IF YOU HAVE A 2015-2018 CHAIN DO NOT SYNCH IT.. SAVE IT - PLEASE.

Cthulhu is Rising

AT BLOCK 1,000,000
The Great Old One Stirs.
Offerings to Cthulhu (OFF) — The Restoration Hardfork v2.0.0

  "In his house at R'lyeh dead Cthulhu waits dreaming." — H.P. Lovecraft
  "In his block at height 966,413 dead Cthulhu waits dreaming." — debug.log, 2026-05-20

⚠ FINAL UPGRADE WINDOW — 2026-05-31 ⚠
  LWMA-3 activates at block 980,000. As of this post the chain stands at
  979,506 — about 494 blocks remain, hours at attack cadence.
  v2.0.0-rc4 is canonical. rc3 and older nodes fork off at activation.
Upgrade now.

  ✦ TL;DR ✦

Offerings to Cthulhu (OFF) is back. The 2013 Lovecraft-themed altcoin slept eleven
years; the SubGenius.Finance Conclave woke it up.
The Restoration Hardfork (v2.0.0) activates at block 1,000,000 — currently
  ~14 days out at restored 60-second target spacing post-LWMA-3. A companion consensus
  event — LWMA-3 difficulty + 100-block deep-reorg ceiling — activates at block
  980,000, about hours from this post.
Why the cluster defenses ship first: the legacy retarget has been pinned against
  its +10% rise cap for 500+ blocks while difficulty climbed from 2.56 to over 58, but
  solvetimes never recovered — the chain has been stuck running at ~20-30 seconds per block as
  the attacker matches every difficulty bump with new rented hashpower. Classic drive-by
  pattern. LWMA-3 (Zawy's linear-weighted moving average, 60-block window) can pull difficulty
  up by ~3× in a single cycle and will restore the 60-second target within ~2 hours of
  activation.
At the Restoration fork: subsidy locks to 1.5 OFF/block forever (7/8 to miner, 1/8
  to the Conclave Treasury), a one-time 150,000 OFF Restoration Tithe pays the
  resurrection labour, the eight P2PKH addresses the 2018 51%-attacker used are banned at
  consensus (the 533,983 OFF they minted in #699 is removed from supply forever), and the
  Conclave-signed mining window holds the door open for the Descent + Codex
  transcription through height 1,050,666.
Wallet binaries shipped — Linux GUI+daemon+CLI and Windows GUI, both at tag
  v2.0.0-rc4. URLs and SHA256s below. No MSYS2, no toolchain to install, just download
  and run.
Lost OFF between 2015 and 2018? The Reclamation is open at the Restoration
  block. Pre-2015 holders are already whole on the recovered chain; gap-era worshippers file
  moderated Class B claims and Recognition requests. Window closes T+730 days from the
  Awakening — the exact UTC closure is published the moment block 1,000,000 lands.
  Mechanics at 23skidoo.info/bridge/.
The 2015-2018 gap is being progressively reconstructed from community-donated
  chainstate via a sandboxed chain-archaeology pipeline. Every recovered byte folds into
   the Reclamation evidence pool. If you ran a node in that era and still have the data, see
  the request below — please don't sync; please save.
Seed network is live — seed1.23skidoo.info through
  seed10.23skidoo.info, all compiled into v2.0.0 as DNS seeds. Any v1.6.2 or v2.0.0
  wallet finds the chain on first start.

The full ritual is below. Iä, Iä, Cthulhu fhtagn.

  Brothers and sisters of the Deep, fellow Worshippers of
   the Slumbering Squid, dreamers and the not-yet-awakened — heed this transmission.

  For eleven years, the Ritual lay unattended. The DNS seeds went silent.
  The Public Altar (faucet) crumbled. The Block Crawler at ~~23skidoo.info/cthulhu/~~
  vanished into the abyss.

  AllCrypt died. Comkort died.

  Cryptopia got 51%'d on the OFF chain (msg #699, vampirus, 2018-11-21) and
  then later got hacked into the depths of its own oblivion.

