On Orchestrating Parallel Broadcasts for Distributed Systems

The Chainlink Labs Research team introduces a concept called “ticketing” to enhance the orchestration of atomic broadcasts in distributed systems.

Exploring Consensus With Parallel Proposals: The Difference Between PBFT and BBCA-Chain

In this blog post, we explore sequential vs parallel consensus protocols and dive into a nuanced comparison between PBFT and BBCA-Chain.

Build It Super Simple: Introducing Single Broadcast Consensus on a DAG

The authors introduce BBCA-Chain—a single-broadcast DAG consensus protocol that simplifies DAG consensus with reduced latency by several network trips.

DECO Research Series #4: Hiding Secret Lengths

In this post, the Chainlink Labs Research team discusses how to hide the individual lengths of sensitive data from the verifier.

DECO Research Series #3: Parsing the Response

This post discusses how to efficiently parse the TLS response and form claims about it while preserving the privacy of sensitive data within the response.

Optimal Latency and Communication SMR View-Synchronization

Andrew Lewis-Pye, Dahlia Malkhi, and Oded Naor expand the discussion of view synchronization and present a new protocol that quickly recovers in the case of a Byzantine leader.

DECO Research Series #2: Provenance and Authenticity

Discover how the prover convinces the verifier that a TLS response is obtained from a particular server in Chainlink DECO.

DECO Research Series #1: Introduction

Introducing a blog series outlining the research taking DECO, a privacy-preserving oracle protocol, from idea to implementation.

DECO深度研究系列文章一:开篇

DECO不需要服务器端配合就可以运行。TLS服务器不需要做任何修改,甚至都不会意识到自己加入了DECO协议。这极大降低了DECO的采用门槛。

Realizing VOLE

Understand an efficient protocol to generate VOLE correlations for batches of commitments.
