 Problem: Nodes are hard  
The traditional Web 2.0 approach to scaling infrastructure uses multiple, indistinguishable servers managed by a load balancer, but with blockchain, applications can’t treat nodes indistinguishably because each node syncs and stores data from the blockchain asynchronously.
Running nodes behind a load balancer may result in inconsistent data since the latest block on each node might be different
Data inconsistencies force developers to introduce tons of complicated workarounds and lead to inevitable errors that crash applications and ruin user experience
Apps that run directly on nodes suffer high latency and downtime because nodes are general-purpose and not designed to be highly available.
Without a new approach to infrastructure design, developers are forced to choose between state consistency and scale.

 Solution: Alchemy Supernode
Alchemy Supernode is a new kind of infrastructure for decentralized applications with the following benefits:
Ensures data is always correct, real-time and in sync thanks to a proprietary coordinator service
Powers each piece of node functionality with a dedicated, distributed system -- the same systems used by Facebook and Amazon for achieving massive scale
Scales quickly and seamlessly so you can spend more time shipping products and delighting users
Includes enhanced API methods and upgraded WebSockets to continuously listen for changes and automatically handle reconnection and backfilling missed events
One-line infrastructure API that not only does all the jobs of a single node, but also comes with the uptime, availability, and necessities to run a production application.
Architecture
Alchemy Supernode's innovative architecture for web3 scales every piece of node functionality with dedicated distributed systems, and maintains real-time data correctness with a proprietary coordinator service.
