1.1.1. What is mijin Catapult(v.2)?

mijin Catapult(v.2) allows you to build a viable private blockchain with minimal resources.

As a private blockchain product that replaces existing databases, it utilizes multiple cryptographic signature functions and is used in many projects.
Without compromising the atomicity of transactions, mijin’s account engine operates as a fully distributed, zero-downtime network that assumes high security, minimizing the need for application development and maintenance.
Tokenize any data or asset with a simple definition and process all transactions as secure, one-time smart contracts, with speeds of thousands of transactions per second.

mijin Catapult(v.2) will offer new features such as aggregate transactions (1,000 transactions simultaneously with atomicity) and Fully distributed atomic swap technology with guaranteed atomicity through Multilayer Signature (3 levels of multisig authentication).
All of these advanced features can now be implemented with a minimum of knowledge and man-hours, thanks to the feedback we have received from our customers over more than five years of practical cases in V1.
The combination of this experience and technology with NEM, a public blockchain that has been in operation for many years, is now being offered for the first time as a commercial blockchain product from Japan on the AWS Marketplace.
The following site also provides a detailed explanation of mijin Catapult(v.2).
