CPU-friendly Native Layer 1 Proof-of-Work blockchain. Every block mined allocates 25% to an on-chain Gold Vault (tokenized precious metals) and 25% to Proof of Personal Custody rewards — hardcoded at genesis and enforced by the current consensus rules (any change requires a transparent, network-adopted protocol upgrade).
Important: SOST is a native crypto-asset created solely by Proof-of-Work mining. It does not represent shares, equity, debt, dividends, profit participation, voting rights, ownership of a company, ownership of mining assets, or any redemption or legal claim against the Gold Vault or any reserve. SOST currently has no market price and no associated value. Nothing here is investment advice or an offer of securities.

Four properties hardcoded at genesis and enforced by the current consensus rules — any change requires a transparent, network-adopted protocol upgrade. Two enforce credibility (Time, Work). Two enforce value (Scarcity, Store-of-Value Architecture).
Target spacing of 600 seconds → 144 blocks/day = F₁₂, the 12th Fibonacci
number (12²). Difficulty self-corrects every block via the cASERT controller —
bits_q (Q16.16) as primary regulator plus the ConvergenceX equalizer overlay
(profiles E7–H35), driven by a 288-block average, bidirectional and integer-only.
The schedule is sovereign by design: emission decays by e−1/4 each
131,553-block epoch (≈ Feigenbaum α) toward a hard cap of
≈4,669,201 SOST (≈ Feigenbaum δ). No bulk retargets.
Native ConvergenceX Proof-of-Work — not a fork of Bitcoin SHA-256, Monero RandomX, Ethereum Ethash, Equihash, CryptoNight, Scrypt, X11, or any prior algorithm. Memory-hard by construction: 4 GB dataset + 4 GB scratchpad = 8 GB total per mining thread. Per-block 256-op program changes every block. CPU-friendly by design, ASIC-hostile by construction. Verifier reconstructs sampled rounds in ~0.2 ms with 500 MB of RAM.
Hard cap. The number is the first seven significant digits of Feigenbaum's δ (≈ 4.6692016…), the universal constant that governs the period-doubling route to chaos in dynamical systems — the same kind of system ConvergenceX itself solves. No premine. No ICO. No dev tax. No inflation lever. Forever. Emission decays per epoch with q = e-1/4 ≈ 0.7788.
Each epoch is exactly 2.5029 years — the Feigenbaum α
constant. ~95% of the supply is mined in the first ~12 epochs
(~30 years); the remaining tail decays asymptotically across
deeper epochs:
· ~99% → ~18 epochs (~45 years)
· ~99.9% → ~28 epochs (~70 years)
· ~99.99% → ~36 epochs (~91 years)
· ~99.999% → ~46 epochs (~115 years)
The cap of 4,669,201 SOST is an asymptotic limit by mathematical
construction — it is never strictly hit, only approached forever.
That is the point: scarcity guaranteed by mathematics, not by a
calendar.
Up to half of total supply is gradually converted into gold-funded reserve value, by consensus, every block:
25% — Proof of Personal Custody (PoPC): contracts collateralised
by tokenised gold today, by physically self-custodied gold in the future, with on-chain
cryptographic proof and operator privacy preserved.
25% — Perpetual Gold Vault: protocol-funded, one-way purchases of
tokenised precious metals (XAUT/PAXG today, broader basket later), accumulated forever in a
Heritage Reserve. Observable reserve ratio — not a peg, not a redemption right.
No peg. No redemption right. No price floor. No investment return. No legal claim over the reserve.
Hardcoded at genesis · enforced by the current consensus rules · any change needs a network-adopted upgrade
The original store-of-value plan — converting up to 50% of supply into a gold-funded reserve (Perpetual Gold Vault + PoPC gold custody) — is no longer the active plan. It has been temporarily superseded by the DTD at V15 (block #25,000).
