Data Integrity Proof Protocol middleware in Go
Simple protocol to provide your users with irrefutable proofs of the output of your service, as pioneered by dfuse.io
Using the protocol
Have your users pass the:
X-Data-Integrity-Proof: true
header in requests to your service. The protocol then returns an X-Data-Integrity-Proof hash back in the response headers.
If any data integrity issues arise, bring the returned payload along with the proof to claim your bounty. This will provide us with irrefutable proof that we did serve the payload.
Note: this will not work on websocket streams.
Integrate the middleware
In a Go service, use:
router := http.NewServeMux()
// Add routes to router
secret := "this is a randomly generated secret that is at least 32 bytes long"
_ = http.ListenAndServe(":8080", dipp.NewProofMiddleware(secret, router))
Validation
When you receive report of faulty data, users can provide the proof you gave them, with the payload they received.
Use the provided dipp-checker tool to do validation, which you can install with:
go get github.com/dfuse-io/dipp/cmd/dipp-checker
and run as:
dipp-checker \
"this is a randomly generated secret that is at least 32 bytes long" \
"the-proof-provided-by-the-user-in-hexadecimal" \
./path/to/payload.file
to validate integrity.
Initial work
The dfuse.io platform started this initiative alongside its Data Integrity Bounty Program.

Types ¶
type ProofMiddleware ¶
type ProofMiddleware struct {
// contains filtered or unexported fields
}
ProofMiddleware will hash the response and add a header. NOTE that this middleware will break Trailers added by calling code, after their WriteHeader() call.
func (*ProofMiddleware) ServeHTTP ¶
func (m *ProofMiddleware) ServeHTTP(w http.ResponseWriter, r *http.Request)
type ProofWriter ¶
type ProofWriter struct {
http.ResponseWriter
// contains filtered or unexported fields
}
func (*ProofWriter) WriteHeader ¶
func (w *ProofWriter) WriteHeader(code int)
