feat(drive)!: withdrawal limit mirrors Core's credit pool and counts withdrawals in flight by PastaPastaPasta · Pull Request #4906 · dashpay/platform

PastaPastaPasta · 2026-09-21T23:24:41Z

Issue being fixed or feature implemented

Platform must never pool an asset unlock that Core rejects on its withdrawal limit. After dashpay/dash#7639 that is also user-visible: Core's InstantSend signers lock no unlock while the mempool's pending withdrawal total exceeds Core's currentLimit, on the assumption that Platform pools under the same limit.

The PV14 rule from #4452, #4457 and #4486 (15% of the total credits Platform held a day ago, plus recorded inflows, minus reservations, all keyed by Tenderdash block time) measures its own quantities, and every place they differ from what Core enforces on is a way to sign an unlock Core will not mine (all verified against v4.2-dev and mainnet on 2026-09-21):

Units: Core's window is 576 Core blocks = 25.2 h at the observed 2.627 min/block; Platform's is 24 h of Tenderdash time. Core's is the longer one, so a 15% tranche can be counted twice at Platform's rollover.
Anchor: Platform debits at pooling and forgets 25 h later, Core debits at mining, up to 48 blocks per sign and unbounded across re-signs.
Inflows: Platform books a whole epoch of Core rewards as one inflow at the epoch boundary (~2250 DASH on mainnet, ~250 DASH/day) while Core absorbed them per block; asset locks are booked at state transition execution, arbitrarily after Core mined them (chain proof) or before (instant proof).
Base: Platform's total credits is not Core's pool balance (lower by withdrawals in flight, unpaid epoch rewards and FAILED dust; higher transiently by instant-locked unmined locks).
Caps: both were 4000 DASH, so in the regime mainnet is in (pool 36.9k DASH) there was no margin at all.

What was done?

Platform now mirrors Core's rule on Core's own numbers instead of approximating them. Core's V24 rule becomes (dashpay/dash#7712; DIP text in dashpay/dips#192): with P the pool balance after a block and D the balance 576 blocks earlier, unlocks may not leave the pool below D − max(20% × D, 2000 DASH), and Core exposes P, D and its own currentLimit through the new getcreditpoolinfo RPC.

calculate_current_withdrawal_limit v1 (in place, PV14 is unreleased on mainnet) reads getcreditpoolinfo at the block's core_chain_locked_height (every validator sees the same chain locked block, so the values are deterministic) and keeps

min( max(15% × D, 500 DASH) − (D − P),  currentlimit ) − in_flight

available. Same shape as Core's rule with a smaller share and no absolute cap on either side: Platform is at or below three quarters of what Core admits in every regime (floor 2000 vs at most 1500, then 20% vs 15%), and that gap absorbs what the pool moves between the chain locked height and the tip that mines the unlock. The rule is net on both chains because both read the same balances: a deposit raises P and is withdrawable again inside the window without any inflow bookkeeping.

In flight replaces the 25-hour reservation. A pooled withdrawal is recorded in the withdrawal sum tree under its transaction index (add_enqueue_untied_withdrawal_transaction_operations v1, ReserveInFlightWithdrawals) and released only when Core reports it mined at or below the chain locked height, or when it fails for good (remove_broadcasted_withdrawal_transactions_after_completion_operations v1, ReleaseInFlightWithdrawals, reached from update_broadcasted_withdrawal_statuses and rebroadcast_expired_withdrawal_documents v2). Platform therefore never has more outstanding than Core admits, however long mining takes.

Upgrade path (PV13 → PV14): transition_to_version_14 empties the withdrawal sum tree of the time-keyed reservations of PV13, which no release could ever match, and re-records every withdrawal in flight (pooled, broadcast or expired documents) under its transaction index, so an in-place upgrade neither loses track of outstanding unlocks nor carries dead reservations forever. Covered by a transition test with a day-old reservation and three documents in different statuses.

Removed: the total-credits history tree and the credit-inflows sum tree (keys 4 and 5), record_total_credits_history_for_withdrawals, record_credit_inflows_for_withdrawals, fetch_total_credits_in_platform_a_day_ago, cleanup_expired_locks_of_withdrawal_amounts v1 (the slot is now optional and None from PV14: nothing expires by time), withdrawal constants v3 and DAY_AND_A_HOUR_IN_MS (kept privately by the pre-v14 enqueue). Pre-v14 code paths are untouched; the v14 upgrade hook no longer creates the two trees.

Constants: daily_withdrawal_limit_percent stays 15; max_daily_withdrawal_amount 4000 → None (daily_withdrawal_limit v2 now treats the cap as optional; Core's rule has none either); max_withdrawal_amount 500 stays the floor.

Core RPC client: CoreRPCLike::get_credit_pool_info(height) and CreditPoolInfo; pool_withdrawals_into_transactions_queue v2 fetches it, checks the reported height, and pools against it.

Docs: v14.rs, system_limits/{mod,v4}.rs, the version tables, the GroveDB structure description and book/.

