All through this collection of articles, we’re trying on the prime blockchains in crypto that will help you make sense of the alphabet soup of so-called “altcoins” that exists past that of Bitcoin’s BTC and Ethereum’s ETH.
We are going to take a look at what they’re, how they work, what they do, and their professionals and cons.
You’ll come out of this collection not solely with a greater sense of what cryptocurrency is all about, however you’ll additionally perceive why the best way a token works — the best way its blockchain processes transactions — is essential to its success or failure as a digital asset.

So, what’s Cosmos?
Effectively, it’s an “Web of blockchains” if you happen to ask its builders.
What does that imply? Merely put, Cosmos’ largest objective is to create an ecosystem of interoperable blockchains that may talk, share information and transact with one another.
Like the remainder of the “Ethereum killers,” Cosmos is a proof-of-stake blockchain that doesn’t use the large quantity of pollution-generating electrical energy that Bitcoin and Ethereum do.

And like them, it presents itself as a quicker and extra scalable, environmentally pleasant and extra interoperable various to Ethereum. Cosmos can course of 10,000 transactions per second, or TPS, in comparison with Ethereum’s 15-25 TPS. It has a block time of round one second.
However that’s not the one pace Cosmos is interested by. A key function is that every decentralized app can construct its personal blockchain — known as a “zone”— quite than share one. That makes them quicker and cheaper to construct.
Cosmos has an open-source software program growth package (SDK) that makes use of the Tendermint engine consensus protocol by default however others can be found. Utilizing the SDK makes the method of constructing a zone far easier because it gives what’s described as a blockchain-in-a-box. This leaves DApp builders free to focus on constructing the applying for their very own blockchain zone.
The zones are linked by way of hubs. The principle one is the Cosmos Hub, however others can be found. However any zone or hub can refuse to work with one other. They communicated via the Inter-Blockchain Communication, or IBC, protocol, which permits them to work together.
Past that, Cosmos hubs may also hook up with different blockchains resembling Bitcoin and Ethereum. Among the many developments fueling Cosmos’ robust latest outcomes is an upcoming bridge to Polkadot.
Not Just like the Relaxation
On the Cosmos Hub, the highest 100 validators — these with probably the most ATOM tokens staked — are chosen to validate a transaction. As delegators can stake tokens and earn rewards by becoming a member of a validator’s pool, this could change at any time. Nonetheless, every zone can create its personal cryptocurrency quite than use ATOM. Every zone can select its personal hub, which supplies entry to different validation methods and validator units. This implies non-public, permissioned blockchain zones could be created together with public ones, and even switch tokens between them.
As a result of every DApp has its personal zone/blockchain, it has sovereignty over its personal atmosphere — and doesn’t have to regulate to the wants of different DApps on a shared blockchain.
This may increasingly sound like Polkadot’s 100-parachain construction, however it differs in a number of vital methods. All of Polkadot’s parachains share the identical set of validators.
Whereas Polkadot permits customers to instantly entry a wise contract on a distinct parachain, and switch tokens from one parachain to a different, Cosmos’ IBC focuses on asset transfers between chains. If two zones wish to work together, Zone A and Zone B relay messages by way of IBC via the Cosmos Hub. That approach, a file of every transaction is saved in three locations — the 2 zones and the Hub.
Nor does Cosmos divide the blockchain into a number of components like Cardano and Avalanche, which pace up their blockchains by separating the smart-contract layer the place the precise exercise of the DApps takes place from a transaction layer which sends solely the outcomes of the transaction onto the blockchain and the networking layer. Utilizing Tendermint merely gives the transaction and networking perform of every blockchain — the “zone” — as a prebuilt module, saving growth time and requiring much less experience.
