Litecoin followed in Created by Charles Lee, an engineer who later helped build Coinbase , the leading cryptocurrency exchange, Litecoin is based on the same code as bitcoin but with a few tweaks designed to address two of its predecessor's limitations: transaction speed and access to the mining process.
And in , Ethereum made its debut, incorporating bitcoin's basic blockchain premise and Litecoin's pursuit of faster transaction speed, but adding a few of its own twists -- including the ability to process little chunks of code, called "smart contracts" -- and on its virtual peer-to-peer network as opposed to a dedicated server or mining rig.
Coinbase's support for bitcoin, Litecoin and Ethereum -- as well as Bitcoin Cash , a new branch of the bitcoin blockchain created in August -- helped install and keep them among the most visible and well-capitalized cryptocurrencies. Rounding out the top 10, in terms of market capitalization, is a dynamic shortlist that has included established coins and upstarts like Ripple , Cardano , Neo , Stellar , Eos and IOTA. For the purposes of introducing some of the prevailing concepts behind the growing population of cryptocurrencies, we'll take a closer look at the technologies behind Litecoin and Ethereum, how they compare to bitcoin and what they each bring to the table for prospective investors, miners and traders.
Litecoin is closely based on bitcoin -- they're built on the same underlying code -- but with a few distinctive tweaks. The central difference is that Litecoin is mined using the Scrypt algorithm , which is rooted in mathematical computations that are simpler than those used by bitcoin's SHA algorithm. As a result, in contrast to the specialized, super-expensive, energy-intensive mining rigs required to mine bitcoin, you can mine Litecoin with a decent laptop or desktop PC, especially if it's tricked out with a powerful graphics card.
And because Scrypt is less mathematically complex than SHA, Litecoin mining is way faster than bitcoin mining. A Litecoin block takes only 2. So Litecoin transactions are also faster to process and confirm. Like Litecoin, it's based on the same fundamental blockchain concept as bitcoin, with blocks and hashes and such , but Ethereum adds its own distinctive twist. Funded in through an initial coin offering , Ethereum fancies itself "an enormously powerful shared global infrastructure" that, in addition to serving as a digital currency, runs special applications called "smart contracts.
This collective, distributed computing network, called the "Ethereum Virtual Machine," can be, in a sense, rented out. Participants who consume computing power pay for it with tokens, called Ether; those who contribute processing power can earn them. Of course, buyers and sellers can simply trade Ether independently of these activities. Consider that bitcoin mining is akin to thousands of chefs feverishly racing to prepare a new, extremely complicated dish -- and only the first one to serve up a perfect version of it ends up getting paid.
In the Ethereum kitchen, miners serve as the restaurant's landlord, compensated for providing the infrastructure so that Ether chefs can invent new types of cuisine. In fact, a group of companies and universities has formed a nonprofit expressly to legitimize Ethereum; promote it as an open-source platform and not a commercial enterprise per se; and develop and support those applications that run on it.
And these are not rinky-dink startups -- we're talking about major technology players like Intel and Microsoft and financial behemoths like JP Morgan and Credit Suisse. Bitcoin remains the most visible and frequently traded cryptocurrency. If only it was that easy. No one knows whether any cryptocurrency will increase in value -- or even be around in a year's time though we think the ones outlined in this article will check both of those boxes.
None of them are regulated yet and only individuals with the highest capacity for risk should get into the cryptocurrency market.

The total number of Bitcoin that will ever exist is limited to 21 million. Satoshi Nakamoto is the name used by a person or persons who developed Bitcoin, authored the bitcoin white paper, the first blockchain database, and created and deployed Bitcoin's original program. Launched by former Google engineer Charlie Lee, as a " lite version of Bitcoin " created in reaction to Bitcoin.
Should you base all your investing decisions on this one Byte? Litecoins speed and cheapness make it ideal for smaller, everyday transactions. Unlike bitcoin which is more similar to investing in gold. They both use similar blockchain technology where transactions are verified by computers called mining that can be owned by anyone and protects it from counterfeiting.
The most fundamental technical difference between Bitcoin and Litecoin is the different cryptographic algorithms. Bitcoin is very limited in this sense as it can only process an average of 7 transactions per second. If it is going to be used as a global payment system, it must improve its performance as more people use the currency. Bitcoin is limited by transaction processing time, an issue that has caused division within the bitcoin mining and developing communities.
Litecoin was founded with the goal of prioritizing transaction speed, helping it grow and gain popularity. Litecoin networks have a 2. Important note: Always do further, independent research, and always consult a financial investor before investing.
Also, keep in mind that it's crucial to keep your cryptocurrencies in secure digital wallets , such as Ledger Nano S , Trezor Model T, and Coinbase. Bitcoin Cash and Litecoin are mined in the same way, every time a computer is used to verify a transaction, trade, or sale; they are rewarded with "tokens" another word for cryptocurrencies. Mining Bitcoin Cash makes much less profit than mining Bitcoin with the same equipment because Bitcoin is more valuable.
