[frame] `#[pallet::composite_enum]` improved variant count handling + removed `pallet_balances`'s `MaxHolds` config (#2657) I started this investigation/issue based on @liamaharon question [here](https://github.com/paritytech/polkadot-sdk/pull/1801#discussion_r1410452499). ## Problem The `pallet_balances` integrity test should correctly detect that the runtime has correct distinct `HoldReasons` variant count. I assume the same situation exists for RuntimeFreezeReason. It is not a critical problem, if we set `MaxHolds` with a sufficiently large value, everything should be ok. However, in this case, the integrity_test check becomes less useful. **Situation for "any" runtime:** - `HoldReason` enums from different pallets: ```rust /// from pallet_nis #[pallet::composite_enum] pub enum HoldReason { NftReceipt, } /// from pallet_preimage #[pallet::composite_enum] pub enum HoldReason { Preimage, } // from pallet_state-trie-migration #[pallet::composite_enum] pub enum HoldReason { SlashForContinueMigrate, SlashForMigrateCustomTop, SlashForMigrateCustomChild, } ``` - generated `RuntimeHoldReason` enum looks like: ```rust pub enum RuntimeHoldReason { #[codec(index = 32u8)] Preimage(pallet_preimage::HoldReason), #[codec(index = 38u8)] Nis(pallet_nis::HoldReason), #[codec(index = 42u8)] StateTrieMigration(pallet_state_trie_migration::HoldReason), } ``` - composite enum `RuntimeHoldReason` variant count is detected as `3` - we set `type MaxHolds = ConstU32<3>` - `pallet_balances::integrity_test` is ok with `3`(at least 3) However, the real problem can occur in a live runtime where some functionality might stop working. This is due to a total of 5 distinct hold reasons (for pallets with multi-instance support, it is even more), and not all of them can be used because of an incorrect `MaxHolds`, which is deemed acceptable according to the `integrity_test`: ``` // pseudo-code - if we try to call all of these: T::Currency::hold(&pallet_nis::HoldReason::NftReceipt.into(), &nft_owner, deposit)?; T::Currency::hold(&pallet_preimage::HoldReason::Preimage.into(), &nft_owner, deposit)?; T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForContinueMigrate.into(), &nft_owner, deposit)?; // With `type MaxHolds = ConstU32<3>` these two will fail T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForMigrateCustomTop.into(), &nft_owner, deposit)?; T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForMigrateCustomChild.into(), &nft_owner, deposit)?; ``` ## Solutions A macro `#[pallet::*]` expansion is extended of `VariantCount` implementation for the `#[pallet::composite_enum]` enum type. This expansion generates the `VariantCount` implementation for pallets' `HoldReason`, `FreezeReason`, `LockId`, and `SlashReason`. Enum variants must be plain enum values without fields to ensure a deterministic count. The composite runtime enum, `RuntimeHoldReason` and `RuntimeFreezeReason`, now sets `VariantCount::VARIANT_COUNT` as the sum of pallets' enum `VariantCount::VARIANT_COUNT`: ```rust #[frame_support::pallet(dev_mode)] mod module_single_instance { #[pallet::composite_enum] pub enum HoldReason { ModuleSingleInstanceReason1, ModuleSingleInstanceReason2, } ... } #[frame_support::pallet(dev_mode)] mod module_multi_instance { #[pallet::composite_enum] pub enum HoldReason<I: 'static = ()> { ModuleMultiInstanceReason1, ModuleMultiInstanceReason2, ModuleMultiInstanceReason3, } ... } impl self::sp_api_hidden_includes_construct_runtime::hidden_include::traits::VariantCount for RuntimeHoldReason { const VARIANT_COUNT: u32 = 0 + module_single_instance::HoldReason::VARIANT_COUNT + module_multi_instance::HoldReason::<module_multi_instance::Instance1>::VARIANT_COUNT + module_multi_instance::HoldReason::<module_multi_instance::Instance2>::VARIANT_COUNT + module_multi_instance::HoldReason::<module_multi_instance::Instance3>::VARIANT_COUNT; } ``` In addition, `MaxHolds` is removed (as suggested [here](https://github.com/paritytech/polkadot-sdk/pull/2657#discussion_r1443324573)) from `pallet_balances`, and its `Holds` are now bounded to `RuntimeHoldReason::VARIANT_COUNT`. Therefore, there is no need to let the runtime specify `MaxHolds`. ## For reviewers Relevant changes can be found here: - `substrate/frame/support/procedural/src/lib.rs` - `substrate/frame/support/procedural/src/pallet/parse/composite.rs` - `substrate/frame/support/procedural/src/pallet/expand/composite.rs` - `substrate/frame/support/procedural/src/construct_runtime/expand/composite_helper.rs` - `substrate/frame/support/procedural/src/construct_runtime/expand/hold_reason.rs` - `substrate/frame/support/procedural/src/construct_runtime/expand/freeze_reason.rs` - `substrate/frame/support/src/traits/misc.rs` And the rest of the files is just about removed `MaxHolds` from `pallet_balances` ## Next steps Do the same for `MaxFreezes` https://github.com/paritytech/polkadot-sdk/issues/2997. --------- Co-authored-by: command-bot <> Co-authored-by:

