In the blockchain world, most projects play it safe — they trade speed for decentralization, cost for simplicity.
Solana chose the harder path.
It was engineered not like a crypto experiment, but like a high-performance operating system — optimized from the ground up for speed, scale, and low cost.
Here's a deep dive into why Solana is fast and cheap, and more importantly, why it's so hard to copy.
---
I. Proof of History (PoH) – A Cryptographic Clock
The core bottleneck in most blockchains:
Validators need to agree on the order of transactions — a costly process.
🧠 Solana's solution: PoH
A cryptographic sequence of hashes, each embedding a verifiable timestamp.
Validators no longer wait or talk to agree on time — they just reference the clock.
⏱️ Result:
> Transactions can be processed immediately and concurrently, with provable order.
⛔ Why it’s hard to copy:
PoH isn't a plug-in; it’s tightly integrated into Solana’s entire architecture.
Requires deep knowledge of distributed systems + cryptographic time-keeping.
---
II. Parallel Runtime – Think Like a CPU
Most chains (e.g., Ethereum) are single-threaded — one transaction at a time.
🔧 Solana is multi-threaded:
It analyzes each transaction’s account access in advance.
If two transactions don’t touch the same accounts → they run in parallel.
🧠 This is known as the Transaction Scheduler.
🚀 Result:
> Solana achieves tens of thousands of TPS, not by batching — but by smart parallelism.
⛔ Why it’s hard to copy:
Requires a runtime capable of dynamic scheduling + memory safety.
Preventing race conditions in live environments is very hard.
---
III. Monolithic Architecture – All-In-One Power
New chains trend toward modular design (e.g., Celestia, Ethereum L2s) — separating execution, consensus, and data.
Solana rejects this:
It’s monolithic — everything runs in one optimized stack.
💡 Why?
Tighter integration = faster execution.
Fewer layers = less overhead, lower latency.
🧱 Result:
> Near-instant finality (~400ms), ultra-low fees (<$0.001), and a seamless UX.
⛔ Why it’s hard to copy:
Monolithic design requires deep full-stack optimization — few teams dare go that route.
Modular is easier to scale socially, but not technically.
---
IV. High Validator Requirements – But Worth It
To run a Solana validator, you need:
> 16-core CPU
128+ GB RAM
NVMe SSDs
High bandwidth (>1 Gbps)
💡 Why so demanding? → Solana prioritizes speed over maximum decentralization — then compensates with thousands of validators.
⛔ Why it’s hard to copy:
New chains don’t have a strong enough validator base to demand this level of hardware.
Without a healthy incentive structure, high-performance validators won’t show up.
---
V. Smart Contracts in Rust – Low-Level, High-Power
Unlike Ethereum’s EVM and Solidity, Solana uses Rust.
Why Rust?
Memory-safe, high-speed, close to the metal.
Allows tight control over performance.
Zero-cost abstractions → devs can squeeze every drop of efficiency.
⛔ Why it’s hard to copy:
Rust is hard to learn — especially for web devs.
Tooling is still maturing.
Building a developer community in Rust takes time and effort.
---
VI. QUIC – A Next-Gen Networking Stack
Solana uses QUIC (developed by Google), not TCP.
QUIC is built on UDP with better multiplexing, lower latency, and faster recovery.
It allows faster communication between nodes and clients.
🌐 Result:
> Faster block propagation, lower confirmation delay, and better real-time scaling.
⛔ Why it’s hard to copy:
Requires in-depth networking expertise.
Most chains don’t have networking engineers at this level.

🧠 Final Thoughts – You Can’t Just Fork Solana
Solana’s speed isn’t magic.
It’s the result of painstaking engineering choices:
✅ Custom consensus.
✅ Parallel execution.
✅ Monolithic architecture.
✅ Rust contracts.
✅ High validator throughput.
✅ Next-gen networking.
> You can fork Solana’s code,
but you can’t fork its engineering culture,
its validator ecosystem,
or its hard-won experience.
