PKI for busy people

Public-key infrastructure (PKI) is an umbrella term for everything that has to do with keys and certificates.

This is a quick overview of the important stuff.

Public-key cryptography

Public-key cryptography involves a key pair: a public key and a private key. Each entity has their own. The public key can be shared around, the private key is secret.

Description.

ERC20 is the most common Ethereum token standard. It should be noted that it is also the first Ethereum's token standard as well.

It is also important that the original ERC20 proposal is a definition of token interface. EIP20 does not define a reference implementation for this token standard. Here is OpenZeppelin implementation of ERC20 token: https://github.com/OpenZeppelin/zeppelin-solidity/tree/master/contracts/token/ERC20

ERC20 token standard implementation assumes two ways of token transferring: (1) transfer function and (2) approve + transferFrom pattern.

I agree the point you’re making here, 100%. However, a slight correction about Node’s APIs.

First of all, process.nextTick is actually first in, first out. Proof:

$ node -e 'process.nextTick(console.log.bind(console, 1)); process.nextTick(console.log.bind(console, 2))'
