Bitroot :Opening the Era of Bitcoin Smart Contracts

With Bitcoin's recent halving event and the approval of a Bitcoin exchange-traded fund (ETF), Bitcoin has once again hit a record high of $73,000, once again showing its strong appeal as an investment asset. At the same time, emerging assets in the Bitcoin ecosystem such as Ordinals and Runes have also drawn public attention to the potential applications of Bitcoin. These developments not only open up new possibilities for the future of Bitcoin, but also unprecedented opportunities for investors and market participants, heralding the opening of a trillion-dollar market in the Bitcoin market.

BitrootBRT20 is a root protocol based on the Bitcoin blockchain. It is another innovative Bitcoin blockchain asset issuance protocol after Ordinals and Runes. It mainly uses the transaction and block log of Bitcoin to achieve enhanced blockchain functions, such as asset issuance, decentralized transactions and smart contracts.

This investment research article aims to evaluate Bitroot's technical characteristics, market potential, competitive environment and the main risks it faces, and provide decision support for potential investors.

Technical overview: Bitroot's working principle and function

Bitroot is a Bitcoin-based blockchain meta-protocol BRT20 that utilizes the Bitcoin blockchain to store and transmit additional data, extending the functionality of Bitcoin. By embedding root data in Bitcoin transactions, Bitroot can support complex financial instruments and smart contracts without modifying Bitcoin's core protocol. Here are the technical details and how it works:

1. Transaction Embedding and OP _ RETURN

Bitroot uses Bitcoin's OP _ RETURN operation code to embed data in ordinary Bitcoin transactions. OP _ RETURN is a scripted operation code used to include data in a bitcoin transaction without affecting the validity of the transaction. This approach allows users to insert up to 80 bytes of data into the output of a transaction, which is considered unexpandable (i.e. "burned") by the Bitcoin network, guaranteeing that this data will not affect the money supply of Bitcoin.

Here is an example of using Python and the bitcoinlib library (which is a popular library for handling bitcoin-related operations) to create a bitcoin transaction that contains the output of OP _ RETURN. First, you need to install the bitcoinlib library. If it is not already installed, you can do so with the following command:

You can then use the following code to construct a Bitcoin transaction containing OP _ RETURN data:

2. Asset Issuance and Trading

Users can issue and trade custom digital assets by creating bitcoin transactions in a specific format. For example, to issue a new asset, a user needs to build a bitcoin transaction that contains special metadata that defines the asset's name, total amount, and other attributes. Once such transactions are confirmed by the Bitcoin network and added to the blockchain, the nodes of the Bitroot protocol parse the data and record the corresponding asset creation and distribution in their internal database.

First, let's say you've installed a fictional "Bitroot" Python library. You can install it with the following command:

Next, use the following Python script to simulate issuing a new asset and embed smart contract logic in the transaction:

  1. Smart contract function

Bitroot's smart contract implementation is different from existing EVMs because it is built on top of the Bitcoin blockchain. Bitroot uses a simplified programming language called "Script," which is part of the Bitcoin transaction footbed language, and extends it to support smart contracts. Here are the basic ways Bitroot implements smart contracts

  1. Bitcoin-based scripting language

The execution of Bitroot smart contracts relies on Bitcoin's foot language. The scripting language was originally designed to be non-Turing-complete, meaning that it could not perform all computational tasks and was mainly used for simple conditions such as signature verification. Bitroot extends its capabilities by adding additional operation codes and capabilities to support more complex smart contracts.

2.Embed Data in Transactions

Bitroot's smart contract data is embedded through the OP _ RETURN output in bitcoin transactions. OP _ RETURN allows data to be added to Bitcoin transactions that are not expendable to the Bitcoin network, but can be parsed and executed by Bitroot nodes. The logics and change of state of the smart contract can therefore be encoded and stored in this data.

  1. Analysis and Execution of Smart Contracts

When the Bitcoin network confirms transactions containing OP _ RETURN data, the Bitroot node will parse the data in those transactions and perform the corresponding actions based on the embedded smart contract code. This includes the transfer of assets, enforcement of contractual terms, etc. Each bitroot node verifies and performs these operations independently to maintain network consistency.

