When a trove is liquidated, then depending on system conditions, some of its ZUSD debt gets offset with ZUSD in the Stability Pool: that is, the offset debt evaporates, and an equal amount of ZUSD tokens in the Stability Pool is burned. Thus, a liquidation causes each depositor to receive a ZUSD loss, in proportion to their deposit as a share of total deposits. They also receive an ETH gain, as the ETH collateral of the liquidated trove is distributed among Stability depositors, in the same proportion. When a liquidation occurs, it depletes every deposit by the same fraction: for example, a liquidation that depletes 40% of the total ZUSD in the Stability Pool, depletes 40% of each deposit. A deposit that has experienced a series of liquidations is termed a \\\"compounded deposit\\\": each liquidation depletes the deposit, multiplying it by some factor in range ]0,1[ --- IMPLEMENTATION --- We use a highly scalable method of tracking deposits and ETH gains that has O(1) complexity. When a liquidation occurs, rather than updating each depositor's deposit and ETH gain, we simply update two state variables: a product P, and a sum S. A mathematical manipulation allows us to factor out the initial deposit, and accurately track all depositors' compounded deposits and accumulated ETH gains over time, as liquidations occur, using just these two variables P and S. When depositors join the Stability Pool, they get a snapshot of the latest P and S: P_t and S_t, respectively. The formula for a depositor's accumulated ETH gain is derived here: https://github.com/liquity/dev/blob/main/packages/contracts/mathProofs/Scalable%20Compounding%20Stability%20Pool%20Deposits.pdf For a given deposit d_t, the ratio P/P_t tells us the factor by which a deposit has decreased since it joined the Stability Pool, and the term d_t * (S - S_t)/P_t gives us the deposit's total accumulated ETH gain. Each liquidation updates the product P and sum S. After a series of liquidations, a compounded deposit and corresponding ETH gain can be calculated using the initial deposit, the depositor\\u2019s snapshots of P and S, and the latest values of P and S. Any time a depositor updates their deposit (withdrawal, top-up) their accumulated ETH gain is paid out, their new deposit is recorded (based on their latest compounded deposit and modified by the withdrawal/top-up), and they receive new snapshots of the latest P and S. Essentially, they make a fresh deposit that overwrites the old one. --- SCALE FACTOR --- Since P is a running product in range ]0,1] that is always-decreasing, it should never reach 0 when multiplied by a number in range ]0,1[. Unfortunately, Solidity floor division always reaches 0, sooner or later. A series of liquidations that nearly empty the Pool (and thus each multiply P by a very small number in range ]0,1[ ) may push P to its 18 digit decimal limit, and round it to 0, when in fact the Pool hasn't been emptied: this would break deposit tracking. So, to track P accurately, we use a scale factor: if a liquidation would cause P to decrease to <1e-9 (and be rounded to 0 by Solidity), we first multiply P by 1e9, and increment a currentScale factor by 1. The added benefit of using 1e9 for the scale factor (rather than 1e18) is that it ensures negligible precision loss close to the scale boundary: when P is at its minimum value of 1e9, the relative precision loss in P due to floor division is only on the order of 1e-9. --- EPOCHS --- Whenever a liquidation fully empties the Stability Pool, all deposits should become 0. However, setting P to 0 would make P be 0 forever, and break all future reward calculations. So, every time the Stability Pool is emptied by a liquidation, we reset P = 1 and currentScale = 0, and increment the currentEpoch by 1. --- TRACKING DEPOSIT OVER SCALE CHANGES AND EPOCHS --- When a deposit is made, it gets snapshots of the currentEpoch and the currentScale. When calculating a compounded deposit, we compare the current epoch to the deposit's epoch snapshot. If the current