Blockchain based Smart Contracts

Looking for programmers to build Templated Smart Contracts. In essence, once proof of concept is completed I will require multiple updates and ongoing support. The initial round (proof-of-function/concept) will need to use the Blockchain's security protocols. We will need the ability to create multiple contracts in the future. I would want to save a cryptographic signature of a document or file on a Blockchain and retrievable by the recipient of the contract only. Here's an example:

1. Salesperson A uses a link to log into a secure area. That salesperson completes a contract.

2. The data uses a cryptographic signature and is stored as a file (ideally) on a blockchain.

3. The company the salesperson works for receives instant notification and is subsequently able to decrypt the data and process it accordingly.

Build using Ethereum virtual machine (EVM). EVM is the runtime environment for smart contracts, and every node in the Ethereum network runs Let's discuss.s an EVM implementation and executes the same instructions. Solidity, as a high-level programming language, is used to write smart contracts, and the contract code is compiled down to EVM bytecode and deployed on the blockchain for execution.

Habilidades: Contratos, Arquitetura de software, Python, Solidity, Ethereum
