Solana

14/09/21
1,825Live transactions per second, $0.00025 Avg. cost per transaction, 975 Validator nodes. "Solana is the fastest blockchain in the world and the fastest growing ecosystem in crypto, with over 400 projects spanning DeFi, NFTs, Web3 and more." Developed with Rust Programming Language, great documenation, API and programmers support. Vaildators can run by anyone, but You must stake own capital and go through certification for efficiency. Experience of authors in Real Time systems can result in high transaction processing rate, but can we trust that this is really independent network of nodes if somebody must decide to join You node to it? Is this really cryptocurrency ecosystem or just technical framework?

Stellar

18/09/21
cryptocurrency ecosystem oriented on sending money value fast and cheap between different countries and fiat integration. Concept of Anchors can provide local exchanges, anyone can be a local Anchor in his country. Anchors Connect Stellar to the Traditional Banking System. Users can also issue own tokens, validations nodes can be set up but without rewards and staking. Strong business and social goals - to promote using Stellar for easy and low cost remittances. XLM Lumens is native coin. Stellar is hoping to build something as powerful but more user-friendly and more compatible with the existing monetary system.

Polygon

01/11/21
"Polygon is a protocol and a framework for building and connecting Ethereum-compatible blockchain networks. Aggregating scalable solutions on Ethereum supporting a multi-chain Ethereum ecosystem.". "Polygon combines the best of Ethereum and sovereign blockchains into a full-fledged multi-chain system. Polygon solves pain points associated with Blockchains, like high gas fees and slow speeds, without sacrificing on security. This multi-chain system is akin to other ones such as Polkadot, Cosmos, Avalanche etc, but with at least three major upsides: It is able to fully benefit from Ethereum’s network effects It is inherently more secure It is more open and powerful"

Tezos

20/12/21
"Tezos is an open-source platform that addresses key barriers facing blockchain adoption for assets and applications backed by a global community of validators, researchers, and builders. By design, Tezos embraces long-term upgradability, open participation, collaboration, and smart contract safety." Based on Ethereum concepts, but not Pow. More progressive, but less popular. It needs a fire test, but has a chance to be at the top.

Algorand

21/12/21
"With more than 500 global organizations leveraging its technology, Algorand is enabling the simple creation of next generation financial products, protocols and exchange of value across defi, financial institutions and governments." Algorand is a wide cryptoplatform project, with plenty of University and others supporters. New governance rules give more democracy,trust and user engagement to its PoS and rewards (instead of PoW mining). Support for Smart Contracts, NFTs, Open Source with Algorand Fundation above... Really this Ethernet successor? What about scalability and performance? True Independency? So many question. But You can setup Your own node easily, this is always good sign.

XRP Ledger

The XRP Ledger (XRPL) decentralized public blockchain homepage. Links to XRP Ledger Documentation, XRPL Use Cases, History, Ledger Explorer, XRP Overview, Carbon Calculator, About, XRPL Foundation. Community links. "XRPL uses a consensus protocol, in which designated servers called validators come to an agreement on the order and outcome of XRP transactions every 3-5 seconds." "Unlike most other blockchains, the XRP Ledger does not need mining, so no energy is wasted in the transaction process. Learn how this compares to other platforms with our Green Currency Calculator. "