epoch is newer, then the deposit was present during a pool-emptying liquidation, and necessarily has been depleted to 0. Otherwise, we then compare the current scale to the deposit's scale snapshot. If they're equal, the compounded deposit is given by d_t * P/P_t. If it spans one scale change, it is given by d_t * P/(P_t * 1e9). If it spans more than one scale change, we define the compounded deposit as 0, since it is now less than 1e-9'th of its initial value (e.g. a deposit of 1 billion ZUSD has depleted to < 1 ZUSD). --- TRACKING DEPOSITOR'S ETH GAIN OVER SCALE CHANGES AND EPOCHS --- In the current epoch, the latest value of S is stored upon each scale change, and the mapping (scale -> S) is stored for each epoch. This allows us to calculate a deposit's accumulated ETH gain, during the epoch in which the deposit was non-zero and earned ETH. We calculate the depositor's accumulated ETH gain for the scale at which they made the deposit, using the ETH gain formula: e_1 = d_t * (S - S_t) / P_t and also for scale after, taking care to divide the latter by a factor of 1e9: e_2 = d_t * S / (P_t * 1e9) The gain in the second scale will be full, as the starting point was in the previous scale, thus no need to subtract anything. The deposit therefore was present for reward events from the beginning of that second scale. S_i-S_t + S_{i+1} .<--------.------------> . . . S_i . S_{i+1} <--.-------->.<-----------> S_t. . <->. . t . |---+---------|-------------|-----... i i+1 The sum of (e_1 + e_2) captures the depositor's total accumulated ETH gain, handling the case where their deposit spanned one scale change. We only care about gains across one scale change, since the compounded deposit is defined as being 0 once it has spanned more than one scale change. --- UPDATING P WHEN A LIQUIDATION OCCURS --- Please see the implementation spec in the proof document, which closely follows on from the compounded deposit / ETH gain derivations: https://github.com/liquity/liquity/blob/master/papers/Scalable_Reward_Distribution_with_Compounding_Stakes.pdf --- SOV ISSUANCE TO STABILITY POOL DEPOSITORS --- An SOV issuance event occurs at every deposit operation, and every liquidation. Each deposit is tagged with the address of the front end through which it was made. All deposits earn a share of the issued SOV in proportion to the deposit as a share of total deposits. The SOV earned by a given deposit, is split between the depositor and the front end through which the deposit was made, based on the front end's kickbackRate. Please see the system Readme for an overview: https://github.com/liquity/dev/blob/main/README.md#zero-issuance-to-stability-providers We use the same mathematical product-sum approach to track SOV gains for depositors, where 'G' is the sum corresponding to SOV gains. The product P (and snapshot P_t) is re-used, as the ratio P/P_t tracks a deposit's depletion due to liquidations.\",\"version\":1}},\"settings\":{\"compilationTarget\":{\"contracts/StabilityPool.sol\":\"StabilityPool\"},\"evmVersion\":\"istanbul\",\"libraries\":{},\"metadata\":{\"bytecodeHash\":\"ipfs\",\"useLiteralContent\":true},\"optimizer\":{\"enabled\":true,\"runs\":100},\"remappings\":[]},\"sources\":{\"contracts/Dependencies/BaseMath.sol\":{\"content\":\"// SPDX-License-Identifier: MIT\\npragma solidity 0.6.11;\\n\\n\\ncontract BaseMath {\\n uint constant public DECIMAL_PRECISION = 1e18;\\n}\\n\",\"keccak256\":\"0x7e1369ca5cb09e818e345a2def19a261401f79c985a6030b55b7311dd6f53be4\",\"license\":\"MIT\"},\"contracts/Dependencies/CheckContract.sol\":{\"content\":\"// SPDX-License-Identifier: MIT\\n\\npragma solidity 0.6.11;\\n\\n\\ncontract CheckContract {\\n /**\\n * @dev Check that the account is an already deployed non-destroyed contract.