding Bitcoin changes to verify against
This is legitimate Dash development, not a backport

Recommendation: This PR should be reviewed through the standard Dash development process, not the backport verification system.

Note: The backport verification system only applies to PRs that port changes from Bitcoin Core to Dash Core.
