/**
* @title Bloom account registry
* @notice Account Registry Logic provides a public interface for Bloom and users to
* create and control their Bloom Ids.
* Users can associate create and accept invites and associate additional addresses with their BloomId.
* As the Bloom protocol matures, this contract can be upgraded to enable new capabilities
* without needing to migrate the underlying Account Registry storage contract.
*
* In order to invite someone, a user must generate a new public key private key pair
* and sign their own ethereum address. The user provides this signature to the
* `createInvite` function where the public key is recovered and the invite is created.
* The inviter should then share the one-time-use private key out of band with the recipient.
* The recipient accepts the invite by signing their own address and passing that signature
* to the `acceptInvite` function. The contract should recover the same public key, demonstrating
* that the recipient knows the secret and is likely the person intended to receive the invite.
*
* @dev This invite model is supposed to aid usability by not requiring the inviting user to know
* the Ethereum address of the recipient. If the one-time-use private key is leaked then anyone
* else can accept the invite. This is an intentional tradeoff of this invite system. A well built
* dApp should generate the private key on the backend and sign the user's address for them. Likewise,
* the signing should also happen on the backend (not visible to the user) for signing an address to
* accept an invite. This reduces the private key exposure so that the dApp can still require traditional
* checks like verifying an associated email address before finally signing the user's Ethereum address.
*
* @dev The private key generated for this invite system should NEVER be used for an Ethereum address.
* The private key should be used only for the invite flow and then it should effectively be discarded.
*
* @dev If a user DOES know the address of the person they are inviting then they can still use this
* invite system. All they have to do then is sign the address of the user being invited and share the
* signature with them.

// To implement this library for multiple types with as little code
// repetition as possible, we write it in terms of a generic Set type with
// bytes32 values.
// The Set implementation uses private functions, and user-facing
// implementations (such as AddressSet) are just wrappers around the
// underlying Set.
// This means that we can only create new EnumerableSets for types that fit
// in bytes32.
/**
* @dev Intended to update the TWAP for a token based on accepting an update call from that token.
* expectation is to have this happen in the _beforeTokenTransfer function of ERC20.
* Provides a method for a token to register its price sourve adaptor.
* Provides a function for a token to register its TWAP updater. Defaults to token itself.
* Provides a function a tokent to set its TWAP epoch.
* Implements automatic closeing and opening up a TWAP epoch when epoch ends.
* Provides a function to report the TWAP from the last epoch when passed a token address.

/**
*
*
*
*
* ATTENTION!
*
* This code? IS NOT DESIGNED FOR ACTUAL USE.
*
* The author of this code really wishes you wouldn't send your ETH to it, but it's been
* done with P3D and there are very happy users because of it.
*
* No, seriously. It's probablly illegal anyway. So don't do it.
*
* Let me repeat that: Don't actually send money to this contract. You are
* likely breaking several local and national laws in doing so.
*
* This code is intended to educate. Nothing else. If you use it, expect S.W.A.T
* teams at your door. I wrote this code because I wanted to experiment
* with smart contracts, and I think code should be open source. So consider
* it public domain, No Rights Reserved. Participating in pyramid schemes
* is genuinely illegal so just don't even think about going beyond
* reading the code and understanding how it works.
*
* Seriously. I'm not kidding. It's probablly broken in some critical way anyway
* and will suck all your money out your wallet, install a virus on your computer
* sleep with your wife, kidnap your children and sell them into slavery,
* make you forget to file your taxes, and give you cancer.
*
*
* What it does:
*
* It takes 50% of the ETH in it and buys tokens.
* It takes 50% of the ETH in it and pays back depositors.
* Depositors get in line and are paid out in order of deposit, plus the deposit
* percent.
* The tokens collect dividends, which in turn pay into the payout pool
* to be split 50/50.
*
* If you're seeing this contract in it's initial configuration, it should be
* set to 200% (double deposits), and pointed at PoWH:
* 0xB3775fB83F7D12A36E0475aBdD1FCA35c091efBe
*
* But you should verify this for yourself.

Multipliers contract: returns 111%-141% of each investment!
Automatic payouts!
No bugs, no backdoors, NO OWNER - fully automatic!
Made and checked by professionals!
1. Send any sum to smart contract address
- sum from 0.01 to 10 ETH
- min 250000 gas limit
- you are added to a queue
2. Wait a little bit
3. ...
4. PROFIT! You have got 111-141%
How is that?
1. The first investor in the queue (you will become the
first in some time) receives next investments until
it become 111-141% of his initial investment.
2. You will receive payments in several parts or all at once
3. Once you receive 111-141% of your initial investment you are
removed from the queue.
4. You can make multiple deposits
5. The balance of this contract should normally be 0 because
all the money are immediately go to payouts
6. The more deposits you make the more multiplier you get. See MULTIPLIERS var
7. If you are the last depositor (no deposits after you in 30 mins)
you get 5% of all the ether that were on the contract. Send 0 to withdraw it.
Do it BEFORE NEXT RESTART!
So the last pays to the first (or to several first ones
if the deposit big enough) and the investors paid 111-141% are removed from the queue

Контракт Умножитель: возвращает 111%-141% от вашего депозита!
Автоматические выплаты!
Без ошибок, дыр, автоматический - для выплат НЕ НУЖНА администрация!
Создан и проверен профессионалами!
1. Пошлите любую ненулевую сумму на адрес контракта
- сумма от 0.01 до 10 ETH
- gas limit минимум 250000
- вы встанете в очередь
2. Немного подождите
3. ...
4. PROFIT! Вам пришло 111%-141% от вашего депозита.
Как это возможно?
1. Первый инвестор в очереди (вы станете первым очень скоро) получает выплаты от
новых инвесторов до тех пор, пока не получит 111%-141% от своего депозита
2. Выплаты могут приходить несколькими частями или все сразу
3. Как только вы получаете 111%-141% от вашего депозита, вы удаляетесь из очереди
4. Вы можете делать несколько депозитов сразу
5. Баланс этого контракта должен обычно быть в районе 0, потому что все поступления
сразу же направляются на выплаты
6. Чем больше вы сделали депозитов, тем больший процент вы получаете на очередной депозит
Смотрите переменную MULTIPLIERS в контракте
7. Если вы последний вкладчик (после вас не сделан депозит в течение 30 минут), то вы можете
забрать призовой фонд - 5% от эфира, прошедшего через контракт. Пошлите 0 на контракт
с газом не менее 350000, чтобы его получить.
Таким образом, последние платят первым, и инвесторы, достигшие выплат 111%-141% от депозита,
удаляются из очереди, уступая место остальным

/**
* @dev Implementation of the {IERC20} interface.
*
* This implementation is agnostic to the way tokens are created. This means
* that a supply mechanism has to be added in a derived contract using {_mint}.
* For a generic mechanism see {ERC20PresetMinterPauser}.
*
* TIP: For a detailed writeup see our guide
* https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How
* to implement supply mechanisms].
*
* We have followed general OpenZeppelin guidelines: functions revert instead
* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
* functions have been added to mitigate the well-known issues around setting
* allowances. See {IERC20-approve}.
