Siacoin

What is Siacoin?

Siacoin (abbrev Sia) is a decentralized platform that uses blockchain technology to help secure and store data safely. It is also a cryptocurrency designed to facilitate payment for data storage in the Sia platform.

The system was created by Vorick David and Luke Champine of Nebulous Inc who wanted to disrupt the data storage market. They conceived the idea in 2013 at HackMIT by making a proposition that with the right platform, any person on the globe could lend unused drive space for a pay.

Siacoin employs file contracts to facilitate operation and payment between hosts (nodes with drive space to lend) and users (clients).

It provides a new way of looking at data-centers so that all people can become part of a huge global ecosystem where data can be stored in a decentralized manner with no risk of loss, abuse, or unauthorized access.

What is the problem that Siacoin Solves?

For more than three decades, the problem of big data has grown from bad to worse.

In a standard setting, companies, organizations, institutions, research firms, and government departments generate huge volumes of data every day, monthly and annually.

Capturing this data, storing, analyzing, searching, and sharing it is a great problem. Think of a person who wants a health-related file about his treatment in 1995 from a government institution amidst progressively piling data. It can be herculean.

Managing this huge data to guarantee harmonic transfer, querying, and even updating is complex and near impossible in many cases. The advent of cloud services was seen as a reliable solution to the problem of big data. But the cloud services are in the hands of a few big corporations such as Google, Facebook, Microsoft, Apple, and Amazon. The centralized enterprises or data-centers comes with many problems;

  • Storing data in the centralized data centers is very expensive.
  • The profit from such services only goes to a few companies.
  • The risk of attack and loss is very high.
  • Data stored in some services such as Google Drive or Dropbox can easily be accessed by third parties because it is not encrypted.

How does Siacoin Solve the problem?

The primary goal of Siacoin is taking away the monolithic providers head on and handing the power to individuals.

This implies that anyone with some extra drive space in a computer can rent it out to others who need it for a pay. Then, the service is paid in Siacoin.

The Siacoin storage ecosystem

The Siacoin system should be seen to largely comprise of two main parties; the providers (hosts) and clients (users). The Siacoin file ecosystem allows users to rent space from hosts and pay for it based on a free-market driven model. The provider is allowed to set the price and conditions for use. However, these must go in line with the Siacoin contract system.

On their side, clients (users) also have a raft of measures created to protect their interests. For example, the data is split data into small bits and secured with multiple providers to enhance its security and retrievability.

Think of a situation where the provider refuses to release data, his computer gets damaged or even moves abroad. In such a case, it will still be possible to retrieve the data from other decentralized nodes.

The file contract system

For the host and user to work in cohesion, Siacoin uses a file contract that both parties have to agree on. The users agree to pay a specific amount of money (in Siacoin) to store data for a specific period. The host is also required to deposit some money on the Siacoin system at the beginning of the contract as collateral. At the close of the contract, the host is paid the collateral and the fee that the user paid.

The proof of storage

It is prudent to note that even with this contract system, Siacoin system does not trust hosts. If the host is paid in advance, he might opt to run away with user data. For others, their systems can get damaged and, ultimately making it impossible for the user to retrieve it.

Therefore, the Siacoin system only pays the host their collateral and fee from the client after presenting proof of storage.

This is a demonstration that you actually stored the data and made it available to the user in line with the file contract. Once the proof of storage is provided, both the collateral and the fee you charged the user are paid to your wallet in Siacoin.

What makes Siacoin better than it’s competitors?

From the moment that Siacoin was conceived, the founders were ready to take on some of the heaviest tech giants in the industry. But the approach taken by Siacoin starts by demonstrating the huge problem of big data and crafts a workable long-term strategy. Here are the main reasons why Siacoin is better than its competitors.

