Engine Architecture & In-Memory Event Sourcing
The platform is engineered on high-frequency trading (HFT) principles. We eliminated slow SQL databases and garbage collector pauses altogether.
In-Memory Event Sourcing & Shardchains
The state machine lives entirely in server RAM, laid out as flat raw vectors.
Hot State in RAM
Millions of users, orders and transactions sit directly in the CPU L1/L2/L3 caches, delivering access at memory speed.
Append-Only Write-Ahead Log (WAL)
Data is never overwritten on disk. Every change is appended to the tail of an immutable event log.
Masterchain & Shardchains
Every specialised module (WMS, Wallet, Network) is its own state chain (Shardchain), synchronised through the Masterchain.
Data-Oriented Design (DOD)
Heavyweight OOP traded for O(1) direct addressing of memory cells.
A Three-Tier Architecture of Engineered Layers
All business logic is strictly separated into three isolation tiers, following the ATL standard:
platform (Meta Layer)
"Git for business logic". Architects author the schemas and blueprints that encode your rules. No live data lives here — rules only.
instance (Core & Operations)
The high-load engine (Core) that executes those business schemas. Built from 19 specialised microservice blocks.
consumer (BFF Products)
An isolated Backend-For-Frontend facade. End clients work through hardened product APIs and never touch the core directly.