The minimum quantity of transferable Bitcoin is one hundred millionth of a bitcoin 0. You can convert Litecoins to Bitcoins, and vice versa—similar to the way you can exchange traditional currencies, like changing dollars into pounds, or yen into euros. To do so, you need to have an account with a cryptocurrency trading or exchange platform or trading app.
The amount you'll receive in the conversion depends on the current prices for each currency. All cryptocurrencies generate huge volumes of carbon emissions. Some of this energy is from renewable sources but mining is often done in the least expensive ways to increase profits.
A single transaction of bitcoin, for example, has the same carbon footprint as , Visa transactions or bingeing YouTube for 51, hours. Litecoin uses a simpler transaction process with smaller blocks files which leads to less processing power than Bitcoin for the same task. Less research has been done on the Scrypy cryptography algorithm but people are slowly becoming more aware of its environmental impact.
Bitcoin is older , slower, and costs a lot more per transaction. It is likely that as the sector grows, Bitcoin will continue to lose its dominance over these other coins. The core development team of Bitcoin appears to be divided as a group and lacking clear leadership compared to other crypto teams, like Ethereum. Litecoin is less popular and does not have as much investor confidence as Bitcoin.
Extremely volatile - Bitcoin and Litecoin prices can drop very quickly and reach very low prices. Illegal Activity - all Cryptocurrencies can be used in the black market and for illegal activities because there is anonymity. Which of these have been used for illegal activities?

Blockchains are not silver bullets to every problem.
In being optimized for the advantages in the previous section, they end up lacking in other areas. This is true of any distributed network. Therefore, developers tend to intentionally limit the speed at which the blockchain can update to ensure that the system remains decentralized. For users of a network, this can manifest itself in lengthy waiting periods if too many people are trying to make transactions. If there are more transactions than can fit in the block, then any additional ones must wait for the next block.
In an environment with potentially millions of users, making changes is considerably more difficult. If the modified software is incompatible with other nodes, they will recognize this and refuse to interact with your node. Suppose you wanted to change a rule about how big blocks can be from 1MB to 2MB.
If they receive anything bigger, they will not include it in their copy of the blockchain. We know that nodes are interconnected and that they store copies of the blockchain. They communicate information about transactions and new blocks to each other. Because all nodes have equal power, there needs to be a mechanism for fairly deciding who can add blocks to the blockchain.
We need a system that makes it expensive for users to cheat but rewards them for acting honestly. Any rational user will want to act in a way that is economically beneficial to them. Because the network is permissionless, block creation needs to be accessible to anyone. The puzzle requires users to hash transactions and other information included in the block.
But for the hash to be considered valid, it must fall below a certain number. When a miner sends a new block to the rest of the network, all the other nodes use it as the input in a hash function. They simply need to run it once to verify that the block is valid under the rules of the blockchain. Since its creation, many other blockchains have adopted the PoW mechanism. Different implementations have different variations, but once a validator stakes their units, they can be randomly selected by the protocol to announce the next block.
Alternatively, there might be multiple validators that agree on the next block, and a reward is distributed proportionately to the stake each has put forward. A number of different solutions have been either proposed or implemented to mitigate some of the performance drawbacks of blockchains.
There may be clear advantages to both. On-chain scaling solutions could be reducing the size of transactions, or even just optimizing how data is stored in blocks. On the other hand, off-chain solutions involve batching transactions off of the main blockchain, and only adding them later. Some of the most notable off-chain solutions are called sidechains and payment channels.
If blockchain systems are to compete with their centralized counterparts, they need to be at least as performant as them. This means that when compared to centralized systems, using blockchains needs to be faster, cheaper, and easier both for developers and users. Bear in mind that blockchains are distributed networks. Once the software is upgraded, thousands of nodes scattered around the world need to be able to communicate and implement the new version. This leads us to soft and hard forks.
This is called a soft fork. A hard fork is more complicated. Once implemented, the new rules will be incompatible with the old rules. This results in the blockchain splitting into two — in one, the old software is running, in the other, the new rules are implemented. After the hard fork, there are essentially two different networks running two different protocols in parallel.
Efficient supply chains are at the core of many successful businesses and concern themselves with the handling of goods from the supplier to the consumer. The coordination of multiple stakeholders in a given industry has traditionally proven difficult. However, blockchain technology could allow for new levels of transparency in many industries. An interoperable supply chain ecosystem that revolves around an immutable database is just what many industries need to become more robust and reliable.
The gaming industry has become one of the biggest entertainment industries in the world, and it could greatly benefit from blockchain technology. Typically, gamers tend to be at the mercy of game developers. In this context, blockchain could help decentralize the ownership, management, and maintenance of online games.
Storing medical records in a reliable manner is vital for any healthcare system, and the reliance on centralized servers leaves sensitive information in a vulnerable position. The transparency and security of blockchain technology make it an ideal platform on which to store medical records. In cryptographically securing their records on a blockchain, patients could maintain their privacy, while being able to share their medical information with any healthcare institution.
If all participants of the currently fragmented healthcare system could tap into a secure, global database, information flow would be much faster between them. Sending money internationally is a hassle with traditional banking. Predominantly due to a convoluted network of intermediaries, the fees and settlement times make using traditional banks both expensive and unreliable for urgent transactions. Cryptocurrencies and blockchains eliminate this ecosystem of middlemen and can allow for cheap, rapid transfers around the world.