This PR allows _username authorities_ to issue unique usernames that correspond with an account. It also provides two-way lookup, that is from `AccountId` to a single, "primary" `Username` (alongside `Registration`) and multiple unique `Username`s to an `AccountId`. Key features: - Username Authorities added (and removed) via privileged origin. - Authorities have a `suffix` and an `allocation`. They can grant up to `allocation` usernames. Their `suffix` will be appended to the usernames that they issue. A suffix may be up to 7 characters long. - Users can ask an authority to grant them a username. This will take the form `myusername.suffix`. The entire name (including suffix) must be less than or equal to 32 alphanumeric characters. - Users can approve a username for themselves in one of two ways (that is, authorities cannot grant them arbitrarily): - Pre-sign the entire username (including suffix) with a secret key that corresponds to their `AccountId` (for keyed accounts, obviously); or - Accept the username after it has been granted by an authority (it will be queued until accepted) (for non-keyed accounts like pure proxies or multisigs). - The system does not require any funds or deposits. Users without an identity will be given a default one (presumably all fields set to `None`). If they update this info, they will need to place the normal storage deposit. - If a user does not have any username, their first one will be set as `Primary`, and their `AccountId` will map to that one. If they get subsequent usernames, they can choose which one to be their primary via `set_primary_username`. - There are some state cleanup functions to remove expired usernames that have not been accepted and dangling usernames whose owners have called `clear_identity`.

closes https://github.com/paritytech/polkadot-sdk/issues/1842 Decoupling Pallet from the Concept of Native Currency Currently, the pallet is intrinsically linked with the concept of native currency, requiring users to provide implementations of the `fungible::*` and `fungibles::*` traits to interact with native and non native assets. This incapsulates some non-related to the pallet complexity and makes it less adaptable in contexts where the native currency concept is absent. With this PR, the dependence on `fungible::*` for liquidity-supplying assets has been removed. Instead, the native and non-native currencies' handling is now overseen by a single type that implements the `fungibles::*` traits. To simplify this integration, types have been introduced to facilitate the creation of a union between `fungible::*` and `fungibles::*` implementations, producing a unified `fungibles::*` type. One of the reasons driving these changes is the ambition to create a more user-friendly API for the `SwapCredit` implementation. Given that it interacts with two distinct credit types from `fungible` and `fungibles`, a unified type was introduced. Clients now manage potential conversion failures for those credit types. In certain contexts, it's vital to guarantee that operations are fail-safe, like in this impl - [PR](https://github.com/paritytech/polkadot-sdk/pull/1845), place in [code](https://github.com/paritytech/polkadot-sdk/blob/20b85a5f /cumulus/primitives/utility/src/lib.rs#L429). Additional Updates: - abstracted the pool ID and its account derivation logic via trait bounds, along with common implementation offerings; - removed `inc_providers` on a pool creation for the pool account; - benchmarks: -- swap complexity is N, not const; -- removed `From<u128> + Into<u128>` bound from `T::Balance`; -- removed swap/liquidity/.. amount constants, resolve them dynamically based on pallet configuration; -- migrated to v2 API; - `OnUnbalanced` handler for the pool creation fee, replacing direct transfers to a specified account ID; - renamed `MultiAssetId` to `AssetKind` aligning with naming across frame crates; related PRs: - (depends) https://github.com/paritytech/polkadot-sdk/pull/1677 - (caused) https://github.com/paritytech/polkadot-sdk/pull/2033 - (caused) https://github.com/paritytech/polkadot-sdk/pull/1876 --------- Co-authored-by:

Introduces a swap implementation that allows the exchange of a credit (aka Negative Imbalance) of one asset for a credit of another asset. This is particularly useful when a credit swap is required but may not have sufficient value to meet the ED constraint, hence cannot be deposited to temp account before. An example use case is when XCM fees are paid using an asset held in the XCM executor registry and has to be swapped for native currency. Additional Updates: - encapsulates the existing `Swap` trait impl within a transactional context, since partial storage mutation is possible when an error occurs; - supplied `Currency` and `Assets` impls must be implemented over the same `Balance` type, the `AssetBalance` generic type is dropped. This helps to avoid numerous type conversion and overflow cases. If those types are different it should be handled outside of the pallet; - `Box` asset kind on a pallet level, unbox on a runtime level - here [why](https://substrate.stackexchange.com/questions/10039/boxed-argument-of-a-dispatchable/10103#10103); - `path` uses `Vec` now, instead of `BoundedVec` since it is never used in PoV; - removes the `Transfer` event due to it's redundancy with the events emitted by `fungible/s` implementations; - modifies the `SwapExecuted` event type; related issue: - https://github.com/paritytech/polkadot-sdk/issues/105 related PRs: - (required for) https://github.com/paritytech/polkadot-sdk/pull/1845 - (caused) https://github.com/paritytech/polkadot-sdk/pull/1717 // DONE make the pallet work only with `fungibles` trait and make it free from the concept of a `native` asset - https://github.com/paritytech/polkadot-sdk/issues/1842 --------- Co-authored-by: -

closes https://github.com/paritytech-secops/srlabs_findings/issues/78. Removes `BetterUnsignedThreshold` from pallet EPM. This will essentially mean any solution submitted by the validator that is strictly better than the current queued solution would be accepted. The reason for having these thresholds is to limit number of solutions submitted on-chain. However for unsigned submissions, the number of solutions that could be submitted on average is limited even without thresholding (calculation shown in the corresponding issue).

Fixes https://github.com/paritytech/polkadot-sdk/issues/1725 This PR adds the following changes: 1. An attribute `pallet::feeless_if` that can be optionally attached to a call like so: ```rust #[pallet::feeless_if(|_origin: &OriginFor<T>, something: &u32| -> bool { *something == 0 })] pub fn do_something(origin: OriginFor<T>, something: u32) -> DispatchResult { .... } ``` The closure passed accepts references to arguments as specified in the call fn. It returns a boolean that denotes the conditions required for this call to be "feeless". 2. A signed extension `SkipCheckIfFeeless<T: SignedExtension>` that wraps a transaction payment processor such as `pallet_transaction_payment::ChargeTransactionPayment`. It checks for all calls annotated with `pallet::feeless_if` to see if the conditions are met. If so, the wrapped signed extension is not called, essentially making the call feeless. In order to use this, you can simply replace your existing signed extension that manages transaction payment like so: ```diff - pallet_transaction_payment::ChargeTransactionPayment<Runtime>, + pallet_skip_feeless_payment::SkipCheckIfFeeless< + Runtime, + pallet_transaction_payment::ChargeTransactionPayment<Runtime>, + >, ``` ### Todo - [x] Tests - [x] Docs - [x] Prdoc --------- Co-authored-by: Nikhil Gupta <> Co-authored-by:

helps https://github.com/paritytech/polkadot-sdk/issues/439. closes https://github.com/paritytech/polkadot-sdk/issues/473. PR link in the older substrate repository: https://github.com/paritytech/substrate/pull/13498. # Context Rewards payout is processed today in a single block and limited to `MaxNominatorRewardedPerValidator`. This number is currently 512 on both Kusama and Polkadot. This PR tries to scale the nominators payout to an unlimited count in a multi-block fashion. Exposures are stored in pages, with each page capped to a certain number (`MaxExposurePageSize`). Starting out, this number would be the same as `MaxNominatorRewardedPerValidator`, but eventually, this number can be lowered through new runtime upgrades to limit the rewardeable nominators per dispatched call instruction. The changes in the PR are backward compatible. ## How payouts would work like after this change Staking exposes two calls, 1) the existing `payout_stakers` and 2) `payout_stakers_by_page`. ### payout_stakers This remains backward compatible with no signature change. If for a given era a validator has multiple pages, they can call `payout_stakers` multiple times. The pages are executed in an ascending sequence and the runtime takes care of preventing double claims. ### payout_stakers_by_page Very similar to `payout_stakers` but also accepts an extra param `page_index`. An account can choose to payout rewards only for an explicitly passed `page_index`. **Lets look at an example scenario** Given an active validator on Kusama had 1100 nominators, `MaxExposurePageSize` set to 512 for Era e. In order to pay out rewards to all nominators, the caller would need to call `payout_stakers` 3 times. - `payout_stakers(origin, stash, e)` => will pay the first 512 nominators. - `payout_stakers(origin, stash, e)` => will pay the second set of 512 nominators. - `payout_stakers(origin, stash, e)` => will pay the last set of 76 nominators. ... - `payout_stakers(origin, stash, e)` => calling it the 4th time would return an error `InvalidPage`. The above calls can also be replaced by `payout_stakers_by_page` and passing a `page_index` explicitly. ## Commission note Validator commission is paid out in chunks across all the pages where each commission chunk is proportional to the total stake of the current page. This implies higher the total stake of a page, higher will be the commission. If all the pages of a validator's single era are paid out, the sum of commission paid to the validator across all pages should be equal to what the commission would have been if we had a non-paged exposure. ### Migration Note Strictly speaking, we did not need to bump our storage version since there is no migration of storage in this PR. But it is still useful to mark a storage upgrade for the following reasons: - New storage items are introduced in this PR while some older storage items are deprecated. - For the next `HistoryDepth` eras, the exposure would be incrementally migrated to its corresponding paged storage item. - Runtimes using staking pallet would strictly need to wait at least `HistoryDepth` eras with current upgraded version (14) for the migration to complete. At some era `E` such that `E > era_at_which_V14_gets_into_effect + HistoryDepth`, we will upgrade to version X which will remove the deprecated storage items. In other words, it is a strict requirement that E<sub>x</sub> - E<sub>14</sub> > `HistoryDepth`, where E<sub>x</sub> = Era at which deprecated storages are removed from runtime, E<sub>14</sub> = Era at which runtime is upgraded to version 14. - For Polkadot and Kusama, there is a [tracker ticket](https://github.com/paritytech/polkadot-sdk/issues/433) to clean up the deprecated storage items. ### Storage Changes #### Added - ErasStakersOverview - ClaimedRewards - ErasStakersPaged #### Deprecated The following can be cleaned up after 84 eras which is tracked [here](https://github.com/paritytech/polkadot-sdk/issues/433). - ErasStakers. - ErasStakersClipped. - StakingLedger.claimed_rewards, renamed to StakingLedger.legacy_claimed_rewards. ### Config Changes - Renamed MaxNominatorRewardedPerValidator to MaxExposurePageSize. ### TODO - [x] Tracker ticket for cleaning up the old code after 84 eras. - [x] Add companion. - [x] Redo benchmarks before merge. - [x] Add Changelog for pallet_staking. - [x] Pallet should be configurable to enable/disable paged rewards. - [x] Commission payouts are distributed across pages. - [x] Review documentation thoroughly. - [x] Rename `MaxNominatorRewardedPerValidator` -> `MaxExposurePageSize`. - [x] NMap for `ErasStakersPaged`. - [x] Deprecate ErasStakers. - [x] Integrity tests. ### Followup issues [Runtime api for deprecated ErasStakers storage item](https://github.com/paritytech/polkadot-sdk/issues/426) --------- Co-authored-by:

