SOST is a CPU-friendly proof-of-work cryptocurrency built on ConvergenceX, a mining algorithm that requires 4 GB RAM and 100,000 sequential rounds per attempt. Every block automatically allocates 25% to a Gold Vault (for purchasing XAUT/PAXG) and 25% to a PoPC Pool (for Proof of Personal Custody rewards). These splits are hardcoded at genesis and immutable.

No. Zero premine, zero ICO, zero VC tokens. The only way to create SOST is to mine a valid block via ConvergenceX proof-of-work. Any block that mints more than the subsidy for its height is invalid by consensus.

~4,669,201 SOST (Feigenbaum δ × 10⁶). This is a hard cap enforced by construction — the emission formula mathematically converges to this upper bound. No tracking of cumulative supply is needed. ~95% will be mined in approximately 30 years (~12 epochs).

No. SOST is not pegged to gold and does not promise price stability. The Metals Reserve is an observable metric (reserve_value / circulating_supply), not a redemption right. SOST holders have no claim on the gold reserve. Markets price this information as they see fit.

March 13, 2026, 00:00:00 UTC. This is mainnet v2 — a clean regenesis following security and custody improvements.

ConvergenceX is designed to be CPU-friendly. Each attempt requires 4 GB RAM and 100,000 strictly sequential rounds — intra-attempt parallelism is eliminated by state dependency. GPUs and ASICs cannot speed up a single attempt. The only parallelism available is running multiple independent attempts, which is what CPU cores already do. Preliminary estimates suggest low ASIC advantage multiples compared to >1000× for SHA-256.

Minimum: 4 GB RAM per mining thread, modern CPU, Linux (Ubuntu 24.04 recommended). Build dependencies: build-essential cmake libssl-dev libsecp256k1-dev. Each thread runs an independent mining attempt, so 4 threads need ~16 GB RAM.

SOST emission follows a smooth epoch-based decay governed by the mathematical constant q = e^-1/4 ≈ 0.7788007830714049:

• Initial reward R₀ = 7.85100863 SOST/block (785,100,863 stocks)
• Each epoch is exactly 131,553 blocks (~2.502907875095892 years — the Feigenbaum alpha constant α)
• Decay: reward(height) = floor(R₀ × q^epoch) where epoch = height ÷ 131,553
• No halvings, no cliffs — continuous ~9.03% annual decay
• Asymptotic maximum supply: ~4,669,201 SOST (Feigenbaum δ × 10⁶, strict limit by mathematical construction)
• ~95% mined in ~30 years (~12 epochs)
• Split: 50% miner · 25% Gold Vault · 25% PoPC Pool
• All arithmetic is deterministic integer-only (Q16.16 fixed-point). No floating-point operations — that would be a consensus failure.

SOST uses two layers of difficulty adjustment:

ASERT (Absolutely Scheduled Exponentially Rising Targets): adjusts the actual difficulty block by block based on chain speed, with a 24-hour half-life. It is the primary long-term calibration mechanism.

cASERT (Constitutional ASERT overlay): acts as a unidirectional emergency brake on emission speed. If the chain is running too fast relative to the ideal schedule (genesis + height × 600s), cASERT tightens ConvergenceX stability requirements across unbounded levels (L1 neutral → L5 → L6+ with no ceiling). It never relaxes when an attacker mines fast — only when the chain is genuinely running slow. If mining stalls for 2+ hours, a decay mechanism gradually reduces the level to prevent chain halt. ASERT corrects speed; cASERT protects emission.

1 stock = 0.00000001 SOST (10^-8), analogous to Bitcoin's satoshi. All internal arithmetic uses stocks (integer-only, zero floating-point).

25% of every block reward flows to the Metals Funding Vault by consensus. The Foundation periodically converts accumulated SOST to XAUT/PAXG via a rule-based TWAP execution policy (rate-limited, anti-momentum, publicly auditable). Purchased tokens are deposited into a Heritage Reserve Vault on Ethereum mainnet — sealed by default, intended to remain perpetual.

