Over the final weekend, the Solana blockchain community suffered a significant outage for 7 hours knocking off validators out of the PoS consensus and halting the block manufacturing. This occurred because the bots managed to exploit the Solana-based NFT venture Candy Machine.
These bots then despatched a loopy quantity of site visitors thereby conducting record-breaking 4 million transactions, or 100 gigabits of knowledge per second. Three days later, Solana builders have arrived with an in depth report of the hack and the steps they might provoke to make the Solana blockchain extra resilient and sturdy.
Since the start of 2022, Solana has been a number of community congestion points with the bot exercise focused at NFT mints. The Solana builders have reported three main migrations at work to deal with community stability and resilience.
Three Major Changes to Solana Network
The Solana builders have shared some technical modifications that they might introduce to the Solana blockchain.
- QUIC – Solana builders will likely be implementing the Solana core protocols atop Google protocol QUIC. Currently, the Solana community implements a uncooked UDP-based protocol for passing transactions between RPC nodes and the present chief.
Solana explains: “Since UDP is connectionless and lacks both flow control and receipt acknowledgments, there is no meaningful way to discourage or mitigate abusive behavior”. Implementing core protocols on QUIC will carry classes and stream management like TCP.
- Stake-weighted transaction QoS: This will finish the present observe of indiscriminately accepting transactions on a first-come-first-serve foundation. The developer word: “Given that Solana is a PoS network, extending the utility of stake-weighting to transaction quality of service is a natural choice”.
Stake-weighted QoS is at the moment in parallel growth with QUIC. It shall ship a strong efficiency working alongside QUIC.
- Fee-based Execution Priority: Introducing a payment mannequin will give customers the power to categorical urgency for executing their transactions. The Solana builders word: “A new instruction is being introduced into the Compute Budget program, offering users the ability to specify an arbitrary “additional fee” to be collected upon execution of the transaction and its inclusion in a block”.
The transaction’s execution precedence weight will rely on the ratio of this payment to the requested compute items.
The Solana builders additional explained how payment buildings are coming to the Solana Blockchain.
