AISChain is a secure and fast blockchain-based AIS data platform. AISChain adopts to participate in the consensus protocol, and is compatible with current commodity AIS hardware. Since the whole system is co-maintained by multiple authorized parties, AISChain can integrate AIS data resources in a secure way. For avoiding repeated recording of AIS data on the chain, we design the Dynamic Bloom Filter Tree (DBFT) to realize efficient duplication detection in the transaction verification phase. Here we implement a prototype of AISChain, and conduct extensive experiments to evaluate the performance of AISChain. Evaluation results show that the search time of DBFT is negligible (4.3 ms) with an extreme low error ratio (0.4%). Meanwhile, AISChain can achieve more than 730 tx/s throughput even when nodes scale to 36. To the best of our knowledge, AISChain is the first work to apply the blockchain technology to secure the AIS data platform.
The benchmark:
- Provide a prototype of AISChain and a quick start demo.
- Provide complete realization of Dynamic Bloom Filter Tree (DBFT).
- Provide contract compilation function, convert Solidity contract files into Java contract files.
- Provide transfer pressure test Demo.
- Provide AMOP test Demo.
- Provide CRUD contract stress test Demo.
- Linux OS
- JAVA SDK 14
Compile source code
# clone the source code
$ git clone https://github.com/1570005763/AISChain.git
$ cd AISChain
# (optional) format java file if code changes
$ ./gradlew googleJavaFormat
# compile the source code
$ ./gradlew buildAISChain Demo
# This is a quick start of AISChain demo, where you can run entire AISChain and see outcome in a few steps.
# build AISChain (this command will stop and delete current chain if one is running).
$ cd fisco
$ bash AISChain.sh
# run AISChain demo.
$ cd ../dist
$ bash run_AISChain.shConfigure Java SDK Demo
Before using the Java SDK Demo, you must first configure the Java SDK, including certificate copy and port configuration. For details, please refer to here.
# bash
# Copy the certificate (suppose the SDK certificate is located in ~/fisco/nodes/127.0.0.1/sdk directory)
$ cp -r ~/fisco/nodes/127.0.0.1/sdk/* conf
# Copy configuration file
# Note:
# The channel port of the FISCO BCOS blockchain system built by default is 20200.
# If you modify this port, please modify the [network.peers] configuration option in config.toml
$ cp conf/config-example.toml conf/config.toml
Execute stress test Demo
Java SDK Demo provides a series of stress testing programs, including serial transfer contract stress testing, parallel transfer contract stress testing, AMOP stress testing, etc. The specific usage examples are as follows:
# bash
# Enter the dist directory
$ cd dist
# Copy the sol file that needs to be converted to java code to the dist/contracts/solidity path
# convert sol, where ${packageName} is the generated java code package path
# The generated java code is located in the /dist/contracts/sdk/java directory
$ java -cp "apps/*:lib/*:conf/" org.fisco.bcos.sdk.demo.codegen.DemoSolcToJava ${packageName}
# Pressure test PerformanceOk contract:
# count: total transaction count
# tps: qps
# groupId: the group ID
$ java -cp 'conf/:lib/*:apps/*' org.fisco.bcos.sdk.demo.perf.PerformanceOk [count] [tps] [groupId]
# Pressure test parallel transfer contract
# --------------------------
# Add accounts based on the Solidity parallel contract parallelok:
# groupID: the group ID

$ java -cp 'conf/:lib/*:apps/*' org.fisco.bcos.sdk.demo.perf.ParallelOkPerf [precompiled] [groupID] [add] [count] [tps] [file]
# --------------------------
# Based on the Solidity parallel contract parallelok to initiate a transfer transaction stress test
