Intent is an abstract trend, and few projects pursue it. But this is the type of technology that can "one step change the landscape of the entire Blockchain industry".
CKB and their engineering team have been working on Intent since 2019 and it was not until 2023 that people started to develop Intent. In the CKB world from the early days, they called Intent Open transaction.
Open Transaction (OTX) or Nervos CKB's open transaction format is a groundbreaking and confusing concept. This is considered the dark horse of Nervos in the race between Layer1. Let's explore what open trading (OTX) is and how magical it is through a [Reddit AMA between community member and Jordan Mack](https://www.reddit.com/r/CryptoCurrency/s/ Mf1qYLU3DR) - Co-founder and also software engineer of Nervos in September 2023.

In the previous cycle, the blockchain industry focused on scalability, with Ethereum building Layer 2 solutions and multiple Layer 1 chains raising significant funds. The industry's main goal was to solve the issue of low on-chain performance, which hindered mass user adoption. However, as market volatility persisted, Ethereum’s gas fees dropped to as low as 2 gwei, and on-chain performance was no longer the primary factor limiting blockchain development.As performance issues gradually eased, the industry's focus shifted from scalability to lowering the barriers for users to enter the blockchain space. Chain abstraction and intent abstraction have gained attention, as they enhance blockchain usability and adoption by hiding the underlying complexity and simplifying user interactions. These two abstraction methods not only help users seamlessly operate across different chains but also convert high-level user intents into automated execution, making blockchain technology more accessible to the general public.
Understanding Chain Abstraction and Intent Abstraction
Chain Abstraction and Intent Abstraction are two concepts in the blockchain field, primarily used to discuss technological methods that simplify complexity, enhance interoperability, and improve user experience.
While chain abstraction and intent abstraction share similar goals of simplifying user interactions with blockchain, they differ significantly in terms of the level they address, their scope of application, and their specific implementation.
Chain Abstraction
Chain abstraction refers to hiding the technical details of the underlying blockchain networks during development, so that users or developers don’t need to directly interact with the complex underlying protocols or blockchain infrastructure. For example, through chain abstraction, a user can interact with multiple blockchains within a single application without needing to understand the specific implementations of each chain. The goal is to streamline the user experience and development process, making cross-chain operations more seamless and intuitive.
Intent Abstraction
Intent abstraction involves extracting the user’s intent from specific transaction operations, allowing the blockchain system to automatically handle the underlying transaction logic based on the user's high-level intent. In other words, users only need to express their desired outcome, and the system will automatically determine how to achieve that goal on the blockchain.
The difference between chain abstraction and intent abstraction can be likened to two different experiences when executing transactions on the blockchain. Chain abstraction is similar to Cosmos, where users transfer assets between different blockchains, much like taking public transportation between different cities. Users need to first understand the rules of each chain, find the appropriate cross-chain bridge, manually configure various parameters, such as selecting which blockchain to operate on, and then wait for each chain to process the transaction. This approach offers users more choice and control but requires greater knowledge and effort.
On the other hand, intent abstraction is more like performing a token swap on Uniswap (V3). Users simply express their goal—such as swapping one token for another—and Uniswap automatically finds the optimal liquidity pools and trade routes in the background, handling all necessary operations. Users don’t need to know which specific blockchains or smart contract calls are involved; the system takes care of everything. This method streamlines the entire process, allowing users to simply express their intent, with the system handling the rest.
In summary, chain abstraction addresses the complexity of cross-chain interactions, focusing on interoperability and compatibility in a multi-chain ecosystem, while intent abstraction simplifies user actions by allowing platforms to automatically execute a series of operations based on the user’s expressed intent.
Current Development Status
By comparison, intent abstraction seems to lower the barriers to entry for users more effectively. However, intent abstraction is still in its early stages of development. Although some projects like CoW Protocol, UniswapX, and Zapper have already achieved practical results, many challenges remain, such as addressing privacy concerns, improving efficiency, and preventing centralization.
