The blockchain is an intriguing decentralized approach to content storage.

If you’ve ever tried using a blockchain-based application, however, you’ve probably discovered one of its biggest problems: network latency.

That is, it takes a very long time for the server chain to respond to queries with content.

It’s not so much slower than traditional centralized server banks. Usually, a decentralized chain of servers will take a few seconds longer to respond to queries. However, in the age of ever-increasing content delivery speed, it’s hard for users to put up with those extra seconds in daily use.

Why Does Blockchain have Latency?

The very same feature that makes blockchain technology so powerful is the same feature that slows it down. The data that servers deliver – in this case, web content – needs to be authenticated or verified by other servers on the blockchain before it’s served to the user.

That involves more queries and responses, and those add up to significant amounts of time from the initial query to a final response.

In some cases, servers need to communicate with servers across the world for authentication before responding to the end-user.

Substratum Uses Machine Learning To Cut Latency

Substratum’s goal is to eliminate every barrier to widespread adoption of blockchain technology, and high latency is one of the first barriers they tackled.

Their solution uses machine learning, or artificial intelligence, to optimize server response time by incorporating geolocation data into the querying process. Their blockchain system will cut latency by working only with those servers closest to the end-user.

When an end-user requests web content, the intelligent algorithm directs the query to the closest working server. That server, in turn, will authenticate its content with its closest servers. By cutting the latency of each query-response cycle, the total latency drops significantly.

With the latency issue addressed, we are that much closer to a federated, distributed internet for all!
