Background

A network for everyone

Why this network exists, how it is built, and how it compares to what already exists.

The first cryptocurrencies promised that anyone could take part. Paritr is an attempt to keep that promise workable.

The motivation

When Bitcoin launched, mining ran on ordinary computers. Within a few years that was over: purpose-built chips arrived, then warehouses full of them. Today a handful of industrial operations produce most new coins, and an individual with a laptop has no realistic path in.

That is not a moral failing of anyone involved - it is the predictable result of a puzzle that rewards raw silicon. If you want participation to stay open, the puzzle itself has to be chosen differently. That is the whole idea behind Paritr.

How it is built

Paritr follows Bitcoin’s architecture closely: an 80-byte block header, a Merkle tree over the transactions, compact difficulty encoding, most-work-chain consensus. What differs are two deliberate decisions, described below.

The two decisions

What actually makes the difference

memory

A memory-hard puzzle

Instead of SHA-256 the proof of work uses scrypt with a 2 MiB scratchpad per hash. The cost is dominated by memory latency rather than gate count, which removes most of the advantage specialised hardware would otherwise have. It is the same footprint that kept ASICs away from CryptoNight for years.

Rewards by proven work

Small miners normally need a pool operator to be paid regularly. Paritr builds that sharing into consensus itself: 95 % of each block reward is split by the share of proven work over the last 120 blocks. No pool, no operator, no fee - and no single point of control.

In context

How Paritr compares

Bitcoin and Monero are the obvious reference points: one defined the field, the other has fought the hardest to keep mining on general-purpose CPUs.

Bitcoin Monero Paritr
Proof of work SHA-256d RandomX scrypt (2 MiB)
Realistic hardware ASIC only CPU CPU
Payout for small miners External pool External pool Built into consensus
Block time ~10 min ~2 min 60 s
Supply 21 Mio. Tail emission Tail emission
Solo setup effort Not viable Moderate One command

Bitcoin and Monero are mature networks with enormous security budgets and years of adversarial testing. Paritr is young and makes no claim to match that - the table compares design choices, not track records.

What Paritr is not

Paritr is not an investment product and makes no promise about value. It is infrastructure: a ledger, a currency, and the tools to use them.

It is also young software. Coins may lose all value, transactions cannot be reversed, and a lost key cannot be recovered by anyone. Use it with that clearly in mind.

The name

Paritr comes from the Latin pariter - equally, on equal footing.
