Application of BIPs 32, 38, 39, 44, and 63 to Altcoins

Bitcoin-explorer's (bx) command line interface (CLI), part of the libbitcoin tool suite, provides very substantial support for the following Bitcoin Improvement Proposals (BIP): 32, 38, 39, 44 and 63. BIP 44 capabilities supporting alternative cryptocurrency coins (altcoins) results from how bx BIP 32 commands are piped to one another. The application of the BIP 44 related table below facilitates the extension of BIPS 32 and 38 to altcoins. Behaviors associated with using column version values from the first row of the "BIP44 Altcoin Version Mapping Table" below are integrated into bitcoin-explorer's commands as defaults.

The libbitcoin team has a comprehensive understanding of this table's version values for the first row, Bitcoin (BTC), and has recently updated the bx CLI to support 100+ other altcoins. This awareness might create a common client-side code base, a merge, fostering convergence of existing Bitcoin altcoin code forks. However, such decisions will be at the discretion of altcoin main branch developers. Substantial server-side bitcoin-server node convergence opportunities will also emerge when libbitcoin supports pluggable consensus modules, but this Wiki article only mentions this concept for a later article.

The table below is a work-in-progress, but when completed will become an exemplar, providing important --version values. The utility of these values is demonstrated by example sets #1, #4, #5, and #6 below for the DASH altcoin (row entry 6, or coin type 5) to demonstrate how BIPs 32, 38, 39 and 44 can be tightly integrated with minor extensions to coherently support altcoins using a unified codebase. It is very important for wallet developers to understand the concepts being espoused here to minimize wallet complexity while supporting multiple currencies simultaneously using a common BIP 32 hierarchical deterministic (HD) framework.

The accuracy of portions of this table are not absolute (currently ~90% accuracy, with strong source code URL trace-ability to the right) until vetted by others, but the pattern for its application to altcoins is well understood. The table below extends and complements SLIP 44 referenced within BIP44. The table below also complements the List of Address Prefixes top Table's "Hex" column for row entries containing two hex digits.

An empirical trend within the table above is that version_WIF values range between 128 and 255 inclusive. Similarly, version_p2pkh values range between 0 and 127 inclusive. A noticeable exception is for CLAM. Both the version_p2pkh and version_p2sh columns are typically for addresses 160 bits in length. Notable exceptions are annotated for the Open Assets row where the version_p2pkh address is 168 bits in length, and Ripple (XRP) having 136 bits. Both the version_p2pkh and version_p2sh columns also contain information about base58check-encode starting address characters for a cell's version value. As long as the addresses are precisely 160 bits in length, such values also align with the lower table from the List of Address Prefixes.

General bx rules for commands supporting --version values that are 8-bit numbers in base10/decimal format:

  • Commands supporting version values associated with private key functionality for desired coin types will use values from the version_WIF column. Notable exceptions to this rule are are for ec-to-ek and ek-new. All "ek" related bx commands use the version_p2pkh column.
  • Commands supporting version values associated with single signature address functionality for desired coin types will use the version_p2pkh column.
  • Commands supporting version values associated with multi-signature address functionality for desired coin types will use the version_p2sh column.
  • The hd-new command enables a hierarchical deterministic extended private key prefix to be set by using the value from the version_hd_secret column.

It is anticipated this libbitcoin approach should be useful for synthesizing elliptic curve (EC) private keys, EC public keys, and addresses for 100+ altcoins. Certainly, there will be BIP/SLIP 44 registered coin types where it will not be readily apparent or appropriate to apply existing bx commands to arrive at associated WIF keys and/or addresses, e.g., use of hashing algorithms other than ripemd160, sha256, and sha512 such as Keccak sha3 technologies. Additionally, there will be altcoins that are not BIP/SLIP 44 registered that will have associated version_WIF and version_p2pkh values enabling bx to easily create private EC keys and associated addresses. Such unregistered coin types will be included in the table above, but each have a "coin type" annotation of "not registered" (NR). If client-side libbitcoin framework is adopted by developers, it will naturally enable extended BIP 38 support for those altcoins listed in the table above with significantly less overloading the "6P" encrypted EC private key prefix reserved for Bitcoin.

Finally, as a countermeasure to protect the Bitcoin cryptocurrency child prodigy as it grows through its pubescence phase, and to provide a foundation to jump start the establishment of numerous multi-coin wallet implementations, emphasis will first be applied towards populating the table above for altcoins that are BIP/SLIP 44 registered. It is anticipated once Bitcoin protocols(s) maturation/growth phase is completed, there will be a strong delineation between payment and settlement network processing layers that will implicitly support different levels of trust - with a blockchain settlement layer providing a greater amount of uncensored trust, and one or more payment mechanisms supporting greater scalability.

bx - Settings

The examples (i.e., 1 through 6) provided below for DASH in this Wiki article were chosen to function with the bitcoin-explorer bx.cfg file settings bundled with the bx package. This package bundled configuration file is tailored for Bitcoin (BTC). The environmental variable BX_CONFIG is frequently used to set the path of where a customized configuration file, such as bx.cfg, is saved that will override compiled bx defaults. Explicitly setting bx CLI --version values will override settings provided by a bx configuration file, e.g., bx.cfg.

