Data archive request: Columbus-5 historical blockstore (blocks 4,724,001 → 7,607,789) #662

Context

I'm building an academic dataset for a tracking-error and depeg-mechanics
study covering DAI, Synthetix synths and TerraUSD as canonical stablecoin
case studies. The UST chapter requires minute-resolution on-chain data
across the Columbus-5 window — block range 4,724,001 (30 Sept 2021) →
7,607,789 (12 May 2022 first chain halt)
.

What I'm looking for

A tar of an archival blockstore + state (the data/ directory of a
classic-terra/core node that fully synced from Columbus-5 genesis with
pruning disabled). Approximate size: 500-800 GB compressed. I'd mount it
locally, expose LCD, and run my own indexers for:

  • market/MsgSwap events (UST↔LUNA mint/burn through the algorithmic module)
  • bank supply snapshots (uusd denom, daily resolution)
  • oracle exchange rate votes
  • wasm execute messages filtered on Anchor, TerraSwap, Astroport contracts

What I've already checked (none works for this window)

  • columbus-genesis.s3.ap-northeast-1.amazonaws.com — stops at
    columbus-4-data.tar.lz4 (Jan 2022), no Columbus-5 dump available
  • Hexxagon snapshots — only pruned recent state (e.g.
    snapshot-goleveldb-28556994.tar.lz4, ~89 GB, recent height)
  • PublicNode / Polkachu / Quicksync / NowNodes — earliest_block in
    the high-20M range (April 2026 onwards), all pruned
  • Flipside Crypto — Terra support discontinued 2025-07-01, repo
    FlipsideCrypto/terra-models removed
  • Dune / Allium / Numia / The Graph — no Terra Classic indexing
  • Resync from Columbus-5 genesis — blocked by the absence of an
    archival P2P peer serving historical blocks

What I can offer

  • Acknowledgement in the resulting academic publication
  • Open-sourced parquet output and indexing code once the analysis lands
