On April 27 when the leaders of South and North Korea met and signed a peace treaty, one developer permanently recorded the historic event between the two nation on the Ethereum blockchain.
According to a report from CoinDesk Korea, Ryu Gi-hyeok, a 27-year-old South Korean game developer, coded two ETH transactions with the Panmunjom Declaration in both Korean and English, which includes the line “there will be no more war on the Korean peninsula,” and recorded both versions on Ethereum’s blockchain.
The event was widely publicized all over the world, having South Korean president Moon Jae-in and North Korean leader Kim Jong-un shake hands and signing the peace agreement to put an end to the Korean War
The unchallengeable and public nature of Ethereum’s blockchain means that the texts can be accesses by anyone, at any time, without the possibility of them being altered or deleted.
The South Korean developer said in a CoinDesk interview:
“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.”
Ryu stated that he was also planning on launching a website service that will “keep all historic records permanent and immutable” on a blockchain.
But this is not the first time blockchain has been used for dodging possible censorship. Student activists of the #metoo moment in China, used the Ethereum blockchain to record messages as a way to bypass internet censorship and share information.
The case involved an open letter written by a senior student from the prestigious Peking University about a past case of alleged rape which initially was removed from online platforms in China. However, the letter was converted to code and recorded on the Ethereum blockchain.
Aside from its many practical uses, the proprieties of Ethereum’s blockchain are now being used to fight against possible government censorship.
