List of Data Sources

• [arbitrum one]

• [ethereum mainnet]

Example

A more complex example pasted here:

name = "clique_arbitrumInfo"
spec-version = "1"
type = "Schema"

proof-type = ["TEE"]

[input]
address = { type = "string" }

[output]
createdBlock = { type = "u256", ref = "$tasks.clique_arbitrumCreatedBlock.data" }
lastActiveBlock = { type = "u256", ref = "$tasks.clique_arbitrumLastActiveBlock.data"}

[[tasks]]
name = "clique_arbitrumCreatedBlock"
proof-preference = "TEE"
[[tasks.input]]
address = { ref = "$input.address" }

[[tasks]]
name = "clique_arbitrumLastActiveBlock"
proof-preference = "TEE"
[[tasks.input]]
address = { ref = "$input.address" }

In this example, we create a schema (phantom task) which includes two tasks -- clique_arbitrumCreatedBlock, clique_arbitrumLastActiveBlock, and reconstruct their outputs into the struct that we want.
