“…We evaluate the proposed improvements to the NeoGo gossip module and compare the results with the original version of the module implementation. Inspired by [1], we mainly focus our assessment on the three key metrics described above: block non-delivery probability, block propagation latency, and traffic load (also called bandwidth utilization), and how these metrics correlate with each other.…”

“…Most gossip optimization algorithms (such as those presented in [1] and [2]) require local peer-to-peer access to global network information. This is a separate issue known as the aggregation problem [7] and refers to a set of functions that provide access to such distributed system components as network size, load average and uptime, network map, and so on.…”

Peer-to-peer (P2P) networks, together with other distributed systems, must meet strict efficiencyrequirements in terms of the information dissemination process. Rapid message transmission affectsthe entire functionality of the network, including data processing, attack resistance, topology changes,etc. In this article, we look at the most common network protocols based on gossip, explore andcompare several approaches to improve the information dissemination model. We describe the Neoblockchain network protocol, which extends gossip algorithms to distribute messages over a P2Pnetwork. Based on the simulation results, we build a model of the Neo blockchain network protocoland evaluate the effectiveness of the Neo network protocol in terms of reactive message processing inseveral scenarios, propose protocol improvements and evaluate the resulting performance gain.

“…To address the heterogeneity in workload/bandwidth, one popular approach is gossip [55], [56], [15]: the broadcaster randomly picks some of its peers and sends them the message, and the receivers repeat this process until all the nodes receive the message with high probability. Despite their scalability, gossip protocols have a long tail-latency (the time required for the last node to receive the message) and high redundancy.…”

Devouring the Leader Bottleneck in BFT Consensus

There is a resurgence of interest in Byzantine faulttolerant (BFT) systems due to blockchains. However, leaderbased BFT consensus protocols used by permissioned blockchains have limited scalability and robustness. To alleviate the leader bottleneck in BFT consensus, we introduce Stratus, a robust shared mempool protocol that decouples transaction distribution from consensus. Our idea is to have replicas disseminate transactions in a distributed manner and have the leader only propose transaction ids. Stratus uses a provably available broadcast (PAB) protocol to ensure the availability of the referenced transactions. To deal with unbalanced load across replicas, Stratus adopts a distributed load balancing protocol that is co-designed with PAB.We implemented and evaluated Stratus by integrating it with state-of-the-art BFT-based blockchain protocols and evaluated these protocols in both LAN and WAN settings. Our results show that Stratus-based protocols achieve up to 5 ∼ 20× more throughput than their native counterparts in a network with hundreds of replicas. In addition, the performance of Stratus degrades gracefully in the presence of network asynchrony, Byzantine attackers, and unbalanced workloads. Our design provides easy-to-use APIs so that other BFT systems suffering from leader bottlenecks can use Stratus.

“…P2P protocols support technical decentralization, and use communication patterns which do not require Quality-of-Service (QoS) contracts or Service Level Agreements between blockchain network participants. Even permissioned DLT implementations use prob-abilistic protocols: for example, Hyperledger Fabric uses the so-called gossip protocol [20].…”

Railway operations require control systems to ensure safety and efficiency, and to coordinate infrastructure elements such as switches, signals and train protection. To compete with the traditional approaches to these systems, a blockchainbased approach has been proposed, with the intent to build a more resilient, integrated and cost-efficient system. Additionally, the developed blockchain-based architecture enables to run safety-relevant and security-focused business logic on off-the-shelf platforms such as cloud, rather than on specialized (and expensive) secure hardware. After implementing a prototype of the blockchain-based railway control system, scaling the approach to real-world mainline and branch operations required a thorough validation of the design choices. In this technical report, we show how performance calculations, long-term technology perspectives and law-mandated norms have impacted the architecture, the technology choices, and the make-buy-reuse decisions.
