Monad, a leader in blockchain scalability solutions, announced RaptorCast, its latest protocol innovation aimed at refining block propagation techniques. Co-founder Keone Hong emphasizes that existing blockchain systems struggle to efficiently distribute large blocks globally without compromising speed or decentralization.

What are the challenges with block sending?
Increasing block size to improve performance can tax the process of transferring large data sets and slow down transactions. This scenario creates an unstable triangle in which speed, decentralization, and bandwidth must be carefully balanced within a high-performance blockchain framework.
How does RaptorCast work?
RaptorCast introduces an innovative approach by dividing blocks into encoded fragments. These fragments are spread throughout the network using a fountain-type error correction algorithm. The validator only needs to collect enough fragments to reconstruct the entire block. This is a way to optimize network efficiency and reliability.
This system differs from traditional block distribution by allocating encrypted pieces based on stake weight and allowing validators to propagate fragments between peers. RaptorCast guarantees that data can be reconstructed even with some loss, optimizing bandwidth allocation across the network.
Monad's team claims that RaptorCast enables high transaction capacity without compromising global decentralization.
How do you value speed and security?
With RaptorCast, blocks of approximately 4,000 transactions are created in 400 milliseconds and protected by cryptographic auditing and packet validation to maintain secure and efficient data flow. This system also reliably protects the network from problems that occur during multihop transmission.
Keone Hon emphasizes the importance of balancing high transactional capacity with the physical constraints of the network. The main goal of this protocol is to efficiently distribute large blocks without overburdening validators.
Additionally, Monad’s recent partnership with Alchemy Pay introduces a new means to purchase MON tokens using traditional payment methods. This integration aims to make the Monad ecosystem more accessible and user-friendly.
As Monad progresses with RaptorCast, the potential of this protocol to significantly improve the performance and efficiency of blockchain networks becomes increasingly clear. The main conclusions are:
- Distribution of encoded fragments minimizes the risk of data loss.
- Stake-based fragment allocation powers decentralized validation.
- 400ms block creation ensures fast processing.
The introduction of RaptorCast represents a promising advance in blockchain technology, with the potential to reshape the way networks manage large-scale transactions and maintain decentralization on a global scale.
