Unlocking more than one address:
sudo parity --config dev --geth --unlock "0x00a329c0648769a73afac7f9381e08fb43dbea72" --password ./parity-empty-pw.txt --jsonrpc-hosts any --jsonrpc-apis eth,net,private,parity,personal --ws-apis eth,net,private,parity,personal --jsonrpc-cors https://remix.ethereum.org
,"0x25fc28613d205f3c9ae0937827Ff6Ab07754e53a","0x7b9A6bf86BB7317DF7562106eCc45ad49acFaAeb","0x8C5D1Ad4BdA1AF6b93E027859c7424C65251F838","0xD420bd920789B19539316d1144B63539CD059152"
Enable unlocking with --geth flag
sudo parity --config dev --geth --unlock 0x00a329c0648769a73afac7f9381e08fb43dbea72 --password ./parity-empty-pw.txt --jsonrpc-hosts any --jsonrpc-apis eth,net,private,parity,personal --ws-apis eth,net,private,parity,personal --jsonrpc-cors https://remix.ethereum.org

- Problems with signing method of web3.js: It includes a hashing, which is not done in the ERC-865 token contracts. This leaded to different hashes and therefore different values.
- Not identical signature leaded to "random" address. Therefore a checking if from address is the same was included.
- The ERC-865 token contract (DOS token) always passes the from and the value parameter to the service contract. Therefore not every method of a contract can be called. Only the ones whose first parameters are _from (address) and _value (uint256)
This project was bootstrapped with Create React App.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Note: this is a one-way operation. Once you eject, you can’t go back!
If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
You can learn more in the Create React App documentation.
