Lumiere: Making Optimal BFT for Partial Synchrony Practical
Andrew Lewis-Pye, Dahlia Malkhi, Oded Naor +1
The view synchronization problem lies at the heart of many Byzantine Fault Tolerant (BFT) State Machine Replication (SMR) protocols in the partial synchrony model, since these prot…
Grassroots Flash: A Payment System for Grassroots Cryptocurrencies
Andrew Lewis-Pye, Oded Naor, Ehud Shapiro
The goal of grassroots cryptocurrencies is to provide a foundation with which local digital economies can emerge independently of each other and of global digital platforms and glo…
Flash: An Asynchronous Payment System with Good-Case Linear Communication Complexity
Andrew Lewis-Pye, Oded Naor, Ehud Shapiro
While the original purpose of blockchains was to realize a payment system, it has been shown that, in fact, such systems do not require consensus and can be implemented determinist…
Rethinking Block Storage Encryption with Virtual Disks
Danny Harnik, Oded Naor, Effi Ofer +1
Disk encryption today uses standard encryption methods that are length preserving and do not require storing any additional information with an encrypted disk sector. This signific…
Cordial Miners: Fast and Efficient Consensus for Every Eventuality
Idit Keidar, Oded Naor, Ouri Poupko +1
Cordial Miners are a family of efficient Byzantine Atomic Broadcast protocols, with instances for asynchrony and eventual synchrony. They improve the latency of state-of-the-art DA…
On Payment Channels in Asynchronous Money Transfer Systems
Oded Naor, Idit Keidar
Money transfer is an abstraction that realizes the core of cryptocurrencies. It has been shown that, contrary to common belief, money transfer in the presence of Byzantine faults c…
Byzantine Agreement with Less Communication: Recent Advances
Shir Cohen, Idit Keidar, Oded Naor
In recent years, Byzantine Agreement is being considered in increasing scales due to the proliferation of blockchains and other decentralized financial technologies. Consequently,…
All You Need is DAG
Idit Keidar, Eleftherios Kokoris-Kogias, Oded Naor +1
We present DAG-Rider, the first asynchronous Byzantine Atomic Broadcast protocol that achieves optimal resilience, optimal amortized communication complexity, and optimal time comp…
Expected Linear Round Synchronization: The Missing Link for Linear Byzantine SMR
Oded Naor, Idit Keidar
State Machine Replication (SMR) solutions often divide time into rounds, with a designated leader driving decisions in each round. Progress is guaranteed once all correct processes…
Cogsworth: Byzantine View Synchronization
Oded Naor, Mathieu Baudet, Dahlia Malkhi +1
Most methods for Byzantine fault tolerance (BFT) in the partial synchrony setting divide the local state of the nodes into views, and the transition from one view to the next dicta…
Teechain: A Secure Payment Network with Asynchronous Blockchain Access
Joshua Lind, Oded Naor, Ittay Eyal +3
Blockchains such as Bitcoin and Ethereum execute payment transactions securely, but their performance is limited by the need for global consensus. Payment networks overcome this li…
