Stacks is a Bitcoin Layer 2 network that launched in 2021, designed to expand the functionality of the Bitcoin blockchain. It stands out as one of the first blockchain projects to comply with regulatory standards set by the U.S. Securities and Exchange Commission (SEC). As the broader cryptocurrency market recovers, its native token, STX, has experienced significant price appreciation. Many analysts believe the emergence of Bitcoin NFTs through the Ordinals protocol has further accelerated Stacks' growth. Additionally, the anticipated Bitcoin halving in 2024 is expected to serve as a catalyst for its continued expansion.
This article provides a comprehensive overview of the Stacks network, the STX token, its technological foundations, and future potential.
How Bitcoin NFTs Are Driving Stacks Growth
The introduction of the Ordinals protocol, which enables the creation of NFTs directly on the Bitcoin blockchain, ignited significant interest in Bitcoin-based digital collectibles. While opinions within the Bitcoin community regarding NFTs are mixed, their emergence has undoubtedly become a major narrative within the crypto market, spurring development in related ecosystems.
Stacks has been a direct beneficiary of this trend. The need for a marketplace to trade these Bitcoin NFTs arose, and the Gamma marketplace, built on Stacks, fulfills that role. Consequently, the STX token became a sought-after asset following the explosion of the Bitcoin NFT concept.
Data from market trackers shows STX reaching a high of $0.76 in February, with its price doubling within a single day. This surge highlights the growing interplay between Bitcoin's core layer and its expanding Layer 2 ecosystem.
What Is the Stacks Network?
Stacks is an open-source project initiated by builders dedicated to Bitcoin. Its development team possesses extensive experience in constructing applications and protocols atop the Bitcoin network. Following the block size debates of 2017, it became evident that scaling Bitcoin for more transactions or new use cases required building additional layers on top of it. This realization led to the development of solutions like the Lightning Network and Stacks.
Stacks Network Overview
Stacks is a Bitcoin Layer 2 that enables smart contracts. It maintains a separate ledger for storing data outside of Bitcoin's Layer 1 (L1), allowing developers to build a wide array of applications. Essentially, anything that can be built on Ethereum or Solana can be constructed on Stacks L2.
The platform supports decentralized applications (dApps) and smart contracts that are secured by the Bitcoin blockchain. Stacks addresses Bitcoin's scalability limitations. While Bitcoin is the pioneer blockchain, its functionality is primarily focused on peer-to-peer value transfer. As successors like Ethereum introduced dApps, smart contracts, and NFTs, Bitcoin's design constraints became more apparent. Stacks allows users to interact with dApps and smart contracts, and to create and register NFTs, using its native STX token for fees and network resources.
Originally named "Blockstack," the project rebranded to Stacks in Q4 2020 to distinguish the broader ecosystem and open-source project from its original corporate entity.
Stacks vs. The Lightning Network
Both Stacks and the Lightning Network are Bitcoin Layer 2 solutions, but they serve different purposes. The Lightning Network is primarily a peer-to-peer network for fast, low-cost payments. In contrast, Stacks functions more like a full Layer 2 blockchain designed for expressive smart contracts and complex applications, all while leveraging Bitcoin's security.
The History and Development of Stacks
Stacks has evolved into a key Bitcoin Layer 2 protocol, attracting a growing community of developers building Web3 applications on Bitcoin. Key milestones in its development include:
- 2017: Development of STX began, with a focus on creating a trusted internet and decentralized system.
- 2019: The launch of "Stacks 1.0," the first phase focused on integrating with the Bitcoin blockchain to enhance security.
- 2020: The release of "Stacks 2.0," which introduced its own blockchain and a novel consensus mechanism called Proof of Transfer (PoX).
- January 2021: The Stacks 2.0 mainnet launched, featuring the Clarity smart contract language and providing a platform for decentralized identity management and dApp development.
How Stacks (STX) Works
Stacks employs a suite of protocols and standards to realize a decentralized Web 3.0, emphasizing security and interoperability.
1. The Stacks Blockchain
The Stacks blockchain operates as a secondary chain connected to the Bitcoin blockchain. It creates its own blocks, records transactions, and uses distributed computational resources to support smart contract execution, all while periodically settling its state to Bitcoin for enhanced security.
2. Proof of Transfer (PoX) Consensus
Stacks uses the Proof of Transfer (PoX) consensus algorithm. PoX is a novel mechanism where participants commit Bitcoin (BTC) to the process to earn the right to mine STX blocks and earn rewards. This approach allows the Stacks network to leverage Bitcoin's immense proof-of-work security while maintaining a decentralized and secure economic system.