  • Siacoin provides a cheaper and reliable way of storing data across the globe. Because it is a completely decentralized storage platform, users are assured of getting their data cheaply and reliably.
    Most centralized companies such as Amazon and Microsoft are very expensive especially for users with mild data storage needs. For example, storing 1 TB of data at Siacoin is about $2 while Amazon charges more than $40 for the same service every month.
  • Siacoin guarantees users of utmost security. By adopting strict measures requiring the hosts to put forward collateral, users are assured of utmost greater protection.
    Data is also split and stored in many nodes from the principle that none of them can be trusted. In centralized Datacenters, a single point of failure can compromise a lot of clients’ data.
  • As a digital currency, joining the Siacoin network to rent or host users’ data implies there is a huge opportunity for growth. As one of the high potential cryptocurrencies in the market, holding Siacoin can generate huge returns when the price takes an upward shift.
  • Because Siacoin is an open source project, a lot of developers are always working on new ways of improving the network. This is why it gained a lot of following within a few years of establishment. After a successful debut on the files storage system and achieving great success, other projects that are already generating huge interest include file sharing, file recovery, and streaming services features.

How can Siacoin be categorized?

Siacoin is a truly decentralized platform ushering in a revolution in the data storage niche.

While the industry has been so lucrative, every effort made by the monolithic giants is aimed at funneling more profits to their accounts. But the blockchain technology is here and offering a reliable and affordable alternative. By creating a platform that every person can join and participate in data storage, Siacoin has already set in motion a revolution.

  1. A lot of people who have some unused space in their computers will want to make some extra funds. This is as simple as joining the Siacoin network and following the procedure for renting unused hard drive.
  2. For those with some cash to invest, setting up a sizeable storage center can become a money spinner. For example, planning to rent about 500 TB can add about 1000 USD or more every month.
  3. Even as you seek to become a host or user in the Siacoin network, the decentralized network provides users with additional opportunity of earning from the network. You can act as a miner. Because Siacoin uses Proof of Work (PoW) algorithm, you can get a computer to mine the network and simultaneously rent the storage space to users.

Siacoin’s and Security?

The biggest issue for entities dealing with data is keeping it safe. As a data storage platform and cryptocurrency, it implies that the burden for security is more; protecting the client data and securing the network. Here are the main methods used to guarantee Siacoin users of utmost security.

Siacoin goes beyond Reed Solomon coding model to address redundancy

When users come to the Siacoin platform, they expect that their information and data will be secure. Siacoin delivers this by breaking the information into several pieces and storing it in different computers. In an ordinary Reed Solomon coding model when M-of-N can be referred to recover information, the redundancy is only N/M.

Instead of Siacoin going for 1-of-3, it opts for 10-of-30 nodes to achieve the same redundancy of 3X. The chances of 21 drives of the selected 30 failing are far lower compared to simply sticking to the basics of 3 out of 3. This guarantees users that their data is safe and retrievable when they want it.

All data is encrypted and only the user has the decryption key

All clients’ data is encrypted before getting stored in the host’s drive. This implies that no one can know the details of the stored file. Even in the event that the files are accessed by a third party, it will be impossible to access them without the decryption key. Only the user has the key. The user accounts and their personal information is also encrypted such that even the miners who confirm transactions can only follow back to know the balance in the accounts.

Siacoin development team is always on the lookout for gaps

Because of the stiff competition in the industry, the Siacoin development team is always on the lookout for gaps and bugs targeted at its system. The team also follows the developments in other networks to protect users from emerging risks.

As the Siacoin development team works tirelessly to keep the data and users safer, it is important that the nodes also do their part. Whether you are a host, user, investor, or miner in the Siacoin system, the following five points are very important.

  • Ensure that your computer and system are protected by good anti-malware software.
  • Make sure to avoid visiting risky sites that can give attackers easy access to your Siacoin account.
  • The private keys and the recovery seed phrase should be stored safely and away from the main computers. Also, they should never be shared with third parties.
  • If you opt to trade Siacoin in the markets, it is important to know that they are the easiest target for hackers. Therefore, make sure to use the exchanges that have good security features and move the SC to a cold storage when not trading them.
  • Always triple check the public address of the person you are paying in Siacoin to avoid sending to the wrong address because it implies permanent loss.

