Exploiting Multi-Core Parallelism in Blockchain Validation and Construction
Arivarasan Karmegam, Lucianna Kiffer, Antonio Fernández Anta
Blockchain validators can reduce block processing time by exploiting multi-core CPUs, but deterministic execution must preserve a given total order while respecting transaction con…
Setchain Algorithms for Blockchain Scalability
Arivarasan Karmegam, Gabina Luz Bianchi, Margarita Capretto +3
Setchain has been proposed to increase blockchain scalability by relaxing the strict total order requirement among transactions. Setchain organizes elements into a sequence of sets…
Auditable Shared Objects: From Registers to Synchronization Primitives
Hagit Attiya, Antonio Fernández Anta, Alessia Milani +2
Auditability allows to track operations performed on a shared object, recording who accessed which information. This gives data owners more control on their data. Initially studied…
A Decentralized Sequencer and Data Availability Committee for Rollups Using Set Consensus
Margarita Capretto, MartÃn Ceresa, Antonio Fernández Anta +2
Blockchains face a scalability challenge due to the intrinsic throughput limitations of consensus protocols and the limitation in block sizes due to decentralization. An alternativ…
Fast and Secure Decentralized Optimistic Rollups Using Setchain
Margarita Capretto, MartÃn Ceresa, Antonio Fernández Anta +2
Modern blockchains face a scalability challenge due to the intrinsic throughput limitations of consensus protocols. Layer 2 optimistic rollups (L2) are a faster alternative that of…
