IOTA is a transactional settlement protocol that enables you to transact sub-cent values Peer-to-Peer without any transaction fees for either the sender or the recipient. A move away from blockchain, IOTA’s distributed ledger, by contrast, does not consist of transactions grouped into blocks and stored in sequential chains, but as a stream of individual transactions entangled together. In order to make a transaction in the Tangle, two previous transactions must be validated with the reward for doing so being the validation of your own transaction by some subsequent transaction. With this ‘pay-it-forward’ system of validations, there is no need to offer financial rewards. Transacting with IOTA is fee-free.

At its core, the Tangle still has the same underlying principles as a Blockchain: it’s still a distributed database, it’s still a P2P Network and it still relies on a consensus and validation mechanism. Similar to bitcoin, Iota’s network’s security is derived from the strength of its numbers. Hence, the more the number of nodes within IOTA’s tangle, the more secure it is against attacks.

EOS

EOS is smart contract platform that attempts to solve the problem of speed, scalability, and flexibility that often become a bottleneck for blockchain-based systems. It is a blockchain-based, decentralized system that enables the development, hosting, and execution of commercial-scale decentralized applications (dApps) on its platform.

EOSIO is software designed to enable vertical and horizontal scaling of decentralized applications. This is achieved through an operating system-like construct upon which applications can be built. The software provides accounts, authentication, databases, asynchronous communication and the scheduling of applications across multiple CPU cores and/or clusters. EOS has the potential to scale to millions of transactions per second, eliminates user fees and allows for quick and easy deployment of decentralized applications.

ZCash–

Zcash is an implementation of the Decentralized Anonymous Payment scheme Zerocash, with security xes and adjustments to terminology, functionality and performance. It bridges the existing transparent payment scheme used by Bitcoin with a shielded payment scheme secured by zero- knowledge succinct non-interactive arguments of knowledge (zk-SNARKs). It attempts to address the problem of mining centralization by use of the Equih
