A prevalent issue with many token projects is scalability, particularly as it relates to microtransactions. High gas fees make these small transactions uneconomical. This is not an issue for sales-based rewards on the Signal Marketplace, but it is an issue for view-based rewards. Our current workaround for this is transaction batching, where reward transactions are only executed when theyve reached a minimum required batch count, such that the gas fees do not exceed the rewards themselves. For general intents and purposes, this works just fine. However, because it requires us to manage the batch data, it is not fully decentralized. To address this, we will be exploring some blockchain alternatives (i.e. EOS) while also keeping a close eye on scalability developments in the Ethereum world (Sharding, etc.).
Don't limit yourselves to blockchain-based consensus, there are the DAG solutions and hashgraph. Maybe one of your team members should experiment building upon these platforms.
