Inconsistent info about unblinded address prefixes

[dgpv]

https://elementsproject.org/elements-code-tutorial/confidential-transactions:

In the Elements protocol blinded addresses start with “CTE” and unblinded addresses start with a “2”,

https://elementsproject.org/features/confidential-transactions/addresses:

As you can see the unconfidential P2PKH address starts with a Q. P2SH start with H

Maybe the info about "2" prefix is out of date ?

Also it is not clear from the pages if it is possible to have multisignature confidential address. It would be good to include info if it is possible and if not, why.

The addresses page is a carry over from the old .org site and is potentially the one out of date. I will look into it and update accordingly. Thanks @dgpv . Also - noted your comments on multi-sig CT addresses.

The correct prefix for an unblinded address is 2.

You can validate this by creating a new address using getnewaddress and then passing that into validateaddress. That will return data similar to:

"isvalid": true,
  "address": "CTEoaMTWgfUKoST1fkitVWuHHueqiL4EcUjrwJXuZW9RWKbSzYNq8ttd8KzJr3KBMzxh6HC83CgroNLR",
  "scriptPubKey": "76a914f5b3992c73d1bee5844d840bbb30fe00f989c1fc88ac",
  "confidential_key": "028fafda60c741b4735c9b14fc768dbda05762f0355a09ceb8fcdd4da114c415bd",
  "unconfidential": "2dwpu6ECUS2NHMwwAmqCGJ6uNESr6tUmAS9",

The 'unconfidential' address is the unblinded one. I will raise aPR to change the address page and close this shortly. Thanks for spotting @dgpv

Fixed with PR #52

By the way @dgpv you can create a multi-sig using the 'createmultisig' command. This is detailed in the 'Block Signing' tutorial section. Something like:

MULTISIG=$(e1-cli createmultisig 2 '''["'''$PUBKEY1'''", "'''$PUBKEY2'''"]''')
REDEEMSCRIPT=$(echo $MULTISIG | jq '.redeemScript' | tr -d '"')

[dgpv]

Maybe it would be worth to mention that unblinded multisig addresses start with X, and blinded start with 'Azp'

Not sure if it would be suitable info for basic introduction pages, but maybe just as a footnote...

PR with info on multisig blinded addrs added to confidential addresses page: #54

[dgpv]

A little offtopic, but is the bech32 prefixes and format for blinded and unblinded addresses already decided ? (in 0.17.0 elements branch chainparams.cpp is still not changed, and googling for "elements sidechain bech32" does not give anything useful)

[instagibbs]

they have not been decided, no.

Closing - addressed with PR #54