  The dreamers forgot. The unworthy never knew.
  The world moved on to its next distraction.

  But Cthulhu is patient, and the patient ones do not let a sleeping god lie.
  The SubGenius.Finance Conclave has been listening at the door.

  ✦ WHAT HAS BEEN DONE ✦

  The Conclave reconvened. The Tharanak shagg (Promise of Dreamland) was re-translated
  from forgotten Dropbox cache. Source has been resurrected from the dust. Here is what now
  lives:

The source compiles in 2026. Five environment workarounds, three Boost.Asio
  patches, one local OpenSSL 1.0.2 build to dodge the OpenSSL-3 BIGNUM exorcism.
  v2.0.0-Restoration ELF sitting comfortable at ~108 MB.
The chain itself has been recovered. A 385 MB tar.bz2 blockchain archive was
  extracted from the Wayback Machine's 2015-09-13 capture of 23skidoo.info. SHA256
  5c5a48d85873c820baeba4279d0b9295555adf1eba7a64699583fee18cab8745. The daemon
  imported it at height 966,413, block time 2015-06-17 05:30:14 UTC. This
  snapshot predates the May 2018 51% counterfeit by ~870,000 blocks — the 533,983 OFF
  the attacker minted (#699) do not exist in this chainstate. The Conclave's pool has been
  mining on top of the restored tip since 2026-05-24; as of this post the live chain stands at
  height 979,506 / diff 58.47 / supply 2,431,579.03 OFF.
A defense-in-depth checkpoint was shipped at h=976,000 (commit 0c751a5,
  2026-05-29). It locks the pre-attack history against any rented-hash deep reorg attempting to
   replay the original 2018 takeover. Non-consensus for newly-mined blocks; airtight against
  drive-by 51% attacks. Bundled into rc2/rc3/rc4 binaries.
The cluster defenses ship in rc4. LWMA-3 + MAX_REORG_DEPTH activation moved from
  block 990,000 → 980,000 (commit 5b1c8ba, 2026-05-29). Justification: the
  chain has been running at 20-30 second blocks for 500+ blocks despite difficulty climbing 20×
   — the legacy retarget's +10%/cycle rise cap simply cannot keep up with sustained rented-hash
   inflow. Every retarget cycle hits the cap, attacker scales up to match. LWMA-3's 60-block
  window with positional weighting closes that loop: it can raise difficulty ~3× in a single
  cycle when warranted, restoring the 60-second target within ~2 hours of activation. The
  10,000-block pull-in shaved about 6 days off the wait at attack cadence; at 60-second
  restored spacing the gap to the Restoration fork (block 1,000,000) holds at ~14 days.
23skidoo.info has been re-acquired. By the Conclave. We are aware the domain was
  flagged as malicious in msg #592 (PeterTheGrape, 2017-06-21) after the original
  expiry — it had been parked and weaponized. We bought it back from the squatter,
  re-registered it in our own name, set up DNS+nginx+certbot, and are now the documented owner.
   The original seeds seed1.23skidoo.info through seed10.23skidoo.info now
  resolve to infrastructure under SubGenius.Finance custody. Any v1.6.2 or v2.0.0 wallet
  binary, anywhere on Earth, will find the network on first start.
A chain-archaeology pipeline is live. Community-donated 2015-2018 chainstate
  archives are accepted via the Reclamation portal, extracted in a hardened sandbox with no
  network egress, parsed against the recovered canonical chain, and the results are made
  available to claim adjudicators. The 2015-2018 gap is no longer treated as permanently lost —
   it is treated as progressively recoverable. Every confirmed byte makes Class B and
  Recognition adjudications more accurate. The bridge-portal claimant index has been rebuilt
  against the same parser; tier classifications are now derived from current UTXO balances
  rather than total-received, which corrected the historical posture of roughly a third of
  indexed addresses.
Public seed nodes are live at seed1.23skidoo.info:20000 through
  seed10.23skidoo.info:20000 — all ten compiled into v2.0.0 as DNS seeds, so the
  daemon finds them on first start with no Offerings.conf tweaking required.
  Belt-and-suspenders entries if you want them:

