About this project

What does Polis add?

The code is a notary and an archive, never a judge

Polis does not stop you from lying, stealing or killing. It records the
obligation with its signatures, watches the terms it can verify objectively,
and publishes the outcome to everyone, permanently.

Breaking a contract is always possible. It is just never quiet, and never free.

Contracts

Two kinds of term, and the distinction is the whole design:

  • Tracked — a delivery or a non-aggression pact. A missed deadline or a
    struck ally is an objective fact, judged by the code and announced.
  • Untracked — a promise. The mod records the words and the parties and
    stays out of the verdict. The party it was made to may bring it to a bench,
    which answers the one question a machine never could: was it kept.

Land, borders and roads

Claim ground, name it, set a charter. A closed border shows a warning and a
wall you can walk through — theft is counted, not blocked. Every act on ground
that has a holder goes into that holder's day-book: what was broken, what was
carried out of which container, who was killed.

Roads can be priced. A toll meter runs while you travel and settles at the end
of the journey, not on a total, so a drive is one line in your statement rather
than a hundred.

A court, with a real hearing

A complaint is filed, the accused may answer, and a bench of elected judges
votes. A finding cannot be made on the day it is asked for: the hearing lasts a
day, so nobody is sentenced while they are asleep. The running tally is sealed
while the bench sits. The fine reaches the person who was wronged, and only the
shortfall becomes time.

A market that settles

A global order book with escrow. Placing an order locks the goods or the coin
at once, so a matched trade can never fail to settle. The seller names the
price; a bid is a ceiling, never a quote. Commerce is mechanical; politics
stays social.

Money that is a currency

Coin enters the world only by mining, and is minted at a counter whose rate
falls in published steps as coin per person rises. The market burns one coin in
fifty of a settled trade. There is a source, a drain, and a number between
them.

The map

The neighbourhood drawn on the register: who holds what, which ground is in
reach to claim, where a border runs, and where you were robbed while you were
away — a question a client-side map cannot answer at all. It searches holders,
named places and your own marks.

Requirements

  • Minecraft 1.21.1, NeoForge 21.1.248
  • Required on both the client and the server
  • Press P in game

English and Українська, switched with the normal Minecraft language setting.
The server never sends finished text — every event carries a translation key,
so two players read the same event each in their own language.
