Two Weeks of Solana, here a look into my week !

I’m now 14 days into #100DaysOfSolana, and looking back at the first two weeks, I realize how much my understanding of Solana has changed.

When I started, I mostly thought of a wallet as a place where you keep cryptocurrency. Now I understand that a wallet is built around a cryptographic keypair—the public key represents your on-chain identity, while the private key proves ownership and the part of what to share and what I can do with my keys and info.

One of the biggest surprises for me was how much blockchain data is publicly accessible. Working with Solana's RPC calls made the idea of a “public database” feel real. you know at first I was like what the hell if everyone can know about me from my keypair something is wrongh here, but soom realised But then I realized that my public key isn't my secret. It's more like my public identity on the blockchain. The thing that actually proves ownership is my private key, and that's the part that must never be shared.

That was probably one of the biggest mindset shifts for me during these first two weeks.
soon I could query balances, accounts, and transaction history directly instead of going through a private backend like I normally would in Web2.

The comparison between traditional databases and Solana accounts also helped things click. Tables and rows became accounts, SQL queries became RPC calls, and writes happen through signed transactions.

But I'm definitely not at the point where everything makes sense yet. 😅 I’m still trying to understand the deeper relationship between accounts, programs, transactions, and instructions.

And honestly, that's what makes me excited for the next few weeks.
I started this challenge trying to understand Solana.
well I know I ahve slipped through few days first it was my healtha nd mood swings then I took some days off to blow off the steam and the part of how much I need that :) so no regrets there 😙
Now I'm gonna complete this journey & understand how to think in Solana, web 3, blockchain.

87 days to go! 🚀

My First Week with Solana Wallets

Well I guess it is a week now,I really don't know how quickly it passed and it is my 7th day of #100DaysOfSolana. I had really no idea when I started at that time to me, I thought like, "I guess it seems intersting and it would come in use after completing SHE fi S'16 "and now one moment that stood out was connecting my Phantom wallet to a web application I built and The biggest mindset shift for me was realizing that a wallet isn't just a place to store SOL-it's my on-chain identity. Coming from Web2, where identity revolves around emails and passwords, learning that a cryptographic keypair can represent ownership across an entire blockchain ecosystem was fascinating.

Along the way, I generated wallets programmatically, built a persistent wallet, explored SOL and lamports, connected browser wallets to a dApp, compared different wallet types, and learned how public and private keys work together to secure digital ownership.

here are some stuff i clicked througout this week

et interact with the Solana Devnet.

I'm excited to keep building and dive deeper into transactions, programs, and smart contracts in the coming weeks.

From Usernames to Keypairs: A Primer on Identity on Solana

As a Web2 developer, I always thought of identity as an email, username and password. Each app had its own login system and companies controlled my account access.

Learning Solana totally changed that perspective.

On Solana, your identity begins with a cryptographic keypair. Your public key is your wallet address, which is visible to everyone, and your private key is used to prove ownership when signing transactions. No usernames, no passwords, no central database controlling your account.

The best analogy I could draw was SSH keys. You prove your identity to a server with a private key, and Solana does the same for your wallet to the blockchain.

The difference is that you authenticate with the entire network instead of a single server.

Another realisation was that a wallet is more than just a place to hold SOL. The same identity works across decentralised apps, so you can own tokens, interact with smart contracts, and participate in governance without creating a new account for every platform.

There is no “Forgot Password” option here, unlike Web2. If you lose your private key or recovery phrase, there is no company that can restore access for you. That is all your responsibility and control

This shift from company-controlled identity to cryptographic ownership has been one of the most interesting concepts I’ve learned so far in my #100DaysOfSolana journey. It totally changes my perspective on digital identity and ownership.
