EdenChain Transaction Processor

by Brian Park

Edenchain can develop block-chain applications using APIs. It is an effective development method for blockchain application developers as it is relatively easy and quick to develop, and the available manpower can be secured easily.

From a developer perspective, developing an application using the Edenchain API can be described as developing a custom TP (Transaction Processor). TP stands for a software module that literally has business logic to process a specific task, such as checking the balance of an account or implementing functions associated with blockchain, such as remittance.

It is a principle that TP implements one function. Therefore, if many blockchain functions are required, it is necessary to develop TPs corresponding to the number of functions. Edenchain is, therefore, a blockchain application that is a collection of multiple TPs. Therefore, developing an application based on Edenchain can be explained by the development of a TP using the Edenchain API, and the consolidation of the TP is a software module implemented using the Edenchain API.

TP Handling

Except for the fact that the Edenchain API is applied, TPs are no different from common software modules and no special explanation is needed. However, understanding how Edenchain processes TPs is required to create optimized TPs.

On the Edenchain platform, once the TP is executed, it blocks the related tasks until the TP is completed and secures data consistency. Blocking is especially needed to handle write-related tasks rather than read-related tasks. Because blocking is maintained until the start and end of a TP, TP should be developed to handle the process in as short a time as possible.

Especially, in the case of a TP that changes state, other work should not be performed concurrently. Therefore, the code should be optimized so that it can be processed in the shortest possible time. TP can be implemented either as a sync method or async method or as both methods. However, it can not be expected to improve much unless the TP is developed in accordance with Edenchain’s processing method. This is if methods are grouped together the Performance Bottleneck eventually affects Edenchain. Therefore, we can expect better performance by breaking tasks into smaller units and dividing them into multiple TPs rather than processing them all at once by putting all the functions in a single TP.

TP Deployment

The developed TP can be deployed in three major ways as needed.

TP interacts directly with the Edenchain Platform and has many interactions inherent to its design. Therefore, the network speed between the TP and the Edenchain platform affects the overall performance of the application.
For faster and safer applications, deploying TPs in the Edenchain cloud computing zone would produce the best results. Because it is located in the same cloud zone, the network latency is low and TP can operate securely in the internal computing zone.

However, there may be cases where it is not possible to deploy TPs in the cloud due to policies or data ownership of application developers. In this case, the TP can be operated using the existing computing zone. In this case, however, it is much slower and more likely to cause security problems.
The Hybrid can be used in combination with some of the advantages of both schemes, some in the Dedicated Namespace Zone and some in the Legacy Zone.

Comments

The TP processing module currently running on Testnet has room for improvement. The ability to process the TPs separately for each Namespace is one of the perspectives that can be most likely improved. When an external TP request comes in, Edenchain does not process it by Namespace, but it is processed by a task management system. Because it is limited in performance and scalability, we are planning to improve this part by providing each namespace with TP processing module and enabling it to be executed independently.
