Taproot is one of the most important upgrades in Bitcoin’s history. Activated on November 14, 2021, it marked a turning point in how Bitcoin handles privacy, scalability, and complex transactions. Alongside Schnorr signatures, Taproot significantly reshaped Bitcoin’s scripting capabilities—while remaining true to Bitcoin’s conservative, security-first philosophy.
For a protocol that changes slowly by design, Taproot represents a major evolutionary step, not a radical rewrite.
Why Bitcoin Needed Taproot
Since launching in 2009, Bitcoin has proven exceptionally resilient. However, as adoption grew, several structural limitations became more apparent.
1. Scalability and Fees
Bitcoin’s base layer was never designed for high transaction throughput. Block space is limited, and during periods of heavy demand, transaction fees have spiked dramatically—most notably during bull markets in 2017 and 2021.
While the SegWit upgrade improved efficiency and transaction malleability issues, it didn’t fully solve fee pressure or enable more expressive transaction logic.
2. Privacy Limitations
Bitcoin is often described as “pseudonymous,” not private. Every transaction is publicly visible, and advanced transaction types—such as multisignature wallets or smart contracts—were easy to identify on-chain.
This transparency made Bitcoin transactions:
Data-heavy
More expensive
Easier to analyze and track
Taproot was designed to address these challenges without compromising decentralization or security.
What Is the Taproot Upgrade?
Taproot is a soft fork—meaning it is backward-compatible—that improves how Bitcoin handles signatures, scripts, and spending conditions. Its goal is to make complex transactions cheaper, more private, and more efficient, while making them appear identical to simple transactions on-chain.
Taproot consists of three tightly integrated Bitcoin Improvement Proposals (BIPs):
BIP340 – Schnorr Signatures
BIP341 – Taproot
BIP342 – Tapscript
The proposal was introduced by Greg Maxwell in 2018 and implemented into Bitcoin Core primarily by Pieter Wuille. After achieving broad miner consensus, it activated at block height 709,632.
Schnorr Signatures: The Cryptographic Core
At the heart of Taproot are Schnorr signatures, defined in BIP340. They replaced Bitcoin’s original ECDSA signature scheme with a more efficient and mathematically elegant alternative.
Key Advantages of Schnorr Signatures
1. Signature Aggregation
Multiple signatures can be combined into a single signature.
This is especially powerful for:
Multisignature wallets
Lightning Network channel operations
Smart contract execution
On-chain, these transactions look like simple single-signature payments, reducing size and cost.
2. Improved Privacy
Observers can no longer easily distinguish:
Multisig transactions
Lightning channel closes
Smart contract spends
All appear the same on the blockchain—only validity is visible, not structure.
3. Better Security
Schnorr signatures offer stronger mathematical guarantees and simpler proofs, reducing the risk of subtle cryptographic bugs.
Taproot and MAST: Smarter Scripts With Less Data
Taproot itself, defined in BIP341, introduces Merkelized Alternative Script Trees (MAST).
Before Taproot
If a transaction had multiple possible spending conditions, all of them had to be revealed on-chain—even if only one was used.
With MAST
Only the executed spending path is revealed.
All unused conditions remain hidden.
Benefits of MAST
Reduced blockchain data usage
Lower transaction fees
Stronger privacy
More efficient smart contract execution
This makes advanced conditions—such as timelocks, recovery paths, or multisig rules—far more practical.
Tapscript: Expanding Bitcoin’s Script Language
Tapscript, defined in BIP342, upgrades Bitcoin’s scripting environment to support Taproot’s new structure.
What Tapscript Enables
Relaxed script size limits
More efficient validation
Future-proofing for additional upgrades
While Bitcoin is not trying to compete with Ethereum’s general-purpose smart contracts, Tapscript allows safer, cheaper, and more expressive contracts within Bitcoin’s design constraints.
This is especially important for:
Layer-2 systems
Payment channels
Custody and recovery solutions
How Taproot Benefits Bitcoin
Taproot delivers meaningful improvements across multiple dimensions:
🔐 Privacy
Complex transactions are indistinguishable from simple ones.
⚡ Scalability
Less data is stored and transmitted per transaction.
💸 Lower Fees
More efficient block space usage reduces fee pressure over time.
🛡️ Security
Taproot further eliminates transaction malleability and hardens Bitcoin against edge-case attacks.
⚙️ Lightning Network Optimization
Taproot dramatically improves the efficiency and privacy of Lightning channels, strengthening Bitcoin’s second-layer ecosystem.
Why Taproot Matters Long Term
Taproot isn’t about flashy features or short-term hype. It’s about quietly strengthening Bitcoin’s foundation.
By improving privacy without increasing user complexity, Taproot preserves Bitcoin’s core simplicity while enabling more advanced use cases. It also reinforces Bitcoin’s reputation for slow, deliberate, and consensus-driven development—a key reason the network remains the most trusted blockchain in existence.
Closing Thoughts
Taproot is a foundational upgrade, not a cosmetic one. By combining Schnorr signatures, MAST, and Tapscript, it enhances Bitcoin’s privacy, scalability, and security in ways that will compound over time.
Whether you’re:
A long-term holder
A developer
A Lightning Network user
Taproot quietly improves your Bitcoin experience. It doesn’t change what Bitcoin is—but it significantly expands what Bitcoin can do.$BTC

