// Raw Bitcoin transaction structure:
//
// field | size | type | description
// version | 4 | int32 | transaction version number
// n_tx_in | 1-9 | var_int | number of transaction inputs
// tx_in | 41+ | tx_in[] | list of transaction inputs
// n_tx_out | 1-9 | var_int | number of transaction outputs
// tx_out | 9+ | tx_out[] | list of transaction outputs
// lock_time | 4 | uint32 | block number / timestamp at which tx locked
//
// Transaction input (tx_in) structure:
//
// field | size | type | description
// previous | 36 | outpoint | Previous output transaction reference
// script_len | 1-9 | var_int | Length of the signature script
// sig_script | ? | uchar[] | Script for confirming transaction authorization
// sequence | 4 | uint32 | Sender transaction version
//
// OutPoint structure:
//
// field | size | type | description
// hash | 32 | char[32] | The hash of the referenced transaction
// index | 4 | uint32 | The index of this output in the referenced transaction
//
// Transaction output (tx_out) structure:
//
// field | size | type | description
// value | 8 | int64 | Transaction value (Satoshis)
// pk_script_len | 1-9 | var_int | Length of the public key script
// pk_script | ? | uchar[] | Public key as a Bitcoin script.
//
// Variable integers (var_int) can be encoded differently depending
// on the represented value, to save space. Variable integers always
// precede an array of a variable length data type (e.g. tx_in).
//
// Variable integer encodings as a function of represented value:
//
// value | bytes | format
// <0xFD (253) | 1 | uint8
// <=0xFFFF (65535)| 3 | 0xFD followed by length as uint16
// <=0xFFFF FFFF | 5 | 0xFE followed by length as uint32
// - | 9 | 0xFF followed by length as uint64
//
// Public key scripts `pk_script` are set on the output and can
// take a number of forms. The regular transaction script is
// called 'pay-to-pubkey-hash' (P2PKH):
//
// OP_DUP OP_HASH160 <pubKeyHash> OP_EQUALVERIFY OP_CHECKSIG
//
// OP_x are Bitcoin script opcodes. The bytes representation (including
// the 0x14 20-byte stack push) is:
//
// 0x76 0xA9 0x14 <pubKeyHash> 0x88 0xAC
//
// The <pubKeyHash> is the ripemd160 hash of the sha256 hash of
// the public key, preceded by a network version byte. (21 bytes total)
//
// Network version bytes: 0x00 (mainnet); 0x6f (testnet); 0x34 (namecoin)
//
// The Bitcoin address is derived from the pubKeyHash. The binary form is the
// pubKeyHash, plus a checksum at the end. The checksum is the first 4 bytes
// of the (32 byte) double sha256 of the pubKeyHash. (25 bytes total)
// This is converted to base58 to form the publicly used Bitcoin address.
// Mainnet P2PKH transaction scripts are to addresses beginning with '1'.
//
// P2SH ('pay to script hash') scripts only supply a script hash. The spender
// must then provide the script that would allow them to redeem this output.
// This allows for arbitrarily complex scripts to be funded using only a
// hash of the script, and moves the onus on providing the script from
// the spender to the redeemer.
//
// The P2SH script format is simple:
//
// OP_HASH160 <scriptHash> OP_EQUAL
//
// 0xA9 0x14 <scriptHash> 0x87
//
// The <scriptHash> is the ripemd160 hash of the sha256 hash of the
// redeem script. The P2SH address is derived from the scriptHash.
// Addresses are the scriptHash with a version prefix of 5, encoded as
// Base58check. These addresses begin with a '3'.

/*
The Dalmatian is a graceful, medium-sized dog with a sleek, muscular body. The tail is fairly long and has a slight, upward curve. The coat is short and dense, with brown or black spots on white. The Dalmatian sheds heavily, even though the coat is short. Frequent brushing is required to control shedding.

* 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

/*
Shibmurai brings you the most splendid meme token that you may find in cryptocurrency history.
Shibas are known for their spirited personality, foxy features and alert, confident behaviour.
Today they serve primarily not only as companion dogs but also widely considered as spiritual animals in contemporary Japan and the United States.
Samurai, noble warriors in ancient Japan.
It was supposed to be a stoic warrior who followed an unwritten code of conduct of Bushido, which held bravery, honour, and personal loyalty above life itself;
ritual suicide by disembowelment was institutionalized as a respected alternative to dishonour or defeat.
Everything about shiba tells you it is the ideal dog of each recognized breed; everything about samurai tells you it is the most glorious job that you can find in human history.
By combining the spirited animal Shiba and the glorious Samurai together, Shibmurai brings you the most splendid meme token that you may find in cryptocurrency history.

* @dev Implementation of the {IERC20} interface.

* 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}.

*
* *For a detailed writeup see our guide [How to implement supply
* mechanisms](https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226).*
*
* 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`.

