Let’s get one thing straight: trustless doesn’t mean not trustworthy. A trustless system is designed to operate without relying on trust in people or institutions. It’s a self-sufficient, autonomous system that can verify transactions and make sure everything is legit, all without any need for human intervention.

This means that you can rest easy knowing that the system is working as it should, regardless of who is behind the scenes. There is no need to worry about people with their own agendas, making mistakes or being dishonest — the trustless system has got it all under control.

In traditional systems, you need trust to make sure everyone involved in a transaction is being honest. But in a trustless system, you don’t need to rely on anyone’s word or reputation because the system is designed to work without the need for trust.

I don’t understand… How trust is needed in traditional systems?

As an example, the banking system is a world built on trust. Depositors and borrowers alike must place their faith in the hands of financial institutions.

When you deposit your hard-earned cash into a bank, you’re entrusting it to a group of individuals you may never meet, hoping they’ll keep it safe and sound. The banking system needs trust because if people don’t trust banks to keep their money safe, they will not deposit their money in the bank. Additionally, if people don’t trust banks to give them access to their money when they need it, they will not use the bank’s services.

Likewise, when you borrow money, you’re counting on the bank to trust that you’ll pay it back in full and on time. If banks don’t trust their borrowers to repay their loans, they will not lend money to them. This trust is the glue that holds the banking system together, and without it, the whole structure would crumble.

Trust is essential in the banking system because it creates a level of confidence that the system will work as intended and that everyone involved will act in good faith. Imagine a world where people were skeptical of depositing their savings or reluctant to lend money. The banking system, as we know it, would cease to function, and chaos would reign.

How does a trustless system work without trust?

Imagine a system that runs on its own without any human intervention. This system has a set of rules and protocols built into its code that dictate how it should function and what actions it should take in response to different inputs or events.

Now, let’s say you want to use this system to do something, like sending money. You follow the rules, and the machine automatically verifies your transaction using complex algorithms and cryptography.

One example of this kind of system is Bitcoin, a trustless cryptocurrency. When someone wants to send Bitcoin to someone else, they create a transaction that is broadcasted to the Bitcoin network. The transaction is verified by a network of computers, known as nodes, using complex algorithms that ensure the transaction is legitimate. Once the transaction is verified, it is added to a block of transactions that are cryptographically linked to the previous block in a chain, hence the name “blockchain.” This creates an immutable record of all the transactions on the network, making it almost impossible to manipulate the system.

By removing the need for trust in people or institutions, a trustless system creates a more transparent, secure, and reliable way of operating because the system itself verifies and enforces the rules. This makes the system not dependent on any one person or organization to ensure its proper functioning.