# Description The `trigger_defensive` call has been added to the `root-testing` pallet. The idea is to have this pallet running on `Rococo/Westend` and use it to verify if the runtime monitoring works end-to-end. To accomplish this, `trigger_defensive` dispatches an event when it is called. Closes #1953 # Checklist - [x] My PR includes a detailed description as outlined in the "Description" section above - [ ] My PR follows the [labeling requirements](CONTRIBUTING.md#Process) of this project (at minimum one label for `T` required) - [ ] I have made corresponding changes to the documentation (if applicable) - [ ] I have added tests that prove my fix is effective or that my feature works (if applicable) You can remove the "Checklist" section once all have been checked.

# Description - What does this PR do? While working with `pallet_nfts` through `nonfungibles_v2` traits `Inspect, Mutate`, I found out that once you have set the collection attribute with `<Nfts as Mutate>::set_collection_attribute()`, it's not possible to read it with `<Nfts as Inspect>::collection_attribute()` since they use different `namespace` values. When setting the attribute, `AttributeNamespace::Pallet` is used, while `AttributeNamespace::CollectionOwner` is used when reading. more context: https://github.com/freeverseio/laos/issues/7#issuecomment-1766137370 This PR makes `item` an optional parameter in `Inspect::system_attribute()`, to be able to read collection attributes. - Why are these changes needed? To be able to read collection level attributes when reading attributes of the collection. It will be possible to read collection attributes by passing `None` for `item` - How were these changes implemented and what do they affect? `NftsApi` is also affected and `NftsApi::system_attribute()` now accepts optional `item` parameter. ## Breaking change Because of the change in the `NftsApi::system_attribute()` method's `item` param, parachains who integrated the `NftsApi` need to update their API code and frontend integrations accordingly. AssetHubs are unaffected since the NftsApi wasn't released on those parachains yet.

Fixes #179 # Description This PR makes the structure containing identity information used in `pallet-identity` generic through the pallet `Config`. Additionally, the old structure is now available in a separate module called `simple` (pending rename) and is compatible with the new interface. Another change in this PR is that while the `additional` field in `IdentityInfo` stays for backwards compatibility reasons, the associated costs are stil present in the pallet through the `additional` function in the `IdentityInformationProvider` interface. This function is marked as deprecated as it is only a temporary solution to the backwards compatibility problem we had. In short, we could have removed the additional fields in the struct and done a migration, but we chose to wait and do it off-chain through the genesis of the system parachain. After we move the identity pallet to the parachain, additional fields will be migrated into the existing fields and the `additional` key-value store will be removed. Until that happens, this interface will provide the necessary information to properly account for the associated costs. Additionally, this PR fixes an unrelated issue; the `IdentityField` enum used to represent the fields as bitflags couldn't store more than 8 fields, even though it was marked as `#[repr(u64)]`. This was because of the `derive` implementation of `TypeInfo`, which assumed `u8` semantics. The custom implementation of this trait in https://github.com/paritytech/polkadot-sdk/commit/0105cc03 fixes the issue. --------- Signed-off-by:

closes https://github.com/paritytech/polkadot-sdk/issues/1882 ## Breaking Changes This PR introduces a new item to `pallet_balances::Config`: ```diff trait Config { ++ type RuntimeFreezeReasons; } ``` This value is only used to check it against `type MaxFreeze`. A similar check has been added for `MaxHolds` against `RuntimeHoldReasons`, which is already given to `pallet_balances`. In all contexts, you should pass the real `RuntimeFreezeReasons` generated by `construct_runtime` to `type RuntimeFreezeReasons`. Passing `()` would also work, but it would imply that the runtime uses no freezes at all. --------- Signed-off-by:

