Austin Federa, the strategic director of the Solana Foundation, outlined the recent congestion issues on the Solana chain on the X platform. He stated that these issues stem from the implementation of the QUIC protocol and can be attributed to a known bottleneck issue. The solution is already on the roadmap. The main reason may be that the demand for Solana has increased at such a fast pace that within a few days, the problem went from "sufficient but needs improvement" to "insufficient." Austin Federa summarized that this issue is simply technical debt, a network stack that will almost certainly need to be completely rewritten later this year, while balancing important maintenance/improvement work.
