 The PoD consensus + XPZ public chain helps Ethereum increase network transaction speed and reduce Gas fees. At the same time, the introduction of the EVERNET permanent storage network can provide decentralized permanent storage space for financial infrastructure, the Internet of Things, and the Internet.

 XPZ mining machine is based on the dual-core mining mode of Nvdia and AMD. Based on the special structure of PoD, XPZ can conduct joint mining with ETH, which saves energy and achieves the goal of carbon neutrality on the chain.
 
 After XPZ upgrades the perpetual storage network, large-scale on-chain low-cost storage can be realized, which provides a guarantee for permanent storage of data by facilitating hard disk storage space.

XPZ, under the joint promotion of many geek technology enthusiasts and teams around the world, actively explores the new Ethereum The road to expansion.
 
 The XPZ (full name HyperCube) public chain supports large-scale, multi-threaded, multi-concurrent network computing and storage capabilities such as NFT casting, social tokens, DeFi, and financial applications.

+# Code Coverage
+
+To generate code coverage statistics:
+
+```bash
+$ scripts/coverage.sh
+$ open target/cov/lcov-local/index.html
+```
+
+Why coverage? While most see coverage as a code quality metric, we see it primarily as a developer
+productivity metric. When a developer makes a change to the codebase, presumably it's a *solution* to
+some problem. Our unit-test suite is how we encode the set of *problems* the codebase solves. Running
+the test suite should indicate that your change didn't *infringe* on anyone else's solutions. Adding a
+test *protects* your solution from future changes. Say you don't understand why a line of code exists,
+try deleting it and running the unit-tests. The nearest test failure should tell you what problem
+was solved by that code. If no test fails, go ahead and submit a Pull Request that asks, "what
+problem is solved by this code?" On the other hand, if a test does fail and you can think of a
+better way to solve the same problem, a Pull Request with your solution would most certainly be
+welcome! Likewise, if rewriting a test can better communicate what code it's protecting, please
+send us that patch!

+persons and that transactions with such persons would be a violation of
+U.S. export controls and sanctions law. This risk applies to
+individuals, organizations, and other ecosystem participants that

+(e.g., as a node operator), and individuals that transact on the HyperCube
+blockchain through light clients, third party interfaces, and/or wallet
