⚙️ V15 FULL DECENTRALIZATION FORK — block 20,000 PoW · ConvergenceX PLANNED · pending final implementation & tests · tap to expand
TOTAL DECENTRALIZATION

SOST already has a Proof-of-Work network that works.

Making it more complex than it needs to be only makes the protocol harder for everyone to run and use. That is why we are pursuing the full decentralization of the protocol — native PoW + ConvergenceX, no operator, no treasury.

⚠️ EXPERIMENTAL · NOT FORMALLY AUDITED. This protocol has been hardened empirically — through its live mainnet history and a disciplined trial → error → diagnosis → resolution engineering cycle, with every issue and fix recorded on-chain for full traceability. The result is a system that behaves reliably and securely in practice, but it has not undergone an independent third-party security audit. Run, mine and participate accordingly — at your own risk, with no guarantees.

Gold Vault · PoPC
0%

Future emission that went to Gold Vault / PoPC is redirected to DTD. SOST is not backed by gold — SOST is backed by its own rules.

How DTD works

  • Permanent 1-of-3 cadence: the DTD share accumulates for 2 blocks and pays on the 3rd (lottery block).
  • No valid winner → not lost: it rolls forward and grows.
  • Eligibility: mined ≥1 block in the last 2016 (~2 weeks) — active miners only.
  • Kept: recent-winner cooldown · anti-dominance gate · SbPoW gate · uniform per-address selection.

🏦 What happens to the existing Gold Vault + PoPC SOST

The SOST already accumulated in Gold Vault + PoPC are not kept as a treasury and not sold for listings. They are progressively returned to active miners through a Historical DTD Jackpot: about 100 SOST every ~288 blocks (~48 h) to the DTD winner, using the very same DTD eligibility rules, until the historical balance is exhausted (~3 years). It is a real protocol spend of those coins — no new emission. The reserve returns to the network, not to a founder.

⏳ Upgrade window — after block 19,900, before 20,000

All node operators, miners and explorers must update inside the window. Mandatory mainnet flags:

cd /opt/sost && git pull origin main
cmake -S . -B build -DSOST_ENABLE_PHASE2_SBPOW=ON -DSOST_TESTNET_FORKS=OFF -DCMAKE_BUILD_TYPE=Release
cmake --build build --target sost-node sost-cli sost-miner sost-signtx -j$(nproc)
sudo systemctl restart sost-node

Nodes / miners that do not update may become incompatible with the V15 reward rules after activation.

⚛️ Atomic Swap stays in controlled founder testing (not a public DEX). 🌐 GeaSpirit is an external ecosystem project — not required for SOST consensus. V15 is PLANNED — pending final implementation and consensus tests. Not active. The final build and exact upgrade steps will be published before activation. Details: sostcore.com · t.me/SOSTProtocolOfficial
๐Ÿฆ GOLD VAULT & PoPC POOL โ€” DEACTIVATED, NOT REMOVED
V15 does not delete the Gold Vault or the PoPC Pool โ€” it deactivates them provisionally. Their block emission stops and the balance already accumulated is returned to active miners through the Historical DTD Jackpot, but the modules stay built into the protocol, dormant. They are kept ready to be re-activated in the future, once SOST has the infrastructure to run and operate them properly โ€” exactly as Useful Compute remains in the codebase, dormant, until the network can support its rewarded phase. Nothing is destroyed: capabilities are paused until the protocol can support them.

Developer Note
โ›” FOUNDER TESTING ยท DO NOT USE
โ›” DO NOT USE โ€” FOUNDER TESTING PHASE. The atomic swap is technically built and is being activated at block 15,000 (EVM-only) for the founder's own testing. It has had no external audit and is not validated for public use โ€” using it can cause permanent loss of funds. The figures below describe engineering progress, not readiness. Do not use it until the founder officially announces it is safe. (SOST โ†” BTC is not active โ€” V15.)

SOST OTC / P2P Atomic Swap
A trustless, non-custodial cross-chain swap engine โ€” SOST ↔ BTC ยท ETH ยท BNB ยท USDT ยท USDC ยท PAXG ยท XAUT

Swap SOST for another cryptoasset with a stranger, without trusting them and without SOST ever holding either side's funds. Either both legs settle, or both legs refund โ€” there is no in-between. No intermediary, no escrow operator, no admin key, no upgrade path, no pause switch, no emergency drain. The mechanism is a Hashed Time-Locked Contract (HTLC) on both chains โ€” the same primitive that powers Lightning.

โš™ Decentralised
No custody, no broker, no matching engine. The swap is bilateral & cryptographic.
โœ“ Atomic
Both legs complete or both refund. No partial settlement is reachable.
๐Ÿ”’ Non-custodial
The HTLC is the escrow. No owner can ever move the funds.
๐Ÿ” Verifiable
Every step is a public on-chain tx. Anyone can replay & verify it.

Pairs flagged โš  are issuer tokens โ€” Tether / Circle / Paxos / TG Commodities can freeze any address. Atomic-swap atomicity holds on the SOST side regardless; the issuer-freeze warning is for the counterparty leg only and is fully disclosed pre-swap in the wallet UI. BTC / ETH / BNB carry no issuer-freeze authority.

