What is web3 middleware?

Middleware is a system that facilitates communication between various applications on top of different architectures. Applications can share information and resources between different technical architectures with the help of middleware.

Middleware is a word often talked about in the blockchain field nowadays, but it is not just now. HTTP protocol in the Web 2 era is actually a kind of middleware, with HTTP protocol, application developers can develop products more easily and try and validate ideas quickly, which eventually formed the prosperous development of the Internet.

The HTTP protocol has played a huge role in the popularisation of the Internet, and many giant companies have grown up based on the HTTP protocol, such as google, amazon, facebook in foreign countries, and Tencent and Alibaba in China, and the HTTP protocol can be seen as the middleware of the Web 2.0 era.

In the Web 3 era, blockchain middleware can be understood as a class of services that provide communication between blockchain and application software, helping developers to make better use of the underlying protocols and develop applications better and faster.

MEMO decentralized storage protocol serves as the infrastructure of Web3, and middleware is part of the infrastructure. MEMO has also implemented a series of innovative features in middleware services, such as cross-chain interaction and node services, in order to achieve better services and build a solid foundation.

Cross-chain Interaction

Cross-chain interaction is one of the most basic functions of middleware, its role is to connect applications on two or even more public chains to achieve data transfer, transaction settlement and other application services between multiple parties, no longer limited to the situation where one public chain sets one rule, so that the chain and chain form a close connection, and ultimately achieve ecological interoperability between the chains.

Thanks to the single-chain structure of MEMO decentralized storage protocol, it is compatible with most of the Turing-complete mainstream public chains in the market, bridging the technical gap between the major public chains and connecting them to each other, making both cross-chain settlement and application development more convenient, and helping all blockchain projects achieve cross-chain interoperability.

In addition to cross-chain interaction, the most unique feature of MEMO decentralized storage protocol is to achieve cross-ecological interaction, that is, the interaction between the Internet and blockchain. With strong ecological compatibility and a large number of node networks, the original data of Internet enterprises is firstly encapsulated and stored, and then through slicing processing and unique transmission protocols, with the help of smart contracts, identifiable on-chain data is generated for on-chain processing, which is then controlled by temporary framework services built on MEMO’s decentralized storage protocols, allowing effective The data is then controlled by a temporary framework service built on the MEMO decentralized storage protocol, allowing effective data interaction between the Internet and the blockchain.

Node services

Another function of the MEMO decentralized storage protocol middleware service is to provide node services such as complete data storage and privacy computing on top of data interoperability between the Internet and the blockchain.

MEMO ensures the complete decentralization of storage nodes with a new design concept and a model that does not rely on the arithmetic competition. In terms of architectural design, MEMO optimizes and innovates the traditional blockchain storage architecture by only recording role and transaction information on the blockchain, while storing a huge amount of data in a shared mode on edge storage devices. This model of using common edge devices not only ensures complete decentralization and absolute privacy and security, but also makes the node service threshold significantly lower.

Edge devices take up most of the storage capacity of fixed and cold data, on the one hand relieving the pressure of data storage on the chain, a large amount of data is stored under the chain, ensuring that the cache space for data on the chain is large enough and the computational efficiency is high enough, on the other hand reducing unnecessary data transmission, extracting specified data only when needed, classifying and optimizing data, reducing space costs and network expenses.

The middleware is one part of MEMO’s Web infrastructure, and the ultimate goal of MEMO is to open up the infrastructure services so that the MEMO ecosystem covers the entire Web3 bottom layer and forms a unified Web3 rule.
