Descripción del proyecto
Protocolos de segunda capa para la escalabilidad y confidencialidad de las cadenas de bloques
En el mundo de las tecnologías de cadena de bloque, los sistemas descentralizados deberían poder competir con las plataformas centralizadas. Dado que las tecnologías de cadena de bloque prometen grandes beneficios en los ámbitos de la seguridad, la libertad y la eficiencia, es importante abordar sus deficiencias y superar sus retos. En este contexto, el equipo del proyecto CRYPTOLAYER, financiado por Consejo Europeo de Investigación, creará tecnologías fuera de la cadena que formarán un protocolo seguro de segunda capa sobre la cadena de bloques subyacente. En concreto, una familia de protocolos seguros para sistemas de transacciones fuera de la cadena trasladará enormes cantidades de transacciones a una segunda capa, lo que ofrecerá una escalabilidad casi ilimitada y un procesamiento instantáneo de las transacciones. Esta innovación es compatible con contratos inteligentes y ofrece unas sólidas garantías de privacidad al basarse en herramientas procedentes de la criptografía. Una función adicional es aprovechar los protocolos de segunda capa para mejorar la confidencialidad y la funcionalidad de los sistemas de cadena de bloques.
Objetivo
Blockchain technologies offer an exciting new alternative for centralized platform providers. They distribute trust over a large number of parties, thereby promising major benefits in terms of security, freedom and efficiency. Unfortunately, due to their inherent distributed nature, state of the art blockchains suffer from a multitude of shortcomings. In contrast to centralized platforms, they are restricted in terms of scalability, confidentiality and functionality, and thus cannot power large scale applications. The ambitious goal of CRYPTOLAYER is to overcome this situation by building decentralized systems that can compete with centralized platforms. We will achieve this goal via building off-chain technologies that form a secure second protocol layer on top of the underlying blockchain.
The first component of CRYPTOLAYER builds a family of secure protocols for off-chain transaction systems. These protocols move the massive amount of transactions to a second layer, thereby offering nearly unlimited scalability and instantaneous transaction processing. Our solutions will support smart contracts - complex programs that can handle money - and offer strong privacy guarantees by relying on tools from cryptography. The second component of CRYPTOLAYER leverages advanced cryptographic building blocks to construct secure off-chain services for confidentiality and access to real-world data. This will enable rich classes of applications to run over decentralized infrastructures. Finally, since secure protocol design is highly involved and error-prone, we will build upon the formal framework of theoretical cryptography. We will develop formal security models using the universal composability framework, and carry out a rigorous security analysis using mathematical proofs. With our overarching treatment of off-chain technologies, our vision is to establish this field as a central part of the rapidly evolving research on blockchain technologies.
