As stated in our guide “What is Blockchain Technology?”, there are three principal technologies that combine to create a blockchain. None of them are new. Rather, it is their orchestration and application that is new.
These technologies are: 1) private key cryptography, 2) a distributed network with a shared ledger and 3) an incentive to service the network’s transactions, record-keeping and security.
The following is an explanation of how these technologies work together to secure digital relationships.
Cryptographic keys
Two people wish to transact over the internet.
Each of them holds a private key and a public key.
The main purpose of this component of blockchain technology is to create a secure digital identity reference. Identity is based on possession of a combination of private and public cryptographic keys.
The combination of these keys can be seen as a dexterous form of consent, creating an extremely useful digital signature.
In turn, this digital signature provides strong control of ownership.
But strong control of ownership is not enough to secure digital relationships. While authentication is solved, it must be combined with a means of approving transactions and permissions (authorisation).
For blockchains, this begins with a distributed network.
A Distributed Network
The benefit and need for a distributed network can be understood by the ‘if a tree falls in the forest’ thought experiment.
If a tree falls in a forest, with cameras to record its fall, we can be pretty certain that the tree fell. We have visual evidence, even if the particulars (why or how) may be unclear.
Much of the value of the bitcoin blockchain is that it is a large network where validators, like the cameras in the analogy, reach a consensus that they witnessed the same thing at the same time. Instead of cameras, they use mathematical verification.
In short, the size of the network is important to secure the network.
That is one of the bitcoin blockchain’s most attractive qualities — it is so large and has amassed so much computing power. At time of writing, bitcoin is secured by 3,500,000 TH/s, more than the 10,000 largest banks in the world combined. Ethereum, which is still more immature, is secured by about 12.5 TH/s, more than Google and it is only two years old and still basically in test mode.
System of record
When cryptographic keys are combined with this network, a super useful form of digital interactions emerges. The process begins with A taking their private key, making an announcement of some sort — in the case of bitcoin, that you are sending a sum of the cryptocurrency — and attach it to B’s public key.
Protocol
A block – containing a digital signature, timestamp and relevant information – is then broadcast to all nodes in the network.
A realist might challenge the tree falling in the forest thought experiment with the following question: Why would there be a million computers with cameras waiting to record whether a tree fell? In other words, how do you attract computing power to service the network to make it secure?
For open, public blockchains, this involves mining. Mining is built off a unique approach to an ancient question of economics — the tragedy of the commons.
With blockchains, by offering your computer processing power to service the network, there is a reward available for one of the computers. A person’s self-interest is being used to help service the public need.
With bitcoin, the goal of the protocol is to eliminate the possibility that the same bitcoin is used in separate transactions at the same time, in such a way that this would be difficult to detect.
This is how bitcoin seeks to act as gold, as property. Bitcoins and their base units (satoshis) must be unique to be owned and have value. To achieve this, the nodes serving the network create and maintain a history of transactions for each bitcoin by working to solve proof-of-work mathematical problems.
They basically vote with their *****U power, expressing their agreement about new blocks or rejecting invalid blocks. When a majority of the miners arrive at the same solution, they add a new block to the chain. This block is timestamped, and can also contain data or messages.
The type, amount and verification can be different for each blockchain. It is a matter of the blockchain’s protocol – or rules for what is and is not a valid transaction, or a valid creation of a new block. The process of verification can be tailored for each blockchain. Any needed rules and incentives can be created when enough nodes arrive at a consensus on how transactions ought to be verified.
It’s a taster’s choice situation, and people are only starting to experiment.
We are currently in a period of blockchain development where many such experiments are being run. The only conclusions drawn so far are that we are yet to fully understand the dexterity of blockchain protocols.
More on this point in our guides “What are Applications and Use Cases for Blockchain Technology?” and “What is the Difference Between Open and Permissioned Blockchains?”

Is it a type of currency, a store of value, a payment network or an asset class?Bitcoin solved this problem via a global ledger that all network participants must agree upon. There are some very sophisticated game-theoretical incentives built into the system to keep everyone honest and using the same version of the ledger. I won’t dive too much deeper into the details of how this works, but every ten minutes a new 'block' of transactions is added to the ledger. If your transaction is included in that block, then the network will not accept an attempt to double-spend. This is because the network is now in agreement that you no longer own that unit of e-cash.Speed and low fees should make it attractive for individuals to use Litecoin for peer-to-peer transfers and digital purchases, and for businesses – as a payment system. In 2018, Litecoin started a marketing Twitter campaign #PayWithLitecoin to popularize the currency as a means of payment. However, the list of businesses accepting it remains limited.icons bitcoin

Later that year, on 31 October, a link to a paper authored by Satoshi Nakamoto titled Bitcoin: A Peer-to-Peer Electronic Cash System was posted to a cryptography mailing list. This paper detailed methods of using a peer-to-peer network to generate what was described as 'a system for electronic transactions without relying on trust'. On 3 January 2009, the bitcoin network came into existence with Satoshi Nakamoto mining the genesis block of bitcoin (block number 0), which had a reward of 50 bitcoins.

Path-dependence ensures that those who try to game Bitcoin get burned. Reinforced by four-sided network effects, it makes Bitcoin’s first-mover advantage seemingly insurmountable. The idea of absolute monetary scarcity goes against the wishes of entrenched power structures like The Fed: like zero, once an idea whose time has come is released into the world, it is nearly impossible to put the proverbial genie back in the bottle.

With that bedrock, it does not require a lot of imagination to see how bitcoin evolves from a volatile novelty into a stable economic juggernaut. A hard-capped monetary supply versus endless debasement; a currency that becomes exponentially more expensive to produce compared to a currency whose cost to produce is anchored forever at zero by its very nature. At the end of the day, a currency whose supply (and derivatively its price system) cannot be manipulated. Fundamental demand for bitcoin begins and ends at this singular cross-section. One by one, people wake up and recognize that a bill of goods has been sold, always by some far away expert and never reconciling with day-to-day economic reality. reverse tether bitcoin суть abi ethereum bitcoin вклады dark bitcoin bitcoin airbit ethereum node
