Zcoin has rebranded to Firo,
Zcoin:
Creation
In the late 2014, Poramin Insom, a student in Masters in Security Informatics from Johns Hopkins University wrote a paper on implementing the zerocoin protocol into a cryptocurrency with Matthew Green as faculty member.[13][5] The project to create a standalone cryptocurrency implementing the Zerocoin protocol was named "Moneta".
On 28 September 2016, Zcoin, the first cryptocurrency to implement the zerocoin protocol, was launched by Poramin Insom and team.[5][16] Roger Ver was the initial investor.
Firo:
In October 2020, Zcoin announced rebranding to new name called "Firo" which signifies a unique way of burn (destroy) and redeem coins. Firo suffered 51% attack in January 2021. Firo has since implemented ChainLocks on Firo's blockchain which should make it nearly completely resistant to 51% attacks. In June 2021, Firo was added to NOBI trading platform based in Indonesia.[44] Firo implemented Receiver Address Privacy (RAP) in June 2021. In August 2021, Firo announced the Lelantus Spark protocol. This protocol offers additional privacy features, including generating new one-time addresses for receiving payments, efficient multisignature operations, and the availability of view keys for authorised third parties to view a transaction.
Zero-knowledge proofs
Firo initially implemented the Zerocoin protocol. Unlike bitcoin, money does not travel from one block to another. Instead, it is traded as Zerocoin and redeem for a new coin without any history of transaction. However, the disadvantage of this system is that the transaction amount cannot be hidden. There had been little research interest into Zerocoin protocol because of its similarity to Zerocash protocol. Therefore, Firo implemented a new transaction system called Sigma protocol on 30 July 2019 that replaced the previous Zerocoin protocol. Thus, the trusted setup was removed and proof size was reduced from 25kB to 1.5kB. Besides, Firo also developed the Lelantus protocol by improving upon the Sigma protocol.
