The Protocol Architecture
BigMarkt is five layers stacked. Each layer is independently verifiable, and each is downstream of the one beneath it.
Proof Layer
Server-captured trade history.
The MT4/MT5 Expert Advisor reads every fill from the trader's broker terminal and ships it to the journal in real time. Trades arrive timestamped server-side, with no manual edit path, no screenshot upload, and no after-the-fact rewrite. The journal entry is what the broker confirmed.
Coordination Layer
Public leaderboards and verified rank.
Sanitized aggregate stats (win rate, expectancy, drawdown, R-multiple) are published per profile. Anonymous visitors get a rank-ordered view of who is actually performing, with no email leakage and no self-reported numbers. Rank is downstream of proof.
Signal Layer
Journal-to-journal information flow.
Followers subscribe to verified leaders. When a leader's EA writes a trade to their journal, a sanitized signal record is delivered to each follower's journal as an information event — pair, direction, entry, stop, target, timestamp. The follower's terminal does not auto-execute; the signal is data, not a command.
Settlement Layer
$BMT-routed payment rail (planned).
Planned for a later phase. Subscriptions, leader payouts, copy-vault performance fees, and dispute stakes will settle through $BMT on Solana. Users will top up in USDT, with the protocol routing USDT → $BMT → USDT under the hood so leaders and followers never need to think about token mechanics.
Protocol Layer
On-chain reputation and governance (planned).
Planned for a later phase. A trader's verified history becomes portable and cryptographically attestable. Disputes are resolved by staked arbiters. Protocol parameters — fee splits, slashing thresholds, leader tier gates — are governed by $BMT holders.
Journal-to-journal architecture
A signal does not flow from one broker to another. It flows from one journal to another.
Leader trades
Leader's EA captures the fill and writes it to their journal.
Journal emits signal
The journal publishes a sanitized signal record to each subscribed follower's journal.
Follower receives
The signal appears in the follower's journal as an information event. Execution remains the follower's choice.
This architecture means the protocol never holds broker credentials, never routes orders, and never sits between a trader and their counterparty. Information moves; orders don't.
Broker compatibility
BigMarkt ships an Expert Advisor for MetaTrader 4 and MetaTrader 5. Most regulated retail FX/CFD brokers are supported out of the box. cTrader and broker-API integrations are on the roadmap.

“The journal entry is information, not a command.”
BigMarkt does not advise, manage funds, or place orders. Every signal that flows from a leader's journal to a follower's journal is a record of what happened — a published fact. Whether and how a follower acts on that fact is the follower's decision, executed by the follower, on the follower's own account.
This separation is intentional. It keeps the protocol a transparency tool, not a portfolio manager — which is what regulators distinguish, and what we are building toward as Phase 3 copy execution arrives.
