Submissions to the network now require a fee to be paid to the network (mining fee) using a special transaction with a OP_RETURN && ProposalHash in one of the outputs. This allows the network to filter spam quickly, while also allowing anyone to submit a proposal to the network.
To implement these changes we've introduced a few new commands:
mnbudget prepare PROPOSAL-NAME URL PAYMENT_COUNT BLOCK_START DASH_ADDRESS DASH_AMOUNT YES|NO|ABSTAIN [USE_IX(TRUE|FALSE)]
- To create the special transaction
mnbudget submit PROPOSAL-NAME URL PAYMENT_COUNT BLOCK_START DASH_ADDRESS DASH_AMOUNT YES|NO|ABSTAIN FEE_TX
- After the transaction is accepted by the network and has 3 confirmations, you can submit the transaction to the network here
mnbudget show
- Get the proposal hash from here
mnbudget vote PROPOSAL-HASH YES|NO|ABSTAIN
- You can now simply vote by hash using this command
-Syncing now happens in stages. Masternodes and Sporks, then Masternode winners, then proposals. Some of these require the masternode signatures, otherwise there are race conditions within the syncing process itself.
-Resigning - When a proposal is sent to the network initially it's signed by a masternode, if that masternode goes inactive the proposal becomes invalid. Resigning allows other masternodes to update proposal keep it valid with the coming and going of masternodes.
-Resigning compatibility - non masternodes will scan and flag proposals as invalid to accept updated owners.
-Invalid votes are now actively removed from the proposals when they go inactive
- Remove budgets with negative votes of more than 10% of network
- Only allow proposals into budget that have more than 10% of network support
- Faster removal of inactive masternodes
- Implemented spork for only paying new nodes after a period of time on mainnet
- protocol bump
- fixed a few issues with sporks. Spork show now shows all sporks, instead of the changed ones. IsSporkActive now supports sporks set to 0 as on.
- With nodes coming and going on the network, the network could come to different opinions about who should get paid next in line due to some nodes being flagged as failing a PoSe check. This will have to be fixed by introducing a blockchain based PoSe system, but that's out of the scope of this release. To fix the issues in the interrim, I'm removing PoSe checks for the time being.
- Masternode nLastPaid is removed and a new caching system that keeps the last 30 days of coinbase payees replaces it
- To deal with some significant attack vectors, the masternode donation feature was removed. The donation feature was added to support developement anyway, so this will be replaced by the budgeting code.
- This code should allow the network to come to consensus about who should be paid pretty effectively
- Added FindProposal and FindFinalBudget to budgeting class
- Added 2 new sporks for Proposals and Budget payment enforcement. This is outside of the decentralized code so we can turn it off if there's a problem.
- Detect budget blocks and pay correct amounts in super blocks
- All budgeting code seems to be rather stable now. Serialization/caching is working rather well.
- Fixed some ambiguous variable names within the budgeting system that were causing the file caching to not work all of the time
- Added commands for using budgets "mnbudget" and "mnfinalbudget"
- Supports 100% decentralized budget control and view-only site with json meta data object
- Removed of reference node and replaced with decentralized quorums that pick the masternodes who get paid each block.
- Made a budgeting system, where masternodes can vote on individual budgets and the data is stored perminently on each clients computer
Some tests in CheckBlockIndex require chainActive.Tip(), but when reindexing, chainActive has not been set on the first call to CheckBlockIndex.
reindex.py starts a node, mines 3 blocks, stops, and reindexes with CheckBlockIndex enabled.

This adds a -checkblockindex (defaulting to true for regtest), which occasionally
does a full consistency check for mapBlockIndex, setBlockIndexCandidates, chainActive, and
mapBlocksUnlinked.
- Ensures ports remain open and client are responsive to IX requests.
- Completely 100% decentralized. This farms out the work of checking the masternode network to the masternode network. 1% of the network is determistically selected to check another 1% of the network each block. It takes six separate checks to deactivate a node, thus making it tamper proof.
- Nodes are kept in the masternode list if they fail enough PoSe checks to deactivate. They will continue to be checked until the operator fixes them. However they will not be paid while they're failing checks.
When re-indexing, there are a few cases where garbage data may be skipped in
the block files. In these cases, the indices are correctly written to the index
db, however the pointer to the next position for writing in the current block
file is calculated by adding the sizes of the valid blocks found.
As a result, when the re-index is finished, the index db is correct for all
existing blocks, but the next block will be written to an incorrect offset,
likely overwriting existing blocks.
Rather than using the sum of all valid blocks to determine the next write
position, use the end of the last block written to the file. Don't assume that
the current block is the last one in the file, since they may be read
out-of-order.

The only time when a client sends a "getaddr" message is when he
esatblishes an Outbound connection (see ProcessMessage() in
src/main.cpp). Another bitcoin client is expected to receive a
"getaddr" message only on Inbound connection. Ignoring "gettaddr"
requests on Outbound connections can resolve potential privacy issues
(and as was said such request normally do not happen anyway).

With headers-first we can compare against the best header timestamp, rather
than using checkpoints which require code updates to maintain.

- call ProcessMessageMasternodePayments on ProcessBlock (lost after moving mnodeman functionality)
- do not process extra functionality messages (DS, IX, spork) on initial download / reindex
Normally bitcoin core does not display any network originated strings without
sanitizing or hex encoding. This wasn't done for strcommand in many places.
This could be used to play havoc with a terminal displaying the logs,
especially with printtoconsole in use.
Thanks to Evil-Knievel for reporting this issue.

- Scan IX locks on new blocks to make sure no conflicting txes are present
- Upon completion of a IX lock, check for conflicts and remove blocks if needed
This harmonizes the block fetch timeout with the existing ping timeout
and eliminates a guaranteed eventual failure from congestion collapse
for a network operating right at its limit.
It's unlikely that we wouldn't suffer other failures if we were really
anywhere near the network's limit, and a complete avoidance of congestion
collapse risk requires (I think) an exponential back-off. So this isn't
a major concern, but I think it's also useful for reducing the complexity
of understanding out timeouts.
