EMC is an old coin released in December 2013, which is produced by POW and POS dual mining. EMC is a very low-key technical genre of digital currency. Although EMC did not have much popularity in China in the early stage, its research and development progress has made a lot of progress. So far, EMC has developed centralized domain names and DNS System, distributed login solution without password authentication, decentralized solution for Shell management, decentralized pay-per-click advertising system, proof of ownership stored in the blockchain, trusted timestamp service stored in the blockchain, distribution There are many very practical blockchain applications such as a network seed file tracker and a micropayment library for streaming media. Although few domestic users know about EMC, EMC has continued to transform and optimize for more than two years, and its progress on the technical side has been far higher than that of most digital currencies. Currently, EMC has been supported by Microsoft Azure, and the EMC team is also seeking to cooperate with For cooperation with many well-known companies such as IBM and DNSPOD, you can pay attention to the official communication community for details.

1. Project introduction

Emercoin is an emerging leader in the field of distributed secure blockchain business services. As more companies start using Emercoin technology, there is a core Emercoin team that maintains and develops services on the public Emercoin blockchain. Emercoin Blockchain uses Emercoin (EMC) to provide various services. Already delivering many of the most innovative real-world solutions, the Emercoin blockchain is the top public blockchain of choice for secure, decentralized business operations.

Project Features

Flexibility:
Emercoin's "Name-Value Store" (NVS) concept is simple yet powerful, allowing users to store arbitrary data in the blockchain. A series of distributed services have been realized through it, such as decentralized DNS and free VoIP services.

Reliability:
Although Emercoin supports traditional PoW mining and joint mining with Bitcoin, its main mechanism is still the proof-of-stake mining model. In this way, an "arms race" in mining capacity is eliminated, and simply holding Emercoin can guarantee a 6% annual rate of return.

Security:
Emercoin will never sacrifice security for the pursuit of flexibility. Unlike so-called “smart” contracts that have caused millions of dollars in fraud and security breaches in the past, Emercoin’s NVS logic is not Turing-complete and cannot be used to write malicious code.

Application scenario

EmerDNS:
EmerDNS is a decentralized domain name system that supports various DNS records. EmerDNS runs under the service acronym "dns" in Emercoin NVS. Powered by Emercoin's distributed secure blockchain, domain name records are completely decentralized and cannot be censored. No organization can be amended, revoked or closed down. Only the owner of the record (i.e. the person who has the private key to the associated payment address) can modify it or transfer it to others. These operations are performed via Emercoin NVS in the Emercoin Wallet GUI, or via the name_new or name_update commands in the Emercoin API.

EmerSSH:
EmerSSH is a system that uses the Emercoin blockchain to manage public key infrastructure (PKI) and access control lists (ACL).

EmerSSH can connect to OpenSSH, providing a convenient, secure and flexible way to log in to multiple servers via SSH. In this case, OpenSSH is configured to reference the emcssh tool, which will query the Emercoin blockchain and retrieve SSH credentials during the authentication process. Through EmerSSH, users can use the GUI or command line to submit and modify records in the Emercoin blockchain to manage their own public keys. Similarly, administrators can manage service user groups and individual users that contain references to other groups, thereby creating recursive authentication trees.

EmerSSL:
EmerSSL is a password-free website authentication system that uses the Emercoin blockchain as a decentralized trusted store of client-side SSL certificate hash checksums. Certificates can be generated by users on their own computers, eliminating the need for a centralized certificate authority, and can be quickly replaced as needed. This allows the system to efficiently perform scheduled updates or quickly recall compromised certificates.

EmerSSL makes the system completely decentralized. In other words, no entity is in control of authentication, which is very different from systems like Kerberos, OpenID, TeddyID, etc. As a result, EmerSSL will not suffer system-wide service interruptions regardless of technical failures or malicious attacks on servers. Also, there will be no worldwide shutdown of a user account due to a sudden decision by an institution.

EmerDPO:
EmerDPO is a decentralized solution for digitally verifying ownership and authenticity of physical and digital goods and services via the Emercoin blockchain. EmerDPO operates under the service acronym "dpo" in Emercoin NVS.

2. Comments

Rising Coin EMC was released in December 2013. It is generated by POW and POS dual mining. The total amount is balanced by the annual increase of POS by 6% and application consumption. As of the end of 2018, EMC has developed a decentralized domain name and DNS system, a distributed password-free authentication login solution, a decentralized solution for Shell management, a decentralized pay-per-click advertising system, proof of ownership stored in the blockchain, There are many very practical blockchain applications such as trusted timestamp services stored in the blockchain, distributed network seed file trackers, and micro-payment libraries for streaming media.
