Number Portability Databases (NPDB) play a pivotal role in modern telecommunications by facilitating the seamless transfer of phone numbers between service providers. However, traditional NPDB systems face significant challenges, including centralization, high costs, and security vulnerabilities. This paper proposes novel approach leveraging blockchain technology through ENUMER system. ENUMER, designed initially to enhance ENUM operations, demonstrates unique suitability for tasks due its...

This paper presents a method for mitigating unwanted communications such as spam, robocalls, and DoS attacks, proposing proactive approach based on creating financial accountability message originators through electronic postage stamps utilizing blockchain technology. The concept involves each email or being accompanied by an unpublished transaction that destroys small amount of the originator's coins, termed "electronic stamp." If is deemed unwanted, recipient can publish stamp blockchain,...

Randpay is a technology developed in Emercoin for blockchain micropayments that can be more effective some scenarios than the Lightning Network as we show paper. The protocol based on concept of Ronald L. Rivest and published paper "Electronic Lottery Tickets Micropayments" (1997). "lottery ticket" was designed centralized systems where trusted third party required to provide payments, also lottery facilitator. existing cannot accommodate peer-to-peer "lottery" at least without need create...