// Methodology for Calculating LP Token Price //
// //
///////////////////////////////////////////////////////
// A naïve approach to calculate the price of LP tokens, assuming the protocol
// fee is zero, is to compute the price of the assets locked in its liquidity
// pool, and divide it by the total amount of LP tokens issued:
//
// (p_0 * r_0 + p_1 * r_1) / LP_supply (1)
//
// where r_0 and r_1 are the reserves of the two tokens held by the pool, and
// p_0 and p_1 are their respective prices in some reference unit of account.
//
// However, the price of LP tokens (i.e. pool shares) needs to be evaluated
// based on reserve values r_0 and r_1 that cannot be arbitraged, i.e. values
// that give the two halves of the pool equal economic value:
//
// r_0 * p_0 = r_1 * p_1 (2)
//
// Furthermore, two-asset constant product pools, neglecting fees, satisfy
// (before and after trades):
//
// r_0 * r_1 = k (3)
//
// Using (2) and (3) we can compute R_i, the arbitrage-free reserve values, in a
// manner that depends only on k (which can be derived from the current reserve
// balances, even if they are far from equilibrium) and market prices p_i
// obtained from a trusted source:
//
// R_0 = sqrt(k * p_1 / p_0) (4)
// and
// R_1 = sqrt(k * p_0 / p_1) (5)
//
// The value of an LP token is then, replacing (4) and (5) in (1):
//
// (p_0 * R_0 + p_1 * R_1) / LP_supply
// = 2 * sqrt(k * p_0 * p_1) / LP_supply (6)
//
// k can be re-expressed in terms of the current pool reserves r_0 and r_1:
//
// 2 * sqrt((r_0 * p_0) * (r_1 * p_1)) / LP_supply (7)
//
// The structure of (7) is well-suited for use in fixed-point EVM calculations, as the
// terms (r_0 * p_0) and (r_1 * p_1), being the values of the reserves in the reference unit,
// should have reasonably-bounded sizes. This reduces the likelihood of overflow due to
// tokens with very low prices but large total supplies.

// //
// Methodology for Calculating LP Token Price //
// //
///////////////////////////////////////////////////////
// A naïve approach to calculate the price of LP tokens, assuming the protocol
// fee is zero, is to compute the price of the assets locked in its liquidity
// pool, and divide it by the total amount of LP tokens issued:
//
// (p_0 * r_0 + p_1 * r_1) / LP_supply (1)
//
// where r_0 and r_1 are the reserves of the two tokens held by the pool, and
// p_0 and p_1 are their respective prices in some reference unit of account.
//
// However, the price of LP tokens (i.e. pool shares) needs to be evaluated
// based on reserve values r_0 and r_1 that cannot be arbitraged, i.e. values
// that give the two halves of the pool equal economic value:
//
// r_0 * p_0 = r_1 * p_1 (2)
//
// Furthermore, two-asset constant product pools, neglecting fees, satisfy
// (before and after trades):
//
// r_0 * r_1 = k (3)
//
// Using (2) and (3) we can compute R_i, the arbitrage-free reserve values, in a
// manner that depends only on k (which can be derived from the current reserve
// balances, even if they are far from equilibrium) and market prices p_i
// obtained from a trusted source:
//
// R_0 = sqrt(k * p_1 / p_0) (4)
// and
// R_1 = sqrt(k * p_0 / p_1) (5)
//
// The value of an LP token is then, replacing (4) and (5) in (1):
//
// (p_0 * R_0 + p_1 * R_1) / LP_supply
// = 2 * sqrt(k * p_0 * p_1) / LP_supply (6)
//
// k can be re-expressed in terms of the current pool reserves r_0 and r_1:
//
// 2 * sqrt((r_0 * p_0) * (r_1 * p_1)) / LP_supply (7)
//
// The structure of (7) is well-suited for use in fixed-point EVM calculations, as the
// terms (r_0 * p_0) and (r_1 * p_1), being the values of the reserves in the reference unit,
// should have reasonably-bounded sizes. This reduces the likelihood of overflow due to
// tokens with very low prices but large total supplies.

Inu Women’s Day (IWD)
Happy International Women's Day 2021! Inu Women’s day celebrates gender equality today and recognises the social, economic, cultural and political achievements of women. This token honours women's achievements and raises awareness about women's equality at the same time.
Despite accounting for half the world’s population, women made up more than two-thirds of the world’s illiterate people, an estimated 60 percent of chronically hungry and held just 28 percent of managerial positions globally in 2019 (almost the same as in 1995). Historically, women have been valued as less than their male counterparts.
Allow us to quote the respectable Malala Yousafzai “If we want to live in a more equal future, leaders must prioritise quality education. Educating young women can also help to prevent wars, mitigate the effects of climate change and make economics grow”
The purpose of this token not only celebrates the progress of women’s rights in this hundred years but also reminds mankind that our war against inequality isn’t over and still far from success.

Max supply: 10 Billion
Initial LP: 3 / 4

4% LP

2% Donation for women’s education

Oh, the fog! How choky, smoky, soaky! How freezy, sneezy, wheezy! Didn’t you like it, gentle reader?
London fog was so famous, or should that be infamous. Fog was such a common occurrence in Victorian Britain that it really has seeped into the consciousness of society that there is always a bloodthristy murderer hidding inside the fog, Jack the Ripper was one of the greatest or even legendary example among these myths.
"Jack the Ripper" terrorized the Whitechapel district in London's East End. He killed at least five prostitutes and mutilated their bodies in an unusual manner. Jack the Ripper was never captured, and remains one of England's, and the world's, most infamous criminals. He was like a phantom hiding inside fog and no one could even catch him.
Fog Inu believes that the true identity of the infamous serial killer is actually an Inu that had long been forgiven and turned into a ghost to avenge an irresponsible human.
Fog Inu aka "Jack the Ripper" has come to the cryptoworld and dedicated itself to punishing ALL SCAMMERS. We are here to urge every scammer to stop your irresponsible behavior in order to avoid any devastating consequences that could possibly lead to.
