we have obtained a proprietary system patent that utilizes blockchain technology (NFT: non-fungible token) related to certificity proof.

this ensures fairness and neutrality, and its strength is that it is differentiated from other companies' technologies as a “decentralized type” that cannot be illegal and tamperedrather than a “centralized type”.

each company is engaged in business related to certificity verification, but they are mainly “centralized type”.

with the “centralized type”, in-house employees and outsourced system development companies can arbitrarily illegal and tamper.

on the other hand, the “decentralized type” “cycaltrust certification system ®” is almost impossible for our employees, outsourced system development companies, and even our company to be illegal and tamper.

because each three features of “blockchain” and “NFT(non-fungible token)” enable certificity proof as “only one”.

in other words,illegal and tamper is almost impossible for any of our employees, outsourced system developers, and even us.

the reason why people cannot help but using “centralized type” systems is just no platform to secure certificity proof by “NFT (non-fungible token)” as “decentralized type” ever.

therefore, there has never been a system that guarantees certificity proof, which is almost impossible for illegal and tamper by a third party.

however, since the “cycaltrust certification system ®” is a “decentralized type”system, illegal and tamper is almost impossible for any of our employees, outsourced system development companies, and even our company.

with the “centralized type”, in-house employees and outsourced system development companies can arbitrarily perform illegal and tamper, so it is not possible to guarantee highly accurate and reliable certificity proof.

on the other hand, if we utilize “NFT (non-fungible token)” as a “decentralized type”, it makes buyer (consumer) enjoy shopping at ease due to no possibility of illegal and tamper.

sellers (producers), buyers (consumers), and the society are looking for it.

（1） sellers (producerss) ① sales increase, ② intellectual property protection, ③ competitive strategy, ④ exclusion of illegal and tamper

（2） buyers (consumers) ➀ safe shopping, ➁ product safety assurance

（3） society ➀ transparency of corporate “CSR”, ➁ eradication of organized crime

it is true to manage “centralized type” easily, but it can be illegal and tamper by in-house employees and outsourced system development companies instead.

after all, it takes rather high costs to monitor them.

although it costs money to use the “cycaltrust certification system ®”, it is possible to recover the exploited sales (“20%” of the sales are exploited※3）.

as a result, sales turn positive even after deducting usage costs.

the best way is getting embedded in the manufacturer's (producer's) production line.

however, there are other options like attaching various shapes of “cycaltrust certification chip ®” (peeling seal type tip, etc.) to products later in the case which cannot do this like secondary distribution.

if you develop a new system at the request of your or another company, you will need significant cost, time, and other resources such as blockchain (NFT：non-fungible token) know-how.

at the same time, the “cycaltrust certification system ®” has been widely patented for certificity proof, which may result in patent infringement.

it is virtually impossible to create defects in the system by three features of blockchain and NFT (non-fungible token) (please check Q.3).

in addition, a high cost is required to manufacture “fake plagiarism products” which can surpass these features, which is inevitably a deterrent.

it is eligible for subsidies since it is a “system construction cost (outsourcing cost)”.

example) “business restructuring subsidy”, “manufacturing subsidy・manufacturing / commercial / service productivity improvement promotion subsidy”, “IT introduction subsidy”, etc.

certainly it is true that “single-sig certification” can reduce costs, but it has defects to possible to certificate with only “one secret key”.

therefore, there are the following three disadvantages.

• ① easy to make “fake plagiarism products”
• ② low security
• ③ it does not serve as a deterrent to theft

yes, it cannot realise “truth certification proof” by “single-sig certification”

this is because with “single-sig certification”, the same product can be easily duplicated as long as “only one private key” can be copied, and it does not meet the requirements for “certificity proof”.

in addition, since privacy (personal information) is easily leaked with “single-sig certification”,“single-sig certification” is inappropriate from the viewpoint of personal information protection.
