The asymmetric cryptography was produced for military use in the 1970s, and it was promoted by cypherpunk in the 1980s to solve network information security and protect personal privacy. It is mainly used for network communication and the construction of token system, that is, cryptocurrency.
Free consensus is a cryptographic consensus system based on the evolution of the Satoshi Nakamoto framework. It is an evolution from a peer-to-peer electronic cash system to a crypto economy infrastructure, extending from decentralized free cash to decentralized identity, relationship, reputation, agreement, storage, etc., which foundation for the crypto economy.
The essence of the distributed consensus mechanism is a simple democratic mechanism. It is acting in accordance with the rules and judgments approved by the majority. The emergence of peer-to-peer network technologies such as NGK and BitTorrent provide technical conditions for establishing a distributed consensus system on a global scale through the network.
The NGK cryptographic consensus system is a technical and economic system constructed by asymmetric cryptographic and a distributed consensus mechanism. It mainly solves the problems of information security and monopoly in the information economy.
From 2007 to 2009, Satoshi Nakamoto discovered that the root cause of the failure of early cryptocurrencies was the “centralization” of the system. To this end, he used the distributed consensus mechanism for cryptocurrency and established the first decentralized cryptocurrency, namely Bitcoin.
The Bitcoin system established by Satoshi Nakamoto using asymmetric cryptography and a distributed consensus mechanism is both a technical system and an important economic system. It allows people who have never known each other to maintain a vital economic system consciously, which is the world currency.
NGK refers to this system framework as “cryptographic consensus”, that is integrated by “asymmetric cryptography + distributed consensus”. It protects information security with asymmetric cryptography and eliminates central monopoly with distributed consensus. Therefore, it can be used for the construction of information economy infrastructure. The NGK blockchain is only one of the data structures used in the distributed consensus mechanism, and it cannot fully reflect the nature and significance of cryptographic consensus.
Sharding is the future of blockchain scalability. It is the key in promoting the blockchain ecosystem to support thousands of transactions per second and allowing most of the world to use the platform frequently at an affordable cost. However, sharding is also one of the easily misunderstood concepts in the blockchain ecosystem. Sharding refers to a set of very specific ideas with very specific properties, but it is often confused with technologies that have much different and weaker security properties.
The easiest way to understand sharding is through random sampling. Compared with the sharding form established in the NGK ecosystem, sharding through random sampling has weaker trust attributes, but it also uses simpler technology.