\\n * See: https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/utils/Address.sol#L12\\n */\\n function checkContract(address _account) internal view {\\n require(_account != address(0), \\\"Account cannot be zero address\\\");\\n\\n uint256 size;\\n // solhint-disable-next-line no-inline-assembly\\n assembly { size := extcodesize(_account) }\\n require(size > 0, \\\"Account code size cannot be zero\\\");\\n }\\n}\\n\",\"keccak256\":\"0x4c7dc4d0197c27ebc7de671b00458a9ff45f57223aeb520e6ddd2eb6d2d89e5c\",\"license\":\"MIT\"},\"contracts/Dependencies/IERC20.sol\":{\"content\":\"// SPDX-License-Identifier: MIT\\n\\npragma solidity 0.6.11;\\n\\n/**\\n * Based on the OpenZeppelin IER20 interface:\\n * https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/IERC20.sol\\n *\\n * @dev Interface of the ERC20 standard as defined in the EIP.\\n */\\ninterface IERC20 {\\n /**\\n * @dev Returns the amount of tokens in existence.\\n */\\n function totalSupply() external view returns (uint256);\\n\\n /**\\n * @dev Returns the amount of tokens owned by `account`.\\n */\\n function balanceOf(address account) external view returns (uint256);\\n\\n /**\\n * @dev Moves `amount` tokens from the caller's account to `recipient`.\\n *\\n * Returns a boolean value indicating whether the operation succeeded.\\n *\\n * Emits a {Transfer} event.\\n */\\n function transfer(address recipient, uint256 amount) external returns (bool);\\n\\n /**\\n * @dev Returns the remaining number of tokens that `spender` will be\\n * allowed to spend on behalf of `owner` through {transferFrom}.

Stability Pool depositors.\\n *\\n * When a trove is liquidated, then depending on system conditions, some of its ZUSD debt gets offset with\\n * ZUSD in the Stability Pool: that is, the offset debt evaporates, and an equal amount of ZUSD tokens in the Stability Pool is burned.\\n *\\n * Thus, a liquidation causes each depositor to receive a ZUSD loss, in proportion to their deposit as a share of total deposits.\\n * They also receive an ETH gain, as the ETH collateral of the liquidated trove is distributed among Stability depositors,\\n * in the same proportion.\\n *\\n * When a liquidation occurs, it depletes every deposit by the same fraction: for example, a liquidation that depletes 40%\\n * of the total ZUSD in the Stability Pool, depletes 40% of each deposit.\\n *\\n * A deposit that has experienced a series of liquidations is termed a \\\"compounded deposit\\\": each liquidation depletes the deposit,\\n * multiplying it by some factor in range ]0,1[\\n *\\n *\\n * --- IMPLEMENTATION ---\\n *\\n * We use a highly scalable method of tracking deposits and ETH gains that has O(1) complexity.\\n *\\n * When a liquidation occurs, rather than updating each depositor's deposit and ETH gain, we simply update two state variables:\\n * a product P, and a sum S.\\n *\\n * A mathematical manipulation allows us to factor out the initial deposit, and accurately track all depositors' compounded deposits\\n * and accumulated ETH gains over time, as liquidations occur, using just these two variables P and S. When depositors join the\\n * Stability Pool, they get a snapshot of the latest P and S: P_t and S_t, respectively.\\n *\\n * The formula for a depositor's accumulated ETH gain is derived here:\\n * https://github.com/liquity/dev/blob/main/packages/contracts/mathProofs/Scalable%20Compounding%20Stability%20Pool%20Deposits.pdf\\n *\\n * For a given deposit d_t, the ratio P/P_t tells us the factor by which a deposit has decreased since it joined the Stability Pool,\\n * and the term d_t * (S - S_t)/P_t gives us the deposit's total accumulated ETH gain.\\n *\\n * Each liquidation updates the product P and sum S. After a series of liquidations, a compounded deposit and corresponding ETH gain\\n * can be calculated using the initial deposit, the depositor\\u2019s snapshots of P and S, and the latest values of P and S.\\n *\\n * Any time a depositor updates their deposit (withdrawal, top-up) their accumulated ETH gain is paid out, their new deposit is recorded\\n * (based on their latest compounded deposit and modified by the withdrawal/top-up), and they receive new snapshots of the latest P and S.\\n * Essentially, they make a fresh deposit that overwrites the old one.