Introduction
Abstract
This document proposes a mechanism to set up multisig wallets securely.
Copyright
This BIP is licensed under the 2-clause BSD license.
Motivation
The Bitcoin multisig experience has been greatly streamlined under BIP-0174 (Partially Signed Bitcoin Transaction). However, what is still missing is a standardized process for setting up multisig wallets securely across different vendors.
There are a number of concerns when it comes to setting up a multisig wallet:
- Whether the multisig configuration, such as Signer membership, script type, derivation paths and number of signatures required, is correct and not tampered with.
- Whether the keys or the multisig configuration are leaked during the setup.
- Whether the Signer persists the multisig configuration in their respective storage, and under what format.
- Whether the Signer's storage is tamper-proof.
- Whether the Signer subsequently uses the multisig configuration to generate and verify receive and change addresses.
An attacker who can modify the multisig configuration can steal or hold funds for ransom by duping the user into sending funds to the wrong address. An attacker who cannot modify the configuration but can learn about the keys and/or the configuration can monitor transactions in the wallet, resulting in loss of privacy.
This proposal seeks to address concerns #1, #2 and #3: to mitigate the risk of tampering during the initial setup phase, and to define an interoperable multisig configuration format.
Concerns #4 and #5 should be handled by Signers and are out of scope of this proposal.
Specification
Prerequisites
This proposal assumes the parties in the multisig support BIP-0032, BIP-0322, the descriptor language and AES encryption.
File Extensions
All descriptor and key records should have a .bsms
file extension.
Encrypted data should have a .dat
extension.
Roles
Coordinator
The Coordinator initiates the multisig setup. The Coordinator determines what type of multisig is used and the exact policy script. If encryption is enabled, the Coordinator also distributes a shared secret or shared secrets to the parties involved for secure communication. The Coordinator gathers information from the Signers to generate a descriptor record. The Coordinator distributes the descriptor record back to the Signers.
Signer
The Signer is any software or hardware that controls the private keys
and can sign using those keys. The Signer is a participating member in
the multisig. Its responsibilities include providing its key record --
which contains a public key or an Extended Public Key (XPUB) -- to the
Coordinator, verifying that its KEY
is included in the descriptor
record and persisting the descriptor record in its storage.
Setup Process
Round 1
Coordinator
- The Coordinator creates a new multisig wallet creation session. The
Coordinator constructs the multisig script and its policy parameters,
such as the required number of signatures and the total number of
Signers (
M
andN
). - The session should expire after some time period determined by the Coordinator, e.g., 24 hours. The timeout allows the encryption key to have lower entropy.
- If encryption is enabled, the Coordinator distributes a secret
TOKEN
to each Signer over a secure channel. The Signer can use theTOKEN
to derive anENCRYPTION_KEY
. Refer to the #Encryption section below for details on theTOKEN
, the key derivation function and the encryption scheme. Depending on the use case, the Coordinator can decide whether to share one commonTOKEN
for all Signers, or to have one per Signer. - If encryption is disabled, the
TOKEN
is set to0x00
, and all the encryption/decryption steps below can be skipped.
Signer
- The Signer initiates the multisig wallet creation session by setting
the
TOKEN
. The Signer derives anENCRYPTION_KEY
from theTOKEN
. The Signer can keep the session open until a different value for theTOKEN
is set. - The Signer generates a key record by prompting the user for a multisig
derivation path and retrieves the
KEY
at that derivation path. Alternatively, the Signer can choose a path on behalf of the user. If the Signer chooses the path, it should try to avoid reusingKEY
s for different wallets. - The first line in the record must be the specification version
(
BSMS 1.0
as of this writing). The second line must be the hex-encodedTOKEN
. The third line must be theKEY
. TheKEY
is a public key or an XPUB plus the key origin information, written in the descriptor-defined format, i.e.:[{master key fingerprint}/{derivation path}]{KEY}
. The fourth line is a text description of the key, 80 characters maximum. The fifth line must be aSIG
, whereasSIG
is the signature generated by using the private key associated with the public key or XPUB to sign the first four lines. The signature should follow BIP-0322, legacy format accepted. - The Signer calculates the Message Authentication Code (
MAC
) for the record. The first 16 bytes of theMAC
serves as the Initialization Vector (IV
) for the encryption. - The Signer encrypts the key record with the
ENCRYPTION_KEY
andIV
. - The Signer encodes the
MAC
and the ciphertext into hexadecimal format, then concatenates the results:(MAC || ciphertext)
.