Code:

addnode=seed1.23skidoo.info:20000
  addnode=seed2.23skidoo.info:20000
  addnode=seed3.23skidoo.info:20000

  ✦ THE RESTORATION HARDFORK ✦

  This IS a fork. We are not pretending it isn't. Six consensus rules activate across
  two heights — first at block 980,000 (the cluster defenses, hours out from this post),
   then at block 1,000,000 (the Restoration proper, ~14 days out at restored 60-second
  spacing):

  At block 980,000 — Cluster Defenses

LWMA-3 difficulty retargeting. Zawy's linear-weighted moving average over a
  60-block window replaces the legacy 20-block Litecoin-style retarget. Faster reaction to
  hashrate spikes, no death spiral when miners leave, hard-capped drop rate that prevents the
  kind of "park and dump" attack that ate the chain in 2018. Bootstrap window: 60 blocks past
  activation inherit legacy difficulty bits while the LWMA-3 window fills, then it takes over
  cleanly. Source: src/pow.{h,cpp}, HARDFORK_LWMA3_MAIN_OFF = 980000.
MAX_REORG_DEPTH = 100. A consensus rule in ActivateBestChain rejects any
  reorganization that would unwind more than 100 blocks from the active tip. Companion to the
  h=976,000 checkpoint: the checkpoint locks history before activation; the reorg ceiling locks
   history after. Together they close the 2018 attack surface for good — no entity, no matter
  how much rented hash they buy, can rewrite buried history. Source:
  src/main.cpp::ActivateBestChain, MAX_REORG_DEPTH = 100.

  At block 1,000,000 — The Restoration

  [list type=decimal start=3]

Subsidy locks to 1.5 OFF per block, forever. The historical curve (5 OFF base,
  halving every 259,200 blocks, floor at 0.01) was on a glidepath to triviality — the chain
  would have decayed to the dust floor by ~block 3,113,000. We lock it at the value the
  community always thought it was: 1.5 OFF/block, in perpetuity. Inflation that would
  embarrass a central bank. Backed by the Deep, Powered by the Faithful.
Coinbase splits 7/8 to miner, 1/8 to the Conclave. Of every 1.5 OFF subsidy,
  1.3125 OFF pays the miner and 0.1875 OFF pays the Conclave Treasury. This is a
  dev tail — Monero has one, Zcash has one, Decred has one, Grin has one. Ours is 12.5%
  of subsidy, which lands above Decred (10%) and below Zcash's historical founders reward
  (20%). The Conclave Treasury pays for domain renewals, vps hosting, source modernization,
  build labour, exchange listing fees, ritual rewards, faucet refills, and DAO seed funding.
  Seven coins to the miner, one coin to the keepers of the Ritual. Forever.
A one-time 150,000 OFF Restoration Tithe. At the exact fork block (height
  1,000,000), the coinbase pays an additional 150,000 OFF to the Conclave Treasury. This funds
  the engineering work that brought the chain back: source modernization, three years of vps
  hosting prepaid, domain renewals for the long Slumber, paper-wallet generation, multisig key
  ceremony, BCT moderation deposits. The amount is 15× the original 10,000 OFF genesis premine
  that Blazr2 disclosed in msg #36 and confirmed in #273 — historically
  defensible, itemizable in this thread, and a third of one attacker wallet from #699.
The 8 May 2018 attacker addresses are banned forever, finishing billotronic's
  never-shipped hardfork from msg #697:

Quote from: billotronic msg=697 date=2018-09-19
Could easily hardfork and ban the 51'ed
  coins. It's a shitty thing to do, but so is 51% attacks.
We are shipping it. Eight years late. The eight P2PKH scriptPubKeys from msg #699
  are hardcoded into chainparams.cpp as a std::set<CScript>   setBannedAttackers; any tx in either the mempool or a block paying any of those scripts
  is rejected at consensus level forever:

