Accessing Data from Arweave with ao

There may be times in your ao development workflow that you want to access data from arweave. With ao your process can send an assignment instructing the network to provide that data to your Process.

In order, to request data from arweave, you simply call Assign with a list of processes you would like to assign the data to, and a Message which is the txid of a Message.

Assign({
  Processes = { ao.id },
  Message = 'message-id'
})

You can also call Send with a table of process ids in the Assignments parameter. This will tell the network to generate the Message and then assign it to all the process ids in the Assignments list.

Send({
  Target = ao.id,
  Data = 'Hello World',
  Assignments = { 'process-id-1', 'process-id-2' }
})

Why data from Arweave?

Your Process may need to access data from a message to make a decision about something, or you may want to add features to your Process via the data load feature. Or you may want to access a Message from a process without replicating the entire message.