Round 2
Coordinator
- The Coordinator gathers key records from all participating Signers.
The Coordinator verifies that there are exactly
N
unique key records before the wallet setup session expires. - For each key record, the Coordinator extracts the
MAC
from the data, setsIV
to the first 16 bytes of theMAC
, then decrypts the ciphertext using theENCRYPTION_KEY
andIV
. - The Coordinator verifies that the included
MAC
is valid given the plaintext. - The Coordinator verifies that the key records have compatible specification versions.
- The Coordinator verifies that the included
SIG
is valid given theKEY
. - If all key records look good, the Coordinator fills in all necessary information to generate a descriptor record.
- The first line in the descriptor record must be the specification
version (
BSMS 1.0
as of this writing). The second line must be a descriptor or a descriptor template. The third line must be a comma-separated list of derivation path restrictions. The paths must start with/
and use non-hardened derivation. If there are no template or restrictions, it must sayNo path restrictions
. The fourth line must be the wallet's first address. If there are path restrictions, use the first address from the first path restriction. - The Coordinator calculates the
MAC
for the record. The first 16 bytes of theMAC
serves as theIV
for the encryption.. - The Coordinator encrypts the descriptor record with the
ENCRYPTION_KEY
andIV
. - The Coordinator encodes the
MAC
and the ciphertext into hexadecimal format, then concatenates the results:(MAC || ciphertext)
. - The Coordinator sends the encrypted descriptor record to all participating Signers.
Signer
- The Signer imports the descriptor record.
- The Signer extracts the
MAC
from the data, setsIV
to the first 16 bytes of theMAC
, then decrypts the ciphertext using theENCRYPTION_KEY
(derived from the open session) andIV
. - The Signer verifies that the included
MAC
is valid given the plaintext. - The Signer verifies that it can support the included specification version.
- The Signer verifies that it can support the descriptor or descriptor template.
- The Signer checks that its
KEY
is included in the descriptor or descriptor template, using path and fingerprint information provided. The check must perform an exact match on theKEY
s and not using shortcuts such as matching fingerprints, which is trivial to spoof. - The Signer verifies that it is compatible with the derivation path restrictions.
- The Signer verifies that the wallet's first address is valid.
- For confirmation, the Signer must display to the user the wallet's
first address and policy parameters, including, but not limited to:
the derivation path restrictions,
M
,N
, and the position(s) of the Signer's ownKEY
in the policy script. The total number of Signers,N
, is important to prevent aKEY
insertion attack. The position is important for scripts whereKEY
order matters. When applicable, all positions of theKEY
must be displayed. The full descriptor or descriptor template must also be available for review upon user request. - Parties must check with each other that all Signers have the same
confirmation (except for the
KEY
positions). - If all checks pass, the Signer must persist the descriptor record in its storage.
This completes the setup.
Encryption
The Token
We define three modes of encryption.
NO_ENCRYPTION
: theTOKEN
is set to0x00
. Encryption is disabled.STANDARD
: theTOKEN
is a 64-bit nonce.EXTENDED
: theTOKEN
is a 128-bit nonce.
The TOKEN
can be converted to one of these formats:
- A decimal number (recommended). The number must not exceed the maximum value of the nonce.
