Blockchain is the most scalable and user-centric tech ever.

Hello guys!

I wanted to share with you some thoughts regarding scalability and user-centricity about decentralized technologies, and why a decentralized approach cannot be beaten by a centralized one. We used to hear that these technologies are not (yet) scalable enough; nor user-centric. And it is true from one viewpoint. I would like to share my viewtpoint from another angle that I find elegant and beautiful.

Centralized applications are not user-centric. Even if they have great user experience, the global experience is poor : Fintech are focused on one value proposition. And you need one account for each application. So if you want to trade stocks for free, manage your payments easily, invest your spare change, do some online shopping, or place some bet on your favourite football team, you need as many account and as many application as the number of things you want to do. And beceause these centralized cannot be interoperable, you cannot access buy stocks listed on Robinhood from your Coinbase wallet; neither place a bet on Betclick from your revolut account; nor lend on Zopa what you have saved on Acorns...

So, some applications like Revolut tries to aggregate several services to capture market shares: they copied Acorns, Robinhood, so now you will be able to buy crypto (CFD) and stocks for free, trade Fx for free soon also, invest your spare change, and there also develop a myriad of services such as insurance.

Centralized applications are not scalable. If you want to add a service or value proposition to Revolut, you cannot. And it will take years for Revolut to be able to aggregate different services that its competitor are providing. There is no collaboration, but only competition, in the centralized world.

Decentralized technologies allow us to build everything around the user account. So you do not need to have one app aggregating all the value. Actually, it fosters a collaborative genius: people can create their Dapps, and you can access them seamlessly from your wallet. This is the value proposition of Web3 Browser such as Trust Wallet, Coinbase Wallet (ex Toshi), Status, Cipher etc. Therefore, it allows the ultimate level of user-centricity. Everything is accessible and built around the users wallet. No need to move your funds, no need for several accounts.

Therefore, they are ultra scalable! Since you can access to unlimited number of Dapps, and since the number Dapps is growing day after day, each day you can potentially add 10 more new services or value proposition to your wallet. Dapps like MultiToken allows you to create/invest in ETF-like crypto asset. Tottle allow you to build a portfolio in few second. You can access to poker, to casino, you can even dream of derivatives such as options, made only of smartcontracts, so you could protect yourself from market moves.

This is why decentralization is beautiful. Yet, a lot of challenges remain! the "real" scalability issue (regarding tps, and computing resources) and interoperability; but we do not need a full decentralized world; the semi-decentralized approach is maybe the good one!
