When the respective leaders of South and North Korea shook hands on April 27, the world watched a new chapter of history being written. The declaration signed by the two sides brings to an end several decades of hostility between the neighbours, in what has become one of the world’s most volatile regions.
The meeting saw adversaries Kim Jong-un of North Korea and the South’s President Moon Jae-in agree to an end to the Korean war, which the two had technically been fighting for decades. Amongst other things, the declaration included the pledge that ‘there will be no more war on the Korean peninsula’.
Now, the historic declaration has been recorded permanently on the ethereum blockchain, courtesy of 27-year old South Korean developer Ryu Gi-hyeok. He recorded the Panmunjom Declaration in English and Korean, stored in two separate transactions on the ethereum blockchain.
Remarking on his decision to encode the declaration, Ryu Gi-hyeok said he felt it was a fitting market for the historic event.
“I just thought it took too long for the South and the North to give way to each other … After finding out what I could contribute to this historic achievement as a developer, I found the Panmunjom Declaration on the Blue House homepage and recorded it on ethereum.”
Following the #metoo campaign in China, which bypassed online censorship to share information over the ethereum blockchain, Ryu said he now intends to work on a project for recording and storing historic records on a blockchain.
The project, he suggested, would allow for records to be stored immutability within the blockchain on a permanent basis.
An open letter regarding abuse at Peking University was initially suppressed by state censors in China, driving activists offline in search of an alternative means of communication. The letter was then anonymously encoded and uploaded to the ethereum blockchain, which attracted a wave of support from others across universities in China.
The developments show how blockchain, the technology underpinning cryptocurrencies like bitcoin, can also be used to store data.
It comes shortly after online broker TD Ameritrade became one of the first companies to permanently write an advert into the blockchain, using invalid transactions to create and record the graphic.
