Compatibility, measured
A GPU-secured network for Ethereum-compatible applications and verifiable computation. Compatibility is a product deliverable here, not a sentence: every row below is a test that ran against the devnet from the repository (tools/reference-apps/compat/run.mjs), with its evidence, and a row that could not run says so and why. Devnet, no value.
Last run: not run yet. 0 passed, 0 failed, 0 untested. Sender none.
Three boundaries hold for everything on this page: proven execution is not finality; EVM compatibility is not Ethereum security; ZK is not privacy. The four words included, executed, proven and finalised are defined on /receipt.

What the differences mean for an application
- Block context:
block.coinbase is the miner of the DAG block that first included the transaction, so one chain block can carry transactions with different coinbases; code that pays or trusts block.coinbase as "the block producer" sees several producers per block.
- Randomness:
block.prevrandao derives from the chain's epoch seed and holds for an epoch, so it is not fresh per block and must not seed a lottery or a commitment; use an application-level randomness source.
- Two-dimensional fees: every transaction pays execution gas and proving gas; the node folds the second into the gas it quotes, so a wallet that quotes from the node (eth_estimateGas, eth_gasPrice, eth_feeHistory) is covered and a wallet with Ethereum's constants (21,000 for a transfer) is not; the receipt carries the split under
igneum (pgasUsed, provingBaseFeePerGas, burnedProvingFee, burnedExecutionBaseFee, minerTip).
