The Solana blockchain has been undergoing some major challenges and network congestion issues in the past two days. As per data from Phantom the Solana blockchain has been currently experiencing congestion for the second time in the last 48 hours which could lead to transaction delay or failure. The recent congestion in Solana has been in Anza Network’s validator client implementation, Agave. In its recent post, Anza explains that the primary concern regarding network congestion has been identified to stem from a QUIC implementation and the behavior of the Agave validator client.