See #1345, <https://github.com/paritytech/substrate/pull/14207>. This adds all the necessary mixnet components, and puts them together in the "kitchen-sink" node/runtime. The components added are: - A pallet (`frame/mixnet`). This is responsible for determining the current mixnet session and phase, and the mixnodes to use in each session. It provides a function that validators can call to register a mixnode for the next session. The logic of this pallet is very similar to that of the `im-online` pallet. - A service (`client/mixnet`). This implements the core mixnet logic, building on the `mixnet` crate. The service communicates with other nodes using notifications sent over the "mixnet" protocol. - An RPC interface. This currently only supports sending transactions over the mixnet. --------- Co-authored-by:

### Summary This PR introduces new dispatchables to the treasury pallet, allowing spends of various asset types. The enhanced features of the treasury pallet, in conjunction with the asset-rate pallet, are set up and enabled for Westend and Rococo. ### Westend and Rococo runtimes. Polkadot/Kusams/Rococo Treasury can accept proposals for `spends` of various asset kinds by specifying the asset's location and ID. #### Treasury Instance New Dispatchables: - `spend(AssetKind, AssetBalance, Beneficiary, Option<ValidFrom>)` - propose and approve a spend; - `payout(SpendIndex)` - payout an approved spend or retry a failed payout - `check_payment(SpendIndex)` - check the status of a payout; - `void_spend(SpendIndex)` - void previously approved spend; > existing spend dispatchable renamed to spend_local in this context, the `AssetKind` parameter contains the asset's location and it's corresponding `asset_id`, for example: `USDT` on `AssetHub`, ``` rust location = MultiLocation(0, X1(Parachain(1000))) asset_id = MultiLocation(0, X2(PalletInstance(50), GeneralIndex(1984))) ``` the `Beneficiary` parameter is a `MultiLocation` in the context of the asset's location, for example ``` rust // the Fellowship salary pallet's location / account FellowshipSalaryPallet = MultiLocation(1, X2(Parachain(1001), PalletInstance(64))) // or custom `AccountId` Alice = MultiLocation(0, AccountId32(network: None, id: [1,...])) ``` the `AssetBalance` represents the amount of the `AssetKind` to be transferred to the `Beneficiary`. For permission checks, the asset amount is converted to the native amount and compared against the maximum spendable amount determined by the commanding spend origin. the `spend` dispatchable allows for batching spends with different `ValidFrom` arguments, enabling milestone-based spending. If the expectations tied to an approved spend are not met, it is possible to void the spend later using the `void_spend` dispatchable. Asset Rate Pallet provides the conversion rate from the `AssetKind` to the native balance. #### Asset Rate Instance Dispatchables: - `create(AssetKind, Rate)` - initialize a conversion rate to the native balance for the given asset - `update(AssetKind, Rate)` - update the conversion rate to the native balance for the given asset - `remove(AssetKind)` - remove an existing conversion rate to the native balance for the given asset the pallet's dispatchables can be executed by the Root or Treasurer origins. ### Treasury Pallet Treasury Pallet can accept proposals for `spends` of various asset kinds and pay them out through the implementation of the `Pay` trait. New Dispatchables: - `spend(Config::AssetKind, AssetBalance, Config::Beneficiary, Option<ValidFrom>)` - propose and approve a spend; - `payout(SpendIndex)` - payout an approved spend or retry a failed payout; - `check_payment(SpendIndex)` - check the status of a payout; - `void_spend(SpendIndex)` - void previously approved spend; > existing spend dispatchable renamed to spend_local The parameters' types of the `spend` dispatchable exposed via the pallet's `Config` and allows to propose and accept a spend of a certain amount. An approved spend can be claimed via the `payout` within the `Config::SpendPeriod`. Clients provide an implementation of the `Pay` trait which can pay an asset of the `AssetKind` to the `Beneficiary` in `AssetBalance` units. The implementation of the Pay trait might not have an immediate final payment status, for example if implemented over `XCM` and the actual transfer happens on a remote chain. The `check_status` dispatchable can be executed to update the spend's payment state and retry the `payout` if the payment has failed. --------- Co-authored-by:

