“The practical consequence […is…] for the first time, a way for one internet user to transfer a unique piece of digital property to another internet user, such that the transfer is guaranteed to be safe and secure, everyone knows that the transfer has taken place, and nobody can challenge the legitimacy of the transfer. The consequences of this breakthrough are hard to overstate.”
– Marc Andreessen
From a cruising altitude, a blockchain might not look that different from other decentralized digital systems – like, say, Wikipedia.
With a blockchain, many people can write entries into a record of information, and a community of users can control how the record of information is amended and updated. Likewise, Wikipedia entries are not the product of a single publisher. No one person controls the information.
Descending to ground level, however, the differences that make blockchain technology unique become more clear. While both run on distributed networks (the internet), Wikipedia is built into the World Wide Web using a client-server network model.
A user (client) with permissions associated with its account is able to change Wikipedia entries stored on a centralized server.
Whenever a user accesses the Wikipedia page, they will get the updated version of the “master copy” of the Wikipedia entry. Control of the database remains with Wikipedia administrators allowing for access and permissions to be maintained by a central authority.
Wikipedia’s digital backbone is similar to the highly protected and centralized databases that governments, banks or insurance companies keep today. Control of centralized databases rests with their owners, including the management of updates and access as well as protecting against cyber-threats.
The distributed database created by blockchain technology has a fundamentally different backbone. While Wikipedia’s “master copy” is edited on a server and all users see the new version, in the case of a blockchain, every node in the network is coming to the same conclusion, each updating the record independently, with the most popular record becoming the de facto official record in lieu of there being a master copy.
It is this difference that makes blockchain technology so useful – it represents an innovation in information registration and distribution that eliminates the need for a trusted party to facilitate digital relationships.
Yet blockchain technology, for all its merits, is not a new technology.
Rather, it is a combination of proven technologies applied in a new way. It was the particular orchestration of three technologies (the internet, private key cryptography and a protocol governing incentivization) that made bitcoin creator Satoshi Nakamoto’s idea so useful.
The result is a system for digital interactions that does not need a trusted third party. The work of securing digital relationships is implicit — supplied by the elegant, simple, yet robust network architecture of blockchain technology itself.
Defining digital trust
Trust is a risk judgement between different parties, and in the digital world, determining trust often boils down to proving identity (authentication) and proving permissions (authorization). Put more simply, we want to know, “Are you who you say you are?” and “Should you be able to do what you are trying to do?”
In the case of blockchain technology, private-key cryptography provides a powerful ownership tool that fulfills authentication requirements. Possession of a private key is ownership. It also spares a person from having to share more personal information than they would need to verify their identity for an exchange, leaving them exposed to hackers.
Authentication is not enough. Authorization – having enough money, broadcasting the correct transaction type, etc – needs a distributed, peer-to-peer network as a starting point. A distributed network reduces the risk of centralized corruption or failure. This distributed network must also be committed to the transaction network’s record-keeping and security. Authorizing transactions is a result of the entire network applying the rules upon which it was designed (the blockchain’s protocol). Authentication and authorization supplied in this way allow for interactions in the digital world without relying on (expensive) trust.
The idea can be applied to any need for a trustworthy system of record.
Blockchain technology is often described as the backbone for a transaction layer for the internet, the foundation of the Internet of Value. Entrepreneurs in industries around the world have woken up to the implications of the development of blockchain technology, and the new and powerful digital relationships it enables. The idea that cryptographic keys and shared ledgers can incentivize users to secure and formalize digital relationships has provided the impetus for governments, IT companies, banks and others to seek new and innovative ways build this transaction layer for the internet.

Fool me once shame on you. Fool me twice, shame on me, the saying goes. It all comes back to the breakdown of the monetary system and the moral hazard introduced by a financial system that spawned as a result of misaligned monetary incentives. There is no mistaking it; the instability in the broader economic system is a function of the monetary system, and as more of these episodes continue to play out, more and more people will continue to seek a better, more sustainable path forward. Now with bitcoin increasingly at center stage, there is a market mechanism that will de-financialize and heal the economic system. The process of definancialization will occur as wealth stored in financial assets is converted into bitcoin and as each market participant increasingly expresses a preference for holding a more reliable form of money over risk assets. Definancialization will principally be observed through growing bitcoin adoption, the appreciation of bitcoin relative to every other asset and the deleveraging of the financial system as a whole. Almost everything will lose purchasing power in bitcoin-denominated terms as bitcoin becomes adopted globally as a monetary standard. Most immediately, bitcoin will gain share from financial assets, which have acted as near stores of value; it is only logical that the assets which have long served as monetary substitutes will increasingly be converted to bitcoin. As part of this process, the financial system will shrink in size relative to the purchasing power of the bitcoin network. The existence of bitcoin as a more sound monetary standard will not only cause a rotation out of financial assets, but bitcoin will also impair future demand for the same type of assets. Why purchase near-zero yielding sovereign debt, illiquid corporate bonds or equity-risk premium when you can own the scarcest asset (and form of money) that has ever existed?bitcoin base продать monero надежность bitcoin

According to the World Bank, around 80% of people in Indonesia, the Philippines, and Vietnam, and 30% in Malaysia and Thailand, are unbanked. In Myanmar, only 23% of people have a legit bank account. CBDC can help create an inclusive financial system.What Is Bitcoin?
