Introduction

Solana shreds are the earliest block data available on the Solana chain. Shred Stream pushes raw Solana shreds via UDP, which is of great help for high-frequency trading, order flow analysis, block reconstruction and other latency-sensitive needs.

Direction for use

Log in to the portal website of Flash Block. https://flashblock.trade/login

Click on "Free Trial" or "Create Stream", fill in the IP and port for receiving the data stream and select the region. After configuration, please ensure that your firewall allows the port for receiving shreds data. Listen to the local UDP port to receive the shreds data stream.

View firewall rules :  sudo ufw status
Port opening :  sudo ufw allow <port\>/udp
Reload to effective :  sudo ufw reload

After the configuration is completed, simply verify if there is a data stream by using the command "nc -ul <port>", and if data is observed, it indicates that the stream service is pushing data normally.
