How Litecoin Began
What is Litecoin Charlie LeeLitecoin was first created in 2011 by an ex-Google employee called Charlie Lee. Like many other blockchain lovers, Charlie Lee believed that the Bitcoin code had too many flaws.
These flaws related to:
Bitcoin’s failure to speed up transactions;
The way it was mined (explained later);
Its ability to perform more transactions per second - scalability.
Scalability: When I use this term, I'm are talking about the number of transactions that a blockchain can process per second. As more and more people use a blockchain, the network can become overcrowded and transaction speeds might slow down! For example, Bitcoin is scalable to a maximum of 7 transactions per second!
For Charlie Lee to achieve his goal of creating a lighter version of Bitcoin, he needed to perform something called a hard fork. This is where things get really interesting!
A fork is when changes are made to an original blockchain to make it better. To make things even more confusing (sorry), there are two types of forks!
A soft fork is when an upgrade is made to a blockchain, but the new block rules are still recognized by the older version. Many soft forks have been made to the Bitcoin blockchain.
What is Litecoin: a Litecoin on a keyboard.
However, as Bitcoin is decentralized, it means that no single person has control over it. If new changes are to be made, it goes to a voting system. Only if enough people vote in favor of a new change, it can go ahead. If not, then it won’t!
The second type of fork is a hard fork. This is when really big changes are needed, and the only way to achieve it is to create a separate blockchain! This is exactly what Charlie Lee did with Litecoin!
We will explain more on this later, but first, let’s try and answer the key question – “what is Litecoin?!”
What is Litecoin?
There are still many similarities between Litecoin and Bitcoin, which is why it is referred to as the silver to Bitcoin’s gold!
What is LitecoinIts main purpose is to become a global payment system. This means that people can send and receive funds locally or internationally, without needing to use a third party (such as a bank).
To be able to answer “what is Litecoin?”, it is important to understand the real-world problem it is trying to solve.
For example, imagine that John (who lives in the UK) wanted to send Bob (who lives in Kenya) some funds. If using a bank, it would:
Be really expensive.
Take days to arrive.
Require John to fill out lots of forms.
However, if John decides to use Litecoin to make the payment, he can avoid all of these issues.
Firstly, the cost of sending a Litecoin is very cheap. In fact, it costs just a few cents to send funds!
Secondly, Litecoin transactions only take 2.5 minutes to arrive, which is much quicker than a bank transfer. It doesn’t matter if you want to send coins to someone on your street, or to someone on the other side of the world — it literally takes minutes for the funds to arrive!

Thirdly, as Litecoin is decentralized, you have full control over your funds. This means that you do not need to fill out any forms to send your coins!
These benefits make Litecoin a great alternative for sending and receiving funds. So, now that you can answer the question “what is Litecoin?”, let’s find out how the technology works!

Decentralization is the means, not the end. By distributing power as widely as possible we minimize the trust required in any single entity because we know that no single entity can interfere with our use of the system.алгоритм monero bitcoin litecoin key bitcoin iso bitcoin bitcoin индекс fpga bitcoin bitcoin poloniex ethereum shares казино ethereum bitcoin currency ethereum calc coin bitcoin

monero gui A financial contract works by taking the median of nine proprietary data feeds in order to minimize risk. An attacker takes over one of the data feeds, which is designed to be modifiable via the variable-address-call mechanism described in the section on DAOs, and converts it to run an infinite loop, thereby attempting to force any attempts to claim funds from the financial contract to run out of gas. However, the financial contract can set a gas limit on the message to prevent this problem.криптовалюта ethereum bitcoin flex bitcoin ocean bitcoin course bitcoin hardfork валюта monero 2016 bitcoin

кошелька ethereum bitcoin car ccminer monero bitcoin картинки ethereum капитализация bitcoin hashrate Once step (1) has taken place, after a few minutes some miner will include the transaction in a block, say block number 270. After about one hour, five more blocks will have been added to the chain after that block, with each of those blocks indirectly pointing to the transaction and thus 'confirming' it. At this point, the merchant will accept the payment as finalized and deliver the product; since we are assuming this is a digital good, delivery is instant. Now, the attacker creates another transaction sending the 100 BTC to himself. If the attacker simply releases it into the wild, the transaction will not be processed; miners will attempt to run APPLY(S,TX) and notice that TX consumes a UTXO which is no longer in the state. So instead, the attacker creates a 'fork' of the blockchain, starting by mining another version of block 270 pointing to the same block 269 as a parent but with the new transaction in place of the old one. Because the block data is different, this requires redoing the proof of work. Furthermore, the attacker's new version of block 270 has a different hash, so the original blocks 271 to 275 do not 'point' to it; thus, the original chain and the attacker's new chain are completely separate. The rule is that in a fork the longest blockchain is taken to be the truth, and so legitimate miners will work on the 275 chain while the attacker alone is working on the 270 chain. In order for the attacker to make his blockchain the longest, he would need to have more computational power than the rest of the network combined in order to catch up (hence, '51% attack').bitcoin telegram bitcoin sec ethereum продам
