What is German Blockchain Ecosystem?

GBE stands for German Blockchain Ecosystem. GBE is Deutsche Telekom’s blockchain-as-a-service platform (BaaS). It provides a full set of features and capabilities to anyone who wants to execute a blockchain or DLT project or participate in any blockchain or consortia.

We see the lack of secure blockchain infrastructure as one of the key hurdles for blockchain success in both public and enterprise areas. Naturally, we are addressing that need with a robust managed infrastructure offering for both public and permissioned DLTs. We are leveraging our security expertise and track record in running mission-critical infrastructure to provide secure Validation-as-a-Service to our clients. Our clients will be able to set up a managed validator based on variety of blockchain protocols such as Polkadot, Ethereum 2.0 or Cosmos Network.

GBE provides tooling and services for every stage of the DLT life cycle: Design, build, test, deploy and operate.


  • GBE provides capabilities, support, and pre-built templates for all levels of the blockchain solution stack

    Networking and infrastructure
    Security
    Distributed Ledger Technology (DLT) nodes
    Off-chain storage
    Payment processing
    Distributed applications

validator service realization

Allows rapid deployment of validator nodes for both new and established proof-of-stake solutions.

Shared record management solution

Can be used as the starting point for any DLT solution that intends for multiple parties to share a single version of the same data (e.g. medical records, land registry, etc).

 

Supply chain realization

Provides a working provenance and track-and-trace solution that can be tailored to a project’s individual needs.

Finally, GBE provides realizations: pre-built working solution templates across all these levels that can be used as delivery accelerators, making it much faster to get new blockchain solutions up and running.

Each of these realizations comes with a pre-built DLT ledger, off-chain storage, and a pro-forma dApp which knows how to access the ledger, ready for customization and deployment.


 

 

  • Five important things to understand about blockchain and DLT projects:

    There are lots of them. To date there have been over 80,000 blockchain projects around the world.

    They are fast. The typical blockchain POC or pilot lasts between 4-12 weeks. The average age of a blockchain project that has deployed into production is about 1.25 years.

    Most DLT project teams do not have skills do run own infrastructure. As blockchains start securing more real-world value and processes, the need for secure infrastructure is evident. Most lack experience and track record to run own blockchain infrastructure securely.

    Most of them don’t deploy into production. Of those 80K blockchain projects, over 92% of them either failed or completed without moving into a production solution.

    There are currently no EU-native BaaS offerings. Operating in the EU requires solutions that are fully compliant with all EU laws, regulations, and standards. Successful adoption requires a solution that not only meets these requirements, but also respects EU cultural norms.

With DLT projects being so fast, and with only a small percentage of them going into production, it is critical that solution development teams spend their time on delivering value rather than on setting up and tearing down DLT operating environments.

Supported protocols

Core Capabilities

INFRASTRUCTURE

DBO provides the ability to deploy and manage various types of nodes own OTC cloud platform, which is fully secure and EU-compliant. This is the default option, and the first node on any instantiated GBE blockchain will always be an OTC node.


As illustrated by recent service failures, a blockchain in which all nodes reside on a single cloud provider is not a true blockchain. Therefore, it is absolutely necessary for any production blockchain solution to support the creation of nodes that run on a number of different clouds; it is also extremely important for mission-critical infrastructure such as validator nodes in order to maximize uptime. GBE provides the capability to establish DLT nodes on most of the major cloud providers currently in operation.


Despite the increasing prevalence and advantageous cost case for cloud computing, there are a number of situations and use cases where it still makes sense to run a DLT node on provider-owned servers or data centers. GBE provides the capability for users to instantiate DLT nodes within their own infrastructure.


Our long track record in securely running mission-critical infrastructure for a large number of German industry players and state institutions allows us to guarantee security and efficiency for your blockchain infrastructure and your applications. The Open Telekom Cloud, Deutsche Telekom's public cloud offering, is the only cloud available in Germany to be awarded the "Trusted Cloud" certificate initiated by the German Federal Ministry of Economics and Energy - Data Center Insider.


In many countries and many use cases, there are strict data residency rules that insist on customer data never leaving defined international boundaries. GBE’s infrastructure capabilities allow the construction of DLT solutions that are capable of fully complying with such data residency requirements.


GBE Deployment Models

In this deployment model, GBE users have the ability to create and manage new, dedicated DLT ledgers, for use in creating completely new public or permissioned DLT solutions. To private ledgers are under the full control of their creator, and accessible only to whom the creator makes them visible. This capability automates the setup and configuration of any supported DLT protocol, and allows the ledger to be visible and manageable via the full set of GBE tools.


