I am a solidity developer on ethereum. I had developed ERC20 tokens on ethereum and also have rich experience about this. And now, i am researching about smart contract on NEO blockchain. I want to work with you and i will do my best. first answer : I am an engineer and had developed a new cryptocurrency like as ethereum. if you want to see this, then i will show this. Ethereum system are include with bootnodes and nodes. When nodes startup first, then find a peers. If he can't find peers then he have to connect to bootnodes and find other peer's data. like this, on blockchain p2p was implemented. I was graduate the Qing Hwa university in china. Second answer : I had developed an ERC20 tokens on ethereum and a system like as DAO. And I mastered c++ and java. I think the Java is the best in OOP. Third answer : geth is the ethereum engine written by go language. geth supply ipc communication. geth opens ipc service when it is start. And if you write geth attach command then it does find the ipc service. Fourth answer : Smart contract is runned on EVM. if you build the solidity then it is converted into byte code. it is opcode. EVM analyses this opcodes and run it. best regards. thanks.
