SHA-256 hashing
Generates a data block from a seed, then hashes it round after round, each round feeding the last digest back in. Pure CPU and memory bandwidth.

Explore workloads.
Run a workload on your own device right now, or read about the ones that are planned. Every finished run can be recorded on Robinhood Chain.
Plan your batch.
Pick a workload and a count. Time comes from your own past runs on this device; proof cost comes from the live gas price.

Estimated time
Proof cost if recorded
No finished run of this workload in this browser yet, so there is nothing to time against. Run it once and the estimate fills in. Gas uses about 253,000 units per proof at the current price. An estimate, not a quote.
Bring your own data.
Paste a JSON array or choose a picture from your disk in the runner. The data is read inside this tab and handed to a worker; it is never uploaded. Specifications you run can be shared and rerun by anyone.

How this list is read
This site's server asks a public Robinhood Chain endpoint for the latest block and the eleven before it (headers only), at most once every ten seconds for all visitors together. Rank is the position in the current sort. Transactions are counted from each block's list; gas used is the block total.
Compare the workloads below. Each one is free to run; recording a proof costs only gas from your wallet.

Prime sieve
Marks every composite number up to the limit and reports how many primes remain, the largest one and a checksum of all of them.

Image resize and compress
Resizes a generated sample or a picture you choose with a bilinear filter written in plain code, then compresses the result in the browser. The proof covers the resized pixels.

JSON transform
Parses a JSON array and runs a short pipeline of operations over it. Nothing is evaluated as code: each step is one of six fixed operations.

AI compute jobs
Model inference and data processing jobs on rented compute. This is a direction for the platform, not a service you can use today.

Run the same job specifications on servers instead of a browser tab, with the same proof format. Planned; no node is running.

Jobs stop when the tab closes. Results stay in this browser until you clear them, and a recorded proof stays on chain for good.