Not under normal operation. The Reserve Vault is Heritage sealed. Moving previously purchased reserve assets requires Emergency Catastrophe dual-gate authorization: ≥75% miner signaling (108 out of 144 blocks) AND a Foundation Execution Order. Neither party can act alone. Only two actions are permitted: E1 (rotate to other allowlisted metals) or E2 (liquidate-buy-redistribute).

No earlier than 6 months after genesis (approximately June 2026), and only once market readiness is met — meaning at least one verifiable execution venue with demonstrated liquidity. First purchases target a 50/50 split between XAUt and PAXG.

A rotation proposal between allowlisted metals (E1) can also be submitted following the same dual-gate process: ≥75% miner signaling + Foundation Execution Order.

No. The Metals Reserve does not represent a claim on gold by SOST holders. There are no redemption rights. The reserve is a structural property of the protocol — an observable metric, not a financial product.

Proof of Personal Custody is a voluntary time-bound commitment protocol launched at regenesis (March 13, 2026). Participants prove custody of precious metals (XAUT/PAXG) and are rewarded from the PoPC Pool. It is not tokenization, not staking, and not yield farming. There are two models: Model A (self-custody bonds — you keep gold in your wallet, lock a SOST bond) and Model B (timelocked escrow — deposit gold into immutable escrow, receive SOST immediately).

Any user, including the Foundation, can make direct donations to the Perpetual Vault (Gold Vault: sost1505a886a372a34e0044e3953ea2c8c0f0d7a4724) to support the protocol and endow it with perpetual added value.

Target activation: February 2027 (Epoch 2). By that time, the PoPC Pool will have accumulated approximately 103,160 SOST from coinbase allocations. The escrow contract will be published, verified, and independently audited before activation.

No. Reward rates are operational reference parameters, not guaranteed. They may be adjusted, budgeted per epoch, or paused for security without changing consensus rules. They do not constitute interest, promised yield, or a financial obligation of the protocol.

Model A only: your SOST bond is automatically slashed — 50% goes to the PoPC Pool, 50% to the Gold Vault. Your address is permanently blacklisted. No human can reverse the slash or remove the blacklist once triggered. The protocol has no appeal mechanism.

Model B: immutable escrow deposit — you recover 100% of your metals at maturity, with no slash risk.

No. No entity — including the Foundation — can modify consensus rules after genesis. SOST has no DAO, no voting token, and no multisig with authority over consensus or monetary parameters. The Foundation can only execute a narrow set of operational actions (gold conversion, purchase pauses, PoPC management) under constitutional constraints and public attestation.

If the chain produces zero blocks for 90 consecutive days, the dead-man switch triggers and a 60-day Dissolution notice begins. Critical constraint: if no Emergency Catastrophe was authorized before the chain stopped (no blocks = no miner signaling possible), the reserve remains in Heritage state. Dissolution is a network lifecycle event, not a reserve liquidation mechanism.

No. SOST is a protocol. It is not an investment product, security, or financial instrument. The Foundation makes no representations about future price, utility, or availability. Participants should seek independent legal and financial advice before participating in any cryptocurrency system.

Full validation includes rules R1-R14 (block structure), S1-S12 (script/signature), and CB1-CB10 (coinbase). All consensus arithmetic is 100% integer — zero floating-point in any consensus path. The emission schedule, coinbase split, and difficulty algorithm are immutable at genesis. 15 constitutional rules (C1-C15) define the boundaries.

P2P: port 19333 (default). RPC: port 18232 (default). The node connects to seed.sostcore.com:19333 automatically. RPC requires authentication via --rpc-user and --rpc-pass.

To create your RPC credentials, choose any username and password when starting the node with --rpc-user=<youruser> --rpc-pass=<yourpass>. These are set by you — there is no central registration. The seed node at seed.sostcore.com:19333 connects automatically on first launch.
