In active development — core pricing engine implemented on Bitcoin Core

Bitcoin Tolerant

We don't judge your data. We charge what the block space actually costs.

Built directly on Bitcoin Core. No filtering. No hidden subsidy.

The problem

A discount for signatures, used for files.

In 2017, Bitcoin gave witness data a 75% discount, designed for signatures. Since 2023, that same discount is used to store arbitrary files for a quarter of the price everyone else pays for the same block space.

Witness byte1 WU
75% off — same block space
The formula

Three lines. No content judgment.

reference_rate = recent block fees / recent block vbytes
economic_vbytes= base_bytes + data_bytes × premium
required_fee   = economic_vbytes × reference_rate

Monetary bytes are never multiplied. Sending money never costs extra.

Live pricing

The same 50 KB image, in three markets.

Always the same — Tolerant never overcharges money, no matter the market.
Limits

What it never does.

  • Never rejects a valid block
  • Never changes chain selection
  • Never filters by content — only by cost
  • Never charges more when there's no demand
  • Never enforces BIP-110 or any consensus rule
