The Problem with Existing Solutions
Most blockchain timestamping services anchor to Ethereum. While Ethereum is secure and decentralized, it was not designed for high-frequency, low-cost operations. A single transaction on Ethereum mainnet can cost $2–$50 depending on network congestion. For a service that anchors thousands of proofs per day, this is economically unsustainable.
Enter Solana
Solana was built from the ground up for high throughput and low latency. With its unique Proof of History (PoH) consensus mechanism combined with Proof of Stake (PoS), Solana achieves:
- **400ms block times** — Proofs are anchored almost instantly
- **Low per-proof fees** — Base fee ~$0.00025 per transaction
- **2,000+ validators** — Highly decentralized network
- **4,000+ TPS sustained** — Real-world throughput without congestion
The Math
Let's compare the cost of anchoring 1,000 proofs per day for one month:
| Chain | Cost per Tx | Monthly Cost (1K/day) |
| Ethereum | $5.00 | $150,000 |
| Solana | $0.00025 | $7.50 |
The difference is staggering. Solana makes it possible to offer a free tier with 1,000 proofs per month — something that would be impossible on Ethereum.
Why Not Arbitrum or Optimism?
Ethereum L2s like Arbitrum and Optimism offer lower fees than mainnet, but they still cost $0.01–$0.10 per transaction. More importantly, they inherit Ethereum's 12-second block times. For proof anchoring where speed matters, Solana's 400ms block time is unbeatable.
Our Commitment
We chose Solana not because it's trendy, but because it's the only chain that meets our requirements for speed, cost, and decentralization. We are Solana-native, period.
