With the exception of pseudonymous developer Harry Ullman, the identities of the Bytecoin (BCN) developers are not known.<ref>{{Cite news|url=https://www.ccn.com/interview-harry-ullman-bytecoin/|title=Will Bytecoin Eventually be the Preferred Currency for DarkNet? - An Interview with Harry Ullman of Bytecoin|date=2015-06-17|work=CCN|access-date=2018-11-18|language=en-US}}</ref> Bytecoin was publicly announced on March 2014, however the CryptoNote v1 whitepaper dates back to December 2012 and the original site shows the first block being mined on July 4th, 2012<ref>https://cryptonote.org/whitepaper_v1.pdf</ref><ref>{{Cite web|url=https://bytecoin.org/old/|title=Bytecoin|website=bytecoin.org|access-date=2018-11-18}}</ref>.

In September 2018, Bytecoin announced a partnership with Chinese exchange Gate.io.<ref>{{Cite news|url=https://cointelegraph.com/press-releases/privacy-oriented-cryptocurrency-features-on-chinese-exchange-gateio|title=Privacy-oriented Cryptocurrency Features On Chinese Exchange Gate.io|last=Cointelegraph|date=2018-09-28|work=Cointelegraph|access-date=2018-11-18|language=en}}</ref> One month later on October 2018, Binance announced its delisting due to falling below their quality standard.<ref>{{Cite web|url=https://support.binance.com/hc/en-us/articles/360017720731-Binance-Will-Delist-BCN-CHAT-ICN-TRIG|title=Binance Will Delist BCN, CHAT, ICN, TRIG|website=Binance|language=en-US|access-date=2018-11-18}}</ref> Just one month after in November that year, Poloniex announced due to network instability, Bytecoin would require 2,000 block confirmations before users would be credited with the coins.<ref>{{Cite news|url=https://www.ccn.com/poloniex-requires-2000-confirmations-for-bytecoin-transactions/|title=Poloniex Requires 2,000 Confirmations for Bytecoin Transactions|date=2018-11-12|work=CCN|access-date=2018-11-18|language=en-US}}</ref>

== Features ==
{{Unreferenced section|date=November 2018}}
Bytecoin is an open source software. Cryptocurrency uses the principle of Proof-of-work ("Proof of work performance").

The algorithm for mining in Bytecoin differs in that it actively uses the [[AES instruction set|AES command system for x86 microprocessors]] and a large amount of memory, which makes mining on the [[GPU]] less efficient than for Bitcoin.{{Citation needed|date=November 2018}}

Since the launch, several improvements have been made, including multi-valued transactions and several security updates. In 2013, the original implementation of [[CryptoNote]] [[Java (programming language)|Java]] was rewritten using [[C++]].<sup>[''[[Wikipedia:Citation needed|citation needed]]'']</sup> As of 2015, Bytecoin has been forked more than 25 times.<sup>[''[[Wikipedia:Citation needed|citation needed]]'']</sup> Bytecoin [[blockchain]] contains additional information not directly related to remittances: several blocks include the geographical coordinates of universities, educational institutions among other buildings.<sup>[''[[Wikipedia:Citation needed|citation needed]]'']</sup>

It uses the unique [[CryptoNight]] algorithm. The essence of the algorithm is in the ring signature, which provides anonymity. The cryptographic basis for the protocol was created by [[Ron Rivest]], [[Adi Shamir]] and [[Yael Taumann]] in 2001, and finalized by E. Fujisaki and K. Suzuki in 2007. The EdDSA scheme proposed by the American mathematician [[Daniel Bernstein]] is used as the signature algorithm. Additional transaction [[obfuscation]] was added to this basis.

Due to [[CryptoNote]] and the [[obfuscation]] added to the protocol, passive mixing is provided: all transactions in the system are anonymous, and all participants in the system can use [[Plausible deniability|plausible deniability]] in the event of a capture.
