This means that if we take an element from the abstract space, concretize it and abstract the concretized version, the result will be equal to the original. On the other hand, if you pick an element from the real space, abstract it and concretize the abstract version, the final result will be a super set of the original. That is,
Merkelized Abstract Syntax Trees (MAST) is a proposal by Johnson Lau which reduces the size of smart contracts (complex scripts), and increases their privacy. A 2006 paper by Mihir Bellare enables signature aggregation in O(1) size, which means that it will not take more space to have multiple signers.
The Extended UTXO (EUTXO) model is an advanced iteration of the traditional Unspent Transaction Output (UTXO) model. It expands on the fundamental UTXO model, incorporating enhanced features to increase flexibility and utility while maintaining the model's inherent advantages in security, predictability, and parallelizability.

In its first year, Canva had more than 750,000 users. [12] In April 2014, Guy Kawasaki joined the company as its chief evangelist. [13] In 2015, Canva for Work was launched, focusing on marketing materials. [14] During the 2016–17 financial year, Canva's revenue increased from A$6.8 million to A$23.5 million, with a loss of A$3.3 million. In ...
To overcome these shortcomings, taking a traditional database and adding blockchain features to it sounds more feasible. [6] That's how the concept of blockchain-based database came into existence, which consists of multiple member clouds riding on two primary layers; the first one is Database Interface and the second one is the Blockchain ...
In computing, an abstraction layer or abstraction level is a way of hiding the working details of a subsystem. Examples of software models that use layers of abstraction include the OSI model for network protocols, OpenGL, and other graphics libraries, which allow the separation of concerns to facilitate interoperability and platform independence.
Abstraction may be exact or faithful with respect to a property if one can answer a question about the property equally well on the concrete or abstract model. For instance, if one wishes to know what the result of the evaluation of a mathematical expression involving only integers +, -, ×, is worth modulo n , then one needs only perform all ...
Blockchain has been acknowledged as a way to solve fair information practices, a set of principles relating to privacy practices and concerns for users. [5] Blockchain transactions allow users to control their data through private and public keys, allowing them to own it. [5] Third-party intermediaries are not allowed to misuse and obtain data. [5]
