CPU-friendly blockchain with constitutional gold reserves. Every block mined allocates 25% to purchase tokenized precious metals and 25% to Proof of Personal Custody rewards — hardcoded at genesis, immutable forever.
SOST · Sovereign Stock Token · ConvergenceX PoW · Constitutional Gold Reserves
Four properties hardcoded at genesis, immutable forever, with no governance override. Two enforce credibility (Time, Work). Two enforce value (Scarcity, Store of Value).
Target spacing of 600 seconds between blocks. Difficulty self-corrects every block via the cASERT controller — bidirectional, integer-only, with a 288-block average and equalizer profiles for emergency relief and hardening. Predictable cadence. 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-backed 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.

genesis_block.json50/25/25 split and hard cap live in include/sost/params.h#7,100 carries a Schnorr signature over its PoW commitmentmain and the output hash matches the running binaryTarget block spacing is 600 seconds (10 minutes), maintained by the cASERT unified difficulty adjustment system. The bitsQ primary controller handles hashrate changes; the equalizer prevents short-term emission acceleration.

View all markets →Lines-of-code totals for the SOST stack as of 2026-05-10, side by side with the Bitcoin Core reference implementation. LOC is a rough engineering metric — not a quality, security or decentralisation metric — but it gives a sense of how much surface area the project covers.
| Component | SOST | Bitcoin Core |
|---|---|---|
| Blockchain core (C++ / protocol) | 36,442 | ~280–310k |
| Front-end & explorer (HTML + JS + CSS) | 69,975 | — |
| Materials Engine (Python) | 161,282 | — |
| Geaspirit — geo-mineral ML (Python) | 9,386 | — |
| Auth gateway (Python) | 704 | — |
| Documentation (markdown) | 23,975 | (separate) |
| Total code (excl. docs) | ~278,000 | ~280–310k |

1. The blockchain core alone is 5–7× 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 full SOST stack matches Bitcoin Core in order of magnitude only because SOST is a vertical. The total includes a Materials Discovery Engine (161k LOC) and a geological prospectivity ML stack (Geaspirit) that Bitcoin Core does not contain. Comparing totals across different problem domains is not apples-to-apples.
3. What the numbers do show. SOST is a serious open-source project (~300k LOC total) 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 two external scientific systems.
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 2026-05-10 with find ... | xargs wc -l over each component's own source tree, excluding build artefacts and vendored code. 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.