  1. Limitations and Functions

While Bitroot enhances the capabilities of smart contracts in this way, its capabilities are limited by the language itself. For example, due to the non-Turing-complete nature of Bitcoin scripts, certain complex computations and conditional logic may be difficult to implement. Bitroot's smart contracts are therefore better suited for applications that do not require complex logic, such as simple financial agreements and asset management.

  1. Future expansion

The Bitroot community is already exploring more ways to extend the capabilities of smart contracts, including possible protocol upgrades and integration with other blockchain technologies to provide broader application support.

4.Bitroot wallets and software tools

To enable users to interact with and take advantage of the functionality of the Bitroot protocol, the developer community has provided a range of tools and wallet applications. These tools include graphical interface applications for asset management, trading, and smart contract interactions, as well as APIs that support automation and integration.

  1. Dual code base and security model

Bitroot runs on two codebases: Bitcoin Core and Bitroot's own software. This means that Bitroot transactions must be confirmed by the Bitcoin network. Because Bitroot operates on the Bitcoin blockchain, it inherits the security and decentralization features of Bitcoin, but also assumes the potential technical limitations and risks of Bitcoin.


In this way, Bitroot extends its functionality with existing Bitcoin infrastructure, allowing users to develop new financial tools and services while keeping Bitcoin core stable and secure. This design fully reflects the adaptability and innovation of blockchain technology, making Bitroot an effective means to achieve high-level functions in the Bitcoin ecosystem.

Competitive Analysis: Bitroot's Place in the Bitcoin Ecosystem

Bitroot, BRT20, a root protocol of the Bitcoin blockchain, while uniquely positioned in its market segment, is also facing competition from multiple fronts, especially from other blockchain platforms and tier 2 solutions. Here's a detailed analysis of the state of the Bitroot competition:

1. Comparison with Ethereum

Ethereum is the most direct competitor, offering comprehensive smart contract capabilities and a large developer community. Ethereum's smart contracts are Turing-complete, meaning they are more complex and powerful than what Bitroot offers. Ethereum also supports a wide range of decentralized applications (DApps), which gives it a distinct advantage in attracting developers and users.

2.Comparison with other side chains and layers

Sidechains and Layer 2 resolution solutions such as Lightning Network, RGB and Merlin provide fast and low-cost transactions. These solutions reduce blockchain congestion by creating off-chain transaction channels, while Bitroot's operations still rely on the main chain processing of the Bitcoin blockchain. This may be at a disadvantage in terms of processing speed and transaction cost, but it is reported that Bitroot is also actively developing Bitcoin Layer 2, which only supports high PTS and low Gas, which may make Bitroot become the second tier of Bitcoin.

2. Competition with its Bitcoin asset issuance protocol

Emerging asset issuance protocols such as ordinals protocol, runes and other non-programmable NFT assets, Bitroot provides a mechanism to extend its functionality on the Bitcoin blockchain, allowing users to create and trade multiple types of custom digital assets and execute complex smart contracts. This allows Bitroot to go beyond simple digital collections to support applications ranging from financial derivatives to in-game assets. And as an extension of the Bitcoin blockchain, Bitroot inherits Bitcoin's high security and decentralized characteristics. This provides a solid foundation of security for transactions and assets on Bitroot, protecting them from centralized risks and cyber attacks.

3. Features and Differentiation

Despite fierce competition, Bitroot is unique in its seamless integration with Bitcoin. By running smart contracts on Bitcoin's existing blockchain, Bitroot benefits from Bitcoin's security and decentralized features, which many other platforms cannot offer. In addition, Bitroot's asset creation and trading capabilities allow the use of Bitcoin's infrastructure without the need to create a new blockchain or token.

4. Legal and regulatory challenges

At present, Bitcoin's anti-censorship has attracted attention, but most of the Bitcoin ecological second layer or sidechains do not have anti-censorship ability. While bitroot assets are stored on the Bitcoin chain, and the Bitcoin layer 2 network will use Bitcoin addresses and synchronize information bilaterally, naturally meeting compliance requirements, Bitroot may be in a strong position to attract large enterprises and financial institutions that are concerned about compliance.
