Stateless Distributed Ledgers [PDF]

open access: yes, 2021
In public distributed ledger technologies (DLTs), such as Blockchains, nodes can join and leave the network at any time. A major challenge occurs when a new node joining the network wants to retrieve the current state of the ledger. Indeed, that node may receive conflicting information from honest and Byzantine nodes, making it difficult to identify ...

Stochastic Modelling of Selfish Mining in Proof-of-Work Protocols

open access: yesJournal of Cybersecurity and Privacy, 2022
In blockchain-based systems whose consensus mechanisms resort to Proof-of-Work (PoW), it is expected that a miner’s share of total block revenue is proportional to their share of hashing power with respect to the rest of the network.

A Serverless Distributed Ledger for Enterprises [PDF]

open access: yesProceedings of the Annual Hawaii International Conference on System Sciences, 2022
Enterprises have been attracted by the capability of blockchains to provide a single source of truth for workloads that span companies, geographies, and clouds while retaining the independence of each party's IT operations. However, so far production applications have remained rare, stymied by technical limitations of existing blockchain technologies ...

SoK: Communication Across Distributed Ledgers

open access: yes, 2021
Since the inception of Bitcoin, a plethora of distributed ledgers differing in design and purpose has been created. While by design, blockchains provide no means to securely communicate with external systems, numerous attempts towards trustless cross-chain communication have been proposed over the years.
