About Niubi Swap

Niubiswap is a decentralized exchange (DEX) which runs on Binance Smart Chain, it uses the same automated market-making (AMM) model as Uniswap (ETH) and more recently with Pancakeswap (BSC), and features a native governance token called NIU that is fully community distributed and is capable of trading all tokens issued on Ethereum (ERC-20) and Binance Smart Chain.

Niubiswap is mainly built by and for Chinese and Asian communities focusing on the mission of developing and giving access to the best DeFi services for Asian countries. (China, Korea, Vietnam, Japan and even Thailand…) the project is runned by a decentralized organization that belongs to its users. The tokens smart contracts were setup the first day of the Chinese New Year (Niu / Ox year) and the platform launch is planned exactly one week after. Audit is coming (CertiK)

The DeFi with diverse Yield Farming Swap protocols initially started on Ethereum with Uniswap, then Sushiswap, now leveraging the power of BSC with PancakeSwap and more recently with different forks (KebabFinance, PandaYield, etc.) is attracting a lot of users and liquidity.

As servant of trustless and highly decentralized financial infrastructure movement Niubiswap organization aim to commit the initial Ethereum’s vision, to the ideals of permissionless access, security, and immutability, all indispensable components for a future where anyone in the world can access financial services without fear of discrimination or counterparty risk. We want to achieve this in a P2P and decentralized way.

AMM DEX is a unique opportunity to build new decentralized and autonomous organizations with unique strategies and models. Niubiswap is experiencing one we think is the most solid design to achieve this goal.

In a crowded marketplace with multiple competitors, Niubi offers three critically important benefits: fast and cheap trades, community-driven development, and a fair and open token distribution.

We focus on building a playful DeFi ecosystem targeting Asian communities where everyone is welcomed, by proposing different services as a DEX and Yield Farming platform, you can farm Niubi token (NIU) by providing Liquidity, and also stack it for Hongbao Token (BAO) which rewards you with more NIU or other tokens like (CAKE/BUSD/BTCB/BNB/CAKE/ETH)and Polkadot in its core design and focus it with our investment fund. This choice will be rediscussed every month in the governance process using the Niubi token and snapshot decision-making platform. See Niubiswap Governance

Niubiswap tokenomics

As an AMM DEX on Binance Smart Chain, Niubiswap support all Binance Smart Chain tokens (BEP-20), and comes with two natives tokens, while supporting a bag of several project like Binance, Monero, Cosmos, Polkadot.

Hence our ecosystem tokens are :

  • Binance ecosystem: BNB / BUSD / BTCB + All (BSC) BEP-20 tokens
  • Niubiswap core: NIU (BEP-20 tokens)
  • Investment fund support: ETH(Ethereum),BNB(Binance Coin),DOT(Polkadot)

On Niubiswap you can farm Niubi token (NIU) by providing Liquidity on the pools just on like any other Yield Farm, and also stack it in the HongBao Zone for Hongbao Token (BAO) which rewards you with more NIU or other tokens (CAKE/BUSD/BTCB/BNB/DOT/CAKE/ETH/EGG/BSCPAD) depending on the which Hongbao you decide to stake your Niubi tokens.

About 10% of minted tokens, go in the Niubi DAO Fund which will be governed by Niubiswap organization in a decentralized way, one month after launch. The first month, those funds will be invested by core founders, in (BNB/DOT/ATOM/BSCPAD), to fill the different Hongbao Pools, and reward Niubi’stakers.

Niubi Token (NIU)

More traction, more R&D, more risks, raising the question of transparency, governance, token economics, centralization. Niubiswap is focusing on solving those issues by-design with a decentralized and community-driven strategy. Featuring a native governance token called NIU that is fully community distributed, decisions will be taken by NIU holders in a DAO Gov platform, where are partnering with the famous Snapshot using weekly polls. See Niubiswap Governance

NIU Fair Distribution: A 100% Community-Driven Governance Token

To reinforce the project’s commitment to being created solely for the benefit of users, Niubiswap is following a fair launch model with its governance token (NIU). However, while NIU will enable all the governance activities of Niubiswap, and therefore its future development, governance proposals will not start until one months after the launch of Niubiswap. This waiting period of one month is to ensure that enough NIU is distributed to the community and that the Niubiswap foundations and governance model are setup correctly for decentralization.

