Bitcoin is no longer limited to simple transactions. Emerging platforms like Stacks, Core, Merlin Chain, and Elastos are unlocking smart contracts and DeFi on Bitcoin’s secure foundation. These technologies bring advanced features such as zero-knowledge proofs, merged mining, and Ethereum compatibility—transforming Bitcoin into a hub for decentralized applications without changing its core protocol.
Stacks(STX): Enables Direct Smart Contract Use on Bitcoin

Stacks (STX) introduces smart contract functionality to the Bitcoin network through its Proof of Transfer (PoX) consensus mechanism. This system allows decentralized applications (DApps) to utilize Bitcoin’s existing security and liquidity while operating independently of the core Bitcoin protocol. Stacks tracks the Bitcoin blockchain’s state and uses it to settle its transactions directly on Bitcoin’s Layer 1.
This approach provides smart contracts with a secure environment by anchoring them to Bitcoin’s hashpower. The Stacks ecosystem allows developers to build decentralized finance (DeFi) tools that leverage Bitcoin’s native properties. By functioning in parallel with the Bitcoin network, Stacks extends Bitcoin’s capabilities without compromising its foundational structure.
Core(CORE): Blockchain Blends PoW and DPoS for Scalability

Core blockchain integrates the Satoshi Plus consensus model, which combines proof-of-work (PoW) and delegated proof-of-stake (DPoS). This hybrid mechanism seeks to balance decentralization with scalability by utilizing Bitcoin’s security features along with delegated staking. As a result, Core can support higher throughput and improved consensus efficiency.
The platform also supports Ethereum Virtual Machine (EVM) compatibility, making it possible for Ethereum-based decentralized applications and smart contracts to operate on the Core network. Governance is managed through a decentralized autonomous organization (DAO), which oversees development decisions and transaction policies. Developers contributing to the ecosystem receive S-Prize tokens as incentives, encouraging active participation and growth.
Merlin Chain(MERL) Builds Layer 2 Infrastructure for Bitcoin

Merlin Chain developed by Bitmap Tech, introduces a Layer 2 solution aimed at expanding Bitcoin’s scalability and smart contract capabilities. It integrates technologies such as zero-knowledge (ZK) rollups, fraud proofs, and decentralized oracles to ensure security and performance. These features help manage data validation and transaction integrity while optimizing throughput.
MERL, the network’s native token, is utilized for staking, transaction fees, and liquidity provision. The project emphasizes support for Bitcoin-native assets and protocols, offering infrastructure for both developers and users within the Layer 2 space. With a total supply of 2.1 billion tokens, MERL is distributed across the public, development initiatives, and core contributors. The token is listed on several major exchanges, including OKX, KuCoin, and Bybit.
Elastos(ELA) Introduces BeL2 to Scale Bitcoin Smart Contracts

Elastos (ELA), launched in 2017, now offers the BeL2 solution to enhance Bitcoin’s scalability and smart contract integration. BeL2 applies SmartWeb architecture and supports merged mining, allowing Bitcoin’s hashpower to secure the Elastos network. This connection ensures network security while enabling faster and more efficient transactions.
The infrastructure is structured across multiple layers, including a blockchain core, runtime, carrier network, and software development kits (SDKs). These components work together to isolate applications while maintaining consistent functionality. BeL2 also uses Zero-Knowledge Proofs to address privacy issues and speed limitations, supporting secure and scalable smart contract deployment. Elastos has gained recognition in the community for its security approach and consistent development in Bitcoin-related applications.
These platforms contribute to expanding Bitcoin’s capabilities by providing frameworks for smart contracts and decentralized finance without altering the original Bitcoin protocol. Through Layer 1 and Layer 2 innovations, the ecosystem supports a growing number of use cases, including asset tokenization, decentralized governance, and automated financial applications.
