SOST: Proof of Irreversible Convergence. The complete technical specification covering ConvergenceX consensus, monetary policy, Gold Reserve, PoPC, governance model, security analysis, and constitutional rules. Version 4.5.
A mathematically grounded Proof-of-Work based on verifiable dynamical-system certificates. The whitepaper covers the complete protocol specification including consensus algorithm, monetary policy, reserve architecture, custody protocol, and constitutional framework.

The network and mining layers are already partially decentralized: multiple independent nodes, multiple active miners, open-source code, and no admin keys for block production.
However, two economic custody components are still temporarily centralized during Phase I (before V6 activates at block 10,000):
The protocol developer cannot change the constitutional 50/25/25 split, because it is hardcoded at genesis. What remains centralized during Phase I is custody, not the emission rule itself.
Custody transition roadmap:
The custody arrangement during Phase I is at the protocol developer’s operational discretion. The transition to protocol custody at block 10,000 has a hard date encoded in the consensus rules — it is not subject to the developer’s later willingness to step back. The Gold Vault must be able to change form, but not purpose.
