Frostbyte Start freezing
decentralized cold-data archival

The deep freeze for data you keep but rarely touch.

Hot storage bills you to keep cat videos warm forever. Frostbyte takes the bytes you only need someday — backups, raw footage, compliance logs, the cold tail of your data lake — and seals them in a crystalline, geo-scattered archive at a price that finally makes "keep everything" rational.

How cold storage works at Frostbyte

Cold data wants to be cheap and durable, not fast. We trade milliseconds for months of price, then make the trade invisible.

  1. 1

    Shatter & scatter

    Each object is erasure-coded into 6 shards using Reed–Solomon (4 data + 2 parity). Any 4 shards rebuild the file, so two whole regions can melt and your bytes survive.

  2. 2

    Crystallize

    Shards are sealed into immutable frost blocks, content-addressed by BLAKE3, and pinned to cold nodes — spun-down disk and tape, paid to sit still in cold climates.

  3. 3

    Deep freeze

    Once 4-of-6 shards confirm, the object is frost-sealed: write-once, fee-locked, and proven on-chain every epoch with a Merkle frost-proof. No silent bit-rot.

  4. 4

    Thaw on demand

    Call thaw() and we re-warm the nearest 4 shards in parallel. First byte in minutes; the rest streams while it rehydrates. Pay only for what you pull back.

02 — pricing

Cold tiers, colder prices

The colder the tier, the longer the thaw — and the lower the bill. Storage is billed per TB·month; retrieval is billed only when you thaw.

Freeze & thaw in four lines

One small client. Stream in, get back a frost-proof CID, thaw whenever you like.

pythonnodecli
from frostbyte import Vault

vault = Vault(tier="glacier")

# write-once, frost-sealed, content-addressed
proof = vault.freeze("vault-2026/raw-cam03.mxf")
print(proof.cid)   # bafyfrost…q7x · sealed in 6 shards

# months later — rehydrate on demand
stream = vault.thaw(proof.cid)        # first byte ~4 min
for chunk in stream:
    out.write(chunk)
  • Idempotent freezes. Re-freezing the same content returns the same CID — no double billing, no duplicate shards.
  • Resumable thaws. Streams carry byte-range cursors; a dropped connection picks up where it left off.
  • S3-compatible gateway. Point an existing backup tool at s3.frostbytelabs.xyz and the cold tail just gets cheaper.
  • Verifiable. Every object ships a frost-proof you can check against the chain without trusting us.

What customers keep on ice

"We had 9 PB of raw drone footage rotting on hot S3. Moving the cold tail to Frostbyte's Permafrost tier cut that line item by 91%. We haven't thought about it since."
Priya AnandHead of Infra, Terrascan Aerial
"Seven-year retention is a regulation, not a wish. The on-chain frost-proofs mean our auditors verify the archive themselves instead of taking our word for it."
Marcus VogelCISO, Norby Financial
"Thaw was the part I was scared of. First byte came back in four minutes and the rest streamed while my pipeline ran. Cold doesn't have to mean slow-to-start."
Dana OkaforStaff Engineer, Loomframe