AMM Dex and Niubiswap Exchange

AMM DEX

AMM DEX is a unique opportunity to build new decentralized and autonomous organizations with unique strategies and models. Niubiswap is experiencing one we think is the most solid design to achieve this goal.

For those who are unfamiliar with AMM’s, it allow people to trade their digital assets against liquidity pools. This is different from traditional markets that use an order book to match buyers and sellers. On AMM’s users can provide their funds once deposited, they become liquidity providers (LP) and get rewarded by the DEX token (Niubi Token) and shared fees/revenues on trades.

Niubiswap Exchange

On Niubi Exchange (AMM) you can swap/trade any token in a very simple way one BEP-20 token for another via automated liquidity pools.

The liquidity provided to the exchange comes from Liquidity Providers (“LPs”) who stake their tokens in “Pools”. In exchange, they get Niubiswap Liquidity Provider tokens (NIU-LP), which can also be staked to earn Niubi tokens (NIU) in the Niubi Zone.

AMM DEX fees

When you swap tokens on Niubi Exchange, you’ll be charged a fee of 0.30%. (of which 0.17% will go to Liquidity Providers (LPs), 0.03% to Treasury, and the remaining 0.1% will be converted to NIU tokens and burned (essentially every time you traded you would be contributing to burning more Niubi tokens. Higher trading vol = Higher burn).

The fee is distributed to liquidity providers proportional to their share of the pool they choosed in Niubi Zone

When liquidity providers decide to remove their liquidity from the pool, they receive transaction fees along with their contribution to the pool, and the liquidity token they received after adding liquidity to the pool is burned.

WordsCounted: A Ruby Natural Language Processor

WordsCounted

We are all in the gutter, but some of us are looking at the stars.

-- Oscar Wilde

WordsCounted is a Ruby NLP (natural language processor). WordsCounted lets you implement powerful tokensation strategies with a very flexible tokeniser class.

Features

  • Out of the box, get the following data from any string or readable file, or URL:
    • Token count and unique token count
    • Token densities, frequencies, and lengths
    • Char count and average chars per token
    • The longest tokens and their lengths
    • The most frequent tokens and their frequencies.
  • A flexible way to exclude tokens from the tokeniser. You can pass a string, regexp, symbol, lambda, or an array of any combination of those types for powerful tokenisation strategies.
  • Pass your own regexp rules to the tokeniser if you prefer. The default regexp filters special characters but keeps hyphens and apostrophes. It also plays nicely with diacritics (UTF and unicode characters): Bayrūt is treated as ["Bayrūt"] and not ["Bayr", "ū", "t"], for example.
  • Opens and reads files. Pass in a file path or a url instead of a string.

Installation

Add this line to your application's Gemfile:

gem 'words_counted'

And then execute:

$ bundle

Or install it yourself as:

$ gem install words_counted

Usage

Pass in a string or a file path, and an optional filter and/or regexp.

counter = WordsCounted.count(
  "We are all in the gutter, but some of us are looking at the stars."
)

# Using a file
counter = WordsCounted.from_file("path/or/url/to/my/file.txt")

.count and .from_file are convenience methods that take an input, tokenise it, and return an instance of WordsCounted::Counter initialized with the tokens. The WordsCounted::Tokeniser and WordsCounted::Counter classes can be used alone, however.

API

WordsCounted

WordsCounted.count(input, options = {})

Tokenises input and initializes a WordsCounted::Counter object with the resulting tokens.

counter = WordsCounted.count("Hello Beirut!")

