How is this realizing microtransactions in a decentralized manner?<p>Having to pay a few cents in transaction fees to get a transaction included on the Bitcoin blockchain does not seem like a great platform for true microtransactions(say &lt;$1).<p>21 offers their own microtransaction service, but that&#x27;s just a centralized shared wallet&#x2F;ledger that offers nothing new. There are multiple centralized services where you can send someone else bitcoin.<p>The only thing that has potential is payment channels, but I&#x27;m not sure how they are going to be implemented in a way that bypasses the Bitcoin blockchain&#x27;s miner fee.