// HOW IT WORKS โ€” PLAIN LANGUAGE

Alice has SOST, wants BTC. Bob has BTC, wants SOST. They agree price on the OTC/P2P board; everything after is purely cryptographic, with no intermediary touching either coin:

  1. Alice locks her SOST in a SOST-side HTLC, redeemable by Bob with a secret only Alice knows. Refundable to Alice after timeout T1.
  2. Bob locks his BTC in a Bitcoin-side HTLC, redeemable by Alice with the same secret. Refundable to Bob after timeout T2 (T2 < T1 by a wallet-enforced safety margin).
  3. Alice claims the BTC by revealing the secret on the Bitcoin chain.
  4. Bob reads the secret from the Bitcoin chain and uses it to claim the SOST.
  5. Either both legs succeed, or both refund when the timeouts fire. No half-states. No counterparty risk. No third party can move the funds.
// TWO TECHNICAL PATHS
โ‚ฟ BTC path
Native Bitcoin HTLC, BIP-199-style P2WSH redeem script (SegWit v0). Signing delegated to the audited libwally-core (Blockstream โ€” used in Liquid & Green). BIP-143 sighash, BIP-173 Bech32, low-S signatures all from upstream-audited code. No Bitcoin script written from scratch.
โฌจ EVM path (ETH / BNB / ERC-20)
A single 273-line AtomicSwapHTLC.sol. No owner, no upgrade, no pause, no drain. 52 Foundry tests: balance conservation, reentrancy (receiver + token), weird-ERC-20, EIP-6780 forced-ETH, claim/refund ordering, fuzz preimage, fuzz timeout boundary.
// LIVE GATE STATE โ€” verifiable in the repo ยท mainnet UNCHANGED
ATOMIC_SWAP_HTLC_ACTIVATION_HEIGHT = INT64_MAX โ€” SOST consensus gate, sentinel OFF
SOST_BTC_HTLC_SIGNING = OFF โ€” CMake flag, no real BTC signing compiled in
V15_HEIGHT = 20,000 โ€” intended activation height (NOT yet active)
All atomic-swap wallet / RPC / CLI commands refuse --sign --broadcast while the gate stays at INT64_MAX. Activation only after Phase-4/5 sign-off + external audit.

One-line summary. Two people, two chains, one shared secret, two timeouts โ€” or both walk away with their own coins. Full reference at sost-otc.html.

SOST Gold Reference vs. Gold — Monthly, 2019–2026
SOST (1.14 mg gold)   Gold (1 mg)

Gold spot (XAU/USD), month-end close. The SOST line is the gold line × the fixed reference weight (1.14 mg) — it moves only with gold, never by decree. Gold reference, not a market price; once SOST is listed, its price evolves on its own, no longer tied to gold.

// EMISSION CURVE smooth exponential decay ยท q = e-ยผ ยท Feigenbaum ฮฑ epochs ยท ฮด supply cap โ“˜
EMISSION MODEL โ€” Smooth Exponential Decay

SOST uses a smooth exponential decay emission model, not a sharp halving like Bitcoin. Each epoch, the block reward decreases by a factor of q = e-1/4 โ‰ˆ 0.7788, which means a ~22.12% reduction per epoch โ€” a gradual, continuous curve instead of abrupt 50% drops.

The Mathematical Constants
โ€ข Decay factor q = e-1/4 โ€” the natural exponential base raised to -1/4. This produces the smoothest possible decay curve: R(e) = Rโ‚€ ร— qe
โ€ข Feigenbaum ฮด โ‰ˆ 4.6692 โ€” determines the hard supply cap: ฮด ร— 10โถ = 4,669,201 SOST. This is the mathematical limit of the geometric series โ€” no counter, no tracking, just convergence.
โ€ข Feigenbaum ฮฑ โ‰ˆ 2.5029 โ€” determines the epoch length: ฮฑ ร— 10โต = 131,553 blocks per epoch โ‰ˆ 2.503 years.

Epoch Structure
โ€ข Epoch 0: 7.85100863 SOST/block (genesis reward)
โ€ข Epoch 1: 6.11448985 SOST/block (โˆ’22.1%)
โ€ข Epoch 2: 4.76155747 SOST/block (โˆ’22.1%)
โ€ข ...each epoch decays by the same smooth factor...
โ€ข Epoch 11: 0.60574158 SOST/block
โ€ข ~95% of total supply emitted by epoch ~12 (~30 years)
โ€ข Emission continues through ~82 epochs (~205 years) until rewards become negligible
โ€ข 100% emission is asymptotic โ€” mathematically approaches but never reaches the cap

Why Feigenbaum?
The Feigenbaum constants (ฮด = 4.6692..., ฮฑ = 2.5029...) are universal mathematical constants from chaos theory that describe the rate at which period-doubling bifurcations occur in dynamical systems. In SOST, they are used purely as irrational constants to set the supply cap and epoch length โ€” values that cannot be derived from simple fractions, making them resistant to arbitrary parameter choices. The emission curve is deterministic, immutable, and verifiable by anyone from the genesis block.
