John Lennon imagined that there is no heaven, no hell, nothing to kill or die for, no need for greed or hunger.

Satoshi Nakamoto proposed a system for electronic transactions without relying on trust.

Blockchain is a chain of ledgers distributed over a network that is robust in its unstructured simplicity, that is computationally impractical for an attacker to change, that no one can control but everyone can view, and that can connect an individual with another individual without giving up trust to a third party or a central authority.


that every single person on earth will have an ID and get access to education, health and other social services;

that 2.5 billion unbanked people will be included in the global financial system;

that foreign workers will not lose $50 billion collectively per year when sending money to their home across the county border;

that people will know about the life story of a product when they buy it; people who created the product, the places that were involved,  the material used etc.;

that people will live without fear that their land might be appropriated by someone who comes to door with a gun in their hands;

that artists will gain autonomy over their copyrighted material and build direct relationships with fans;

that patients will control over their personal medical records;

that foreign aid will reach its intended beneficiaries without losing 30% of its entirety;

Now we, individuals working for various UN organizations, have voluntarily gathered as one to make the world as one.

I hope someday you’ll join us, and the world will be as one. (yoshi3346)

Imagine there’s no heaven
It’s easy if you try
No hell below us
Above us only sky
Imagine all the people
Living for today…

Imagine there’s no countries
It isn’t hard to do
Nothing to kill or die for
And no religion, too
Imagine all the people
Living life in peace… You…

You may say I’m a dreamer
But I’m not the only one
I hope someday you’ll join us
And the world will be as one

Imagine no possessions
I wonder if you can
No need for greed or hunger
A brotherhood of man
Imagine all the people
Sharing all the world… You…

You may say I’m a dreamer
But I’m not the only one
I hope someday you’ll join us
And the world will live as one

Bitcoin: A Peer-to-Peer Electronic Cash System

“Commerce on the Internet has come to rely almost exclusively on financial institutions serving as trusted third parties to process electronic payments. While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model.

Completely non-reversible transactions are not really possible, since financial institutions cannot avoid mediating disputes. The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, and there is a broader cost in the loss of ability to make non-reversible payments for nonreversible services. With the possibility of reversal, the need for trust spreads. Merchants must be wary of their customers, hassling them for more information than they would otherwise need.

A certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties can be avoided in person by using physical currency, but no mechanism exists to make payments over a communications channel without a trusted party.

What is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party. Transactions that are computationally impractical to reverse would protect sellers from fraud, and routine escrow mechanisms could easily be implemented to protect buyers.”

Blockchain technology: Redefining trust for a global, digital economy

“With Google Trends data showing that searches for the word “blockchain” have exponentially increased, we may be entering the peak of the hype cycle for blockchain and distributed ledger technology.

But here’s the thing: the blockchain is a major breakthrough. That’s because its decentralized approach to verifying changes in important information addresses the centuries-old problem of trust, a social resource that is all too often in short supply, especially amid the current era’s rampant concerns over the security of valuable data. It turns out that fixing that can be a boon for financial inclusion and other basic services delivery, helping to achieve the global objectives laid out in the Sustainable Development Goals (SDGs).”

The Age of Tokenized Ecosystems

“The Age of Tokenized Ecosystems” has begun. This new era directly correlates with the beginning of a new technological boom that is quietly gaining momentum — the decentralization revolution. It may not be so apparent right now, but within a few years we’re going to see the beginning of trillions upon trillions of dollars worth of centralized assets being decentralized and placed on blockchains, predominantly Ethereum’s blockchain. This upcoming technological boom will be as great, if not greater, than the internet boom of the late nineties and tokenized ecosystems will play an important role.

How Blockchain Will Change Your Life

“Until the mid-1990s, the internet was little more than an arcane set of technical standards used by academics. Few predicted the profound effect it would have on society. Today, blockchain—the technology behind the digital currency bitcoin—might seem like a trinket for computer geeks. But once widely adopted, it will transform the world.

Blockchain offers a way to track items or transactions using a shared digital “ledger.” Blocks of new transactions are added at the end of the chain, and encryption ensures that it remains unbroken—tamper-proof and error-free. This is significantly more efficient than the current methods for logging and sharing such information.”

Ginni Rometty, the chairman, president and CEO of IBM
