Cryptocurrency development preconditions

Scientific papers analysis shows us that the digital currency technology logically came to the advent of cryptocurrencies with ring signature and memory-bound function PoW implementation in 2012. There is a timeline for you to see it yourself: — 1983 – Blind signatures were invented by David Chaum (learn more) — 1997 – HashCash (proof of work system) was invented by Adam Back (learn more) — 2001 – Ring signatures were invented by Ron Rivest, Adi Shamir, and Yael Tauman (learn more) — 2003 – Mart Abadi, Michael Burrows, and Ted Wobber presented “Moderately hard, memory-bound functions” (learn more) — 2004 – Patrick P. Tsang and Victor K. Wei presented their paper “Short linkable ring signatures for e-voting and e-cash” (learn more) — 2005 – Matthew Franklin and Haibin Zhang with “Unique Group Signatures” study (learn more) — 2005 – Exponential memory-bound functions for proof of work protocols by Fabien Coelho (learn more) — 2006 – “Traceable Ring Signature” by Fujisaki and Suzuki (learn more) — 2008 – Bitcoin whitepaper by Satoshi Nakamoto (learn more) — 2009 – Stronger key derivation via sequential memory-hard functions by Colin Percival (learn more) — 2009 – First Bitcoin block was generated — 2010 -2012 Bitcoin Anonymity Problem Discussions (learn more) — 2011 – An Analysis of Anonymity in the Bitcoin System, Fergal Reid and Martin Harrigwere (learn more) — 05/15/2012 – Dorit Ron and Adi Shamir made Quantitative Analysis of the Full Bitcoin Transaction Graph (learn more) — 06/08/2012 – Bytecoin Wiki started (learn more) — 06/30/2012 – Bytecoin launch announcement (first news) — 07/04/2012 – First BCN block was generated — 08/06/2012 – Destination Address Anonymization in Bitcoin (one-time addresses in BCN) (first news) — 10/19/2012 – Evaluating User Privacy in Bitcoin by Elli Androulaki, Ghassan O. Karame et al. (learn more) — 12/12/2012 – CryptoNote whitepaper v 1.0 (learn more, TOR only) — 12/13/2012 – Analysis of hashrate-based double-spending, Meni Rosenfeld (learn more) — 10/17/2013 – CryptoNote whitepaper v 2.0 (learn more) Soon after Bitcoin’s release the community started to raise concerns about its anonymity with multiple solutions and propositions. High concentration of theoretical papers on these topics in 2009-2011 most probably spurred the brightest minds to make attempts of practical e-cash with ring signatures realization. Therefore, BCN couldn’t but appear in 2012. Based on Reddit’s BCN Community investigations