Accepts two options: exclude and regexp. See Excluding tokens from the analyser and Passing in a custom regexp respectively.

WordsCounted.from_file(path, options = {})

Reads and tokenises a file, and initializes a WordsCounted::Counter object with the resulting tokens.

counter = WordsCounted.from_file("hello_beirut.txt")

Accepts the same options as .count.

Tokeniser

The tokeniser allows you to tokenise text in a variety of ways. You can pass in your own rules for tokenisation, and apply a powerful filter with any combination of rules as long as they can boil down into a lambda.

Out of the box the tokeniser includes only alpha chars. Hyphenated tokens and tokens with apostrophes are considered a single token.

#tokenise([pattern: TOKEN_REGEXP, exclude: nil])

tokeniser = WordsCounted::Tokeniser.new("Hello Beirut!").tokenise

# With `exclude`
tokeniser = WordsCounted::Tokeniser.new("Hello Beirut!").tokenise(exclude: "hello")

# With `pattern`
tokeniser = WordsCounted::Tokeniser.new("I <3 Beirut!").tokenise(pattern: /[a-z]/i)

See Excluding tokens from the analyser and Passing in a custom regexp for more information.

Counter

The WordsCounted::Counter class allows you to collect various statistics from an array of tokens.

#token_count

Returns the token count of a given string.

counter.token_count #=> 15

#token_frequency

Returns a sorted (unstable) two-dimensional array where each element is a token and its frequency. The array is sorted by frequency in descending order.

counter.token_frequency

[
  ["the", 2],
  ["are", 2],
  ["we",  1],
  # ...
  ["all", 1]
]

#most_frequent_tokens

Returns a hash where each key-value pair is a token and its frequency.

counter.most_frequent_tokens

{ "are" => 2, "the" => 2 }

#token_lengths

Returns a sorted (unstable) two-dimentional array where each element contains a token and its length. The array is sorted by length in descending order.

counter.token_lengths

[
  ["looking", 7],
  ["gutter",  6],
  ["stars",   5],
  # ...
  ["in",      2]
]

#longest_tokens

Returns a hash where each key-value pair is a token and its length.

counter.longest_tokens

{ "looking" => 7 }

#token_density([ precision: 2 ])

Returns a sorted (unstable) two-dimentional array where each element contains a token and its density as a float, rounded to a precision of two. The array is sorted by density in descending order. It accepts a precision argument, which must be a float.

counter.token_density

[
  ["are",     0.13],
  ["the",     0.13],
  ["but",     0.07 ],
  # ...
  ["we",      0.07 ]
]

#char_count

Returns the char count of tokens.

counter.char_count #=> 76

#average_chars_per_token([ precision: 2 ])

Returns the average char count per token rounded to two decimal places. Accepts a precision argument which defaults to two. Precision must be a float.

counter.average_chars_per_token #=> 4

#uniq_token_count

Returns the number of unique tokens.

counter.uniq_token_count #=> 13

Excluding tokens from the tokeniser

You can exclude anything you want from the input by passing the exclude option. The exclude option accepts a variety of filters and is extremely flexible.

  1. A space-delimited string. The filter will normalise the string.
  2. A regular expression.
  3. A lambda.
  4. A symbol that names a predicate method. For example :odd?.
  5. An array of any combination of the above.
tokeniser =
  WordsCounted::Tokeniser.new(
    "Magnificent! That was magnificent, Trevor."
  )

# Using a string
tokeniser.tokenise(exclude: "was magnificent")
# => ["that", "trevor"]

# Using a regular expression
tokeniser.tokenise(exclude: /trevor/)
# => ["magnificent", "that", "was", "magnificent"]

# Using a lambda
tokeniser.tokenise(exclude: ->(t) { t.length < 4 })
# => ["magnificent", "that", "magnificent", "trevor"]

# Using symbol
tokeniser = WordsCounted::Tokeniser.new("Hello! محمد")
tokeniser.tokenise(exclude: :ascii_only?)
# => ["محمد"]

# Using an array
tokeniser = WordsCounted::Tokeniser.new(
  "Hello! اسماءنا هي محمد، كارولينا، سامي، وداني"
)
tokeniser.tokenise(
  exclude: [:ascii_only?, /محمد/, ->(t) { t.length > 6}, "و"]
)
# => ["هي", "سامي", "وداني"]

Passing in a custom regexp

The default regexp accounts for letters, hyphenated tokens, and apostrophes. This means twenty-one is treated as one token. So is Mohamad's.

