The Challenge

The Ethereum network has seen a surge in usage, with over 177 million Ethereum addresses in existence and tens of thousands added each day. This high network usage, while signaling strong adoption, also points to a need for scalability and privacy-enhancing solutions. The challenge was to provide a solution that could handle the increasing demand for transactions on the Ethereum Mainnet and permissioned blockchains, while also ensuring privacy and confidentiality of transactions. The need for scalability was particularly pressing in areas such as decentralized finance (DeFi), non-fungible tokens (NFT), gaming, Web 3.0 and the metaverse, where the creativity of projects on Ethereum is exploding.

About The Customer

Consensys is the leading Ethereum software company, enabling developers, enterprises, and people worldwide to build next-generation applications, launch modern financial infrastructure, and access the decentralized web. Their product suite, composed of Infura, Quorum, Codefi, MetaMask, Truffle, Diligence and their NFT platform, serves millions of users, supports billions of blockchain-based queries for their clients, and has handled billions of dollars in digital assets. Ethereum is the largest programmable blockchain in the world, leading in business adoption, developer community, and DeFi activity. On this trusted, open source foundation, Consensys is building the digital economy of tomorrow.

The Solution

Consensys, in collaboration with Mastercard, launched Consensys Rollups, an innovative modular software solution for permissioned blockchain applications. This solution is designed to provide scalability and privacy capabilities that can be connected to any Ethereum Virtual Machine (EVM)-compatible blockchain. It can be used on the Ethereum Mainnet, or on private Consensys Quorum networks. Consensys Rollups leverage zero-knowledge (ZK) proofs to protect specific transaction elements, such as account balances, sender, recipient, and amount, to prevent this important transaction data from being shared publicly across the network. This significantly enhances the privacy and confidentiality of transactions. Solutions built with Consensys Rollups can currently achieve a throughput of up to 10,000 transactions per second (TPS) on a private chain.

Operational Impact

  • The implementation of Consensys Rollups has opened up new possibilities for blockchain use cases by increasing scalability and confidentiality for asset transfers. This includes Central Bank Digital Currencies (CBDCs), Decentralized Exchanges (DEXs), micropayments, and private transfer and taxes. For instance, CBDCs issuance on top of a Consensys Rollups powered Quorum network can provide scalability and privacy capabilities for digital currency transfers among central banks, commercial banks, and retail users. Similarly, DEXs built with Rollups will bring scalability to DeFi and NFTs, and more use cases on Ethereum that need faster settlement but the security guarantees of Ethereum. Furthermore, micropayment applications that require high throughput to properly function as large numbers of users interact with platforms and decentralized applications (dapps) will benefit from Rollups on mainnet. Finally, Consensys Rollups open a new pattern for confidentiality on the Ethereum Mainnet, or on Enterprise Ethereum (Quorum) powered networks, enabling use-cases that require auditability and transparency but also maintain user confidentiality.

Quantitative Benefit

  • Consensys Rollups can currently achieve a throughput of up to 10,000 transactions per second (TPS) on a private chain.

  • Only 300 TPS can be achieved on private chains and 15 on the Ethereum Mainnet without Consensys Rollups.

  • Consensys Rollups is compatible with all tokens that follow the ERC20 standard.

Case Study
Improving Production Line Efficiency with Ethernet Micro RTU Controller
Moxa was asked to provide a connectivity solution for one of the world's leading cosmetics companies. This multinational corporation, with retail presence in 130 countries, 23 global braches, and over 66,000 employees, sought to improve the efficiency of their production process by migrating from manual monitoring to an automatic productivity monitoring system. The production line was being monitored by ABB Real-TPI, a factory information system that offers data collection and analysis to improve plant efficiency. Due to software limitations, the customer needed an OPC server and a corresponding I/O solution to collect data from additional sensor devices for the Real-TPI system. The goal is to enable the factory information system to more thoroughly collect data from every corner of the production line. This will improve its ability to measure Overall Equipment Effectiveness (OEE) and translate into increased production efficiencies. System Requirements • Instant status updates while still consuming minimal bandwidth to relieve strain on limited factory networks • Interoperable with ABB Real-TPI • Small form factor appropriate for deployment where space is scarce • Remote software management and configuration to simplify operations

How Sirqul’s IoT Platform is Crafting Carrefour’s New In-Store Experiences
Carrefour Taiwan’s goal is to be completely digital by end of 2018. Out-dated manual methods for analysis and assumptions limited Carrefour’s ability to change the customer experience and were void of real-time decision-making capabilities. Rather than relying solely on sales data, assumptions, and disparate systems, Carrefour Taiwan’s CEO led an initiative to find a connected IoT solution that could give the team the ability to make real-time changes and more informed decisions. Prior to implementing, Carrefour struggled to address their conversion rates and did not have the proper insights into the customer decision-making process nor how to make an immediate impact without losing customer confidence.

Ensures Cold Milk in Your Supermarket
As of 2014, AK-Centralen has over 1,500 Danish supermarkets equipped, and utilizes 16 operators, and is open 24 hours a day, 365 days a year. AK-Centralen needed the ability to monitor the cooling alarms from around the country, 24 hours a day, 365 days a year. Each and every time the door to a milk cooler or a freezer does not close properly, an alarm goes off on a computer screen in a control building in southwestern Odense. This type of alarm will go off approximately 140,000 times per year, equating to roughly 400 alarms in a 24-hour period. Should an alarm go off, then there is only a limited amount of time to act before dairy products or frozen pizza must be disposed of, and this type of waste can quickly start to cost a supermarket a great deal of money.