- A mnemonic phrase using
BIP-0039
word list. This would be 6 words in
STANDARD
mode. This encoding is not recommended inEXTENDED
mode as it can result in potential confusion between seed mnemonics andTOKEN
mnemonics. - A QR code.
- Other formats.
The flexibility in the data format allows each Signer to customize the User Experience based on its respective capabilities.
Key Derivation
The key derivation function is PBKDF2, with PRF = SHA512. Specifically:
DKey = PBKDF2(PRF, Password, Salt, c, dkLen)
Whereas:
- PRF = SHA512
- Password = "No SPOF"
- Salt =
TOKEN
- c = 2048
- dkLen = 256
- DKey = Derived
ENCRYPTION_KEY
Encryption Scheme
The encryption scheme is AES-256-CTR.
MAC = HMAC-SHA256(HMAC_Key, hex-encoded TOKEN || Data)
IV = First 16 bytes of MAC
Ciphertext = AES-256-CTR-Encrypt(Plaintext, DKey, IV)
Plaintext = AES-256-CTR-Decrypt(Ciphertext, DKey, IV)
Whereas:
- DKey =
ENCRYPTION_KEY
- HMAC_Key = SHA256(
ENCRYPTION_KEY
) - Data = the plaintext, e.g. the entire key record in round 1 and the entire descriptor record in round 2
The MAC
is to be sent along with the key and descriptor record, as
specified above. Because it is a MAC
over the entire plaintext, this
is essentially an
Encrypt-and-MAC
form of authenticated encryption.
Descriptor Template
The output descriptor language only supports one-dimensional lists. This proposal introduces a descriptor template to represent multi-dimensional lists:
XPUB/**
Whereas /**
can be replaced by any number of derivation path
restrictions.
A descriptor template must be accompanied by derivation path
restrictions. Signers should expand the template into concrete
descriptors by replacing /**
with the restrictions.
For example, the following template and derivation path restrictions:
wsh(sortedmulti(2,XPUB1/**,XPUB2/**))
/0/*,/1/*
Should translate to two concrete descriptors:
wsh(sortedmulti(2,XPUB1/0/*,XPUB2/0/*))
wsh(sortedmulti(2,XPUB1/1/*,XPUB2/1/*))
QR Codes
For signers that use QR codes to transmit data, key and descriptor records can be converted to QR codes, following the BCR standard.
Also refer to UR Type Definition for BIP44 Accounts and UR Type Definition for Bitcoin Output Descriptors for more details.
Compatibility
This specification is not backwards compatible with existing multisig implementations.
BSMS is opt-in, meaning existing multisig implementations can continue working as-is, with the caveat that they are likely to have various pitfalls. Some of the problems with existing solutions have been described in the #Motivation section.
To comply with this standard, a Signer must be able to persist the descriptor record in its storage.
To use BSMS for a multisig wallet, the user should wait until all participating Signers in the multisig have implemented BSMS.
Security
This proposal introduces two layers of protection. The first one is a
temporary, secret TOKEN
. The second one is the confirmation of the
wallet's first address.
The TOKEN
is used to encrypt the two rounds of communication between
the Signer and the Coordinator. A MAC
is also generated from the
TOKEN
and plaintext to authenticate the data being exchanged. The
TOKEN
is only needed during the setup phase, and can be safely
discarded afterwards. It is not recommended to use the same TOKEN
for
multiple wallet creation sessions.
The wallet's first address, on the other hand, can be used to verify the integrity of the multisig configuration. An attacker who tampers with the multisig configuration must also change the wallet's first address. Parties must check with each other that all Signers confirm to the same address and policy parameters to reduce the chance of tampering.
Privacy
Encryption helps improve the privacy of the wallet by avoiding sharing keys and descriptors in plaintext.
If the parties wish to have stronger privacy, it is recommended to use a
higher number of bits for the TOKEN
, and to completely erase knowledge
of the TOKEN
after the multisig wallet has been set up.