3. The Clarity Smart Contract Language
The Stacks platform uses Clarity, a programming language designed specifically for smart contracts. Clarity is "decidable," meaning developers can predict exactly what a contract will do before it executes, making smart contracts more secure and auditable. This language is also used by other blockchain projects like Algorand.
4. Decentralized Application (dApp) Development
The Stacks network supports the development and execution of dApps. Developers use the STX token to build, deploy, and interact with applications on the network.

The Stacks Ecosystem
Stacks has broad appeal for developers by supporting the creation of NFTs, DeFi protocols, and other Web3 applications.
NFTs on Stacks
Stacks L2 hosts a vibrant community of artists and creators. Over 650,000 Bitcoin NFTs have been minted on Stacks L2, all automatically hashed to Bitcoin L1 for security. Many NFT builders are also active on Bitcoin L1 using Ordinals, with marketplaces like Gamma.io and Satoshibles facilitating trade.
DeFi on Stacks
The DeFi ecosystem on Stacks is growing rapidly, with over $250 million in value locked in its contracts. Protocols like ALEX and Arkadiko Protocol have distributed significant Bitcoin rewards to users, indicating a thriving early-stage Bitcoin DeFi landscape.
Gaming on Stacks
As with most blockchains, users can enjoy various games on the Stacks network. A key competitive advantage is the ability to play without worrying about personal data breaches, all while having the opportunity to earn STX rewards.
What Is the STX Token?
The STX token is the native cryptocurrency of the Stacks ecosystem. It is used to pay for transaction fees, execute smart contracts, and participate in network governance. Token holders can also stake their STX to participate in the consensus process (through Stacking) and earn BTC rewards.
Key STX Token Information:
- Ticker Symbol: STX
- Primary Platform: Stacks Mainnet
- Launch Date: October 28, 2019
- Max Supply: 1,818,000,000 STX
SEC Qualification of STX
A significant differentiator for Stacks is that its token sale was the first to be qualified by the U.S. Securities and Exchange Commission (SEC). This unprecedented approval for a blockchain project occurred before its mainnet launch. While STX is considered a security and falls under SEC regulation, this regulatory clarity has built expectation that it could play a pivotal role in the expansion of the Bitcoin ecosystem.
STX Tokenomics
The emission schedule for STX is designed to decrease over time. According to the Stacks 2.0 whitepaper, the first four years saw 1,000 STX released per block. This amount halved to 500 STX per block for the next four years, and halved again to 250 for the following four. After that, the emission will settle at a perpetual rate of 120 STX per block.
STX tokens are traded on numerous global exchanges. The initial total supply of 1.32 billion STX was allocated with 6.6% to founders and 7.9% to the Stacks team.
- Mining Rewards: STX is earned by miners who participate in the Proof of Transfer consensus.
- Token Lock-ups: A portion of STX allocated to the project team, advisors, and early investors was subject to lock-up periods to ensure long-term alignment.
- Airdrops: STX has been distributed to the community and users through various airdrop programs to encourage participation and ecosystem growth.
STX Price Analysis
As of recent data, the STX token has shown considerable volatility and growth, reaching new highs not seen since 2022. This price action is largely attributed to the "Ordinals" effect, which has driven renewed interest and value into the Bitcoin ecosystem, directly benefiting Stacks.
Some virtual asset analysts suggest that Stacks' market capitalization has the potential to grow into the tens of billions of dollars due to the influence of Ordinals. Furthermore, Stacks is well-positioned to leverage Bitcoin's blockchain security for building decentralized finance (DeFi), leading to predictions of further price appreciation for the STX token.
Future Outlook for Stacks
The founder of Stacks has outlined a compelling roadmap for the network's future. The next major upgrade aims to introduce a decentralized Bitcoin peg, often referred to as sBTC. This will allow users to easily move BTC in and out of the Stacks L2, significantly enhancing its utility for DeFi.
This upgrade will also include security enhancements, making the chain's finality determined by 100% of Bitcoin's hashing power, and will increase block speeds, freeing the network from being limited by Bitcoin's block time.
The emergence of the Ordinals protocol is seen as complementary to Stacks. While Ordinals brings NFTs to Bitcoin L1, Stacks provides a clear scaling path. Wallets like Xverse and Hiro already support Ordinals, bridging the two ecosystems. The development of sBTC could unlock hundreds of billions of dollars in dormant Bitcoin capital for use in DeFi, mirroring the transformative impact Ordinals has had on Bitcoin NFTs.
