The elephant in the blockchain room

Are you excited about blockchain's future? Wait, but what about the elephant in the room - scalability? Are you someone who can`t wait to see a new blockchain claiming millions of transactions per second to invest in it? Credits will solve it? Doubt it. Credits lack security, and they have shown it many times.

It is incredibly hard to build a secure, decentralized and scalable blockchain and make no mistake - most of those projects claiming millions of TPS will fail, most likely because of the secutiry. Now we have EOS, Cardano upcoming. EOS is practical but it has decentralization issues having only 21 masternode validators. Cardano is cool, but it is going to take some time to get it up-and-running and it is very complex(many failure points).

The problem of decentralization/scalability/security is best ilustrated like that:

I am very thrilled to present to you QuarkChain. Now, since I am not a technical person I will not delve in the details, but give you links to read more if you like.

What is QuarkChain and what are the features?

• Shardable two-layered blockchain. Unlike Ethereum, where it will take years to implement sharding, in QuarkChain it is by design. Shard`s transactions are confirmed in the root chain

• Guaranteed security by market- driven collaborative mining-basically, to ensure the security of all transactions at least 50% of the overall hash power is allocated to the root blockchain preventing double spending attacks.

• Anti-centralized horizontal scalability- Quarkchain allows multiple small nodes form a cluster to replace a super full node. This helps the system become more decentralized

• Simple account management- only 1 account needed for the all the blockchains(shards) in Quarkchain. All cryptocurrencies from different shards are stored in one smart wallet. A user will be able to manage all addresses in all shards via a single private key.

• EVM - Quarkchain will support ethereum smart contracts.

The team behind QuarkChain is very serious and will get the job done. I have heard from many sources that their tech is the real deal, including the guys from Hashed - the biggest blockchain fund in the world!

For more details please read the whitepaper. It is an incredibly read and I will read it a few more time just for fun.

My personal opinion is that QuarkChain is an incredible position to be the first blockchain which is really scalable, decentralized and secure in the same time. Given that, I think that it has the potential to even surpass Ethereum in a few years, we will see!
