Stacks (Stx)-L2 Blockchain That Enhances Bitcoin'S Functionality

Under the pseudonym of Satoshi Nakamoto, Bitcoin was developed in 2009 as a blockchain platform that allows users to store and transact values in a decentralized manner. 

With the evolution of the crypto industry, there are growing needs for smart contracts functionalities, non-fungible token (NFT) creation, decentralized applications’ development and more. However, Bitcoin was not designed to deal with these complex programs. 

To address these challenges, Stacks Layer-2 (L2) network was introduced that will enable smart contracts and dApps to use Bitcoin as a secure base layer, without changing its core essence.

In this article, we will look into the basics of Stacks blockchain, its features, how it makes Bitcoin useful, and functionality comparison between Stacks and Bitcoin.

What is Stacks Blockchain? 

Stacks is an open-source Layer 2 blockchain ecosystem that extends Bitcoin’s core functionalities by enabling dApps and smart contracts within its ecosystem. It allows developers to leverage the security, capital, and network effects of Bitcoin, without modifying its fundamental design. 

Stacks uses Proof of Transfer (PoX) consensus that connects Bitcoin, the king of cryptocurrencies, and Stacks. PoX reuses Bitcoin’s energy and security to validate transactions on Stacks, which creates a secure connection between both blockchain networks. Stacks layer can be used by developers to build any application they can be constructed on other smart contract platforms like Ethereum, Solana, Avalanche and others.

According to Stacks’ whitepaper, the goal of the Stacks L2 is to grow the Bitcoin economy by turning BTC into a productive asset by enabling various decentralized applications to run efficiently on top of Bitcoin. 

Features of Stacks Blockchain

There are multiple features that make Stacks a reliable blockchain network for users. They are as under:

Smart Contracts with Clarity Language

Stacks uses Clarity, a smart contract programming language that provides security and predictability. The design of Clarity makes it possible for developers to execute the contracts in a clear and simple manner. This minimizes the potential weak points of the software and risk of runtime errors, boosting the confidence of users. 

Bitcoin-Secured Consensus

Stacks uses a unique consensus mechanism called Proof-of-Transfer, that anchors Stacks’ blocks to Bitcoin. This means that all Stacks’ transactions use Bitcoin’s security, with block data hashed and stored on the Bitcoin blockchain.

Knowledge of Bitcoin State

The smart contracts on Stacks has the ability to read Bitcoin transactions and state changes and execute smart contracts triggered by Bitcoin network activities. This ability helps to keep decentralized peg consistent with BTC locked on Bitcoin L1.

Scalable and Fast Transactions

Stacks offers scalability and high performance and scalability through faster Stacks layer blocks. The block time on Bitcoin is approximately 10 minutes while for Stacks, it is just 5 seconds. 

Modular and Open dApp Development

Stacks supports modular and open decentralized applications, which allows developers to build upon existing applications. This feature enables complex functionalities that use Bitcoin’s security.

sBTC – Programmable Bitcoin

Stacks introduces sBTC, a 1:1 Bitcoin-backed asset assisting trustless movement of BTC into the Stacks layer. By this, developers can implement smart contracts and decentralized applications without modifying the core protocol of Bitcoin. 

Support for Bitcoin Ordinals and NFTs

The Stacks blockchain helps in the creation and management of non-fungible tokens on the Bitcoin network that provides artists and creators with an opportunity to use the secure network for their collectibles. 

How does Stacks make Bitcoin useful?

Stacks blockchain was developed to enhance the functionality and usefulness of the Bitcoin network. Here’s how: 

  • The Stacks L2 network has introduced smart contract functionality on the Bitcoin network by using its Clarity programming language. This increased functionality makes Bitcoin useful for developers to build decentralized finance (DeFi) protocols and other dApps.
  • Stacks uses Bitcoin as a security provider to its ecosystem, which means that every application on Stacks uses Bitcoin’s security system. 
  • Stacks makes Bitcoin useful for DeFi platforms as they are now able to function with the network. 
  • Stacks has also helped the Bitcoin holders to earn yields on their holdings without leaving the Bitcoin ecosystem. 
  • Stacks has made Bitcoin’s durability useful for artists and creators to develop and manage their NFTs. For example, Projects like Gamma and Byzantion are allowing the creation of NTFs by using Bitcoin’s security. 

Functionality Comparison: Bitcoin vs Stacks Blockchain

FeaturesBitcoinStacks
Main PurposeDigital currency and store of value.Smart contracts and dApps anchored to Bitcoin.
Consensus MechanismProof of Work (PoW) consensus.Proof of Transfer (PoX) linked to Bitcoin mining.
Smart Contract SupportNo native smart contract support.Yes, by using the Clarity programming language.
Token StandardOnly BTC (no native token standard).Supports SIP-010 (similar to ERC-20).
SecuritySecured by Bitcoin’s hash power.Uses Bitcoin’s Security via PoX consensus. 
ScalabilityLimited, slow transaction speed and high fees.More scalable due to a separate layer and micro blocks.
InteroperabilityVery limited and not designed for programmability.Designed to extend Bitcoin without changing it.

Conclusion

Stacks blockchain is playing a crucial role in crypto world by making Bitcoin prepared for real-world use cases. With smart contracts, decentralized applications, and NFTs on the Bitcoin network- it has unlocked the advantages for Bitcoin over other blockchains like Ethereum and Solana. 

Stacks bridges Web3 innovations with Bitcoin’s strong security and opens the door to a more advanced decentralized ecosystem. It makes Bitcoin future-ready, which will enhance its usability from just being a store-of-value asset to a foundation stone for a full-fledged programmable economy.
