How are Transactions Confirmed on the Blockchain?
You might remember how I explained earlier that the blockchain is decentralized, meaning that no single authority has control over the network. This also means that the blockchain does not need a third party intermediary to confirm a movement of funds.
If that’s the case, how are transactions confirmed? This is where things get really interesting!
The blockchain is a community-based platform, meaning that in most cases, anybody can contribute to the network to help verify transactions. They do so by contributing their computational power, which in return, is able to support the network.
Not all blockchains use the same technology to do this, but we differentiate the process by how the network reaches “consensus”. Consensus basically means “How does the network know that the transaction is valid and that the user actually has the funds available?”
Blockchains reach consensus by following the rules of “cryptography”, which is where the term “cryptocurrency” comes from. Cryptography is a really advanced area of mathematics that is based on algorithmic puzzles.
When the blockchain and its community of volunteers are able to solve the algorithmic puzzle, the rules of cryptography state that a transaction is valid and authentic. However, different blockchains use different methods to solve the puzzle, which is known as a “consensus mechanism”.
Confused? Don’t be, as my “What is blockchain” guide is now going to give you an example!
The blockchain Bitcoin uses is supported by a consensus mechanism called “Proof-of-Work” (PoW). The puzzle is so difficult that no human being could solve it on their own, which is why people need to use their computational power instead.
Every computer that is connected to the network (called a “Node”) attempts to solve the puzzle as quickly as possible. Whoever solves the puzzle first, gets a reward – free, new Bitcoin. However, in reality, the Bitcoin reward is not free, as the user had to use their surplus computational power, which consumes lots of electricity!
PoW is just one example of how a blockchain reaches consensus. There are many others and I have listed some of them below (there are lots more)!
PoS (Proof of Stake)
DPoS (Delegated Proof of Stake)
PBFT (Practical Byzantine Fault Tolerance)
DAG (Directed Acyclic Graph)
Are you still asking yourself “What is blockchain”? I hope not! The next part of my blockchain tutorial is going to talk about why decentralization is important!

You’ll also need a place in which your community can talk to one another and ask you questions. The most popular app to use for this is Telegram. It is an instant messaging app, like WhatsApp or Facebook Messenger. However, it is known for its security and has become a very trusted, favored app in the crypto world.bitcoin motherboard bitcoin investment monero *****uminer ethereum телеграмм fork ethereum monero майнить bittorrent bitcoin ethereum пул agario bitcoin bitcoin lucky monero amd escrow bitcoin

In the majority they are right. Do not try to refer Bitcoin to something exact - it would make no sense. Try to embrace every piece of the information.bitcoin waves bitcoin stiller As *****, we all learn that money doesn’t grow on trees. As a society on the other hand, we have become conditioned to believe that it’s not only possible but that it’s a normal, necessary and productive function of our economy. Before bitcoin, this privilege was reserved to global central banks (see here for example). Post bitcoin, every Tom, Dick %trump2% Harry seems to think that they can create money too. At a root level, this is the audacity of everyone that attempts to create a copy of bitcoin. Whether by hard-forking out of consensus (bitcoin cash), cloning bitcoin (litecoin) or creating a new protocol with 'better' features (ethereum), each is an attempt to create a new form of money. If bitcoin could do it, why can’t we?Fundamentalsмонета ethereum bitcoin ферма bitcoin покупка boom bitcoin зарегистрировать bitcoin

Their services are mainly aimed at institutional investors, such as hedge funds, who hold large amounts of bitcoin or other cryptocurrencies. The solutions generally incorporate a combination of hot storage, or crypto custody with connection to the Internet, and cold storage, or crypto custody that is disconnected from the Internet. bitcoin switzerland bitcoin обсуждение network bitcoin bitcoin bazar основатель bitcoin bitcoin сервера ethereum рост ethereum russia nicehash monero график monero bitcoin кошелек проверка bitcoin forum ethereum tether plugin bitcoin plugin ethereum asics bitcoin расшифровка mt5 bitcoin tor bitcoin
