What is Proof of Work (PoW)??

Proof of Work is the original consensus mechanism that powers Bitcoin and many other cryptocurrencies. It relies on miners competing to solve complex mathematical puzzles, which secures the network and validates transactions. This ensures the blockchain is decentralized, tamper-proof, and highly secure, though it requires significant computational power.

Different cryptocurrencies use various mining algorithms—such as SHA-256 for Bitcoin or Scrypt for Litecoin—to suit their unique needs. These algorithms determine how mining works and what kind of hardware is needed, showcasing the flexibility of PoW technology.

Bitcoin

Bitcoin is a Proof of Work (PoW) cryptocurrency that uses the SHA-256 algorithm to secure its transactions. Created in 2009 by an anonymous developer known as Satoshi Nakamoto, it is the first and most popular cryptocurrency, widely recognized as the foundation of the entire crypto industry.

Litecoin

Litecoin operates as a Proof of Work (PoW) cryptocurrency using the Scrypt algorithm for transaction security. It was launched in 2011 by Charlie Lee and has gained popularity as a faster, more lightweight alternative to Bitcoin.

Kaspa

Kaspa is a Proof of Work (PoW) cryptocurrency that uses the kHeavyHash algorithm to secure its transactions. Launched in 2021, it is designed for fast and scalable block processing, making it popular among miners and developers seeking an efficient PoW blockchain.

Ethereum Classic

Ethereum Classic is a Proof of Work (PoW) cryptocurrency that employs the Etchash algorithm to secure its blockchain. Launched in 2016 after a split from Ethereum, it remains a popular choice for those adhering to the original principles of Ethereum’s blockchain.

ZCash

Zcash operates as a Proof of Work (PoW) cryptocurrency using the Equihash algorithm for secure and private transactions. Created in 2016, it is popular for offering users the choice between transparent and shielded transactions.

Siacoin

Siacoin is a Proof of Work (PoW) cryptocurrency that utilizes the Blake2b algorithm to secure its blockchain. Launched in 2015, it powers the Sia decentralized cloud storage network, gaining popularity for enabling affordable and secure file storage.

Dash Coin

Dash is a Proof of Work (PoW) cryptocurrency that uses the X11 algorithm to secure its transactions. Created in 2014 as a fork of Bitcoin, it is popular for its focus on fast and private payments, making it a widely used digital currency for everyday transactions.

Monero

Monero is a privacy-focused Proof of Work (PoW) cryptocurrency that uses the RandomX algorithm to secure transactions and maintain anonymity. Launched in 2014, it is one of the most popular privacy coins in the crypto space.

CKB (Nervos Token)

Nervos operates as a Proof of Work (PoW) cryptocurrency that uses the Eaglesong algorithm to secure its transactions. Introduced in 2019, it is known for its unique layered architecture, allowing interoperability and the development of decentralized applications (dApps).

Handshake

Handshake is a Proof of Work (PoW) cryptocurrency that employs the Blake2b + SHA3 algorithm to secure its blockchain. Launched in 2020, it focuses on decentralized domain name systems (DNS), gaining traction as a tool for improving online security and privacy.

SCPrime

SCPrime is a Proof of Work (PoW) cryptocurrency that uses the Blake2b algorithm to secure its blockchain. Launched in 2018, it powers a decentralized cloud storage network, focusing on reliability and scalability for enterprise-level data storage solutions.