Examples of Siacoin’s use cases / applications.

Though Vorick David and Luke Champine had a very clear goal of how they wanted Siacoin to be used, its applications have increased over time. Here are the main Siacoin applications.

  • People with extra drive space in their computers can rent it to those who want it for a fee. Some investors are even focusing on acquiring larger drive space and lending it to Siacoin users for extra pay.
  • Users who have a lot of data to store but do not want to maintain their own systems can reach Siacoin to rent space. Since the storage cost is lower compared to top data providers, Siacoin is a great option for heavy data users especially those working on projects for short time-frames that do not warrant installing own storage systems.
  • Siacoin is one of the high potential cryptocurrencies in the market. This has made it a great investment option. You can opt to trade Siacoin in the market or hold the coins waiting for the price to grow. Note that such holding is based on speculation.
  • You can use Siacoin to pay for products and services in the stores that accept it. This could be e-commerce stores or conventional markets.
  • As a cryptocurrency listed in most markets, you can opt to use it to pay for transaction fees. This is especially useful when operating as cryptocurrency only exchanges.

Bytecoin

What is Bytecoin?

Bytecoin is an untraceable cryptocurrency that utilizes CryptoNote ring signatures to make transactions completely anonymous. Like Bitcoin, Bytecoin is mainly aimed at facilitating peer2peer payments. This means that it shares most use cases with Bitcoin.

The cryptocurrency was created back in 2012, but little was known of its founders by then because they opted to operate completely anonymous. However, they started opening up around 2016 by communicating via multiple channels. Bytecoin also has a very close history with one of its forks, Monero.

What is the problem that Bytecoin Solves?

Since 2009 when Bitcoin was developed and released, corporate entities and even the general public have appreciated that digital cash can be simple yet highly convenient for making payments just like notes and credit cards. However, Bitcoin simply opened the lid to the new technology. A few years after establishment, the Bitcoin system has manifested great inflexibility that prevents improvement with new features. For example, unless all new users update their clients, it is impossible to implement new features. In many cases where these flaws cannot be rectified, the option is crafting a completely new project. This is the case with Bytecoin. Here are the main problems that Bytecoin seeks to solve.

  • Transaction traceability: The Bytecoin development team created a test that focused on two core components; traceability and linkability. Because transactions at Bitcoin take place in public, it is possible to trace them to the source and recipient ambiguously. An engineered path can still be used to pull the origin and final recipient.
  • The proof of work function: Satoshi Nakamoto, the Bitcoin creator, pointed out that the majority decision-making consensus more was “one node one vote.” The security of this model suffers huge setbacks because 51% of the network mining power has to be under the control of honest Bitcoin users. Besides, even minor fixes such as bugs and gaps still require 51% mining power.
  • Irregular emission: Bitcoin system relies on a predetermined emission rate. Every solved block releases a specific (fixed) number of coins that halves every four years. Now, what will happen when the breaking point is reached? Though the shift from 12.5 Bitcoins at the start might not seem much in the subsequent 4 years, what about in the subsequent lapses every 4 years?
  • Hard coded constants: Bitcoin has a lot of hard-coded limits with some of the natural elements being original designs while others have proven to be artificial constraints. They also act as a point of centralization. Even with the peer2peer outlook of Bitcoin, most nodes utilize official reference client designed by a few users. When this group makes the decision to add changes, many nodes simply accept. It was a source of heated debate at some point with the others even calling for a boycott.
  • Bulky scripts: The model of scripting system employed at Bitcoin is very heavy and indeed complex. Users are allowed to come up with sophisticated transactions, though some features are disabled because of security fears. For example, the common script for sender and receiver is 164 bytes long though the purpose is very simple; checking if the receiver has the right key for signature verification. Take a look at the example given below.

