I recently tried the TBaaS Changan chain free public beta experience, and I feel it should be strongly recommended. It makes your development and application assembly mode flexible and efficient, and the whole process of visual operation.
TBaaS is built on the basis of Tencent Cloud, allowing users to quickly build their own IT infrastructure and blockchain services on an elastic and open cloud platform. Using TBaaS can greatly reduce the cost of implementing the underlying technology of the blockchain, and simplify the construction and operation and maintenance of the blockchain.
Features:
- Independent controllable, open source and open blockchain underlying technology platform
- Parallel multi-chain architecture, which can flexibly expand sub-chains according to scenarios
- Support multiple consensus algorithms such as TBFT, HotStuff, Raft
- Support EVM, WASM and other contract engines, Solidity, Go, Rust, C++ and other contract languages
- Support LevelDB, RocksDB, MySQL and other storage engines
- Support ECDSA, RSA, SM and other cryptographic algorithms
- Support consensus nodes, synchronization nodes, SPV nodes and other node types

Documentation Center: TBaaS Changan Chain ChainMaker-Quick Start-Document Center-Tencent Cloud Operation Scenario You can quickly start using TBaaS-Changan Chain Experience Network through this article, Changan Chain Experience Network It is a free and open public test network built and managed by the TBaaS team. Users can experience the related functions of using the TBaaS-Changan Chain Engine here, such as: install contracts, send

The steps for uploading the document are as above, and the official website is still written very clearly. Friends who like it can still follow the document on the official website and still be able to follow it smoothly. Visual fool-like operation throughout the whole process, without any difficulties.
The only small partner who has experienced it for the first time may lie in writing contracts.
- The contract supports four languages: DockerGo, Solidity, Rust, and C++. The types of contract files uploaded by different contracts are different.
- For the contract compilation method, please refer to the development guide Smart Contract Development (DockerGo) or Smart Contract Development (Solidity) or Smart Contract Development (Rust) or Smart Contract Development (C++) .
I have experienced the two methods of DockerGo and Solidity, and the overall experience is still very smooth.
DockerGo: What is needed is that the small partners know Docker first, and Docker is installed on the computer in advance. (Note: When installing the DockerGo contract, the contract name must be consistent with the contract name used when compiling the contract.) I didn’t pay attention to this prompt at the beginning, and I was embarrassed for a long time.
Solidity: Under the recommendation of my friends, there are actually online tools. SmartEditor-the official IDE of Chang'an Chain (friends who have experienced it for the first time [strongly recommended], directly write online, pack it and it's ok)
Others I think there is nothing wrong with it. According to the process, the configuration is OK.
Finally, I attach a screenshot of my success: (Everyone go and experience it)
