Decentralized Mathematical Convergence
Sovereign Stock Token (SOST) is a native Layer 1 proof-of-work (PoW) blockchain that turns computation into order, security and real value. Powered by ConvergenceX, its tested, memory-hard proof-of-work algorithm, SOST enables solo CPU mining and an independently verifiable blockchain.

The network, as the public node sees it
Every value carries where it comes from. These are snapshots written by one server-side collector from the public node (no per-visitor node queries); they are LIVE only while the snapshot is under 45 s old.
Four ways in
What SOST is
A CPU-mined Layer 1 with a fixed, asymptotic supply. Half of every block goes to the miner and half to a deterministic draw among active miners.

Blocks grouped by coinbase (miner) address over the collector's block series. A small, young network with few active miners is expected to show few addresses here. The figures are reported as measured, without a judgement.
Method and limits
Share = blocks of one address ÷ blocks in the window. HHI (Herfindahl–Hirschman index) = Σ share², with shares in %, so 10,000 = one producer. Nakamoto coefficient = the fewest addresses that together produced more than 50 % of the blocks.
Windows. The two boxes use the newest 1,200 and 288 rows. The history splits the same series into consecutive, non-overlapping 288-block windows ending at the newest block; an incomplete oldest window is dropped.
An address is not an entity. One person can mine to many addresses and one address can be shared, so these counts say nothing certain about how many people mine.
Block production is not hashrate. Blocks found in a window depend on luck and timing as well as on work; no hashrate, ownership or intent is inferred from them.

SOST (Sovereign Stock Token) is a native Layer 1 blockchain secured by proof-of-work. It has no ICO, no premine and no venture allocation. The consensus rules changed only through network-adopted upgrades at announced heights (V13, V15, V30000); see governance.
600 s blocks
144 blocks a day. cASERT sets two separate things: bitsQ (Q16.16 numeric target, from the 288-block average, ±15 s dead band) and the Equalizer profile (43 profiles, E7–H35).
cASERT specConvergenceX
Memory-hard CPU proof-of-work: 4 GB dataset + 4 GB scratchpad, 8 GB of RAM in total for mining (threads share one scratchpad). Verification needs about 500 MB, no dataset.
Technology≈ 4,669,201 SOST
Asymptotic cap (Feigenbaum δ × 10⁶). The reward decays by e−1/4 each epoch of 131,553 blocks (~2.5 years); about 95 % is mined in ~12 epochs.

Value returns to the people who run the network
Two deterministic, keyless, supply-neutral draws. Same blocks + same rules + same state = same result: anyone can recompute every winner. Nothing here is random and nothing is a promise of gain.
① Normal DTD · every block
Half of each block's subsidy goes to one eligible miner. Eligibility: an SbPoW-signed block in the last 288 blocks (since #30,000), a 6-block cooldown that yields if it would empty the set, and anti-dominance (≥ 10 % of 288 blocks) armed only with ≥ 11 distinct miners.
Seed: SHA256("SOST_LOTTERY_V11" ‖ hashes h−16…h−1 ‖ h) mod the size of the sorted eligible list. History: 2-of-3 blocks at #7,100, 1-of-3 from #12,100, every block since V15 (#25,000).
② DTD Jackpot V2 · every 288 blocks
Drains the reserve accumulated before #25,000: base 100 SOST, cap 500, at heights #25,290 + 288k. Since #30,000 (first V2 draw #30,186): NODE_BIND + heartbeats in 3 of the last 4 epochs + ≥ 3 SbPoW blocks in the last 2,016, weighted by those blocks; no cooldown or anti-dominance; rollover when nobody is eligible.
Seed: SHA256("SOST_HIST_JACKPOT" ‖ 16 hashes ‖ h) mod total weight. #25,290–#29,898 paid the DTD winner (historical rule).

What you can check today, and what is not claimed
Verifiable
Source code Neob1844/sost-core · genesis_block.json · emission split in include/sost/params.h (50/25/25 for #0–#24,999, 50/50 from #25,000) · SbPoW signatures from #7,100 · anti-dominance in src/lottery.cpp · deterministic builds · every DTD and Jackpot winner recomputable from block hashes.
Not claimed
No post-quantum safety (ECDSA today; PQ is research). No external security audit. No price floor, peg or redemption. No regulatory clearance. No exchange listing. The network is young; few addresses produce most blocks today (measured above). Honest assessment
#40,000 research horizon — not consensus
A study, not an activation commitment (it could move to #50,000). Scenarios: reward evolution (80 % miner / 15 % DTD / 5 % into the Jackpot pool, no new supply), peer persistence and gossip for decentralization, and a developer-gated asset market. Current consensus is unchanged: 50 % miner / 50 % DTD. Read the notice