\\n *\\n *\\n * --- SCALE FACTOR ---\\n *\\n * Since P is a running product in range ]0,1] that is always-decreasing, it should never reach 0 when multiplied by a number in range ]0,1[.\\n * Unfortunately, Solidity floor division always reaches 0, sooner or later.\\n *\\n * A series of liquidations that nearly empty the Pool (and thus each multiply P by a very small number in range ]0,1[ ) may push P\\n * to its 18 digit decimal limit, and round it to 0, when in fact the Pool hasn't been emptied: this would break deposit tracking.\\n *\\n * So, to track P accurately, we use a scale factor: if a liquidation would cause P to decrease to <1e-9 (and be rounded to 0 by Solidity),\\n * we first multiply P by 1e9, and increment a currentScale factor by 1.\\n *\\n * The added benefit of using 1e9 for the scale factor (rather than 1e18) is that it ensures negligible precision loss close to the\\n * scale boundary: when P is at its minimum value of 1e9, the relative precision loss in P due to floor division is only on the\\n * order of 1e-9.\\n *\\n * --- EPOCHS ---\\n *\\n * Whenever a liquidation fully empties the Stability Pool, all deposits should become 0. However, setting P to 0 would make P be 0\\n * forever, and break all future reward calculations.\\n *\\n * So, every time the Stability Pool is emptied by a liquidation, we reset P = 1 and currentScale = 0, and increment the currentEpoch by 1.\\n *\\n * --- TRACKING DEPOSIT OVER SCALE CHANGES AND EPOCHS ---\\n *\\n * When a deposit is made, it gets snapshots of the currentEpoch and the currentScale.\\n *\\n * When calculating a compounded deposit, we compare the current epoch to the deposit's epoch snapshot. If the current epoch is newer,\\n * then the deposit was present during a pool-emptying liquidation, and necessarily has been depleted to 0.\\n *\\n * Otherwise, we then compare the current scale to the deposit's scale snapshot. If they're equal, the compounded deposit is given by d_t * P/P_t.\\n * If it spans one scale change, it is given by d_t * P/(P_t * 1e9). If it spans more than one scale change, we define the compounded deposit\\n * as 0, since it is now less than 1e-9'th of its initial value (e.g. a deposit of 1 billion ZUSD has depleted to < 1 ZUSD).\\n *\\n *\\n * --- TRACKING DEPOSITOR'S ETH GAIN OVER SCALE CHANGES AND EPOCHS ---\\n *\\n * In the current epoch, the latest value of S is stored upon each scale change, and the mapping (scale -> S) is stored for each epoch.\\n *\\n * This allows us to calculate a deposit's accumulated ETH gain, during the epoch in which the deposit was non-zero and earned ETH.\\n *\\n * We calculate the depositor's accumulated ETH gain for the scale at which they made the deposit, using the ETH gain formula:\\n * e_1 = d_t * (S - S_t) / P_t\\n *\\n * and also for scale after, taking care to divide the latter by a factor of 1e9:\\n * e_2 = d_t * S / (P_t * 1e9)\\n *\\n * The gain in the second scale will be full, as the starting point was in the previous scale, thus no need to subtract anything.\\n * The deposit therefore was present for reward events from the beginning of that second scale.\\n *\\n * S_i-S_t + S_{i+1}\\n * .<--------.------------>\\n * . .\\n * . S_i . S_{i+1}\\n * <--.-------->.<----------->\\n * S_t. .\\n * <->. .\\n * t .\\n * |---+---------|-------------|-----...\\n * i i+1\\n *\\n * The sum of (e_1 + e_2) captures the depositor's total accumulated ETH gain, handling the case where their\\n * deposit spanned one scale change. We only care about gains across one scale change, since the compounded\\n * deposit is defined as being 0 once it has spanned more than one scale change.\\n *\\n *\\n * --- UPDATING P WHEN A LIQUIDATION OCCURS ---\\n *\\n * Please see the implementation spec in the proof document, which closely follows on from the compounded deposit / ETH gain derivations:\\n * https://github.com/liquity/liquity/blob/master/papers/Scalable_Reward_Distribution_with_Compounding_Stakes.pdf\\n *\\n *\\n * --- SOV ISSUANCE TO STABILITY POOL DEPOSITORS ---\\n *\\n * An SOV issuance event occurs at every deposit operation, and every liquidation.