What is a Blockchain transmission protocol (BTP)?

Blockchain Transmission Protocol (BTP) is a set of standardized protocols and methods for transmitting information between different blockchain networks. It is designed to allow different blockchain networks to communicate with each other, sharing information and data in a secure and efficient manner. The goal of BTP is to create a common language between different blockchains, enabling the seamless transfer of data and value across different networks. This can help to improve the overall efficiency and scalability of the blockchain ecosystem.

One of the key benefits of BTP is that it enables cross-chain compatibility, allowing different blockchain networks to work together and share information and resources. This can lead to increased interoperability and more efficient use of resources, as different networks can coordinate and collaborate to solve problems and achieve shared goals. BTP can also help to reduce the complexity and fragmentation of the blockchain landscape, making it easier for developers and users to navigate and engage with the technology.

The development and implementation of BTP is still in its early stages, and much work remains to be done to fully realize its potential. However, it is widely recognized as an important step towards creating a more connected and interoperable blockchain ecosystem, and many experts believe that it will play a critical role in the future of blockchain technology and its applications.

Simplified Example

Blockchain transmission protocol can be compared to a set of rules that dictate how information is transmitted from one place to another in a chain-like manner. Just like how a mailman follows specific rules to deliver a letter from one house to another, the blockchain transmission protocol specifies the steps and process for transmitting information on a blockchain network. These rules ensure that the information is transmitted securely, accurately, and efficiently, just like how a well-defined mail delivery process ensures that letters are delivered to the right place and in good condition.

History of the Term Blockchain Transmission Protocol (BTP)

The term "Blockchain Transmission Protocol (BTP)" emerged in 2018, coinciding with the rise of interoperability and cross-chain communication within the blockchain ecosystem. As the limitations of siloed blockchain networks became apparent, the need for a standardized protocol to facilitate seamless data and value exchange across different blockchains arose. Thus, BTP was introduced as a universal protocol designed to bridge the gaps between heterogeneous blockchains.

The development of BTP is primarily attributed to the ICON Foundation, a South Korean blockchain project that recognized the need for interoperability in the burgeoning blockchain landscape. BTP has since gained traction within the industry, with several blockchain projects adopting it as their preferred cross-chain communication protocol.


Bitcoin Transaction Protocol (BTP): BTP is a protocol that is used for communicating between different Bitcoin nodes, such as wallets and mining nodes. It allows for the transfer of transaction information and is designed to be secure and efficient.

Interledger Protocol (ILP): ILP is an open protocol that is designed to enable interoperability between different ledgers, including both blockchain and traditional financial ledgers. It allows for the transfer of assets between ledgers and is designed to be secure and efficient.

Ethereum Whisper Protocol: The Whisper Protocol is a messaging protocol that is used in the Ethereum network. It enables secure, private communication between nodes in the network and is designed to be efficient and resilient to attacks. It is used for a variety of purposes, including sending notifications, broadcasting transactions, and more.

  • Croos-Chain: The meaning of Cross-chain refers to the ability of two or more different blockchain networks to exchange or share data and assets, enabling interoperability between them.

  • Protocol: A protocol in cryptocurrency refers to a set of rules and standards that govern the functioning of a blockchain network.