The intent here is to briefly touch upon six important wallet configuration settings that influence altcoin client-side behaviors. To tailor the bx configuration file for DASH, the six bullet settings below are provided. Strong source code traceability back to DASH code base is provided below as hyperlinks.

  • wif_version = 204
  • pay_to_public_key_hash_version = 76
  • pay_to_script_hash_version = 16
  • hd_private_version = 50221772
  • hd_public_version = 50221816
  • transaction_version = 1

The EXT_SECRET_KEY DASH source code variable set to 0x02FE52CC is base16 encoded (or 50221772 in base10), and this numerical prefix causes DASH extended private keys to always start with "drkp". The EXT_PUBLIC_KEY DASH source code variable set to 0x02FE52F8 is base16 encoded (or 50221816 in base10), and this numerical prefix causes DASH extended private keys to always start with "drkv". Most altcoins have yet to customize such BIP 32 extended key prefix settings, and using prefixes for BTC and TEST don't really influence the net key synthesis results for altcoins. Hence, the examples for synthesizing DASH private keys and public addresses below will not utilize setting values 50221772 and 50221816. Finally, most alcoins with strong Bitcoin heritage are using transaction messaging format version 1.

bx - Wallet Commands

The table above is a "Rosetta Stone" for translating Bitcoin EC private keys and associated public keys and addresses to those used by a number of altcoins having strong Bitcoin key/address synthesis heritage. This cryptocurrency Rosetta Stone currently provides important --version values for the following bitcoin-explorer wallet commands:

  • ec-to-address ( use version_p2pkh column for addresses )
  • ec-to-wif ( use version_WIF column for private keys )

1) Combined BIP 32 and 44 CLI Example Set: Apply M/44’/5’/0’/0/0 to create a compressed DASH public addresses for up to 4 billions addresses for safe use by an online machine!!!

A. Be very afraid to use the weak brain wallet driven command sequence below on a computer that is online! Even with a very high entropy brain wallet, the approach below will will certainly be hacked unless you are a "cross domain solution" expert or apply multi-signature technology as risk mitigation. However, this brain wallet example is provided to enhance the understanding and repeatability of examples 1B and 1C below.

B. Is an equivalent M/44’/5’/0’/0 extended public key approach (to "A" immediately above) that protects the confidentiality of the master seed. The extended public key that is part of the echo command below must be created on an offline computer. However, don't be afraid of applying the extended public key (starts with xpub) command sequence approach below to online computers. However, for privacy reasons, don't share extended keys beginning with xpub for the Bitcoin Mainnet or tpub for Bitcoin Testnet.

If crypto-currencies become more widely adopted, the approach above will severely reduce the need for onerous eCommerce PCI-DSS compliance that is contractually required by credit card payment networks. This is a feature of permission-less blockchain technology! Permission-less blockchains don't require identity information to be utilized. This means permission-less cryptocurrency networks will naturally protect consumers from transaction payment identity theft for eCommerce transactions using a cryptocurrency transaction as payment/settlement. However, eCommerce servers accepting cryptographic currency payments utilizing such extended public keys must still protect the integrity of such extended public keys. Otherwise, eCommerce merchants risks customer payments being stolen or burned. Burned addresses are ones for which the associated EC private keys are not known.

It is also worth noting that a number of altcoins have already defined their own unique extended key prefixes, e.g., DASH (drkp/drkv), forked LTC (Ltpv/Ltub) and DOGE (dgpv/dgub) implementations. However, the application of wrong altcoin extended key prefixes won't interfere with the synthesis of proper types of EC private/public keys or addresses as long as --version values are applied correctly.

C. Demonstrates the generation of the next eCommerce DASH payment address (i.e., M/44’/5’/0’/0/1) to be applied by shopping cart checkout or point of sale (PoS) mechanisms, from the very same public extended key above (i.e., M/44’/5’/0’/0).

bx - Encoding Commands

Most encoding commands supporting --version are not restricted as to which columns to use since these commands can be used to develop WIF private keys, associated coin single & multisig addresses, single signature stealth addresses, and possibly multisig stealth addresses. The following bitcoin explorer "encoding commands" provide version support:

  • address-embed ( no rules(s) yet for which version column(s) to apply )
  • address-encode ( use version_p2pkh column for single signature addresses, version_p2sh column for creating multisig addresses, single signature stealth addresses???, multisig stealth addresses??? )
  • base58check-encode ( use version_WIF column for private keys, version_p2pkh column for single signature addresses )
  • wrap-encode ( use version_WIF column for private keys, version_p2pkh column for single signature addresses, version_p2sh column for multisig addresses )

The following bitcoin-explorer encoding command should not be extended to accommodate a --version value:

4) Combined BIP 32 and 44 Compliant CLI Example Set: Apply m/44’/5’/0’/0/0 example to create a compressed DASH private key.