/[\p{Alpha}\-']+/

You can pass your own criteria as a Ruby regular expression to split your string as desired.

For example, if you wanted to include numbers, you can override the regular expression:

counter = WordsCounted.count("Numbers 1, 2, and 3", pattern: /[\p{Alnum}\-']+/)
counter.tokens
#=> ["numbers", "1", "2", "and", "3"]

Opening and reading files

Use the from_file method to open files. from_file accepts the same options as .count. The file path can be a URL.

counter = WordsCounted.from_file("url/or/path/to/file.text")

Gotchas

A hyphen used in leu of an em or en dash will form part of the token. This affects the tokeniser algorithm.

counter = WordsCounted.count("How do you do?-you are well, I see.")
counter.token_frequency

[
  ["do",   2],
  ["how",  1],
  ["you",  1],
  ["-you", 1], # WTF, mate!
  ["are",  1],
  # ...
]

In this example -you and you are separate tokens. Also, the tokeniser does not include numbers by default. Remember that you can pass your own regular expression if the default behaviour does not fit your needs.

A note on case sensitivity

The program will normalise (downcase) all incoming strings for consistency and filters.

Roadmap

Ability to open URLs

def self.from_url
  # open url and send string here after removing html
end

The tokeniser allows you to tokenise text in a variety of ways. You can pass in your own rules for tokenisation, and apply a powerful filter with any combination of rules as long as they can boil down into a lambda.

Out of the box the tokeniser includes only alpha chars. Hyphenated tokens and tokens with apostrophes are considered a single token.

#tokenise([pattern: TOKEN_REGEXP, exclude: nil])

tokeniser = WordsCounted::Tokeniser.new("Hello Beirut!").tokenise

# With `exclude`
tokeniser = WordsCounted::Tokeniser.new("Hello Beirut!").tokenise(exclude: "hello")

# With `pattern`
tokeniser = WordsCounted::Tokeniser.new("I <3 Beirut!").tokenise(pattern: /[a-z]/i)

See Excluding tokens from the analyser and Passing in a custom regexp for more information.

Counter

The WordsCounted::Counter class allows you to collect various statistics from an array of tokens.

#token_count

Returns the token count of a given string.

counter.token_count #=> 15

#token_frequency

Returns a sorted (unstable) two-dimensional array where each element is a token and its frequency. The array is sorted by frequency in descending order.

counter.token_frequency

[
  ["the", 2],
  ["are", 2],
  ["we",  1],
  # ...
  ["all", 1]
]

#most_frequent_tokens

Returns a hash where each key-value pair is a token and its frequency.

counter.most_frequent_tokens

{ "are" => 2, "the" => 2 }

#token_lengths

Returns a sorted (unstable) two-dimentional array where each element contains a token and its length. The array is sorted by length in descending order.

counter.token_lengths

[
  ["looking", 7],
  ["gutter",  6],
  ["stars",   5],
  # ...
  ["in",      2]
]

#longest_tokens

Returns a hash where each key-value pair is a token and its length.

counter.longest_tokens

{ "looking" => 7 }

#token_density([ precision: 2 ])

Returns a sorted (unstable) two-dimentional array where each element contains a token and its density as a float, rounded to a precision of two. The array is sorted by density in descending order. It accepts a precision argument, which must be a float.

counter.token_density

[
  ["are",     0.13],
  ["the",     0.13],
  ["but",     0.07 ],
  # ...
  ["we",      0.07 ]
]