Many DLT projects are not about instantiating new ledgers, but implementing new solutions for existing ledgers; this is particularly true for some of the larger permissionless ledgers like the main Ethereum ledger. For these situations, GBE provides a Model Public Chain, an environment in which projects can develop and test their solutions prior to using the publicly visible ledgers or their testnets. GBE provides a Model Public Chain for each of its supported DLT protocols.


For projects that wish to use other DLT protocols, GBE provides the option to create a Protocol SanGBEx. The Protocol SanGBEx does not include the native substantiation, node creation, or monitoring tools provided for the natively supported DLT protocols, but it does provide a secure space in which projects can manually set up and configure nodes for any DLT protocol they wish.


GBE in the Software Delivery Life Cycle

The GBE Realizations include fully completed design artifacts that can be used as templates and as starting points to accelerate the delivery of projects built on GBE. Available artifacts include
Personae
User journeys
dApp wireframes
User stories
Data models
Project plans


GBE provides a full management dashboard for monitoring and configuration of all GBE services and capabilities. This dashboard is built over a fully functional set of supported API’s, so that GBE users have the option of integrating GBE capabilities within their own systems management dashboards, tools, scripts, and analytics.


GBE Value Added Services

To properly test the behaviour of both distribute ledgers and smart contracts under load, GBE provides a mechanism for simulating live solution traffic. Projects can define a Transaction Injector that accepts comma-delimited files in a specified format with input transactions for the solution being developed. Transaction injectors can be used for performance/stress testing, functional acceptance testing, and sales demos.


In the majority of enterprise blockchain use cases, a group of enterprises agree to share a single version of truth about a particular class of assets or services (e.g. insurance policies, shipping containers, land deeds, medical records, etc.) amongst a trading network of enterprises that do business with one another. Often, this trading network will require a known and accepted single source of truth for information; for instance, an application that tracked shipping containers would need a source of weather information that everybody agreed was the reference point for weather. Trusted authorities like this have come to be known an as Oracle (no relation to the software company of the same name). GBE provides tools that make it easy to set up and establish oracles for DLT solutions built by GBE users. These oracles will be accessible by all network users of the deployed solution, whether those users are on GBE or not.


GBE includes the capability to perform bulk data loads, both onto distributed ledgers and off-chain storage.


Since almost all DLT use cases involve multiple parties agreeing a single version of the truth, it is often desirable to let multiple parties validate transactions without divulging private or protected data. GBE includes a zero-knowledge proof module that allows for trusted validation (e.g. of identity, status, location, etc) without needing to share the underlying data.


Since a significant number of blockchain solutions have a functional requirement of being able to accept payments, GBE will include integrated support for a curated number of secure payment gateway providers.


In addition to the value-added services offered directly by T-Systems, GBE will include a solution marketplace that allows carefully selected third parties to offer their own extensions of GBE functionality.


GBE Delivery Accelerators

To ensure that DLT project teams spend their time adding value rather than wasting time on purely mechanical coding tasks GBE supplies working dApp templates that already include the necessary code to connect to distributed ledgers and off-chain storage hosted on DLT. Project teams can start with these templates and customize them to meet their specific design requirements.


Since the whole point of GBE is to allow project teams to get their solutions up and running as quickly as possible, T-Systems has invested in the creation of working blockchain prototypes that can serve as delivery accelerators, starting from a point where all of the basic functionality for a working blockchain solution has already been in place, so that your project team can focus exclusively on the parts of your solution that add value. We call these prototypes Realizaitions. The initial GBE Realizations focus on the two areas of blockchain solution development that are currently most prevalent:
Supply Chain Track and Trace:
Establishing the provenance of components in a supply chain is difficult, time-intensive, and critically important in many situations, and because of its inherently multi-party nature, supply chain provenance is particularly well-suited to blockchain solutions. To this end, GBE includes a Supply Chain Realization that allows individual project teams to start with a provenance solution that already works, so all they have to do is adapt it to their own particular data, UX, and business process requirements.
Shared Record Management:
Many blockchain use case domains, such as medical records, land registry, and identity, have a strong degree of functional similarity, in that they are all focused on multiple parties holding a single source of truth that is shared and kept synchronized between all members of a business network. The GBE Shared Record Management Realization provides all the functional basics for separate legal entities sharing a single version of a data record.