<sig> <pubKey> OP DUP OP HASH160 <pubKeyHash> OP EQUALVERIFY OP CHECKSIG.

How does Bytecoin Solve the problem?

a) One-time ring signatures

The standard protocol based on one-ring signature only allows users to achieve unconditional unlinkability. Bytecoin utilizes CryptoNote to keep transactions unlinkable and untraceable. The transactions utilize a one-time public key when there are multiple transactions with the same client. This helps to address the issue of addresses re-use and traceability.

One time ring signatures further help to mix your signature with others in the network to make it completely unlinkable. Besides, you are completely in control of the ring signature’s anonymity. By adding more input, the transactions become more obscure. However, the associated transactions will be higher. Have a look at the ring signatures CryptoNote keys.

b) The Egalitarian Proof of Work

The Bitcoin’s PoW consensus algorithm system strongly favors those with powerful ASIC and GPU miners compared to others using CPUs. This has resulted in centralization around those with powerful machines. To address this problem, Bytecoin closes the gap through the adoption of the Egalitarian proof-of-Work consensus model.

The Egalitarian PoW utilizes skrypt, which is a special function that closely resembles hashcash function used in Bitcoin. The primary difference between the two is that Skrypt is not memory bound. This implies that you can easily create standard CPU mining rigs that are highly effective. The Skrypt model further helps in balancing power dynamics since GPUs are linearly better compared to CPUs.

c) Smooth coin emission

Because of the halving of Bitcoin mining rewards, the miners are heavily demotivated resulting in a sharp decline in hashrate every 4 years. The lower hashrate implies that the network gets more susceptible to double-spend. To address the issue, Bytecoin decreased the block reward with every block. This provides for a smoother decrease in rewards over time compared to that of Bitcoin. The reward at Bytecoin adopts the following equation.

BaseReward = (MSupply – A) / 218

Where MSupply is equal to (2^64) – 1 atomic units,

What makes Bytecoin better than it’s competitors?

With the cryptocurrency niche advancing at a very fast rate, the niche has become very competitive. Here are some of the main reasons for making Bytecoin better than its competitors.

  • Bytecoin adjusts the mining difficulty after every block. This makes it better than Bitcoin Cash and Bitcoin that adjusts mining difficulty after 2016 blocks are mined. By adjusting the mining difficulty after every block, it becomes difficult for miners to use a multiplier effect once a difficulty has been established.
  • Bytecoin makes it easy for more people to join and use the network. By adopting an Egalitarian PoW that utilizes skrypt, it means that miners cannot take advantage of advanced ASICs to optimize mining.
  • It operates as a truly decentralized platform. By drifting away from the standard PoW used at Bitcoin, it implies that more users can now join and mine Bytecoins using their PCs. The model further helps to reduce the risk of 51% attack.
  • Bytecoin penalizes miners who target staffing a block above his transaction that attracts zero fees. Though only a few miners have this ability, it is still possible resulting to bloating of the network. This is a major problem for many Bytecoin competitors. To address the issue, Bytecoin introduced a penalty function where miners can only create the usual block size and pay a penalty hen the size is surpassed.
  • The transaction scripts are very minimalistic at Bytecoin. This is a great departure from the model employed especially by Bitcoin and Bitcoin Cash. This makes it easy to implement new features and progressively improve the network.
  • Bytecoin is attracting a lot of people because of its anonymity that makes discovery by a third party or third party seizures very difficult. This is very important at a time when most administrations have vowed to pass harsh regulations to crack on cryptocurrencies.
  • Bytecoin is way cheaper to send payments compared to Bitcoin Cash or even Ethereum among others. With one of the primary goals of going crypto being to cut on transaction charges, Bytecoin allows users to send Bytecoins for free and handles all scaling issues in a great way. However, using a network such as Bitcoin to send funds is very expensive.
  • Using Bytecoin to send transactions is really fast. Bitcoin, even with SegWit technology is still very slow to settle a purchase. This implies that many people especially traders prefer Bytecoin to Bitcoins because clients can make payments and get cleared immediately.
  • Having been in the market for some time, Bytecoin is considered stable because most of its features are tested and proven to work. This makes a lot of people in the crypto world prefer it to newer competitors that are only entering the market. In most of the cases, a time span of about five years or more is needed before a cryptocurrency network is proven stable and reliable.