Why: SOST pursues full decentralization — no operator, no treasury. A protocol-funded gold reserve leaned on third-party custodians and tokenized-gold issuers (XAUT/PAXG), adding custody, counterparty and regulatory risk that a sovereign, trustless chain should not carry. Instead of parking 50% of emission in an off-chain reserve, that value is now returned directly, on-chain and supply-neutrally to the participants who secure the network, through the DTD. The gold pages are kept for the historical record; nothing is deleted.
The DTD (Deterministic Token Distribution) is a consensus-run, per-draw distribution of the block’s value to eligible network participants — deterministic (the winner is computed by the rules, not chosen by anyone), keyless at the protocol layer, and supply-neutral (it moves coins, it never mints them). It runs today and intensifies at V15.
The regular DTD distributes the block’s DTD share to an eligible participant, chosen
deterministically by the consensus rules. Historically a draw lands on 1 of every 3 blocks
(it went 2-of-3 at bootstrap #7,100, then 1-of-3 permanently from #12,100).
At V15 (#25,000) it moves to 3-of-3 — a draw on EVERY block, permanently.
Same total value, 3× more & smaller payouts — maximum decentralization. Eligibility is
gated (recent-winner cooldown, anti-dominance) so payouts spread across many participants.
The winner is drawn deterministically and uniformly from the set of addresses that pass every gate (any one excludes an address):
Active signed miner — must be a real SbPoW-signed miner identity (its most recent block at height ≥ #7,100); enforced from #12,100. No signed identity, no eligibility.
Active miner (recency) — from #25,000, must have mined ≥1 block in the last 5,000 blocks; dormant addresses drop out until they mine again.
Recent-winner cooldown — excluded if it produced any of the previous 6 blocks (5 before V13) — stops back-to-back wins.
Anti-dominance cap — excluded if its share of the last 288 blocks is ≥ 10% (from #12,100) — caps concentration.
Uniform & keyless — every eligible address has the same probability; the winner is computed from chain state by the rules — never weighted by balance, stake or any payment.
No purchase, deposit, ticket, KYC or fiat requirement. A block’s own producer is not excluded from that block’s draw.
The DTD Jackpot returns the reserve already accumulated in the Gold Vault + PoPC addresses
(~52,000 SOST at V15) back to DTD winners — instead of leaving it locked in an off-chain-referenced vault.
It fires on a 288-block cadence (~48 h), paying a jackpot of base 100 / cap 500 SOST, first at
height #25,290, draining over ~3 years. It is supply-neutral (it only moves coins that
already exist) and ends when the reserve is empty — after which only the normal per-block DTD remains.
The Jackpot winner is the DTD draw winner of that jackpot block — it reuses the exact same eligibility set as the base draw (signed miner + recent-winner cooldown + anti-dominance + uniform, keyless selection).
No separate entry — there is no ticket, no purchase, no fiat/$-amount rule and no new selection engine.
Broad by design — a jackpot candidate must have mined ≥1 block in the last 20,000 blocks (~19 weeks) — a much wider window than the normal draw’s 5,000. The Historical Jackpot returns the vault to ~the whole network, not a recent few.
Must have an eligible winner — if a jackpot block has no eligible address, nothing is paid: the prize rolls over to the next jackpot and the reserve is left untouched.
The DTD and the Jackpot never mint new SOST. They redistribute value that consensus already assigned. Total supply stays capped at 4,669,201 SOST.
Winners are computed deterministically from chain state by the published rules. No treasury, no admin key, no discretion — height-anchored and enforced at #25,000.
Every draw and jackpot is on-chain and auditable in the explorer. Consensus is open source (MIT). Canonical spec: V15 Historical DTD Jackpot.

| Component | SOST | Bitcoin Core |
|---|---|---|
| SOST — Blockchain core (C++ / protocol) | 45,275 | ~280–310k |
| SOST — C++ consensus & integration tests | 33,216 | — |

1. The blockchain core alone is 6–7× smaller than Bitcoin Core. Bitcoin Core has 15+ years of P2P hardening, scripting (Script + Taproot), thousands of tests, and dozens of network conditions handled in production. SOST does not, and pretending otherwise would be dishonest.
