What's the best way to use Ethereum Attestation Service? Is there a good website where I can view my own EAS and give them to others?

You absolutely can use @witness with EAS schemas for offchain attestations! @web3pm and @j4ck.eth from @icebreaker are doing this to remove the upfront and dynamic cost mandated by onchain attestations

We also cross deployed /eas schemas on both Optimism and ETH Mainnet in case you want to post back offchain attestations that reference initial offchain attestations which have been witnessed onchain via @witness No resolver address so anyone can use them. The way we use them is: a) Icebreaker makes an offchain attestation using any /eas schema (private or public) and records the uid b) Icebreaker calls witness postLeafHash in a daily job with the attestation UID and records the leafIndex c) Icebreaker makes an offchain public attestation using our witness schema with isWitnessed = true, leafIndex = b.leafIndex, and refUid = a.uid This adds some nice contextual documentation to the original attestation in EAS where you can see the subsequent leaf where it has been witnessed onchain: https://easscan.org/offchain/attestation/view/0x2f79dc626b2ff923f1db5f18be8a5d4dda28154492a2b8adc71bde7c695fa02e

Scroll down to the bottom in that EAS link to see the referencing attestation with the witness leafIndex
