What if there is a technological advancement so powerful

that it transforms the very basic pillars of our society?

關係子句

A technology which fundamentally influences the way that our economy,

governance systems and businesses function,

and change our conceptual understanding of trade, ownership and trust?

People often think of Bitcoin as only virtual money or a transaction system.

But if you look closer, you’ll see that the monetary aspect,

That’s because Bitcoin is a ground-breaking internet technology

for which money is merely one of the possible applications.

Through the centuries, trade has become incredibly complex.

Everyone trades with everyone, worldwide.

This information is often isolated and closed to the public.

For this reason, we use third parties and middlemen we trust

to facilitate and approve our transactions.

Think of governments, banks, accountants, notaries,

This brings us to the essence of Bitcoin.

Bitcoin’s software enables a network of computers

to maintain a collective bookkeeping via the internet.

This bookkeeping is neither closed nor in control of one party,

and available in one digital ledger which is fully distributed across the network.

In the Blockchain, all transactions are logged including information on the date,

time, participants and amount of every single transaction.

Each node in the network owns a full copy of the Blockchain.

On the basis of complicated state-of-the-art mathematical principles,

the transactions are verified by the so-called Bitcoin Miners,

The mathematical principles also ensure that these nodes

about the current state of the ledger and every transaction in it.

If anyone attempts to corrupt a transaction, the nodes will not arrive at a consensus

and hence will refuse to incorporate the transaction in the Blockchain.

and thousands of nodes unanimously agree that a transaction has occurred

It’s like there’s a notary present at each transaction.

This way, everyone has access to a shared single source of truth.

This is why we can always trust the Blockchain.

whether a bitcoin represents a certain amount of euros or dollars,

or anything else of value or property for that matter.

Users can decide for themselves what a unit of bitcoin represents

A bitcoin is divisable in 100 million units.

And each unit is both individually identifiable and programmable.

This means that users can assign properties to each unit.

Users can program a unit to represent a eurocent,

Because of this, Bitcoin is much more than simply money and payments:

a Bitcoin can represent many kinds of property.

Moreover, Bitcoin allows us to make our currency smarter and to automatize our cash and money flows.

Imagine a healthcare allowance in dollars or euros

that can only be used to pay for healthcare at certified parties.

In this case, whether someone actually follows the rules is no longer verified in the bureaucratic process afterwards.

You simply program these rules into the money.

The unit can even be programmed in such a way

that it will automatically return to the provider

if the receiver doesn’t use it after a certain amount of time.

This way, the provider can ensure that allowances are not hoarded.

A company can control its spending in the same way

by programming budgets for salaries, machinery, materials, and maintenance so

Automizing such matters leads to a considerable decrease in bureaucracy,

and the organization in general an incredible amount of time.

The programmable, open character of Bitcoin

allows us to completely rebuild and innovate

our financial sector and our administrative processes.

our economy will be dealing with machines that actively participate in the economic traffic.

Think of a vending machine. Or drones delivering packages.

These machines are unfamiliar with the concept of trust,

Because of Bitcoin, the drone can be a hundred percent certain

that it will deliver the package to the right recipient

and know for sure that it has been paid for.

And we can program the vending machine in such a way

that it will automatically keep track of its supplies, order new supplies

from the supplier and pay for them automatically.

Of course, you will understand that this is only the beginning.

Internet technology is disruptive and breaks the status quo.
