The scalability problem in blockchain technology
Since the birth of Bitcoin, blockchain has proven its potential to become a global decentralized financial and data platform. Bitcoin ushered in the era of digital currency, while Ethereum brought smart contracts and dApps. However, both face limitations regarding:
Transaction throughput (TPS): The number of transactions processed per second is still low. Latency (latency): Slow confirmation times, affecting user experience. Gas fee (gas fee): Transactions often have excessively high fees, especially during periods of network congestion.
To address this, Bitlayer proposes the (Layered Architecture) – a design model that helps separate and optimize each function of the blockchain. This approach allows the network to be fast, secure, and maintain its decentralized nature.
The layered architecture of Bitlayer
Bitlayer divides the system into multiple layers, each layer has its own role and supports each other.
2.1 Layer 0 – Protocol Layer
This is the foundation of the entire network, responsible for:
Explore and synchronize nodes: Help new nodes quickly join the network. Maintain consensus: Ensure all validators comply with network rules. (cross-chain) integration: Allow Bitlayer to connect with other blockchains.
Layer 0 is the reliable framework and communication system for higher layers to operate smoothly.
2.2 Layer 1 – Payment Layer (Settlement Layer)
This is the place to determine the finality (finality) of transactions and protect the integrity of the ledger. Bitlayer uses a hybrid consensus mechanism (hybrid consensus) combining PoS + BFT:
PoS (Proof-of-Stake): Consumes less energy, incentivizes staking.BFT (Byzantine Fault Tolerance): Increases resilience against attacks, enhances reliability.
This mechanism dynamically adapts (adaptive), customizing performance according to the network's needs.
2.3 Layer 2 – Execution Layer (
This is the key to solving the scalability problem. Bitlayer supports multiple solutions:
Rollups: Process transactions off-chain, then write summary data to Layer 1 → significantly increase TPS. State channels: Allow two parties to transact continuously without recording each transaction on-chain. Sidechains: Auxiliary chains serving specific business needs ), for example: gaming, DeFi(, offloading the main chain.
Thanks to this, Layer 2 helps reduce fees, decrease latency while maintaining security.
2.4 Layer 3 – Application Layer )Application Layer(
This is the direct class associated with users and developers:
API and SDK support rapid dApp development. Smart contract testing environment. Compatibility with multi-chain assets and protocols.
The separation of the application layer allows dApps to develop flexibly, without being directly dependent on the consensus mechanism and payment of the network.
Technology supports scalability
3.1 Dynamic Sharding )Dynamic Sharding(
Bitlayer divides the network into multiple shards, processing transactions in parallel. Afterwards, data from the shards is synchronized periodically to Layer 1, ensuring both performance and the integrity of the ledger.
3.2 Modular Smart Contracts )Modular Smart Contracts(
Contracts can be upgraded and modified in parts without the need for a hard fork. This is extremely important for maintaining security and performance in the long run.
3.3 Cross-chain interoperability )Interoperability(
Bitlayer supports the transfer of assets and data between multiple blockchains → opening up a multi-chain ecosystem where dApps operate seamlessly across various platforms.
3.4 Energy-saving consensus mechanism
The combination of PoS + BFT significantly reduces power consumption while still processing transactions quickly and securely.
Practical applications of Bitlayer
4.1 Decentralized Finance )DeFi(
With high throughput and low fees, Bitlayer can:
Operate DEX with instant order matching speed. Build a multi-chain lending/borrowing platform. Deploy stablecoins and a payment system with extremely low costs.
4.2 Game blockchain and NFT
Games require speed and low costs to handle microtransactions and many concurrent players. Bitlayer meets this need thanks to Layer 2:
Fast, continuous trading. Low fees, suitable for micro-payment. Supports tens of thousands of users in the online gaming environment.
4.3 Enterprise System
Businesses can deploy private or hybrid solutions on Bitlayer, while still benefiting from security and connectivity to the public network.
Some applications:
Traceability and verification in the supply chain. Fast and transparent cross-border payments. Decentralized identity and data management.
Challenges and Future Directions
Despite having an impressive architecture, Bitlayer still faces:
Complexity: Maintaining synchronization across multiple layers and shards requires sophisticated protocol design. Implementation difficulties: A sufficiently strong incentive mechanism is needed to attract dApps and businesses to migrate. Legal regulations: Some applications may be restricted by global financial and data laws.
In the future, Bitlayer may expand with:
AI supports smart transaction routing. Layer 2 specialized for each industry ) DeFi, gaming, IoT… (. Integrating new Web3 standards to ensure long-term compatibility.
Conclusion
The layered architecture of Bitlayer is an important step in the journey to solve the scalability problem of blockchain. Separating the protocol – payment – execution – application makes the network fast, secure, and maintains its decentralization.
With the combination of adaptive consensus, dynamic sharding, modular contracts, and cross-chain interoperability, Bitlayer becomes a potential platform for:
Complex DeFi ecosystem. Large-scale game and NFT applications. Enterprise solutions, global commerce.
In the context of blockchain moving closer to mass adoption, Bitlayer can become a model for a high-performance, sustainable, and versatile network of the Web3 era.
