Blockchain for business: Ethereum vs. R3 Corda vs. Hyper Ledger Fabric vs. Quasar (Stellar)

the The Frankfurt School, has published a "decision aid" for entrepreneurs, who want to go the way of the decentralisation. The authors of the paper compare common Distributed Ledger technologies (DLT) for the company. It: Ethereum, R3 Corda, Hyper Ledger Fabric and Quasar (for Stellar).

Not everywhere, where "Blockchain", is a public, decentralized transaction register. When it comes to the use of the Blockchain technology in business, often a marketing effective corruption of the term. You can't stress often enough that it is in the Blockchain technology, a special molding of a Distributed Ledger technology. On this circumstance, the authors of the Frankfurt School, "a decision aid for the use of Blockchain-technologies in business: Four Frameworks compared" at the beginning of your Papers.

– the title already indicates – compare Philipp Sandner and Daniel Höfelmann of the Frankfurt School, and Business solutions to a DLT-based. As evaluation criteria, the analysts define user-friendliness, efficiency, and Performance, based on cost efficiency, Release-ability and timeliness, security, and administration.

Installation and user-friendliness

points Here, both Ethereum as well as R3 Corda and Hyper Ledger Fabric. While in the case of Ethereum, especially the detailed documentation on GitHub to praise is mentioned, Hyper Fabric Ledger and Corda in the category of modularity points. So Hyper Ledger allows its modules (of which the Fabric itself creates a) a more targeted implementation, as this is, for example, in the case of Ethereum. Since Quasar is no public documentation exists, truncates this Underdog-DLT in this category.

(cost-)efficiency and Performance

Here are all four of the studied DLT roughly on a par. However, Ethereum is lagging behind in the field of the TRANS-action volumes in the competition – at least in its current Proof-of-Work-loft. Nevertheless, Hyper Ledger Fabric, R3 Corda and Quasar is available here no top reviews. The researchers justify their decision like this:

Quasar/Stellar, Corda, and Fabric call to higher values, however, have been documented in Corda and Fabric on the basis of the Research, this is only in very favorable selected and only from the respective manufacturers/consortia Tests. A testing and/or confirmation of the high volume of transactions by a third party, was for all the three systems are not accessible. In this respect, can be Quasar/certified Stellar, Corda, and Fabric, no positive values.

at Least were able to convince all four of DLT in the field of transaction fees. In the case of Ethereum and Hyper Ledger, the analysts of lower maintenance costs, since these networks over a larger Pool of developers than the competition:

In both cases, and can be selected from a large amount of external developers, what the pricing is influenced to be more positive. At Corda, and Quasar/Stellar, however, at least unclear, as the market matured and external developers with relevant experience.

Release-ability, and timeliness

In this category can Shine Ethereum. Particularly the large (developer-)Community is speaking here, for the head of birth Vitalik Buterins. However, the authors of the Papers Hyper Ledger Fabric, R3 Corda and Quasar/Stellar a better upgrade ability will attest.

security

here, Too, can Ethereum, as the only representative of a truly decentralised, public DLT points. Through the open source of the code, this is subject to the constant Review of a growing developer community. Here are the more completed systems, Hyper Ledger Fabric, R3 Corda and Quasar/Stellar can't keep up, by definition. However, the authors of the analysis point to the fact that there are on all of the platforms are still unresolved issues. This concerns in particular compliance with the data protection regulation (DSGVO). Especially in the area of data protection, the authors see mainly the developers of the respective (d)of the Apps in the duty.

administration

the situation is Different with regard to the management of each of the DLT. As regards interoperability, testability, and Logging, on Ethereum in the competition. What does not mean, however, that these Features were not in Ethereum integrate:

This is mainly due to the fact that the three systems are designed per se for Business infrastructures and, therefore, its architecture is a higher level of interoperability and Features, such as testability and Logging. Nevertheless, the Blockchain, the adaptability of a permissioned these Features in Ethereum. Solely the initial cost is higher and this can be substantially higher.

conclusion

The conclusion of the authors is a balanced approach. As Sandner and Höfelmann point them to security vulnerabilities that have arisen in the case of Ethereum due to faulty Smart Contracts and partial (DAO-Hack!) horrendous havoc. Although these weaknesses are not in the Ethereum-a Blockchain – founded, this fell even as-yet still no Hack for the victims. However, the DAO-Hack provides just an example of what can cause a weak-programmed Smart Contract for damages. In spite of everything, the two authors Ethereum to confess to the highest level of security:

a Total of Ethereum but it seems to short and medium term, the highest investment security: Ethereum is Open Source, has a large Community and at the same time a high level of global distribution. The investment in significant business processes on a self-or jointly with other actors controlled Ethereum-a Blockchain can be used with the highest probability for a long time.

However, in the case of Ethereum lower volume of data for some companies could be a criterion for exclusion.

So long for Ethereum is still in the Proof-of-Work algorithm to use, will change little. Ethereum wants to answer the scalability question with the change to Proof of Stake (PoS). This is, as yet, still on waitingn, I understand that the code base is for the PoS-algorithm, however, is nearing completion.

the other three DLT – Hyper Ledger Fabric, R3 Corda and Quasar/Stellar, it is the authors difficult, a clear "winner". For Hyper Ledger Fabric speak, therefore, above all, the commitment and the experience of the Linux Foundation as a patron of the project.

the Blockchain?

Last Sandner and Höfelmann raise the question of the meaningfulness of a private, "permissioned" DLT.

The great challenge of all the pure permissoned DLT solutions is the possibly loss of all the significant attributes, which are particularly attributed to the public block chains: the immutability of history, high level of security against many attack vectors, such as Sybil and Denial-of-Services attacks (DoS), as well as the network's inherent challenges, such as "Practical Bytzantine Fault Tolerance".

If a DLT solution and the unique outgoing characteristics of a public, "permissionless" Blockchain, you have to ask yourself as an entrepreneur, whether a changeover of business on DLT surrender any sense at all.

lost the essential attributes, the question is, why don't well-designed and technologically fully tested solutions should be used: This could be a centrally controlled platforms with rollers thought/rights principles, at probably a lower cost and higher availability of developers and System architects, and overall, a greater understanding in the entire organization.

Therefore, the concrete formulation of the desired target system for the decision-making process, as well as Watching the further development of Use Cases for private DLT and Ethereum is essential.
