“…• Many related studies indicate that the throughput is more important than the latency in a Hyperledger-based system [18], [24]. • With the increase of the requests arrival rate, the system latency can grow infinitely while the throughput can reach a saturation point.…”

As a highly scalable permissioned blockchain platform, Hyperledger Fabric supports a wide range of industry use cases ranging from governance to finance. In this paper, we propose a model to analyze the performance of a Hyperledgerbased system by using Generalised Stochastic Petri Nets (GSPN). This model decomposes a transaction flow into multiple phases and provides a simulation-based approach to obtain the system latency and throughput with a specific arrival rate. Based on this model, we analyze the impact of different configurations of ordering service on system performance to find out the bottleneck. Moreover, a mathematical configuration selection approach is proposed to determine the best configuration which can maximize the system throughput. Finally, extensive experiments are performed on a running system to validate the proposed model and approaches.

Blockchain technologies are on the rise, and Hyperledger Fabric is one of the most popular permissioned blockchain platforms. In this paper, we re-architect the validation phase of Fabric based on our analysis from fine-grained breakdown of the validation phase's latency. Our optimized validation phase uses a chaincode cache during validation of transactions, initiates state database reads in parallel with validation of transactions, and writes to the ledger and databases in parallel. Our experiments reveal performance improvements of 2× for CouchDB and 1.3× for LevelDB. Notably, our optimizations can be adopted in a future release of Hyperledger Fabric.

Decentralization, in the form of mesh networking and blockchain, two promising technologies, is coming to the telecommunications industry. Mesh networking allows wider low-cost Internet access with infrastructures built from routers contributed by diverse owners, whereas blockchain enables transparency and accountability for investments, revenue, or other forms of economic compensations from sharing of network traffic, content, and services. Crowdsourcing network coverage, combined with crowdfunding costs, can create economically sustainable yet decentralized Internet access. This means that every participant can invest in resources and pay or be paid for usage to recover the costs of network devices and maintenance. While mesh networks and mesh routing protocols enable self-organized networks that expand organically, cryptocurrencies and smart contracts enable the economic coordination among network providers and consumers. We explore and evaluate two existing blockchain software stacks, Hyperledger Fabric (HLF) and Ethereum geth with Proof of Authority (PoA) intended as a local lightweight distributed ledger, deployed in a real city-wide production mesh network and in laboratory network. We quantify the performance and bottlenecks and identify the current limitations and opportunities for improvement to serve locally the needs of wireless mesh networks, without the privacy and economic cost of relying on public blockchains. KEYWORDS blockchain, Ethereum, Hyperledger Fabric, mesh networks, performance evaluation INTRODUCTIONNetwork infrastructures are critical to provide local and global connectivity that enables access to information, social inclusion, and participation for everyone. Local connectivity largely relies on access networks. Wireless mesh networks (WMNs) are a kind of access networks comprising of wireless nodes, namely wireless mesh routers, wireless mesh clients, and network gateways. A client (connected through WiFi or wired to a mesh router) can access the Internet across a WMN. 1 These are self-organized networks that can grow organically: new network links can expand the coverage of the network or increase the capacity when links get overused. The routing protocol runs in every router by measuring the performance and quality of links and coordinates distributed decisions about the best network paths periodically. As a result, once a routing protocol is adopted, the development and operation of the network only depends on pooling routers and links with local decisions, without any central planning or management.These decentralized networks are essential to develop community access networks, network infrastructure commons, built by citizens and organizations which pool their resources and coordinate their efforts, characterized by being open, free, and neutral. 2 These decentralized access networks have been identified as one way to connect the next billion people that are still without the Internet access. 3 Guifi.net* is an example of such a community effort, which is one of the biggest commun...
