Bitcoin is a decentralized digital currency without a central bank or single administrator. It can be sent from user to user on the peer-to-peer bitcoin network without the need for intermediaries. Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. The cryptocurrency was invented in 2008 by an unknown person or group of people using the name Satoshi Nakamoto. Its implementation was released as open-source software in 2009 and began to be used then.

Ethereum is the first decentralized, open-source blockchain with smart contract functionality. It was initially described in a white paper by Vitalik Buterin in late 2013 and launched in 2015. This network serves as the foundation for an ecosystem of interoperable, decentralized applications (dApps) powered by token economies and automated smart contracts. Assets and applications designed on Ethereum are built with self-executing smart contracts that eliminate the need for a central authority or intermediary. 
The network is powered by its native cryptocurrency ether (ETH), which is used to pay transaction fees. Ethereum has the characteristics of being open-source, programmable, private, and censorship-resistant, forming the backbone of a decentralized internet.

Shiba Inu is a decentralized meme token that has evolved into a vibrant ecosystem.

Hedera is designed for fast, fair, and secure applications to take advantage of the efficiency of Hashgraph on a decentralized, public network that can be trusted. By limiting the number of nodes involved in key functions such as timestamping and transaction ordering, Hedera Hashgraph is able to quickly achieve finality, reducing the possibility that changes to the state of transactions might be made later.

Bitcoin Cash is a cryptocurrency that intends to provide an alternative to Bitcoin. Launched in 2017, Bitcoin Cash was created by a group of Bitcoin users who disagreed with the roadmap proposed by the project's principal developer group, Bitcoin Core, and believed that different technical decisions were necessary to make Bitcoin available to a global audience.

TON (The Open Network) is a fully decentralized Layer-1 blockchain designed by Telegram. It offers ultra-fast transactions, minimal fees, easy-to-use apps, and is eco-friendly.

Polkadot is a cross-chain protocol designed to connect and secure different blockchains. It provides interconnectivity and interoperability between them, enabling independent chains to securely exchange messages and perform transactions without relying on a trusted third-party. This allows for cross-chain transfers of data or assets between different blockchains, as well as the development of cross-chain DApps (decentralized applications) using the Polkadot Network. The Web3 Foundation is responsible for building Polkadot.

Litecoin is a peer-to-peer digital currency for online payments. It is a global payment network that is fully decentralized, without any central authorities.