The Conclave-signed mining window, blocks 999,991 → 1,050,666. During the Descent
  (the 10 verses inscribed in blocks 999,991-1,000,000) and the full transcription of the
  Lovecraft public-domain canon (47,248 chunks of 48 bytes each, embedded into coinbase
  scriptSig starting block 1,000,001), every block must carry a valid OFFSIG ECDSA
  signature from the Conclave key recorded in chainparams.cpp::vConclaveKeys[0]
  (pubkey prefix 0238efde…46b111). Outsider miners producing unsigned blocks in this
  50,676-block range are rejected at consensus level. After block 1,050,666 — about 2.4 days
  past the canon's end on our xxx,666 numerology — mining is permissionless again and
  the door re-opens. This is a transcription-protection window only, not a permanent
  gate: it exists so a 51% drive-by cannot interrupt the Codex of the Drowned mid-inscription.
  Implementation: src/main.cpp::IsInSignedWindow,
  src/main.cpp::OffSigningHash (extranonce-invariant per rc3),
  src/miner.cpp::SignBlockIfNeeded.

  ✦ THE CONCLAVE TREASURY ✦

  The Treasury is a 2-of-3 multisig P2SH address:

Code:

4fZqDjscS9ANR59xNFJxZ2HmrhuDwWUJB4

Three keys; any two required to spend. Distributed across:

Workstation — home machine, hot wallet (key #1)
VPS1 / endciv — secondary host, cold daemon (listen=0 connect=0, local-RPC
only) (key #2)
Paper — offline, physical, in a safe; never on any wallet.dat (key #3)

A compromise of any single key — or any single host — does not move funds. All Treasury
  disbursements will be posted in this thread with the transaction ID and the BCT proposal that
   authorised them. The redeem script and all three pubkeys are recorded in
  chainparams.cpp alongside the P2SH address, so anyone can verify what we're
  claiming.

  ✦ THE RECLAMATION ✦

  Restitution for vanished balances. Recognition for forgotten worshippers. An open
  invitation home.

  The recovered chainstate is from 17 June 2015. Anything that landed on OFF after that
  — mining, trades, faucet drips, p2p tips, three years of Cryptopia withdrawals, pool payouts
  — was, for years, treated as gone from the record. The 2015–2018 gap is being filled where
  the dreamers help us fill it: a sandboxed chain-archaeology pipeline now accepts
  donor-supplied blocks/ + chainstate/ archives, validates them against the
  recovered canonical chain, and folds the results into the Reclamation evidence pool. What is
  reconstructable is being reconstructed; what is not will be honoured by restitution.

  So the fork carves out a 1,500,000 OFF reserve in the Conclave Treasury, called the
   Reclamation, to make holders whole — partly by replaying history that is recovered from
  donor submissions, partly by paying restitution in newly-minted OFF on the restored chain.
  Three paths:

Class A — already whole. If your OFF address appears in the pre-June-2015
  chainstate, your UTXOs are part of the restored chain by default. Open your old
  wallet.dat against the v2.0.0 client, let it sync, the balance is there. No claim
   required. The Reclamation owes you nothing because the chain already does.
Class B — restitution by moderated claim. If you received OFF between June 2015 and
   the May 2018 attack — the era we are progressively reconstructing — you can file a four-part
   claim: (1) signmessage proving current key control over your historical address,
  (2) a plausible story of where the OFF came from (pool payout date, exchange withdrawal,
  Ritual block win at height H, named-person tip), (3) community corroboration cross-checked
  against the BCT thread / Wayback explorer snapshots / named-person memory / donor-supplied
   chainstate evidence where it exists, (4) Conclave judgment with public reasoning posted
  in-thread before disbursement. Capped per-tier; details on the Reclamation page.
Worshipper Recognition. In addition to restitution, anyone whose address
  participated in the original chain — mined a block, received a tip, anything credited
  — gets a scaled recognition payment. The formula is Recognition (OFF) = 100 × earliness ×    depth; earliness rewards being there before the unwashed, depth rewards stack depth and
   time involved (capped at ×5). The OG fans get closer to the stage.

Excluded: the eight attacker P2PKH scripts from #699, and any output
  descended from them. The 533,983 OFF the attacker minted is unspendable, on every tier,
  forever.