\\n *\\n * Each deposit is tagged with the address of the front end through which it was made.\\n *\\n * All deposits earn a share of the issued SOV in proportion to the deposit as a share of total deposits. The SOV earned\\n * by a given deposit, is split between the depositor and the front end through which the deposit was made, based on the front end's kickbackRate.\\n *\\n * Please see the system Readme for an overview:\\n * https://github.com/liquity/dev/blob/main/README.md#zero-issuance-to-stability-providers\\n *\\n * We use the same mathematical product-sum approach to track SOV gains for depositors, where 'G' is the sum corresponding to SOV gains.\\n * The product P (and snapshot P_t) is re-used, as the ratio P/P_t tracks a deposit's depletion due to liquidations.\\n *\\n */\\ncontract StabilityPool is LiquityBase, StabilityPoolStorage, CheckContract, IStabilityPool {\\n using LiquitySafeMath128 for uint128;\\n address private constant ADDRESS_ZERO = address(0);\\n IPermit2 public immutable permit2;\\n\\n // --- Events ---\\n\\n event StabilityPoolETHBalanceUpdated(uint256 _newBalance);\\n event StabilityPoolZUSDBalanceUpdated(uint256 _newBalance);\\n\\n event BorrowerOperationsAddressChanged(address _newBorrowerOperationsAddress);\\n event TroveManagerAddressChanged(address _newTroveManagerAddress);\\n event ActivePoolAddressChanged(address _newActivePoolAddress);\\n event DefaultPoolAddressChanged(address _newDefaultPoolAddress);\\n event ZUSDTokenAddressChanged(address _newZUSDTokenAddress);\\n event SortedTrovesAddressChanged(address _newSortedTrovesAddress);\\n event PriceFeedAddressChanged(address _newPriceFeedAddress);\\n event CommunityIssuanceAddressChanged(address _newCommunityIssuanceAddress);\\n\\n event P_Updated(uint256 _P);\\n event S_Updated(uint256 _S, uint128 _epoch, uint128 _scale);\\n event G_Updated(uint256 _G, uint128 _epoch, uint128 _scale);\\n event EpochUpdated(uint128 _currentEpoch);\\n event ScaleUpdated(uint128 _currentScale);\\n\\n event FrontEndRegistered(address indexed _frontEnd, uint256 _kickbackRate);\\n event FrontEndTagSet(address indexed _depositor, address indexed _frontEnd);\\n\\n event DepositSnapshotUpdated(address indexed _depositor, uint256 _P, uint256 _S, uint256 _G);\\n event FrontEndSnapshotUpdated(address indexed _frontEnd, uint256 _P, uint256 _G);\\n event UserDepositChanged(address indexed _depositor, uint256 _newDeposit);\\n event FrontEndStakeChanged(\\n address indexed _frontEnd,\\n uint256 _newFrontEndStake,\\n address _depositor\\n );\\n\\n event ETHGainWithdrawn(address indexed _depositor, uint256 _ETH, uint256 _ZUSDLoss);\\n event SOVPaidToDepositor(address indexed _depositor, uint256 _SOV);\\n event SOVPaidToFrontEnd(address indexed _frontEnd, uint256 _SOV);\\n event EtherSent(address _to, uint256 _amount);\\n\\n /** Constructor */\\n constructor(address _permit2) public {\\n permit2 = IPermit2(_permit2);\\n }\\n\\n // --- Contract setters ---\\n\\n function setAddresses(\\n address _liquityBaseParamsAddress,\\n address _borrowerOperationsAddress,\\n address _troveManagerAddress,\\n address _activePoolAddress,\\n address _zusdTokenAddress,\\n address _sortedTrovesAddress,\\n address _priceFeedAddress,\\n address _communityIssuanceAddress\\n ) external override onlyOwner {\\n checkContract(_liquityBaseParamsAddress);\\n checkContract(_borrowerOperationsAddress);\\n checkContract(_troveManagerAddress);\\n checkContract(_activePoolAddress);\\n checkContract(_zusdTokenAddress);\\n checkContract(_sortedTrovesAddress);\\n checkContract(_priceFeedAddress);\\n checkContract(_communityIssuanceAddress);\\n\\n P = DECIMAL_PRECISION;\\n\\n liquityBaseParams = ILiquityBaseParams(_liquityBaseParamsAddress);\\n borrowerOperations = IBorrowerOperations(_borrowerOperationsAddress);\\n troveManager = ITroveManager(_troveManagerAddress);\\n activePool = IActivePool(_activePoolAddress);\\n zusdToken = IZUSDToken(_zusdTokenAddress);\\n sortedTroves = ISortedTroves(_sortedTrovesAddress);\\n priceFeed = IPriceFeed(_priceFeedAddress);\\n communityIssuance = ICommunityIssuance(_communityIssuanceAddress);\\n\\n emit BorrowerOperationsAddressChanged(_borrowerOperationsAddress);\\n emit TroveManagerAddressChanged(_troveManagerAddress);\\n emit ActivePoolAddressChanged(_activePoolAddress);\\n emit ZUSDTokenAddressChanged(_zusdTokenAddress);\\n emit SortedTrovesAddressChanged(_sortedTrovesAddress);\\n emit PriceFeedAddressChanged(_priceFeedAddress);\\n emit CommunityIssuanceAddressChanged(_communityIssuanceAddress);\\n }\\n\\n /**\\n * @dev setter function specific for community issuance contract.\\n * @param _communityIssuanceAddress address of new community issuance contract.\\n */\\n function setCommunityIssuanceAddress(address _communityIssuanceAddress) external onlyOwner {\\n checkContract(_communityIssuanceAddress);\\n communityIssuance = ICommunityIssuance(_communityIssuanceAddress);\\n emit CommunityIssuanceAddressChanged(_communityIssuanceAddress);\\n }\\n\\n // --- Getters for public variables.

When a trove is liquidated, then depending on system conditions, some of its ZUSD debt gets offset with ZUSD in the Stability Pool: that is, the offset debt evaporates, and an equal amount of ZUSD tokens in the Stability Pool is burned. Thus, a liquidation causes each depositor to receive a ZUSD loss, in proportion to their deposit as a share of total deposits. They also receive an ETH gain, as the ETH collateral of the liquidated trove is distributed among Stability depositors, in the same proportion. When a liquidation occurs, it depletes every deposit by the same fraction: for example, a liquidation that depletes 40% of the total ZUSD in the Stability Pool, depletes 40% of each deposit. A deposit that has experienced a series of liquidations is termed a \"compounded deposit\": each liquidation depletes the deposit, multiplying it by some factor in range ]0,1[ --- IMPLEMENTATION --- We use a highly scalable method of tracking deposits and ETH gains that has O(1) complexity. When a liquidation occurs, rather than updating each depositor's deposit and ETH gain, we simply update two state variables: a product P, and a sum S. A mathematical manipulation allows us to factor out the initial deposit, and accurately track all depositors' compounded deposits and accumulated ETH gains over time, as liquidations occur, using just these two variables P and S. When depositors join the Stability Pool, they get a snapshot of the latest P and S: P_t and S_t, respectively. The formula for a depositor's accumulated ETH gain is derived here: https://github.com/liquity/dev/blob/main/packages/contracts/mathProofs/Scalable%20Compounding%20Stability%20Pool%20Deposits.pdf For a given deposit d_t, the ratio P/P_t tells us the factor by which a deposit has decreased since it joined the Stability Pool, and the term d_t * (S - S_t)/P_t gives us the deposit's total accumulated ETH gain. Each liquidation updates the product P and sum S. After a series of liquidations, a compounded deposit and corresponding ETH gain can be calculated using the initial deposit, the depositor’s snapshots of P and S, and the latest values of P and S. Any time a depositor updates their deposit (withdrawal, top-up) their accumulated ETH gain is paid out, their new deposit is recorded (based on their latest compounded deposit and modified by the withdrawal/top-up), and they receive new snapshots of the latest P and S. Essentially, they make a fresh deposit that overwrites the old one. --- SCALE FACTOR --- Since P is a running product in range ]0,1] that is always-decreasing, it should never reach 0 when multiplied by a number in range ]0,1[. Unfortunately, Solidity floor division always reaches 0, sooner or later. A series of liquidations that nearly empty the Pool (and thus each multiply P by a very small number in range ]0,1[ ) may push P to its 18 digit decimal limit, and round it to 0, when in fact the Pool hasn't been emptied: this would break deposit tracking. So, to track P accurately, we