In addition to the preceding proposal, pipelining of block propagation has also been suggested, which is based on the idea of anticipating the availability of a block.
In this scheme, the availability of a block is already announced without waiting for actual block availability, thus reducing the round-trip time between nodes.
How New Blocks Spread Across the Network
Finally, the problem of long distances between transaction originator and nodes also contributes toward the slowdown of block propagation.
It has been shown in the research conducted by Christian Decker that connectivity increase can reduce propagation delay of blocks and transactions.
This is possible because, if at any one time the Bitcoin node is connected to many other nodes, it will result in reducing the distance between nodes and can speed up information propagation on the network.
An elegant solution to scalability issues will most likely be a combination of some or all of the aforementioned general approaches.
A number of initiatives taken in order to address scalability and security issues in blockchains are now almost ready for implementation or already implemented.
For example, Bitcoin Segregated Witness (SegWit) is a proposal that can help massively with scalability and only needs a soft fork in order for it to be implemented.
Why This Matters for Blockchain Technology
The key idea behind so-called SegWit is to separate signature data from the transactions, which resolves the transaction malleability issue and allows block size increase, thus resulting in increased throughput.

Conclusion
Block propagation represents one of the many innovative layers that make blockchain technology so powerful and transformative. As distributed systems continue to evolve, a solid understanding of these core concepts becomes increasingly valuable — not just for developers, but for anyone building, investing in, or working alongside blockchain-powered systems.
Whether you are just starting your blockchain journey or deepening existing expertise, mastering these fundamentals gives you the tools to think clearly about decentralized systems and make smarter decisions in this rapidly evolving space.
