Completed Task 3 of @AckeeBlockchain School of Solana. Built a Vault - Deposit and withdraw tokens - Lock / Unlock logic - Added account constraints to allow only vault authority to withdraw tokens - Multi user deposit - Other mini checks Building on Solana is fun! 😊

Better Rust Better Anchor Better formatting Better Solana programs ✌️

Building a Solana program and wanted to send SOL into an account. I was looking for a token account field in the struct, forgetting that every account has an inbuilt lamport field. Yes, every Solana account has lamports, owner, executable, rent_epoch, data fields. GM

You'll think => and $ are not used in rust until you start writing procedural and declarative macros.

What enforces order on chain ? POH. It's a VDF (verifiable delay function) that adds a stamp to entries on chain, so each validator can know when the tx occurred. It can be recomputed and the new hash is dependent on the former one. The POH itself behaves like a Blockchain.

In this type of tech, the block propagation process is streamlined and then the next validator gets the block to continue its propagation. Even during consensus, the chain doesn't stop. The protocol that makes it possible for the chain to do all these ? TURBINE !

Another day to know something different about solana. Other Blockchains construct entire blocks before broadcasting them. Solana does this differently by assembling and streaming blocks like Netflix 🙂‍↔️, significantly reducing latency. GM GM

Improving dev experience on Solana 💯

@idorocodes, I see you, doing great work, clear doubts and confusion about solana, keep going

Building a mini cryptography tool in Rust with ed25519🦀 - Generate public and private keys randomly - Generate deterministic public and private keys with seed i.e same keys for same seed - Sign messages with the generated key - Verify signatures - Hex output

Completed Task 2 of @AckeeBlockchain School of Solana season 8. Dived deep into Rust: Options, Results, Traits, Enums,pattern matching, Structs & Vectors. 30 tests. 30 passed. 0 failed 🙂‍↔️👌 Built everything on @zeddotdev , insanely fast IDE 🔥

I'll say this again. They are not the same. Solana consensus mechanism is POS Solana consensus algorithm is Tower BFT Solana consensus mechanism describes how to select validators. Solana consensus algorithm describes what validators do after they are selected.

Heard about SWQoS (Stake Weighted Quality of Service) ? In conjunction with QUIC, it basically allows tx forwarded from high stake validators to be prioritised. Thereby reducing Sybil attacks. Imagine getting speed and Sybil resistance all at once 😄. @solana tech >>>

How does Solana forward tx from RPCs to validators? Early on, it used UDP for speed, but bots spammed the network during NFT mints, causing chaos. So Solana switched to QUIC, a faster, smarter protocol by Google. @solana is bullish on speed 👌 Used Https/3 ? you've used QUIC

RPC nodes are Solana’s gateways, they don’t make blocks, but they let you talk to the chain. Since Solana skips mempools, RPCs must forward txs directly to each slot’s leader. Speed is everything. Fav RPC? @heliuslabs. Fast, reliable, and dev-friendly GM GM 😄

A leader reigns for ~400ms on Solana. The leader receives tx from RPC Executes the with Sealevel Bundle them into blocks Propagate them with turbine, which shreds and blasts it throughout the network. All in 400ms 😎 Literally a chain that finalises tx before you blink.

Solana skips mempools, transactions go straight to the leader. Before every epoch (~2 days), a leader schedule is created. Each epoch is split into slots ~ 400ms each, and every slot has its own leader. Leaving each validator just 400ms to produce a block. Speed? Insane. Gm

The smallest unit of Solana is called Lamport, and 1 sol is a billion Lamport. Named after this great man. The Goat of distributed systems. Leslie Lamport. His homepage is great btw :

Yes! 👌 Program and tests, everything in rust 😌

Launched wearust just to have a Rust crate to my name… now 1.5k+ downloads after 2 months, it’s powering over a thousand Rust projects. 🙌 Big thanks to all the rusteaceans out there! Improvements dropping soon,stay tuned!
