Bitcoin (BTC)

The original cryptocurrency and digital gold standard. Bitcoin pioneered blockchain technology and remains the most secure and widely adopted cryptocurrency. It operates on a proof-of-work consensus mechanism and has a fixed supply of 21 million coins. Bitcoin serves as a store of value and digital currency for peer-to-peer transactions worldwide.

Bitcoin Cash (BCH)

A Bitcoin fork created in 2017 to improve transaction speed and reduce fees. Bitcoin Cash increased the block size limit to allow more transactions per block, making it more suitable for everyday payments. It maintains Bitcoin's core principles while focusing on scalability and lower transaction costs. BCH aims to be digital cash for the world.

Fractal Bitcoin (FB)

Fractal Bitcoin is a cryptocurrency that enhances the scalability of the Bitcoin network through a recursive sidechain architecture. By utilizing the Bitcoin Core code, it creates multiple layers on top of the Bitcoin blockchain, allowing for significantly higher transaction throughput and faster confirmation times of 30 seconds or less. As a merge-mined cryptocurrency, Fractal Bitcoin leverages the same mining process as Bitcoin, ensuring robust security and decentralization. Its goal is to facilitate the development of large-scale applications directly on the Bitcoin blockchain, thereby expanding its utility and potential for mass adoption.

Bitcoin SV (BSV)

Bitcoin Satoshi Vision emerged from a Bitcoin Cash fork, aiming to restore Bitcoin's original protocol. BSV features massive block sizes to enable high transaction throughput and low fees. It focuses on enterprise applications, data storage, and smart contracts while maintaining Bitcoin's proof-of-work security model. BSV positions itself as the true vision of Satoshi Nakamoto.

ACOIN

A SHA-256 based cryptocurrency that focuses on accessibility and community-driven development. ACOIN utilizes Bitcoin's proven mining algorithm while implementing features designed for everyday use. The project emphasizes fair distribution, sustainable mining practices, and building a strong community ecosystem. It aims to bridge traditional finance with blockchain technology.

Curecoin (CURE)

A unique cryptocurrency that combines blockchain mining with protein folding research for medical breakthroughs. Curecoin rewards miners for contributing computational power to Stanford University's Folding@home project, which helps research diseases like cancer and Alzheimer's. This innovative approach makes mining productive for humanity while maintaining network security through traditional SHA-256 mining.

eMark (DEM)

A German-originated cryptocurrency designed for practical digital payments and micropayments. eMark features fast transaction confirmations and low fees, making it suitable for everyday commerce. The project focuses on European markets and aims to provide a stable, reliable digital currency alternative. DEM emphasizes simplicity and user-friendly adoption for mainstream use.

Joulecoin (XJO)

Joulecoin (XJO) is a cryptocurrency that features quick confirmations and transaction comments, utilizing a customized version of Bitcoin's core technology with lowered block time for higher performance and a long proof-of-work period. It does not focus on energy efficiency or renewable energy usage.

Peercoin (PPC)

The first cryptocurrency to implement proof-of-stake consensus alongside proof-of-work. Peercoin pioneered the concept of minting coins through stake ownership, reducing energy consumption compared to pure mining systems. It features a unique approach to network security and coin distribution, combining the best of both consensus mechanisms. PPC is designed to be more sustainable and energy-efficient long-term.

Terracoin (TRC)

A Bitcoin-based cryptocurrency designed for stability and long-term value preservation. Terracoin implements enhanced security features and focuses on being a reliable store of value and medium of exchange. The project emphasizes steady development, community governance, and practical applications for digital commerce. TRC aims to provide a dependable alternative to traditional fiat currencies.

Unbreakable (UNB)

A security-focused cryptocurrency that emphasizes robust network protection and resistance to attacks. Unbreakable implements advanced cryptographic techniques and multiple security layers to ensure transaction integrity and network stability. The project prioritizes building an impenetrable blockchain infrastructure that can withstand various forms of digital threats. UNB represents the next generation of ultra-secure digital currencies.
