Hello Centrifuge community from Openbitlab team 👋

👪 **About us**  
We are four crypto builders, active in crypto since 2013 and with 6 years of experience in network validation.

We started block production activities in Lisk, the first-ever delegated-proof-of-stake network, and then we expanded our infrastructure to support innovative networks like Tezos, Substrate-based and Cosmos-based chains.  
We are active on 25+ blockchains, with $10m+ in staked value.  
_Mainnet_: Polkadot, Kusama, Lisk, Mina, Kujira, Mangata, StaFi, Tezos, Shiden, Moonriver, Moonbeam, E-money, Near, Quicksilver, Pylons, Amplitude, Aleph Zero.  
_Current and past Testnet_: Celestia, Persistence, Nomic, Origintrail, Shibuya, Aptos, Sui, Solana, Quicksilver, Stride, StafiHub, Archway.

We are also very active in governance, with more than 90% vote participation in Polkadot, Kusama, Kujira, and Quicksilver.

Thanks to our high responsiveness during critical situations, technical support in bug reporting and fixing, and top-quality performances of our nodes, we received delegations from several Foundation programs (Polkadot, Kusama, E-Money, StaFi, Moonriver, Moonbeam, Kujira), and have been whitelisted as bootstrap collators (Mangata, Shiden, Amplitude).

⛓ **Our Infrastructure**  
LXC container on bare metal dedicated server: AMD Ryzen 32 core, 132gb ram, 3.5TB NVME Datacenter edition, 1Gbs bandwidth. Our main server providers are Ikoula and OVH.

Our infrastructure also includes a backup server ready to replace our main server and located on another farm.

Our servers integrate various protection features:

- Zabbix agents connected to our Zabbix servers for real-time monitoring
- Encrypted disk, to protect data from physical access
- UFW firewall, to block access to unused ports
- Fail2Ban, to block incorrect authentications attempts
- SSH access through simple user (no direct root access allowed)
- Periodically change of the root password
- Custom monitoring tool for Centrifuge ([GitHub - openbitlab/srvcheck: Srvcheck helps you to monitor blockchain nodes](https://github.com/openbitlab/srvcheck))
- Additional monitoring with Prometheus+Grafana
