L2 Modular Framework

Basic module layer (transaction execution engine, state manager, data availability layer).

💥 EBN L2 Modular Framework: Foundation Module Layer – The “Core Engine” of the Bitcoin Ecosystem

EBN's L2 modular framework forms the underlying foundation of its "blockchain operating system," while the basic module layer is the core of the entire system's performance and security. It handles efficient L2 transaction processing, precise state maintenance, and the commitment to data integrity on Layer 1 (the Bitcoin mainnet).

The following is a professional summary of the basic module layer, dedicated to showcasing the powerful impact of its core functions:

---

1. Transaction Execution Engine

Positioning: High-speed transaction processing unit of the EBN Layer 2 network.

Core Function	Professional Explanation
Transaction Receipt and Verification	Receive L2 transaction requests from users, perform fast validation related to the UTXO model, and ensure the validity of inputs and outputs.
Transaction sorting and packaging	It is responsible for efficiently sorting massive L2 transactions (to prevent preemptive attacks/MEV) and aggregating them into lightweight L2 transaction batches.
High throughput achievement	As the core of the L2 Sequencer function, it enables the Bitcoin network to achieve unprecedented high concurrency and low latency transaction execution capabilities, and is the direct source of L2's high performance.

2. State Manager

Positioning: To maintain the consistency and immutability of Layer 2 network data as a "digital ledger".

Core Function	Professional Description
Global state maintenance	The global state tree of the off-chain L2 network (usually based on a Merkle Tree/Patricia Tree) is maintained and updated in real time, which is the sole source of truth for all smart contracts and account balances.
Atomicity and Immutability	Ensure that every state update is atomic, meaning that a transaction either succeeds completely or fails completely, eliminating intermediate states. Simultaneously, maintain a local snapshot to ensure the final determinism of state updates.
Bearing complex logic	Providing a stable and reliable execution environment for functional extension layers (such as DeFi lending and GameFi states) is the foundation for EBN's ability to run complex Turing-complete logic.

3. Data Availability Layer (DA)

Positioning: The ultimate line of defense to ensure the transparency, verifiability, and censorship resistance of L2 transaction data.

Core Function	Professional Description
Transaction data sharding storage	L2 transaction batch data is sharded and distributed across a multi-node network to ensure that data is not lost even if some nodes go offline.
Merkle proof provided	A precise Merkle Proof is generated for each transaction batch. External Watcher nodes and users can use this proof to efficiently verify the authenticity and validity of transactions simply by reading the anchored state root on L1.
Anti-censorship guarantee	Even if the Sequencer maliciously blocks withdrawals or submits an incorrect state, the validator can still rebuild the state and enforce withdrawals on L1, ensuring fund security and user sovereignty, since all transaction data is publicly available at the DA layer.

🚀 The profound value brought by the basic module layer

The three-in-one design of the foundational module layer forms the high-performance, highly secure, and scalable Layer 2 core framework of the EBN platform:

High-performance flywheel: The transaction execution engine achieves high throughput, completely breaking through historical bottlenecks such as transaction congestion and high gas fees.

Absolute state security: The state manager provides guarantees for the trustless nature of L2 financial applications through atomic and tamper-proof mechanisms.

Bitcoin-level trust: The data availability layer elevates the transparency and verifiability of L2 to a security level approaching that of the Bitcoin mainnet through cryptographic proofs and distributed storage.

This foundational module layer acts like a pluggable L2 kernel, providing an unbreakable infrastructure for upper-layer functional extension modules and applications.