closes https://github.com/paritytech/polkadot-sdk/issues/158. partially addresses https://github.com/paritytech/polkadot-sdk/issues/226. Instead of fragile calculation of current balance by looking at `free balance - ED`, Nomination Pool now freezes ED in the pool reward account to restrict an account from going below minimum balance. This also has a nice side effect that if ED changes, we know how much is the imbalance in ED frozen in the pool and the current required ED. A pool operator can diligently top up the pool with the deficit in ED or vice versa, withdraw the excess they transferred to the pool. ## Notable changes - New call `adjust_pool_deposit`: Allows to top up the deficit or withdraw the excess deposited funds to the pool. - Uses Fungible trait (instead of Currency trait). Since NP was not doing any locking/reserving previously, no migration is needed for this. - One time migration of freezing ED from each of the existing pools (not very PoV friendly but fine for relay chain).

**Note**: This is a lift-and-shift PR from the old substrate and polkadot repos, both PRs have been reviewed and audited (https://github.com/paritytech/substrate/pull/13983, https://github.com/paritytech/polkadot/pull/7140) --- This PR implements a generic `BaseDeposit` calculation for signed submissions, based on the size of the submission queue. It adds a new associated type to EPM's config, `type SignedDepositBase`, that implements `Convert<usize, BalanceOf<T>>`, which is used to calculate the base deposit for signed submissions based on the size of the signed submissions queue. `struct GeometricDepositBase<Balance, Fixed, Inc>` implements the convert trait so that the deposit value increases as a geometric progression. The deposit base is calculated by `deposit_base = fixed_deposit_base * (1 + increase_factor)^n`, where `n` is the term of the progression (i.e. the number of signed submissions in the queue). `Fixed` and `Inc` generic params are getters for `Balance` and `IncreaseFactor` to compute the geometric progression. If `IncreaseFactor = 0`, then the signed deposit is constant and equal to `Fixed` regardless of the size of the queue. ### Runtime configs In Kusama, the progression with 10% increase without changing the current signed fixed deposit is: (term == size of the queue) Term 1: `1,333,333,332,000` Term 2: `1,333,333,332,000 * 1.10 = 1,466,666,665,200` Term 3: `1,333,333,332,000 * 1.10^2 = 1,613,333,331,200` Term 4: `1,333,333,332,000 * 1.10^3 = 1,774,666,664,320` Term 5: `1,333,333,332,000 * 1.10^4 = 1,952,133,330,752` Term 6: `1,333,333,332,000 * 1.10^5 = 2,147,346,663,827.20` Term 7: `1,333,333,332,000 * 1.10^6 = 2,362,081,330,210.92` Term 8: `1,333,333,332,000 * 1.10^7 = 2,598,289,463,231.01` Term 9: `1,333,333,332,000 * 1.10^8 = 2,858,118,409,554.11` Term 10: `1,333,333,332,000 * 1.10^9 = 3,143,930,250,509.52` Westend: Term 1: `2,000,000,000,000` Term 2: `2,000,000,000,000 * 1.10 = 2,200,000,000,000` Term 3: `2,000,000,000,000 * 1.10^2 = 2,420,000,000,000` Term 4: `2,000,000,000,000 * 1.10^3 = 2,662,000,000,000` Term 5: `2,000,000,000,000 * 1.10^4 = 2,928,200,000,000` Term 6: `2,000,000,000,000 * 1.10^5 = 3,221,020,000,000` Term 7: `2,000,000,000,000 * 1.10^6 = 3,543,122,000,000` Term 8: `2,000,000,000,000 * 1.10^7 = 3,897,434,200,000` Term 9: `2,000,000,000,000 * 1.10^8 = 4,287,177,620,000` Term 10: `2,000,000,000,000 * 1.10^9 = 4,715,895,382,000` and in Polkadot, the deposit increase is disabled in the current state of the PR, as the increase factor is 0% -- so nothing changes from the current behaviour.
