Tour de SOL
Past
25 Jul 2019 - 12 Nov 2020
Tour de SOL was Solana’s early historical validator-focused incentivized testnet competition and stress-testing program that began in 2019. It invited validators, replicators, and security researchers to run nodes on the Solana testnet clusters to identify bugs and execute attacks in exchange for SOL token incentives. The rigorous program helped bootstrap the decentralized validator ecosystem ahead of the official Mainnet Beta launch.

How to join Solana - Tour de SOL?
Tour de SOL was a rigorous, highly technical competition designed to stress-test the early Solana testnet clusters prior to mainnet launch. The program officially booted its first decentralized cluster on July 25, 2019, with exactly 50 nodes (49 external plus Figment) participating. Validators were heavily incentivized to maintain high uptime, verify Proof of History, and submit critical bug reports to earn SOL token rewards and secure a mandatory prerequisite spot for the Solana Foundation stake delegation on Mainnet Beta.
During the highly active Stage 1, the technical community identified 13 issues (11 non-critical and 2 critical), including intentional DoS attacks orchestrated by network participants like Certus One and Chorus One. A notable exploit by Chorus One's 'Reisen' allowed for the massive theft of 500 million fake SOL tokens from the testnet. Top contributors and attackers could earn individual payouts that exceeded $100,000 per category. Additionally, the validator Dokia Capital earned the legendary nickname The Clustah-Killah after producing the final block that crashed the first incentivized cluster. Those interested in historical network performance can audit the official recaps.