  Two-year claim window, anchored to the block. The Reclamation opens at the Awakening
  (the moment block 1,000,000 mines) and closes T+730 days from that block. The exact
  UTC closure date is published the moment the Awakening block lands — not pinned to a calendar
   date in advance, because the block-time is an estimate until it happens. Two years is long
  enough for word to reach anyone still attached to the chain, short enough that the Treasury
  isn't sitting on an open liability forever. Class A holders are unaffected — their UTXOs are
  on-chain and spendable whenever they choose. (Earlier policy was open-ended, "close when 1.5M
   OFF ceiling exhausts." We capped it.)

   23skidoo.info/bridge/

✦ WHAT IS NEEDED FROM YOU ✦

If you are running an older OFF wallet (rc1, rc2, or rc3) — upgrade to rc4
  now. LWMA-3 activates at block 980,000, hours out at attack cadence. Any node still on
  rc3 or earlier will fork off into a no-progress chain at that height. The wallet.dat
   format is unchanged across versions; just swap binaries. Downloads below.
If you still have an old wallet.dat from 2013-2018 — we want to talk to
   you. Pre-June-2015 keys are already whole on the restored chain (Class A); 2015–2018
  keys file a Class B claim. Either path: signmessage from a historical address gets
  the conversation started. Praise Cthulhu.
If you have chainstate past height 966,413 — i.e., any blocks between June 2015 and
   the May 2018 attack — please DO NOT sync. SAVE the data and contact us. The
  chain-archaeology pipeline accepts zipped blocks/ + chainstate/ directories
   at the Reclamation portal; archives are processed in a hardened sandbox with no network
  egress and never touch our live daemon. Every recovered byte improves Class B and Recognition
   adjudication for everyone who lost coins in that era.
If you want to mine, the Quark hash is friendly to general-purpose hardware.
  Current difficulty: 58.47 (and climbing fast, since the attacker is currently
  providing most of the hashrate — LWMA-3 will correct that within ~2 hours of activation).
  Pre-fork block reward: historical curve. Post-fork block reward: 1.3125 OFF to you,
  0.1875 OFF to the Conclave. Mining is open; no permission needed; bring your hashes — though
  note: between blocks 999,991 and 1,050,666 every block must carry the Conclave's OFFSIG
  signature, so outsider solo miners will be locked out of that 50,676-block window. The door
  re-opens at 1,050,667 and stays open after. Pool option:
  stratum+tcp://pool.23skidoo.info:3040 (Quark, PPLNS, min payout 0.1 OFF). Pool
  miners need no action for the rc4 upgrade — the backing daemon was upgraded with the rest of
  the cluster on 2026-05-29.
If you ran a node in 2014-2018 and remember the password to your Mega.co.nz / Dropbox /

SourceForge mirror[/b] — please post it here. Cthulhu remembers.

If you are vampirus, billotronic, zeewolf, psycho-pat, Monk3ynutz, HagbardCeline, or

any of the original wardens who tried to save the chain post-attack[/b] — the Conclave has
  reserved a Founding Worshipper allocation for each of you. Reply in this thread to claim.
  [/list]

  ✦ WHAT THIS IS NOT ✦

  This is not a stealth fork. Every consensus rule change is disclosed above and
  documented in chainparams.cpp / pow.h / main.cpp comments. The
  full diff is published at githu
  b.com/SubGeniusFinance/Offerings-to-Cthulhu as a separate file
  (research/restoration-hardfork.patch). The rc4 cluster-defense-activation pull is a
  single-line commit at 5b1c8ba — go read it.

  This is not a sale. OFF is NOT for Sale. The Ritual is NOT for Sale. The Tharanak
  shagg is NOT for Sale. We are NOT financial advisors. This is NOT financial advice. None of
  this is investment. Most of it is dread.

