Two contrasting architectural models in software deployment are Multi-Tenancy and Single-Tenancy. In cloud computing and Software-as-a-Service (SaaS) environments, Multi-Tenancy allows multiple tenants to share the underlying infrastructure, optimizing resource utilization and reducing overall expenses for individual tenants. In contrast, Single-Tenancy allocates a dedicated instance of the software application to each customer, operating in isolation with its own set of resources.

Single-Tenant vs. Multi-Tenant Architectures

The Secret Network, a public blockchain protocol centered on privacy-preserving smart contracts, offers a valuable solution for implementing Multi-Tenancy within the manufacturing industry. By harnessing the privacy features inherent in the Secret Network, the manufacturing sector stands to gain significantly from the establishment of cost-efficient, secure, and private data-sharing mechanisms among various stakeholders, including suppliers, manufacturers, and customers.

Distributed Ledger and Blockchain Technology

The progression of Distributed Ledger Technologies (DLTs), with blockchain being a notable type, has undergone a substantial transformation in its architecture and applications. This overview traces the evolution of blockchain from Single-Tenant solutions on public networks to the rise of private permissioned networks and the present state where public networks can facilitate multi-tenancy.

Secret Network Overview

The Secret Network, a public blockchain protocol, offers a comprehensive solution for implementing multi-tenancy in the manufacturing industry. It provides privacy-preserving smart contracts, programmable privacy, and a developer-friendly infrastructure, positioning it as an optimal choice for implementing multi-tenancy in the manufacturing sector.

Viewing Keys in Secret Network

Viewing keys, cryptographic tools that enable authorized users to access encrypted data, serve as a means of access control. They allow individuals to securely view specific data, assets, or content while preserving the overall privacy and confidentiality of the information. The owner of the corresponding private key creates a viewing key, which can be shared with trusted parties or applications but can also be revoked, providing a mechanism for controlled and secure data access.

Example of a transaction which can be read with the correct viewing key but stays encrypted when entering the wrong key

Conclusion

The integration of multi-tenancy within the manufacturing industry, particularly on the Secret Network, harnesses advanced blockchain features and cryptographic tools to achieve cost efficiency, streamlined data access, enhanced resource utilization, flexibility, and collaboration. The strategic use of viewing keys as an access control mechanism enhances the security and privacy of shared data, making it a valuable asset in managing user access within a multi-tenancy framework on the Secret Network.

In addition to Datarella, the consortium consisted of Schwäbische Werkzeugmaschinen, the Institute for Control Engineering of Machine Tools and Manufacturing Equipment (ISW), the Frankfurt School Blockchain Center, inovex, ONDICS, Schütte, and Asys Group.

KOSMoS worked to develop a collaborative platform for small and medium-sized companies (SMEs) in the manufacturing sector based on distributed ledger technology (DLT). DLT is a family of innovative, decentralized technologies with blockchain technology being the most popular member of the family. Within the KOSMoS project, two different industrial use cases were realized on a DLT-based platform: 1) dynamic leasing, and 2) transparent maintenance.

The primary goal of KOSMoS was to develop a platform for the cross-company networking of production and process data using blockchain technology. The platform is able to integrate new offerings and business models. Examples include transparent maintenance concepts, dynamic leasing, and proof of quality for delivered products. Through these business models, all cooperating companies should gain an advantage. Examples of such improvements include lower prices, lower maintenance costs, and easier product distribution. In summary, the project should facilitate better cooperation amongst companies in the industry sector.

The Hyperledger Fabric DLT used in this project was part of the following logical system, where most of the individual components are accessible over standardized ports, and others were only available in private networks:

The final results of KOSMoS were presented at a full-day workshop in March including all three initiatives of the InKoWe association.

We from Datarella were very proud to be part of this innovative research project and happy to make a major contribution to the consortium with its DLT experience.

There are currently two major types of Verifiable Credentials used in the SSI world that implement different cryptography schemes and have different capabilities. However, both are perfectly fine to implement working SSI use cases.

The first type is based on the “Camenisch-Lysyanskaya ZKP” signature scheme, or short CL-Signatures, to issue so-called Anoncreds. It is used in SSI projects that implement Hyperledger Indy, a DLT with an SDK that was created specifically for SSI use cases and with support of the Aries Protocol. The popular Aries Cloud Agent Python is implementing these kinds of Verifiable Credentials and therefore a lot of existing SSI use cases are using Anoncreds.

The second type are JSON-LD credentials which is recommended as a standard by the W3C. It comes from an ledger independent approach and relies more on semantics which allow for a broader ecosystem interoperability. This approach is preferred among the Aries Framework Go ecosystem. 

If you want to learn more about different credential types, take a look at the article “Categorizing Verifiable Credentials” from Evernym and the paper from Kalyia Young called “Verifiable Credentials Flavors Explained”.

One major problem is that these two types of Verifiable Credentials are not compatible with each other as they are using different cryptography determined by the ecosystem they are residing in. Therefore, Datarella aims to make Anoncreds available to the Aries Framework Go to get the best of both worlds. This allows for deploying agents on non-mobile edge devices while being compatible with solutions built on the Aries Cloud Agent Python or Hyperledger Indy, respectively.

