Min: Crypto Token for Beautiful and Secure Code

Min is a new programming language for beautiful and secure code. We issue crypto tokens to investors and developers for bootstrapping the network in open source and governance.

Token networks align participants toward a common goal. Our mission is to build a profitable and sustainable ecosystem of good software.

Below are an introduction to Min the language and a walkthrough of our source code.

Consensus and Incentives

Contributors earn Min coins, denoted by the infimum symbol ∧, through technical work, community building, or business development. Examples include

  • ∧100: Write blogs, documentation, crash reports;
  • ∧1,000: Port libraries, hunt bounties, moderate Slack; and,
  • ∧10,000: Port to iOS / Android / Ethereal VM, launch token sales.

Min solves the most pressing problems of large-scale software development: hiring and collaboration. With Min tokens, decentralized work is rewarded with smart contracts. With Min language, code evolution is guided by strong types.

Our first product is a cross-platform framework for native mobile applications. Soon we will also optimize for machine learning and decentralized applications. Sign up for news of our token launch!

100x and Roadmap

Currently Min compiles to x86-64 machine code without any external tools. Self-contained for cross compilation and consistent on any platform, Min does not use any C backends, assembly, or linker.

  • Self-compile without any tools on Mac OS X
  • Port to Linux, iOS, Android, Javascript, Windows
  • Generalized sequences, memory management
  • Coding guide, language specification
$ make
./min binary `cat packs` 3< > min1
chmod +x min1
./min1 binary `cat packs` 3< > min2
[[ `md5 < min1` == `md5 < min2` ]]

Charm and Delight

Min is the most innovative programming language designed for beautiful code. To create it, we have started from scratch with machine code, then re-thought every syntax and idiom.

Beautiful code, like mathematics, is pleasurable to learn and to write. With Min, immutability by default simplifies stateful computations. Rich, advanced types eliminate mistakes and guide optimizations.

The art of programming — with the right syntax.

Minimalist syntax Immutable data Advanced types
orthogonal yet intuitive think in mathematics automatically bug-free

Philosophy. Yearn for the vast and endless Bits.

hex1 x:C : N = \a <= x <= \f & x - \a + 10 | x - \0
Fact (hex1 \d == 13)

hex s:S n=0 : N = s.0 & hex s+1 16n+s.0.hex1 | n
Fact (hex 'cafebabe' == 3405691582)

To code, don't drum up the men to use frameworks and design patterns. Instead, teach them to yearn for elegant algorithms in beautiful syntax. Min's novel parser uses horizontal spacing and vertical layout to free programming from clutters of delimiters and LALR(1) grammars. Here, zero keywords and all operators are of a single keyboard character except the four relational operators.

builtin keywords delimiters with layout composite operators
0 0 4

Purpose. Fun for Thinkers and Tinkers.

Everyone can be taught to code but thinkers dream of abstractions and tinkers obsess with implementations. Min's design emphasizes the unifying foundation of higher-order functions and formal types. This means flow controls and generic sequences are naturally user-definable. You can think in terms of mathematical logic, and write as such.

hash_get rows:0/1 x:0 : 1 = rows 
 . hash x % size rows
 / y? x == y
 . head
Fact (hash_get ['foo'?13, 'bar'?42] 'bar' == 42)

All the while, you can peek behind every piece of Min's code — no dragons of macros or generated C code ahead. Tinker and master the intricate clockwork of our compiler in a unified language, from machine registers as well as database backends, all the way to web frontends and decentralized applications.

items = Sql ''
 . join users on=(x? u? x.user ==
 / x? x.status != Done
 . top 5

done id:N = Xhr async=1 '/done?[id]'
  Title Top [items.size] TODO
  items * id,summary,time,name?
    Li onclick=done(id) [summary], [time] by [name]
Infinite model Unified web
strings, files, tables as lazy sequence SQL, HTML, Javascript in one syntax

Technology. Need for Speed and Security.

In “Computer Scientists Close In On Perfect, Hack-Proof Code,” Kevin Hartnett at Quanta Magazine writes:

Key parts of Little Bird’s computer system were unhackable with existing technology, its code as trustworthy as a mathematical proof... That results made all of Darpa stand up and say, oh my goodness, we can actually use this technology in systems we care about.

Previously, when computers were isolated in homes and offices, programming bugs were merely inconvenient. Now those same small coding errors open massive security vulnerabilities on networked machines that allow anyone with the know-how free rein inside a computer system.

Memory management costs enormous development effort or it dominates runtime cycles. Min's innovative type inference automates ownership annotations in a region-based memory model, so code remains at a high-level abstraction without the complexity of a garbage collector.

Term = Tag
 Apply fun:Term arg:Term
 If test:Term pos:Term neg:Term
 Binary left:Term op:S right:Term

rewrite : Term? Term =
  Binary (Binary a '&' b) '|' c? If a b c    
  Binary a '&' b? If a b Nil
  Binary a '.' b? Apply b a
  Binary a '@' b? Binary b ';' a

Min's precise types also guarantee correctness before execution and optimize for machine performance. Scaling to a million page requests or intensive scientific computations won't need delegating to foreign functions. With Min, you won't have to worry about null pointers in critical services, or stealing and tampering of your digital assets in decentralized applications.

 s : ℝ # stock price
 x : ℝ # strike price
 t : ℝ # expiration time in years
 r : ℝ # risk-free interest rate
 σ : ℝ # volatility
 : ℝ
 = s ϕ(d1) - x e^(-r t)ϕ(d2) @ 
  ϕ = Normal.cdf
  d0 = log s/x + (r + σ²/2)t
  d1 = d0 / σ√t
  d2 = d1 - σ√t

Hungry and Foolish

Join our mailing list and Slack to build the future!

I learned about serif and sans serif typefaces, about varying the amount of space between different letter combinations, about what makes great typography great. It was beautiful, historical, artistically subtle in a way that science can't capture, and I found it fascinating... It was the first computer with beautiful typography.
