Small example of the steps needed to verify the merkle proofs of a transaction provided by WhatsOnChain.

	const crypto = require('crypto')
	const assert = require('assert')

	function sha256 (buffer) {
	assert(Buffer.isBuffer(buffer), `Argument must be a buffer, received ${typeof buffer}`)

	const hash = crypto.createHash('sha256')
	hash.update(buffer)
	return hash.digest()
	}
