# Blockchain Listing Service

The Blockchain Listing Service is a distributed service where listings of for-sale real estate assets are stored on the blockchain so as to create an open source data set of listing data. This data is collected so as to be resource that may be consumed by other dApps provided by Plano and others.

### Access <a href="#f632t5g9s0g1" id="f632t5g9s0g1"></a>

The listing service does not store or maintain any actual listing data. Instead, the service provides a specific design pattern to which new and existing providers of data can adapt. This service pattern is similar to that used by other distributed applications within the Web3.0 space such as the Ethereum Name Service (ENS).

Use of this pattern by Plano and other providers will break the current monopolies on data that existing MLS providers have.
