Community Updates

- Introduced Loki, a dedicated Polygon MEV testnet for validators to smoothly transition to mev-bor on mainnet.

Polygon MEV testnet is live!

Dive in: https://blog.marlin.org/polygon-mev-testnet-is-live 

✅ Allows validators to test the stability of mev-bor without affecting the mainnet.

🤝 Display interoperability with other clients like core bor.

🌉 A testing ground for the Marlin gateway which acts as a bridge between mev-bor & different private relays.

🎯 Display the stability of the simultaneous usage of the public mempool using the P2P network & private relays. 

🔎 No token even on testnet needs to be staked. 

🤓 Prospective Bor validators need only register offchain with the testnet operator by filling https://form.typeform.com/to/meZlLpNS

🐟 To listen to MEV bundles, operators are required to run the Marlin gateway which connects to the Marlin relay.