2. The combined total exceeds Bitcoin Core's LOC — but only because the stack is a vertical. It bundles a Materials Discovery Engine (graph neural networks / CGCNN), a hand-rolled front-end and block explorer, plus protocol tooling and extensive test suites — domains Bitcoin Core does not contain. This is not a like-for-like comparison; the comparable blockchain core is the 45k-line figure above.
3. What the numbers do show. SOST is a serious project (~469k LOC total across the stack) with depth beyond a typical altcoin fork — the consensus is custom (ConvergenceX + cASERT), the wallet model is in-house, the front-end is hand-rolled, and the protocol is integrated with a scientific system: the Materials Discovery Engine.
4. What the numbers do NOT show. Network effect, peer count, security audits, deployed value, decentralisation. Those are independent of LOC and Bitcoin leads on every one of them.
Counts measured 2026-06-21 with find ... | cat | wc -l over each component's own source tree, across the SOST stack — the public sost-core (sostcore.com) repository plus the private Materials Discovery Engine R&D repo — excluding build artefacts, vendored code, generated localized pages and bulk data files. The documentation line is a 2026-06-21 cross-repo count and is pending remeasurement. Bitcoin Core figure is the upstream bitcoin/bitcoin master snapshot, code + tests, no docs.
SOST is a Proof-of-Work cryptocurrency where each mined block allocates 25% of issuance to an on-chain Gold Funding Vault by consensus. Conversions to XAUT/PAXG are operational actions executed with public attestations and auditable trails. The reserve is observable on Ethereum mainnet — not a peg, not a guarantee, but a verifiable commitment.
| Consensus | ConvergenceX PoW — memory-hard, CPU-friendly (reference miner CPU-oriented; protocol does not enforce CPU-only at consensus) |
| Monetary Policy | Smooth exponential decay (q=e-¼), Feigenbaum-derived constants, ~30 years to 95% supply |
| Reserve | 25% of every block → tokenized gold (XAUT, PAXG) on Ethereum |
| PoPC | 25% of every block → Proof of Personal Custody rewards (Phase 2+) |
| Governance | None. Consensus rules are immutable at genesis. |
| Unit | 1 SOST = 100,000,000 stocks |
| Address Format | sost1 + 40 hex chars (20-byte pubkey hash) |
| Signature | ECDSA secp256k1 with LOW-S enforcement |
Memory-hard proof-of-work requiring 8GB RAM per mining thread (4GB dataset + 4GB scratchpad). Nodes verify blocks in ~0.2ms with only ~500MB RAM. 100,000 sequential iterations and tight memory coupling raise the cost of a competitive GPU/ASIC port; no claim is made that one is impossible. cASERT unified targeting with bitsQ primary controller and equalizer profiles (E4–H12) for progressive hardening under fast-chain conditions.

Update — no longer active: at V15 (block #25,000) the Gold Funding Vault / PoPC gold-emission plan has been temporarily replaced by the DTD; the description below is kept for the historical record.
25% of every block’s coinbase is allocated to the Gold Funding Vault address by consensus. The Foundation reserves the right to allocate up to 50% of the vault's accumulated SOST exclusively to fund future centralized-exchange (CEX) listings; the remaining SOST funds gold reserves.
Accumulated SOST is converted to XAUT/PAXG via TWAP pipeline and deposited into
a Heritage Reserve on Ethereum mainnet. Observable reserve ratio —
not a peg.
25% of every block’s coinbase is allocated to the PoPC Pool address. Rewards distributed to holders who prove continued custody of their SOST through cryptographic attestation. Model A (self-custody bonds) and Model B (escrow timelock) available.
Explore PoPC →Signed offers, acceptances, cancellations, and settlement notices — off-chain, replay-resistant, cryptographically authenticated. Not chat: private economic coordination with canonical hashes and deterministic serialization.