We decided to write a wrapper of the indy-credx library in Go. This allows us to call the indy-credx functions for credential management from a Go environment, such as a vehicle or a mobile device. Our pull request was successfully merged in the shared rust libraries and is now openly accessible by others. However, this was just the first step. In the next step, we will integrate the wrapper with the Aries Framework Go to simplify the integration from that side. 

Stay tuned for when we are giving a progress report on the Aries Bridge again in our News section; e.g. leveraging it for the mobility space in our moveID Gaia-X project.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme within the framework of the eSSIF-Lab Project funded under grant agreement No 871932.

Feel invited to watch our demo, which will provide you more information on the background of the Rohingya Archive and its current features.

R-Archive Demo Video

The post Building the Rohingya Archive (Demo Video) appeared first on DATARELLA.

We are happy to announce that Datarella teamed up with the Rohingya Project, and researchers from UCLA and CUNY to build the Rohingya Archive (R-Archive). The R-Archive is a decentralized digital heritage archive to preserve the endangered legacy of the stateless Rohingya people. Documents will be stored permanently and securely encrypted on the decentralized storage network Arweave.

The Rohingya People

The term, Rohingya people, describes an ethical group, originated in Rakhine State, Myanmar, previously known as Burma. In 1982, Myanmar’s government decided to deny citizenship to the predominantly Islamic Rohingya minority. In 2016, the Rohingya people were forced to flee their home country to escape the genocide through Myanmar’s armed forces and police. Now, the remaining Rohingya people are dispersed mainly over Bangladesh, India, Pakistan, Thailand, Indonesia and Saudi Arabia. 

The situation of Rohingya people stays problematic. Many are living in refugee camps and are not granted a legal identity by their hosting governments. Without a legal identity, many do not have access to public services, like schooling and insurance, and are not allowed to work. The absence of a legal status results in immense barriers to creating a brighter future for the Rohingya community.  

If there would be just proof of their legal claims?

The immutable Rohingya-Archive 

There are still old passports and documents distributed among members of the Rohingya community. The R-Archive is meant as a decentralized tool for preserving the Rohingya legacy.

It serves three main purposes:

1. As a heritage and cultural archive for anthropologists and researchers.
2. As a community archive for the distributed Rohingya people. 
3. As a trustworthy evidence archive for legal proceedings.    

Rohingya documents, which are uploaded to the R-Archive, will be preserved forever.

Forever?
Yes, because the R-Archive is connected to Arweave, a decentralized storage protocol. Our web app allows uploading securely encrypted and systematically tagged Rohingya documents to the “Blockweave”. The Blockweave (take a deep breath) is a blockchain-inspired, open & permissionless (=censorship resistance) data structure, which allows storing vast amounts of data permanently at low cost.

Okay, okay, let’s take this bite by bite.
A blockchain for data storage? Yes, you are right, normally you don’t store vast amounts of data on a blockchain. That’s the case because, with “normal” Blockchains, every node stores the complete chain, from the first to the latest block. This results in very high costs for storage. Storing 1 MB on Ethereum would set you back at least 5000USD in gas fees. In contrast, storing a 1 MB on Arweave will cost you only less then 0,03 USD in $AR.

How?
Blockweave data structure allows nodes of the network to only store an arbitrary size of the data set on their machine. The total weave size doubled in the last month from 10 to 20TB. If the growth continues, it is likely that individual miners only store a small fraction of the whole weave. However, Arweave’s consensus algorithm, incentivizes miners to replicate data sets as often as possible. The more data a miner stores of the weave, the higher is her chance of mining the next block and earning rewards.

To store data permanently, a fee is paid in $AR. The majority of AR transaction costs go into an endowment value, which is released over time to the miner. This, in combination with a very conservative estimation of the development of storage costs, allows permanent storage.

But let’s go back to the R-Archive and save the mind-blowing details of the Arweave technology for an R-Archive tech deep-dive blog post.

The R-Archive Partners

The R-Archive is a collaboration between the three partners and an MVP is built with a grant provided by the Arweave Foundation. Thank you <3.

Rohingya Project, a humanitarian organization, based in Kuala Lumpur, which is empowering refugees, leveraging innovative technologies, such as blockchain. You might know them already from our joint R-Coin project. The R-Project, led by Noor Muhammad and Saqib Sheikh, who initiated the R-Archive. Further, they provide and train field officers who are collecting Rohingya documents in Bangladesh, Saudi Arabia and Malaysia, as well as the scanning and indexing.

University researchers, Anne Gilliland from Center for Information as Evidence, UCLA and James Lowry from the Archival Technologies Lab, Queens College, City University of New York. Our academic partners created a guide for compliant data collection and a metadata standard, which allows us to index collected Rohingya documents. Further, Anne and James help us to connect to the archival and academic society.

And last but not least Datarella. We are in charge of the technical design, project management and development of the R-Archive.

Conclusion 

The R-Archive is a pilot for using Arweave decentralized storage technology for any kind of digital archive. We are confident to prove the benefits of using decentralized technology, like increased security, distributed custody and democratization, and a wider distribution of trust to the archival society. Stay tuned for more updates and insights on the R-Archive.