Bitcoin pioneered decentralized digital money and reshaped the global financial conversation. However, its success also exposed inherent trade-offs. As adoption increased, limitations in transaction speed, scalability, fees, and programmability became more apparent.
Rather than altering Bitcoin’s core design—which prioritizes security and decentralization—the ecosystem introduced a powerful innovation: Bitcoin Layer 2 networks. These solutions build on top of Bitcoin, extending its capabilities while preserving the integrity of the base layer.
Understanding Bitcoin Layer 2 Networks
Bitcoin Layer 2 networks are protocols built on top of the Bitcoin blockchain (Layer 1). Instead of processing every transaction directly on the main chain, Layer 2 solutions move most activity off-chain and periodically settle final outcomes back to Bitcoin.
This approach dramatically improves efficiency while still using Bitcoin as the ultimate settlement and security layer.
In practical terms, Layer 2 networks enable:
Faster transaction confirmations
Significantly lower fees
Increased throughput
Greater flexibility and programmability
As a result, Bitcoin becomes more usable for everyday payments and more capable as a foundation for advanced financial applications.
Why Bitcoin Needed Layer 2 Solutions
Bitcoin was intentionally designed to be conservative. Its base layer prioritizes decentralization and censorship resistance above all else.
Key limitations of Bitcoin Layer 1 include:
Block time of ~10 minutes
Limited transactions per second
Rising fees during high network congestion
A restrictive scripting language that limits complex smart contracts
These constraints ensure security but make it difficult for Bitcoin to scale globally or support sophisticated applications. Layer 2 networks emerged as a solution—enhancing Bitcoin’s usability without compromising its foundational principles.
How Bitcoin Layer 2 Networks Work
The core concept behind Layer 2 is off-chain execution with on-chain settlement.
Users interact with Layer 2 systems where transactions, computations, or state changes occur outside the main blockchain. Only essential data—such as final balances or cryptographic proofs—is eventually recorded on Bitcoin.
Different Layer 2 designs achieve this in different ways:
1. State Channels
Participants open a channel on Bitcoin and transact privately and instantly off-chain. The blockchain is only updated when the channel is opened or closed.
2. Sidechains
Independent blockchains connected to Bitcoin via bridges. Assets can move between chains while benefiting from additional features such as smart contracts.
3. Rollups (Emerging for Bitcoin)
Large batches of transactions are bundled together and anchored to Bitcoin, reducing congestion while maintaining security.
Key Bitcoin Layer 2 Networks
Lightning Network
The most widely adopted Bitcoin Layer 2 solution.
Uses payment channels
Enables near-instant, low-cost transactions
Ideal for microtransactions and everyday payments
Makes Bitcoin viable for retail and real-time use
Lightning has transformed Bitcoin from a slow settlement layer into a functional payment network.
Rootstock (RSK)
Rootstock is a Bitcoin sidechain that introduces smart contract functionality.
BTC is locked on Bitcoin and mirrored as RBTC on Rootstock
Supports Ethereum-compatible smart contracts
Enables DeFi, DAOs, and decentralized applications
Anchored to Bitcoin’s security through merge mining
RSK brings programmable finance to the Bitcoin ecosystem.
Stacks
Stacks enables smart contracts and decentralized applications that settle directly on Bitcoin.
Uses a unique Proof-of-Transfer (PoX) mechanism
Smart contracts are written in Clarity
Bitcoin acts as the final settlement layer
Developers can build apps that inherit Bitcoin’s security and finality
Stacks bridges the gap between Bitcoin and Web3 innovation.
Liquid Network
Liquid is a Bitcoin sidechain designed primarily for traders, exchanges, and institutions.
Key features include:
Faster transaction finality
Confidential transactions
Token issuance
One-to-one BTC peg (BTC → L-BTC)
Liquid improves capital efficiency and privacy for professional market participants.
Beyond Scaling: What Bitcoin Layer 2 Unlocks
While scalability is the most obvious benefit, Bitcoin Layer 2 networks unlock far more:
Smart contracts and programmability
Decentralized finance (DeFi)
Token issuance
Atomic swaps
Cross-chain interoperability
Privacy enhancements
Layer 2 solutions help Bitcoin address the blockchain trilemma:
Layer 1: Security and decentralization
Layer 2: Scalability and functionality
Together, they form a balanced and resilient system.
Growing Adoption of Bitcoin Layer 2 Networks
Adoption of Bitcoin Layer 2 solutions has accelerated rapidly.
Developers, infrastructure providers, wallets, and exchanges are increasingly integrating these technologies. A major milestone occurred in 2023, when Binance integrated the Lightning Network, enabling faster and cheaper Bitcoin deposits and withdrawals.
Such integrations signal that Layer 2 networks are no longer experimental. They are becoming core infrastructure within the Bitcoin ecosystem.
Closing Thoughts
Bitcoin Layer 2 networks represent a natural and necessary evolution of the protocol.
Instead of changing Bitcoin’s core rules, they build around them—enhancing scalability, usability, and functionality while preserving the security and decentralization that define Bitcoin’s value.
As adoption continues and tooling matures, Layer 2 solutions will play a central role in Bitcoin’s future. From instant payments to smart contracts and decentralized finance, they are transforming Bitcoin from a simple value transfer network into a versatile global financial platform.