While blockchains undoubtedly sacrifice performance for some of their desirable properties, a range of projects are harnessing the technology to allow for cheap, near-instant transactions. This type of cryptographic magic could allow for a smoother experience online without sacrificing privacy. Distributed networks can define and enforce their own forms of regulation in the shape of computer code.
Charity organizations are often impeded by the limitations of how they can accept funds. Even more frustratingly, the ultimate destination of the donated funds can be hard to precisely track, which undoubtedly discourages many from supporting these organizations.
Undoubtedly, one of the most popular uses of blockchain technology is speculation. Frictionless transfers between exchanges, non-custodial trading solutions, and a growing ecosystem of derivatives products make it an ideal playing field for all types of speculators. Due to its inherent properties, blockchain is an excellent instrument for those willing to take the risk of participating in such a sprouting asset class.
Some even think that once the technology and the surrounding regulation matures, the global speculative markets may all be tokenized on the blockchain. Distributing file storage on the Internet has many benefits compared to conventional centralized alternatives. Much of the data stored in the cloud relies on centralized servers and service providers, which tend to be more vulnerable to attacks and data loss.
In some cases, users may also face accessibility problems due to censorship from centralized servers. From the user perspective, blockchain file storage solutions work just like other cloud storage solutions — you can upload, store, and access files. In some cases, each node will store a different portion of your file. The storage space derives from the participants who provide their storage and bandwidth to the network.
You could think of this type of network as one similar to Bitcoin. What Is Blockchain Technology? The Ultimate Guide. Table of Contents. Chapter 1 - Blockchain A blockchain is a special type of database. You may also have heard the term distributed ledger technology or DLT — in many cases, they're referring to the same thing.
Data is added over time in structures called blocks. Each block is built on top of the last and includes a piece of information that links back to the previous one. By looking at the most up-to-date block, we can check that it has been created after the last. So if we continue all the way down the "chain," we'll reach our very first block — known as the genesis block.
The first cell's data is converted into a two-letter identifier, which will then be used as part of the next input. In this example, the two-letter identifier KP must be used to fill out the next cell in the second row defKP. This means that if you change the first input data abcAA , you'd get a different combination of letters in every other cell.
Looking at row 4 now, our most recent identifier is TH. Remember how we said you can't go back and remove or delete entries? That's because it would be easy for anyone to tell that it's been done, and they'd just ignore your attempted change. Suppose you change the data in the very first cell — you'd get a different identifier, which would mean your second block would have different data, leading to a different identifier in row 2, and so on.
TH is, in essence, a product of all the information coming before it. What we discussed above — with our two-letter identifiers — is a simplified analogy of how a blockchain uses hash functions. Hashing is the glue that holds blocks together. It consists of taking data of any size and passing it through a mathematical function to produce an output a hash that's always the same length.
Input data SHA output Binance Academy c5fd21bad24f2eaff5c0df42d5fa56d04dccaf3 Binance academy aadebf6dd94eddc2fcfd8edd2ca7 binance academy acd8adebec6bec34bc86eacc3cf8bf5bab The fact that there aren't any known SHA collisions i. It means that each block can point back to the previous one by including its hash, and any attempt to edit older blocks will immediately become apparent. As standalone data structures, blockchains are only really useful in niche applications.
Where things get interesting is when we use them as tools for strangers to coordinate amongst themselves. Combined with other technologies and some game theory , a blockchain can act as a distributed ledger that's controlled by no one. What this means is that no one has the power to edit the entries outside of the rules of the system more on the rules shortly.
In that sense, you could argue that the ledger is simultaneously owned by everyone : participants reach an agreement on what it looks like at any given moment. The real challenge standing in the way of a system like that described above is something called the Byzantine Generals Problem. Conceived in the s, it describes a dilemma in which isolated participants must communicate to coordinate their actions.
The specific dilemma involves a handful of army generals that surround a city, deciding whether to attack it. The generals can only communicate via messenger. To overcome the potential failure of one or several users, the mechanisms of the blockchain must be carefully engineered to be resistant to such setbacks. A system that can achieve this is referred to as Byzantine fault-tolerant. As we'll see shortly, consensus algorithms are used to enforce robust rules.
Be sure to check out Peer-to-Peer Networks Explained for a more in-depth discussion of this type of network. The above describes what a node is in the purest sense, but the definition can also encompass other users that interact with the network in any way. In cryptocurrency, for instance, a simple wallet application on your phone is what's known as a light node.
Bitcoin is what we call a public blockchain. This means that anyone can view the transactions on it, and all it takes to join is an Internet connection and the necessary software. Since there aren't any other requirements for participation, we may refer to this as a permissionless environment. In contrast, there are other types of blockchains out there called private blockchains.
These systems establish rules regarding who can see and interact with the blockchain. As such, we refer to them as permissioned environments. While private blockchains may seem redundant at first, they do have some important applications — mainly in enterprise settings. If Alice wants to pay Bob via bank transfer, she notifies her bank. The bank checks that Alice has the funds to perform the transaction, before updating its database e.