How Has This Been Tested?

cargo test -p dpp --lib daily_withdrawal_limit
cargo test -p platform-version --lib
UPDATE_GROVEDB_STRUCTURE=1 cargo test -p drive --features server --lib -- withdrawals structure (regenerates grovedb-structure.json)
cargo test -p drive-abci --lib -- withdrawals protocol_upgrade rpc::core finalize_block
RUST_MIN_STACK=4194304 cargo test -p drive-abci --test strategy_tests -- withdrawal_tests comprehensive
cargo clippy -p drive -p drive-abci -p dpp -p platform-version --features drive/server --all-targets -- -D warnings

The rewritten strategy test scripts Core's answers: 80 withdrawals of 50 DASH against a 10,100 DASH pool pool 1,515 DASH and then hold, unchanged over 50 blocks, until Core reports them mined; the window then rolls to the new balance; Core's own limit binds when it is the smaller number; everything completes with nothing in flight.

Breaking Changes

PV14 state changes in place (the table comment in system_limits/v4.rs says PV14 stays editable until it is live on mainnet): the withdrawal sum tree's keys change meaning, and trees 4 and 5 are no longer created. Chains that upgrade from PV13 with this code are migrated by the transition hook. Any network that has already activated PV14 with the previous 4.2 pre-releases must be reset: its state holds the two dropped trees and time-keyed reservations, and a node replaying from genesis with this code would compute a different app hash. If a live PV14 network cannot be reset, this has to ship as PV15 with the same migration in a v15 hook instead. Decision owed to the Platform team.
Platform 4.2 requires a Core that serves getcreditpoolinfo (Core v24 with feat(consensus): relative net asset-unlock limit for v24 and getcreditpoolinfo dash#7712). The call happens inside block processing whenever withdrawals are queued; a node whose Core lacks the RPC fails those blocks and stops, the same way a Core that cannot answer getassetunlockstatuses does. Until Core's V24 activates, the RPC reports v22's flat 2000 DASH per block as Core's limit, which bounds Platform's in-flight total to 2000 DASH (stricter, never looser).
daily_withdrawal_limit v2 now takes Core's window-start balance as its reference and has no absolute cap.

📝 Walkthrough

Walkthrough

Protocol version 14 now derives withdrawal limits from Core’s credit pool. Platform removes prior credit-history and inflow trees, records withdrawals by transaction index while in flight, and adds Core RPC support and migration logic.

Changes

Withdrawal-limit protocol configuration

Layer / File(s)	Summary
Protocol configuration and documentation `book/src/versioning/`, `packages/rs-dpp/src/withdrawal/`, `packages/rs-platform-version/src/version/*`	Protocol version 14 uses Core credit-pool data, disables expiration cleanup, removes credit-history fields, and removes the fixed absolute cap.
Core-based limit calculation and storage model `packages/rs-drive/src/drive/identity/withdrawals/*`, `packages/rs-drive/grovedb-structure.json`	Limit calculation consumes Core pool snapshots and indexed in-flight withdrawals. Total-credit history and credit-inflow storage APIs and structures are removed.
Core RPC and in-flight withdrawal operations `packages/rs-drive-abci/src/rpc/core.rs`, `packages/rs-drive-abci/src/execution/platform_events/withdrawals/`, `packages/rs-drive/src/drive/identity/withdrawals/transaction/`, `packages/rs-drive/src/util/batch/drive_op_batch/withdrawals.rs`	Core pool RPC data flows into withdrawal pooling. Queue operations reserve per-transaction amounts and release them after completion.
Protocol transition and expiration lifecycle `packages/rs-drive-abci/src/execution/platform_events/protocol_upgrade/`, `packages/rs-drive-abci/src/execution/engine/`, `packages/rs-drive-abci/src/execution/platform_events/withdrawals/cleanup_expired_locks_of_withdrawal_amounts/*`	The version 14 transition rebuilds the sum tree from pooled, broadcast, and expired withdrawals. Time-based cleanup and old recording paths are removed.
Validation, fixtures, and terminology updates `packages/rs-drive-abci/tests/`, `packages/rs-drive-abci/src/execution/`	Tests, mocks, comments, and credit-mint terminology reflect Core pool data and in-flight withdrawal accounting.

…withdrawals in flight Platform reads Core's credit pool at the chain locked height (new getcreditpoolinfo RPC) and keeps at most min(max(15% of the balance one window ago, one maximal withdrawal) - the window's drop, Core's own limit) pooled and not yet mined. Pooled withdrawals count under their transaction index until Core reports them mined or they fail; the time-keyed reservations, the total credits history and the credit inflows trees are gone, and the v14 transition replaces the old reservations with the withdrawals in flight. Core's v24 rule (dashpay/dash#7712) is the same shape with 20% and a 2000 Dash floor, so an unlock Platform pools is one Core accepts. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Closing: after discussion with the Platform maintainers the direction changed. Platform keeps its current PV14 rule (15% of the total credits a day ago, time-keyed) with no changes from our side; the Platform team will investigate the edge cases, and the pair will be tested to breaking on regtest/testnet. Core's side (dashpay/dash#7712) is being simplified to a plain net 20% of the credit pool balance per 576 blocks. The branch stays for reference.
