One of the big advantages of the blockchain technology is the anonymous transaction and the anonymous identity of transactors. The blockchain especially the mainstream leaders both bitcoin and ethereum try as much as possible to make transactions as transparent as possible by have their transactions log in a public log that can be accessed by anyone anywhere in the world. Series of transactions can be looked into and individual is to backtrack transactions and look into anyone's balance. This is an exciting feature and it give users rest of mind because it is transparent enough.
In this world today where privacy is being breached every now and then, and big companies loose billion of dollars every year based on their privacy security breach. This is getting to the blockchain technology too. The blockchain is being used in many sector and blockchain is now being applied in different businesses like health, casinos and online betting. This public log or ledger on the blockchain can easily allow people to trace business transaction from a particular person and their real identity can be matched with their wallet transactions, then people can know who is who on the blockchain. So where is the anonymity and the privacy?.
Many cryptocurrency have walked on this path of creating a more secure and private blockchain for transactions that can only be know to the sender and receiver. Cryptocurrency like :
MONERO
Zcash
Dash
Etc.
Have tried their best in improving privacy on the blockchain. Many of this cryptocurrency while trying to create something new and different from the native way of the blockchain misses out on key features of the blockchain like the smart contract and Dapps.
SERO (Super Zero) is the world's first blockchain system that truly realizes the complete privacy
protection of blockchains through non-interactive zero-knowledge proof. Compared to the existing
blockchain privacy protection technologies, SERO not only can realize the privacy protection of
account and transaction information but also support Turing complete smart contracts. In addition,
developers can also create their own encrypted cryptocurrencies supporting smart contracts based on
SERO-Chain.