#char_count

Returns the char count of tokens.

counter.char_count #=> 76

#average_chars_per_token([ precision: 2 ])

Returns the average char count per token rounded to two decimal places. Accepts a precision argument which defaults to two. Precision must be a float.

counter.average_chars_per_token #=> 4

#uniq_token_count

Returns the number of unique tokens.

counter.uniq_token_count #=> 13

Excluding tokens from the tokeniser

You can exclude anything you want from the input by passing the exclude option. The exclude option accepts a variety of filters and is extremely flexible.

  1. A space-delimited string. The filter will normalise the string.
  2. A regular expression.
  3. A lambda.
  4. A symbol that names a predicate method. For example :odd?.
  5. An array of any combination of the above.
tokeniser =
  WordsCounted::Tokeniser.new(
    "Magnificent! That was magnificent, Trevor."
  )

# Using a string
tokeniser.tokenise(exclude: "was magnificent")
# => ["that", "trevor"]

# Using a regular expression
tokeniser.tokenise(exclude: /trevor/)
# => ["magnificent", "that", "was", "magnificent"]

# Using a lambda
tokeniser.tokenise(exclude: ->(t) { t.length < 4 })
# => ["magnificent", "that", "magnificent", "trevor"]

# Using symbol
tokeniser = WordsCounted::Tokeniser.new("Hello! محمد")
tokeniser.tokenise(exclude: :ascii_only?)
# => ["محمد"]

# Using an array
tokeniser = WordsCounted::Tokeniser.new(
  "Hello! اسماءنا هي محمد، كارولينا، سامي، وداني"
)
tokeniser.tokenise(
  exclude: [:ascii_only?, /محمد/, ->(t) { t.length > 6}, "و"]
)
# => ["هي", "سامي", "وداني"]

Passing in a custom regexp

The default regexp accounts for letters, hyphenated tokens, and apostrophes. This means twenty-one is treated as one token. So is Mohamad's.

/[\p{Alpha}\-']+/

You can pass your own criteria as a Ruby regular expression to split your string as desired.

For example, if you wanted to include numbers, you can override the regular expression:

counter = WordsCounted.count("Numbers 1, 2, and 3", pattern: /[\p{Alnum}\-']+/)
counter.tokens
#=> ["numbers", "1", "2", "and", "3"]

Opening and reading files

Use the from_file method to open files. from_file accepts the same options as .count. The file path can be a URL.

counter = WordsCounted.from_file("url/or/path/to/file.text")

Gotchas

A hyphen used in leu of an em or en dash will form part of the token. This affects the tokeniser algorithm.

counter = WordsCounted.count("How do you do?-you are well, I see.")
counter.token_frequency

[
  ["do",   2],
  ["how",  1],
  ["you",  1],
  ["-you", 1], # WTF, mate!
  ["are",  1],
  # ...
]

In this example -you and you are separate tokens. Also, the tokeniser does not include numbers by default. Remember that you can pass your own regular expression if the default behaviour does not fit your needs.

A note on case sensitivity

The program will normalise (downcase) all incoming strings for consistency and filters.

Roadmap

Ability to open URLs

def self.from_url
  # open url and send string here after removing html

SafeMoon Clone | Create A DeFi Token Like SafeMoon | DeFi token like SafeMoon

SafeMoon is a decentralized finance (DeFi) token. This token consists of RFI tokenomics and auto-liquidity generating protocol. A DeFi token like SafeMoon has reached the mainstream standards under the Binance Smart Chain. Its success and popularity have been immense, thus, making the majority of the business firms adopt this style of cryptocurrency as an alternative.

A DeFi token like SafeMoon is almost similar to the other crypto-token, but the only difference being that it charges a 10% transaction fee from the users who sell their tokens, in which 5% of the fee is distributed to the remaining SafeMoon owners. This feature rewards the owners for holding onto their tokens.
