The modern-day expectations of a Turing computer capable of solving all computational problems.

Turing Complete is the term used to describe still-futuristic machines or algorithms that can solve all computational problems, regardless of their levels of complexity. Such machines only require time and sufficient processing power. In blockchain, these machines are used to determine the level of network complexity and operation, which also indicates the efficiency of the blockchain for carrying out tasks.

Turing Complete is not necessarily sought-after in blockchain applications since it also has limitations. Thus, Bitcoin, for example, is Turing Incomplete, thereby keeping the blockchain somewhat straightforward. On the other hand, Ethereum uses Turing Complete mostly because it requires higher accuracy and complexity for its smart contracts.


UTXO is an acronym for: unspent transaction output.

One of the characteristics of blockchain networks in which users don’t have to know or trust one another for the network to work.

Trustless is a definitive characteristic of the decentralized model of finance that derives system authority from algorithms rather than human beings. These algorithms serve as unbiased mediators during transactions between and among users, such that the users don’t have to know or trust themselves to engage in transactions. As a consequence, blockchain networks are reliable and not subject to user bias and partiality.

The main characteristic of a trustless system is the replacement of a central authority in the form of human agents with algorithms. This is not the case with centralized systems but are the defining attributes of decentralized systems.
