How does a smart contract work?
A smart contract is a computerized transaction protocol that executes the terms of a contract. It works by translating contractual clauses into code, embedding them into property that can self-enforce them. Smart contracts are stored on the blockchain, have a unique address, and execute independently and automatically in a prescribed manner on every node in the network.

Does the 60/20/20 rule work?
I've heard about the 60/20/20 rule for managing finances, where 60% goes to expenses, 20% to savings, and 20% to investments or fun. I'm wondering if this rule really works in practice and if it's a good strategy to follow.

Does 50/30/20 work in London?
I'm wondering if the 50/30/20 budgeting rule, where 50% of income goes to needs, 30% to wants, and 20% to savings, would be effective in London. Considering the city's cost of living, can this approach still work?