use a scale factor: if a liquidation would cause P to decrease to <1e-9 (and be rounded to 0 by Solidity), we first multiply P by 1e9, and increment a currentScale factor by 1. The added benefit of using 1e9 for the scale factor (rather than 1e18) is that it ensures negligible precision loss close to the scale boundary: when P is at its minimum value of 1e9, the relative precision loss in P due to floor division is only on the order of 1e-9. --- EPOCHS --- Whenever a liquidation fully empties the Stability Pool, all deposits should become 0. However, setting P to 0 would make P be 0 forever, and break all future reward calculations. So, every time the Stability Pool is emptied by a liquidation, we reset P = 1 and currentScale = 0, and increment the currentEpoch by 1. --- TRACKING DEPOSIT OVER SCALE CHANGES AND EPOCHS --- When a deposit is made, it gets snapshots of the currentEpoch and the currentScale. When calculating a compounded deposit, we compare the current epoch to the deposit's epoch snapshot. If the current epoch is newer, then the deposit was present during a pool-emptying liquidation, and necessarily has been depleted to 0. Otherwise, we then compare the current scale to the deposit's scale snapshot. If they're equal, the compounded deposit is given by d_t * P/P_t. If it spans one scale change, it is given by d_t * P/(P_t * 1e9). If it spans more than one scale change, we define the compounded deposit as 0, since it is now less than 1e-9'th of its initial value (e.g. a deposit of 1 billion ZUSD has depleted to < 1 ZUSD). --- TRACKING DEPOSITOR'S ETH GAIN OVER SCALE CHANGES AND EPOCHS --- In the current epoch, the latest value of S is stored upon each scale change, and the mapping (scale -> S) is stored for each epoch. This allows us to calculate a deposit's accumulated ETH gain, during the epoch in which the deposit was non-zero and earned ETH. We calculate the depositor's accumulated ETH gain for the scale at which they made the deposit, using the ETH gain formula: e_1 = d_t * (S - S_t) / P_t and also for scale after, taking care to divide the latter by a factor of 1e9: e_2 = d_t * S / (P_t * 1e9) The gain in the second scale will be full, as the starting point was in the previous scale, thus no need to subtract anything. The deposit therefore was present for reward events from the beginning of that second scale. S_i-S_t + S_{i+1} .<--------.------------> . . . S_i . S_{i+1} <--.-------->.<-----------> S_t. . <->. . t . |---+---------|-------------|-----... i i+1 The sum of (e_1 + e_2) captures the depositor's total accumulated ETH gain, handling the case where their deposit spanned one scale change. We only care about gains across one scale change, since the compounded deposit is defined as being 0 once it has spanned more than one scale change. --- UPDATING P WHEN A LIQUIDATION OCCURS --- Please see the implementation spec in the proof document, which closely follows on from the compounded deposit / ETH gain derivations: https://github.com/liquity/liquity/blob/master/papers/Scalable_Reward_Distribution_with_Compounding_Stakes.pdf --- SOV ISSUANCE TO STABILITY POOL DEPOSITORS --- An SOV issuance event occurs at every deposit operation, and every liquidation. Each deposit is tagged with the address of the front end through which it was made. All deposits earn a share of the issued SOV in proportion to the deposit as a share of total deposits. The SOV earned by a given deposit, is split between the depositor and the front end through which the deposit was made, based on the front end's kickbackRate. Please see the system Readme for an overview: https://github.com/liquity/dev/blob/main/README.md#zero-issuance-to-stability-providers We use the same mathematical product-sum approach to track SOV gains for depositors, where 'G' is the sum corresponding to SOV gains. The product P (and snapshot P_t) is re-used, as the ratio P/P_t tracks a deposit's depletion due to liquidations.", "version": 1 }, "storageLayout": { "storage": [ { "astId": 5495, "contract":