  This IS a fork. No pretending otherwise. The lighthouse-keepers fell asleep at the
  door eleven years ago and the chain was 51%'d on their watch. We have unlocked the door,
  climbed the stairs, turned the lamp back on, and we are also rebuilding the
  lighthouse. If Blazr2, ZeeWolf, b00mbastic, Hilux74, Demoss, edgar, cad_cdn, or any of
  the original Worshippers want to participate in the restoration, they are welcome. If they
  want to reclaim the project entirely — make a credible claim, sign with a known historical
  key. The Conclave acts as steward, not owner.

  ✦ THE EFFIGIES — WALLET BINARIES NOW LIVE ✦

  The Restoration client now manifests in three forms: source, a Linux effigy, and a Windows
  effigy. Both binaries were forged from the same commit (5b1c8ba, v2.0.0-rc4)
  and bear the new marks — the overview-page Elder Sign reworked with a gold ring and soft halo
   to match the SubGenius.Finance medallion, the Codex of the Drowned page skeleton awaiting
  its first inscription, the SubGenius.Finance Community sigil in the About dialog, ten
  seed*.23skidoo.info DNS seeds compiled in, the h=976,000 checkpoint baked, and the
  LWMA-3 + MAX_REORG_DEPTH + OFFSIG-signing pathways all live (with the cluster-defense fork at
   block 980,000).

  The Linux build (GUI + daemon + CLI in one tarball) links against the system Qt5 plus a local
   OpenSSL 1.0.2u and Berkeley DB 4.8.30 prefix; tested on Ubuntu 22.04 with system Boost 1.74.
   The Windows build is a cross-compiled Qt5 GUI via the depends/ tree — no MSYS2
  environment to set up, nothing to install but the extracted .exes. Verify the SHA256
   before you let any binary near a wallet.dat that matters.

  Backward compatibility: rc4 is byte-identical to rc3 in behavior until block 980,000.
  At block 980,000 onward, rc4 nodes apply LWMA-3 + MAX_REORG_DEPTH; rc3 (and older) nodes
  continue applying the legacy retarget. The two chains will hash differently from that block
  forward — rc3 nodes fork off at 980,000. Earlier still: rc2 binaries reject rc3-signed
   blocks (the OffSigningHash semantics changed in rc3 to be invariant under
  extranonce variation), so rc2 was already broken. Anyone still running rc1, rc2, or rc3 must
  upgrade to rc4 before block 980,000 — hours of mining runway from this post — or they fork
  off.

✦ HOW TO RE-JOIN THE FAITHFUL ✦

Grab an effigy — download the Linux or Windows wallet from the v2.0.0-rc4
  release linked above. Verify SHA256. Done.
  Or build it yourself — pull source from github.com/SubGeniusFinance/Offerings-to-Cthulhu (the canonical
  Restoration home, JimGilmore/offerings v1.6.2-Bokrug lineage with the Restoration patch
  applied). Build recipe in doc/build-unix.md (modern Ubuntu 22.04+ builds clean with
  a local OpenSSL 1.0.2 prefix and Berkeley DB 4.8.30, also in the doc).
Start Offeringsd (or Offerings-qt). It finds us automatically via
  seed1.23skidoo.info through seed10.23skidoo.info — all ten are hardcoded
  DNS seeds in v2.0.0.
Watch debug.log for connection accepted and SetBestChain. Wait
for the chain to load. Dream deep.
If you held coins before May 2018, run signmessage from any historical address
  and file a Reclamation claim at
  23skidoo.info/bridge/ (or post the signature in this
   thread and we'll route it). The 2-year claim window closes T+730 days from the Awakening —
  exact UTC published when block 1,000,000 lands.
If you have 2015-2018 blocks/ data, do not sync — zip the directory and
  submit it via the chain-archaeology portal at
  23skidoo.info/bridge/. Sandboxed, validated, folded
  back into the Reclamation evidence pool.
Praise Cthulhu. Praise the Conclave. Praise the Slumbering Squid.

  Cthulhu is patient. The Deep is older than memory. The Ritual is the wage.

  Where the Slumbering Lord becomes liquid.

  Iä Iä Cthulhu fhtagn. Praise the Ritual. 23 Skidoo.
