What are trustless technologies?

"Trustless" technologies refer to systems and protocols that operate without requiring the trust of users in any singular entity or intermediary. They ensure that users can trust the system's outcomes without relying on any central authority or middleman.

One key aspect of trustless technologies is the use of cryptographic methods and decentralized networks. For instance, in the world of cryptocurrencies and blockchain, these technologies enable the execution of transactions and smart contracts directly between participants, verified by a decentralized network, thus removing the need for trusted third parties.

Examples of trustless technologies include:

1. Bitcoin and Ethereum: These blockchain-based platforms allow for the trustless issuance and settlement of digital assets. Transactions are verified by a decentralized network of nodes, not any single entity 1.

2. SGX (Software Guard Extensions): This technology from Intel creates isolated, protected enclaves within processors, allowing for secure and verifiable computation. Even the person running the computation cannot tamper with the process, and it provides proofs to ensure integrity and prevent unauthorized access 2.

3. Ethereum Applications: These can range on a spectrum from highly trustless, like Uniswap, which requires no human intervention, to more trusted systems where some level of human maintenance or oversight is required. This spectrum illustrates varying degrees of trust needed in the operation of these applications 1.

4. Decentralized Finance (DeFi): DeFi platforms leverage smart contracts on blockchains like Ethereum to provide financial services without intermediaries, ensuring transparency and security 3.

5. Zero-Knowledge Proof (ZKP) Technologies: These allow individuals to prove their trustworthiness or certain attributes about themselves without revealing additional information, enhancing privacy and security in decentralized systems 4.

These technologies are fundamental in creating systems where users do not need to rely on the veracity of any single party but can still trust the system as a whole.
