# Introduction

Many DeFi strategies require low-latency transaction transmission, and transactions that receive broadcasts later or transactions that do not receive attention may lead to missed opportunities. These DeFi strategies include MEV strategies such as arbitrage and liquidation, and market-making strategies such as high-frequency trading (HFT). So we built a fast network on top of the Ethereum p2p network layer. The internal nodes of this network are connected to each other through high-speed links, so that they can quickly send Ethereum messages from one part of the world to another, and at the same time identify and filter spam transactions to improve processing efficiency.

At present, there are many solutions to help developers quickly build DApps, such as alchemy, infura, moralis, quickNode, ankr, etc. The core logic is to provide existing interfaces on the basis of existing basic nodes and at the same time carry out data exchange For additional processing, provide APIs (or SDKs) that are biased towards the application layer, such as NFT API, Game API, Token API, etc. Some solutions also provide methods such as Hybrid Node to improve availability. Developers no longer need to maintain nodes themselves, but quickly build DApps such as NFTs and games by connecting to these APIs. The application layer encapsulation of most basic nodes mainly solves the convenience of the external interface. It does not process and accelerate the processing of transactions, which is not very beneficial to many DeFi strategies. In the field of DeFi (arbitrage, liquidation, market making), low latency has a very important value, often a few milliseconds determine success or failure. Therefore, if an interface with lower latency can be provided, the infrastructure will be more competitive.

We are a web3 Hong Kong start-up company focusing on DeFi infrastructure. Based on long-term DeFi application practice, we have developed a node acceleration service TxBoost. The TxBoost network is composed of many TxBoost Peers distributed around the world. Strategy for collaborative connection and data dissemination, because our Peer nodes have made a lot of transformations for DeFi applications, can be deployed on a large scale, and connected to most nodes on the network, so as to obtain transactions and blocks in the first time, and also send The transaction is sent to the validator node.
