Introduction
XuperUnion is the first open-source project in the XuperChain ecosystem and the underlying solution for building super alliance networks.
-
Key features
-
High performance
- The original XuperModel genuinely enables concurrent execution and verification of smart contracts.
- The TDPOS algorithm ensures fast consensus across large-scale node networks.
- A WASM virtual machine accelerated with AOT lets contracts run at speeds approaching native programs.
-
Greater security
- An account system protected by multiple private keys.
- Authentication supports flexible strategies such as weighted accumulation and set operations.
-
Easy scalability
- A robust P2P network supporting very large-scale nodes over wide-area networks.
- The underlying ledger supports fork management and automatic consistency convergence, enabling truly global deployment.
- Develop smart contracts in multiple languages
- Pluggable multi-language virtual machines powered by the original XuperBridge technology.
-
High flexibility
- A pluggable, modular design lets users easily choose the solution that fits their business scenario.
-

Chain Operations
-
Create a chain
./xchain-cli createChain
-
Start the service
nohup ./xchain &
-
Inspect blocks
./xchain-cli status -H 127.0.0.1:37101
-
Create an account
./xchain-cli account newkeys --output data/accounts/louis
-
Create a contract account
./xchain-cli account new --desc account.des The contract content is as follows:
{ "module_name": "xkernel", "method_name": "NewAccount", "args" : { "account_name": "1111111111111111", //Note: a string of 16 digits "acl": "{ "pm": {"rule": 1,"acceptValue": 0.6}, "aksWeight": {"AK1": 0.3,"AK2": 0.3}}" } }```