P.S. Сценарии носят плановый (условный) характер и предполагают работу по триггерам, а не “вход вслепую”.🙏

In a groundbreaking move, Apple has given the green light to SaruTobi, the first iOS game to integrate native Bitcoin microtransactions using the Lightning Network. This decision signals a potential shift in Apple’s traditionally restrictive stance on alternative payment systems—a change likely influenced by tightening regulations like the EU’s Digital Markets Act (DMA) and legal battles such as Epic v. Apple.  
Developed by ZBD, SaruTobi—a game originally launched in 2013 but later pulled from the App Store for its Bitcoin integration—has made a triumphant return. This time, it leverages Lightning’s instant, low-cost transactions to enable real-money in-game purchases without the usual App Store restrictions. Players can now spend tiny amounts (as low as a few cents) to retry levels or unlock power-ups, all while maintaining seamless gameplay.  
A New Era for In-Game Payments:
Unlike traditional in-app purchases, which often force developers into rigid pricing tiers and surrender 30% to Apple, Bitcoin microtransactions offer unprecedented flexibility.  
🔹 Frictionless Spending: Payments happen instantly, without interrupting gameplay. 
🔹 Earn as You Play: Players can accumulate sats (tiny Bitcoin units) by completing in-game challenges and later use them for upgrades.  
🔹 Developer Freedom: No middlemen, no arbitrary fee structures—just direct, programmable value flow.  
André Neves, ZBD’s Co-Founder and CTO, calls this a "historic shift," stating: "Bitcoin isn’t just a payment method—it’s a tool to reinvent how games monetize and engage players. The tech was always there; what changed was the regulatory pressure forcing Apple to open up."
What This Means for the Future:
With SaruTobi now live, the door is open for more Bitcoin-powered apps on iOS. Could this lead to a wave of innovation where games reward players in real money? Could we see entirely new business models where in-game economies operate independently of Apple’s fees?  
One thing’s certain: the rules of mobile gaming monetization are changing—and Bitcoin is at the center of it.

Bài viết so sánh Lightning Network với "Con tàu của Theseus", đặt ra câu hỏi liệu bản chất của mạng lưới có thay đổi hay không khi các thành phần của nó được thay thế.

Các thành phần chính của Lightning Network

Về cơ bản, #lightningnetwork là một mạng lưới các kênh thanh toán, nơi người dùng khóa Bitcoin vào các địa chỉ đa chữ ký và cập nhật số dư giao dịch ngoài chuỗi. Đây là một giải pháp quan trọng để mở rộng quy mô của Bitcoin.
Tuy nhiên, các thành phần cụ thể của Lightning Network, như cách thiết lập kênh, định tuyến thanh toán hay quản lý tính thanh khoản, đều có thể thay đổi.
Thiết kế kênh: Hiện tại, Lightning sử dụng kênh Poon-Dryja, nhưng các đề xuất như "cây hết hạn" (timeout trees) hay LN-Symmetry có thể thay thế cơ chế này.
Giao thức chuyển tiếp thanh toán: HTLCs (Hợp đồng Khóa băm-thời gian) là cơ chế hiện tại, nhưng các giải pháp khác như PTLCs (Hợp đồng Khóa điểm-thời gian) hoặc "thanh toán theo gói" (packetized payments) cũng có thể được sử dụng.
Giao thức định tuyến: Giao thức gossip hiện tại có thể bị thay thế hoàn toàn bởi các phương pháp mới như Ant Routing, không cần bản đồ mạng lưới.


Bản chất của Lightning Network

Bài viết kết luận rằng Lightning Network không phải là một tập hợp các thành phần cố định, mà là một ý tưởng cốt lõi: cập nhật các thỏa thuận phân phối quỹ ngoài chuỗi, đồng thời đảm bảo phiên bản mới nhất luôn có thể được thực thi trên chuỗi nếu cần. Các công cụ và phương pháp để đạt được mục tiêu này có thể và sẽ thay đổi theo thời gian. Sự linh hoạt này là cần thiết để mạng lưới có thể tiếp tục mở rộng, giải quyết các vấn đề nội tại và giúp Bitcoin hoạt động như một loại tiền tệ hiệu quả hơn. #anh_ba_cong
