Disc Minat — mined storage

OmbraChain has a fully on-chain filesystem, and its economics are unusual: you don't buy storage, you mine it. Winning a block grants storage capacity that accumulates on your account forever.

On OmbraChain you don't buy storage — you mine it. Each block you win grants 4096 B of capacity that accumulates forever. Files occupy it; deleting reclaims it.

Blocks won: 50
Disk used: 40%
used 80.0 KBfree 120.0 KBcapacity 200.0 KB

At ~1 block / 15s, a solo miner earns ≈ 22.50 MB / day. Capacity is also transferable (a storage market).

How it works​

  • Earn: each block you win credits your account with STORAGE_QUOTA_PER_BLOCK = 4096 bytes of capacity. It accumulates.
  • Spend: writing a file consumes capacity (used + size ≤ capacity) — no OMBRA fee, you spend mined bytes.
  • Reclaim: the disk is a real disk — deleting a file frees its bytes again.
  • Trade: capacity is transferable. A STORAGE_TRANSFER moves free bytes to another account, so non-miners can buy disk from miners — a storage market backed by real work.

This is content-addressed under the hood (the same machinery that powers on-chain websites). The total stored data can't grow faster than the mining rate, which keeps the chain light.

The filesystem​

Your files form a versioned tree owned by your ox address (your "parcel"):

  • Working copy lives locally (instant edits).
  • Commit publishes a new immutable version (content-addressed; unchanged files are deduped for free).
  • Checkout restores any past version — full history, time-travel.

Account storage fields are exposed by the API:

GET /api/wallet/balance/ox7a8b…
{ "balance": "…", "storageCapacity": "45056", "storageUsed": "12288", "storageFree": "32768" }
