SC price can be volatile. You can see the history of price changes in the cryptocurrency price chart below to help you make the best decision while considering buying crypto.

Siacoin (SC) is a cryptocurrency that operates on the Sia network, a decentralized cloud storage platform. Sia aims to revolutionize the way data storage is done by utilizing blockchain technology and peer-to-peer networks. The platform enables individuals and businesses to rent out their unused hard drive space in exchange for Siacoins or to utilize the network for storing their data. By splitting and encrypting data into multiple pieces and distributing them across the network, Sia ensures data redundancy, privacy, and security.

Siacoin was founded by David Vorick and Luke Champine. They developed the Sia network and launched Siacoin in 2015. The primary motivation behind creating Siacoin and the Sia network was to address the limitations and inefficiencies of traditional cloud storage systems.

David Vorick and Luke Champine recognized the centralized nature of existing cloud storage services and the potential risks associated with relying on a single provider for data storage. They aimed to create a decentralized, secure, and cost-effective alternative that leverages blockchain technology.

The Sia network allows individuals and businesses to rent out their unused hard drive space, creating a distributed network of storage providers. 

The founders envisioned a future where users could have full control over their data, without relying on a single centralized authority. Siacoin serves as the native cryptocurrency of the Sia network, facilitating transactions and incentivizing participants to contribute their storage resources.

Siacoin serves as the native cryptocurrency of the Sia network and is used for various purposes within the ecosystem. Users can pay for storage services on the Sia network using Siacoins, and hosts are rewarded with Siacoins for providing storage space. The decentralized nature of Sia ensures data security, privacy, and redundancy, as files are split into multiple pieces, encrypted, and stored across the network.

Siacoin operates on its own blockchain and employs a proof-of-work (PoW) consensus mechanism called "Blake2b." This mining algorithm allows users to mine Siacoins by contributing computational power to secure the network and validate transactions.

The Siacoin ecosystem revolves around the Sia network and its decentralized cloud storage platform. The ecosystem consists of various components and participants that contribute to its functioning.

The Sia network is the underlying infrastructure that enables decentralized cloud storage. It consists of a peer-to-peer network of hosts who rent out their unused hard drive space and clients who store their data on the network.

Sia-UI is the official user interface for the Sia network. It provides a graphical interface that allows users to interact with the network, manage their storage contracts, and upload or download files. Sia-UI also includes a wallet for storing and managing Siacoins.

Hosts are individuals or businesses that offer their hard drive space to the Sia network. They earn Siacoins by renting out their storage capacity to clients. Hosts must meet certain requirements, such as maintaining uptime and meeting performance standards, to participate in the network.

Clients are users who utilize the Sia network for storing their data. They pay hosts in Siacoins for the storage space they consume. Clients benefit from the decentralized and redundant nature of the network, which enhances data security and privacy.

When a client wants to store data on the Sia network, they create a file contract with a host. The contract specifies the terms of storage, including duration, price, and redundancy level. The contract is enforced by smart contracts on the Sia blockchain, ensuring that both parties adhere to the agreed-upon terms.

In addition to Siacoins, the Sia network also includes a separate cryptocurrency called Siafunds. Siafunds represent a proportional claim to a portion of the revenue generated by storage contracts on the network. Siafunds are held by the Sia team and can be used to fund the development and support of the ecosystem.

Siacoin is designed as a utility token primarily used for transactional purposes through smart contracts. Unlike some other cryptocurrencies, Siacoin does not have a maximum supply. The rationale behind this decision is to align with the virtually limitless potential for data creation and storage on the Sia network.

As of May 2023, the circulating supply of Siacoin is 54,143,962,991 SC.

New Siacoins are introduced into circulation as mining rewards through the Sia blockchain's proof-of-work mining algorithm. Initially, the mining reward was set at 300,000 SC per block and gradually decreased by 1 SC with each successfully mined block. This reduction continued until July 2020 when the block reward reached a fixed amount of 30,000 SC. Moving forward, the block reward will permanently remain at this level.

Within the Siacoin ecosystem, tokens are removed from circulation in certain situations. For instance, when hosts engage in malicious behavior or fail to refund collateral, they may lose tokens. Additionally, the development team plans to introduce a proof-of-burn mechanism in the future. This mechanism will require hosts to burn a small portion of their revenue, serving as a validation of their authenticity and positive intentions.

By ensuring a continuous supply of Siacoins and implementing measures to discourage harmful actions, the Siacoin ecosystem aims to facilitate secure and efficient transactions within the Sia network while supporting its decentralized cloud storage infrastructure.

Siacoin (SC) can be purchased on various cryptocurrency exchanges, including Binance, Bittrex, Huobi Global, Upbit, OKEx, etc. You can also buy SC at SwapSpace, right on this page.