A. Synthesized compressed EC private key below is derived from a very weak cryptographical brain wallet. Note that this affords absolutely no protection of the master seed that feeds the hd-new. The piped "sed 's/$/01/'" command below appends the private key with "01" to signal downstream public key software to create companion compressed EC public keys in a compressed format. Without this extra suffix, the EC public key will be in the uncompressed format that requires twice the memory of compressed keys.

B. This m/44’/5’/0’/0 extended private key synthesis approach, derived from the same cryptographically weak brain wallet, also protects the confidentiality of the master seed. However, extreme care must be exercised to protect the confidentiality of extended private keys starting with xprv for BTC or tprv for TEST. A compromise of the confidentiality of m/44’/5’/0’/0 for this DASH example will likely compromise the funds for up ~4 billion synthesized addresses.

bx - Key Encryption Commands

The table above also complements Altchain Encrypted Private Keys by supporting the following bitcoin-explorer "encrypted key" commands to extend BIP 38 functionality to altcoins:

  • ec-to-ek ( use version_p2pkh column for addresses )
  • ek-address ( use version_p2pkh column for addresses )
  • ek-new ( use version_p2pkh column for addresses )
  • ek-public ( use version_p2pkh column for addresses )

(Please note the information below needs to be cross correlated with security recommendations to arrive at a good processes for outsourcing the minting of coins or engraving of notes by owners of DASH funds.)

A. "Brain seed" - Something like this step should be performed by the minter/engraver on a per customer request basis to be unique to ensure minter/engraver has a countermeasure in place so not to be treated as a money transmitter. The number generated here is not shared until after minting or engraving product is shipped to the customer.

Xc3cYycMHt9vtBjMcUJshBH34QqfZnbEyu

It is very important to understand that minted/(engraved) coins/(notes) using a mechanism like the one described immediately above will not generally be transferable to 3rd parties without considerable trust between the original owner/curator of the minted/(engraved) coins/(notes) and downstream parties gaining physical possession (9/10th of ownership) of such coins/(notes). Without a form of cryptographic "bonding", the lack of trust by most secondhand coin/(note) holders will naturally invoke a "bearer bond" behavior by others desiring to take full control of the value tied to such physical cryptographic private key.

For risk reasons, this will cause secondhand coin/(note) holders to immediately break a coin's/(note's) seal to access its private key, and immediately "sweep"/(NOT IMPORT) this private key using an online wallet application. This will cause a new blockchain P2PKH transaction to transfer cryptograhic monetary rights to a separate trusted private key of theirs. This process severs previous immutable blockchain accounting value that was previously tied to such a physical coin or note, and it extrinsically becomes cryptographically worthless. Be aware that absolutely no cold storage trust should be given to any BIP 38 instrument that has "any history" of funds being spent. Numerous deposits being swept are fine, withdrawals absolutely not because the funds will no longer be considered in cold storage!

With the application of strong, high entropy, passwords/passphrases, BIP 38 functionality allows computer printing devices with untrusted firmware and network connections to safely print paper wallets for storage at multiple inconspicuous locations, not necessarily requiring the use of a safe of deposit boxes and possibly guard services. Also, numismatic collectors can obtain very professional looking coins or notes minted or engraved by un-trusted minters or engravers if a BIP 38 "EC Multiply Mode" exchange protocol is utilized. However, mints/(engravers) without "money transmitter" licenses need to take extra precautions to ensure their product is shipped before associated blockchain value can be attributed to it. One side effect of mints/(engravers) shipping product without being loaded is there are no initial branded assurances as to the accuracy of a coin's or note's cryptographic monetary value.

In summary, both BIP 38 AES 256 bit encryption and decryption along with BIP 38 EC Multiply Mode can be used to create cold storage wallets for safe long-term keeping. There is the expectation from secondhand parties that minted/(engraved) coins/(notes) have blockchain "bearer bond" characteristics, and after taking possession will almost immediately be redeemed. If such coins/(notes) have tamper resistant secrets affixed to them to attain such a "bearer bond" characteristic, they must be physically guarded, an thus have associated commodity cantango storage cost characteristics.

Printing your own BIP 38 paper wallets with a trusted computer printer can engender greater privacy by helping to prevent others from ascertaining your cryptographic worth. It is also alright to keep BIP 38 paper wallets in multiple inconspicuous locations if they don't have monetary denominations printed on them, public addresses nor information printed on them indicating who the owner is or POCs are. This presents an interesting cantango resistant characteristic for cryptocurrency savers that has never existed before in the physical world. If monetary denominations, public addresses or contact information is printed on BIP 38 wallets there will be an associated storage cost, but not as much as that for minted/(engraved) coins/(notes) with "bearer bond" characteristics.

Contrast ./xmr results above from what https://xmr.llcoins.net/addresstests.html yields using e62551cad9fe0f05d7c84cf6a0ef7e8fc0534c2694279fc6e46d38f21a3f6ed3 as the "Hexadecimal Seed". There are two sets of Electrum seed words that result in the same Monero address. Subtle differences can be easily explained by knowing if the seed is already normalized (i.e., sc_reduce32 is applied) or not. Also, ./xmr source code is located here.
