Sobrang palalim na po ng palalim ang usapan dito sa cryptocurrency. And I know na marami pa din ang mga newbies dito na naguguluhan kung ano ba ang bitcoin at kung saan ba to nggaling.
First, let us tackle the history of bitcoin base po sa pagkakaaintindi at pagkakabasa ko para lahat po tayo ay merong idea at hindi agad agad nagjujump in sa kung paaan ba ang magparank up at kung paano ang kitaan.
As I am exploring bitcoin, nabasa ko po na hindi pala siya ang first ever digital currency.

Napagalaman na sina Wei Dai and Adam Back ang dalawang tao na kinontak ni Satoshi Nakamoto sa pagdedevelop ng Bitcoin in the year 2008 and yong B-money paper ay nasa reference sa Bitcoin whitepaper.
Since, ang bitcoin ay similar sa Bitgold kaya nagkaroon ng speculation na si Szabo ang totoong Satoshi ngunit ito ay kaniyang itinanggi.

Matagal na talaga tech ng btc kaso wala talaga nakaka solve ng real problen ng digital currencies noon - solving yung double spending at Byzantine-Fault Tolerance(BFT) or Byzantene Consesnsus Alhorithm. Na syang an solve nung na develop ang Blockchain tech using proof-of-work protocol. Bitcoin is the first program or application sa blockchain platform.
After that, marami na na develop na BFT platforms na sinasabing mas convinient pa raw sa blockchain.
