Introduction to BTTC: A TRON-Based Layer 2 Solution

Suggest Edits

What is Layer 2?

Layer 2 networks are scaling solutions built on top of existing blockchains (Layer 1 blockchains such as Ethereum and Bitcoin). They improve transaction speed and lower fees while retaining the security of the underlying blockchain to the greatest extent possible. By processing most computing and transactions off-chain and submitting only essential data to the main chain, they enhance blockchain scalability.

Why Layer 2 Solutions Are Needed?

The blockchain trilemma—balancing security, scalability, and decentralization—restricts L1 blockchains' performance:
Extremely low transactions per second (TPS) and high gas fees during congestion make frequent transactions impractical.
L2 networks resolve these issues by combining off-chain computation with on-chain settlement without compromising security.

Overview of BTTC: A TRON-based L2 Solution

As an L2 scaling solution, BitTorrent Chain (referred to as “BTTC” below) strives to tackle scalability and availability challenges without undermining blockchain decentralization. Leveraging the TRON ecosystem and developer community, it uses the TRON-based token, BTT, as its native token for gas fees and staking and decentralized governance. BTTC delivers ultra-high throughput and excitingly low transaction fees.

BitTorrent Chain is the first scalable heterogeneous cross-chain interoperability protocol on TRON, featuring PoS (Proof of Stake) consensus mechanism and multi-node validation. It supports smart contract extension through side-chains and is compatible with Ethereum-based smart contracts. Together with many other functions it boasts, it enables developers to migrate and develop DApps on the chain without a hitch.

BTTC now supports the cross-chain transfers of assets from Ethereum, TRON, and BSC (Binance Smart Chain) to BTTC. Moving forward, BTTC will support more public chains.

Core Advantages:

Low Costs: With L2 technology, transaction costs are significantly lower than those on Layer 1 blockchains.
Fast Confirmation: Transactions are confirmed at lightning speed to provide users with a near-instant on-chain experience.
Robust Cross-chain Connectivity: BTTC supports asset transfers across multiple chains to expand TRON's reach.

How does BTTC work?

BTTC adopts an innovative three-layer architecture for high performance and cross-chain interoperability while maintaining decentralization:

1. BTTC Layer (Execution layer)

  • Consensus mechanism: Proof of Stake (PoS)
  • Core Features:
    • Fully compatible with the Ethereum Virtual Machine (EVM)
    • Managed by decentralized validators
  • Key Functions:
    • Process all transactions
    • Execute smart contracts
    • Produce transaction blocks

2. Delivery Layer (Relay layer)

  • Technology: Based on Tendermint
  • Management structure: Jointly managed by a group of trusted validators
  • Core Functions:
    • Synchronize the state of the BTTC Layer (including transactions, blocks, and validator information)
    • Facilitate communication between the BTTC Layer and the Contract Layer
    • Ensure data consistency across chains

3. Contract Layer (Settlement layer)

  • Core Functions:
    • Receive and store state data from the Delivery Layer
    • Provide ultimate security guarantee

Cross-Chain Connectivity

Leveraging its unique cross-chain capabilities, BTTC bridges diverse blockchain networks and enables seamless asset transfers, along with value exchange, across the multi-chain ecosystem.

Standout Features

Chain-Agnostic: BTTC boasts exceptional compatibility, supporting cross-chain interactions between leading public chains including Ethereum, TRON, and Binance Smart Chain (BSC). For example, it enables hassle-free asset transfers between Ethereum's DeFi ecosystem and TRON's network of diverse applications. Its extensive compatibility grants users higher flexibility and allows resources from different blockchain ecosystems to be shared and integrated.

Decentralized Design: BTTC adopts a decentralized network of validator nodes for cross-chain verification. Distributed globally, these nodes work together to validate and confirm cross-chain transactions. By decentralizing the verification flow, this design boosts the stability and reliability of cross-chain processes by removing centralized control and preventing system failure caused by single points of failure or malicious attacks.

Core Competencies

1. High Throughput

  • Advanced Architecture: BTTC's innovative cross-chain structure was created explicitly to deliver high TPS (transactions per second). By optimizing transaction processing and resource allocation, it efficiently handles massive volumes of transactions. In real-world scenarios, BTTC swiftly processes cross-chain transaction spikes without congestion or delays.
  • Ready for High Demand: From financial institutions handling ongoing cross-border payments to DApps managing a massive volume of user transactions, BTTC readily supports large-scale workloads.

2. Low Transaction Costs

  • Significantly Reduced Gas Fees: Gas fees are often a major concern for users in cross-chain transactions. Compared to other solutions, BTTC stands out in this regard: By fine-tuning its underlying technology and employing a carefully engineered economic model, BTTC substantially reduces the gas costs involved. Users can transfer assets across chains at a remarkably lower fee, making the process far more cost-effective.

3. Fast Transaction Confirmation

  • Rapid Confirmation: While traditional cross-chain bridges can leave users waiting hours for transaction confirmations, BTTC delivers near-instant transaction confirmation through optimized consensus algorithms and validation flows.

4. Exceptional Security

  • Multi-Signature & Distributed Verification: BTTC leverages both multi-signature and distributed verification mechanisms to safeguard cross-chain transactions. Each transaction needs to be confirmed by multiple validators through signatures, and only transactions meeting the predefined rules are approved. This approach prevents tampering and malicious attacks since an attacker would need simultaneous control over multiple nodes—an almost impossible feat in a distributed network.
  • Automated Asset Management: BTTC uses smart contracts to precisely control the locking and unlocking of assets. Cross-chain transfers begin by locking the original assets on the source chain and creating an ownership credential on the destination chain for the recipient. Once all verification steps are complete, the original assets on the source chain are unlocked, and users receive their assets on the destination chain. This process is automated by smart contracts, minimizing human intervention and ensuring secure, accurate asset transfers.

5. User-Friendly Design

  • Intuitive Interface: BTTC's interface is designed for ease of use, catering to both beginners and experienced users. It simplifies cross-chain transactions into a few straightforward steps.
  • Straightforward Usage: From selecting source and destination chains to entering the amount of assets and receiving address, users can complete transactions easily without needing in-depth knowledge of blockchain technology.

BTTC's cross-chain technology stands out with its unique architecture and powerful advantages, offering a fast, low-cost, and highly secure solution for asset transfers in an increasingly multi-chain world. Whether you're a user who frequently moves assets across chains or a DApp developer building cross-chain applications, BTTC is undoubtedly a top choice. As the multi-chain ecosystem expands, BTTC is poised to expand its technological impact and evolve into a vital piece of infrastructure connecting diverse blockchain networks, driving the blockchain industry into its next phase.
