# Ethereum & Blockchains Bitcoin solves the task of storing and transferring value. But there are other tasks: deposits, exchanges, agreements — even more complex interactions where the logic is set in the contract. Now if something went wrong in the collaboration of the parties, the courts get involved. Some courts work better, others worse, but the review of disputes can take years. The rules may not always be created in a transparent way, and people have little ability to influence the rules. > Laws serve those who make the laws. This is where the element of the system comes in. Ethereum is a platform for writing smart contracts — the rules for human or robot interaction. More money = often more opportunities. For example, more financial tools are available to accredited investors. Anyone can create their own scripts/smart contracts on the Ethereum blockchain for any purpose. A lot of people in the world [don't even have access to the financial system](#user-content-fn-1)[^1] to earn a return on their savings. And this is being transferred to an open platform (ETH) for all to use. Ethereum solved the problem of smart contracts. But it was very expensive. Alternatives began to appear, trying to solve the same task. For example, Solana — transactions are cheaper and easier to experiment. The well-known Avalanche, Polkadot, NEAR Protocol, and Cosmos are all digging in the direction of smart contracts. Blockchains (primarily ETH and others like it) enable humans and robots to make deals without intermediaries in a transparent, publicly visible way.