How can Bytecoin be categorized?

Bytecoin is a truly anonymous and decentralized cryptocurrency with the potential to become the next Bitcoin. Its design is derived from Bitcoin while the focus ensured that most of the issues reported at Bitcoin were addressed. In different terms, Bytecoin is another improved version of Bitcoin. From transaction anonymity to security, every aspect of Bytecoin is better compared to what users get at Bitcoin or Bitcoin Cash among other networks.

But it is the ability of Bytecoin to address the issue of centralization that has made it win a place in the heart of the crypto community. The Proof of Work consensus algorithm used at Bitcoin drove away many small users leaving the pioneer cryptocurrency in the hands of a few people who could afford the expensive mining ASICs. Now, Bytecoin has helped to completely decentralize the system so that more people including those with CPUs can still mine and contribute to consensus building.

What’s Bytecoin’s vision on Security?

Bytecoin’s vision is to provide users a completely anonymous and secure network that they can use without worrying of losing their assets or discovery by third parties. Bytecoin achieves this in bits by helping to protect users from linkability through CryptoNote.

Bytecoin code is also strengthened to ensure that their signatures remain secure and impossible to forge. This implies that once you join the Bytecoin network, you can work without worrying about your account getting attacked.

Note that even as Bytecoin forges on with its security dream, users are also expected to do their part. It is important to ensure that you keep the computer and client updated all the time to avoid attackers utilizing gaps in old software. Other efforts recommended by Bytecoin to its users include:

  • Keeping your private keys as secret as possible.
  • Backing up your information at Bytecoin.
  • Triple checking the public keys before sending value all the time.
  • Trading Bytecoins only on the secure exchanges.
  • Moving the Bytecoins to cold storage when not in use.
  • Staying away from risky sites if multitasking on the computer used to access Bytecoin network.

Examples of Bytecoin’s use cases / applications?

Many applications of Bytecoin are derived from its ability to keep its users completely anonymous. Here are some of them.

  • Most people prefer Bytecoin to save their funds because it is untraceable and they cannot be easily discovered. Whether it is family wealth, company resources or other forms of cash, it becomes untraceable the moment you buy Bytecoins.
  • As an anonymous network, Bytecoin is a great option for purchasing products that you do not want to be traced back to you. This is the reason why businesses dealing with products that are not approved by governments are finding solace in Bytecoin.
  • Gambling. Many gambling sites around the globe are allowing their clients to make payments in cryptocurrencies. This is seen as a new method of increasing their customer base and diversifying the payment portfolio.
  • Paying for goods and services in stores that accept Bytecoin. Unlike in 2009 when very few people knew about cryptocurrencies, the popularity has grown so much. Now, more stores are opening their doors to allow those with cryptocurrencies such as Bytecoin to make direct payments. Bytecoin is emerging as a preferred option because it is cheaper and transactions clear faster.
  • Use Bytecoins to pay transaction fees at the exchanges. For people who prefer to trade Bytecoins in the markets, the coins can be used to pay for the transaction fees. Some of the exchanges that list Bytecoin include Poloniex, Bittrex, and Bithumb.
  • Bytecoins can be used as a method of enhancing your income. You can do this by trading Bytecoins against other cryptocurrencies such as Ripple and NTX in the markets. The markets operate the same way forex platforms work but deal with cryptocurrencies such as Bytecoins.
  • Use Bytecoin to pay taxes. If you live in a state such as Arizona that allows users to pay taxes in cryptocurrencies, you can clear taxes in Bytecoin. In such cases, the Bytecoins are converted to USD immediately after payment and credited to your account.
