Bech32 adoption

2022-11-02T20:17:34Z

Yojoots: /* Web Wallets / Wallet Service Providers */ update Fireblocks "Send to Bech32m" to Yes

[[Bech32]] is a bitcoin [[address]] format specified by [[BIP 0173]]. It is used for the native segwit version 0 output types, P2WPKH and P2WSH. The upcoming [[Taproot]] softfork will add another output type called Pay to Taproot (P2TR). P2TR outputs and future native segwit versions will be using an updated variant of [[Bech32]], called [[Bech32m]] (specified by [[BIP 0350]]). This page tracks the adoption of [[Bech32]] and [[Bech32m]].

Ideally wallets and services would first support ''sending to'' new addresses. When most wallets and services support sending to the new address type, people are more likely to adopt it for receiving.

The amount of bech32 addresses on the blockchain is tracked on this website: https://p2sh.info/dashboard/db/bech32-statistics?orgId=1

=== Hardware Wallets ===

Hardware wallet manufacturers typically publish a web wallet or browser add-on wallet for use with their hardware. Users can also sometimes connect their hardware wallet to a software wallet like [[Electrum]].

=== Blockchain Explorers ===

To investigate bech32 capability, you can use mainnet TXIDs <code>4ef47f6eb681d5d9fa2f7e16336cd629303c635e8da51e425b76088be9c8744c</code> and <code>514a33f1d46179b89e1fea7bbb07b682ab14083a276979f91038369d1a8d689b</code> or look up the addresses <code>bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq</code> and <code>bc1qc7slrfxkknqcq2jevvvkdgvrt8080852dfjewde450xdlk4ugp7szw5tk9</code>.

Some blockchain explorers can only parse the bech32 address and display it, they don't build an index so users cannot search for bech32 addresses.

To verify bech32m readiness, you can look up the mainnet TXID <code>b10c007c60e14f9d087e0291d4d0c7869697c6681d979c6639dbd960792b4d41</code> on which the first output should be addressed as <code>bc1pqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqsyjer9e</code>. Note that the superseded bech32 encoding only differs in the last six characters that encode the checksum: <code>bc1pqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqs_3wf0qm_</code>.

Bech32 adoption

2022-11-02T00:22:32Z

Yojoots: /* Exchanges */ update River.com "Send to Bech32m" status to Yes

[[Bech32]] is a bitcoin [[address]] format specified by [[BIP 0173]]. It is used for the native segwit version 0 output types, P2WPKH and P2WSH. The upcoming [[Taproot]] softfork will add another output type called Pay to Taproot (P2TR). P2TR outputs and future native segwit versions will be using an updated variant of [[Bech32]], called [[Bech32m]] (specified by [[BIP 0350]]). This page tracks the adoption of [[Bech32]] and [[Bech32m]].

Ideally wallets and services would first support ''sending to'' new addresses. When most wallets and services support sending to the new address type, people are more likely to adopt it for receiving.

The amount of bech32 addresses on the blockchain is tracked on this website: https://p2sh.info/dashboard/db/bech32-statistics?orgId=1

=== Blockchain Explorers ===

To investigate bech32 capability, you can use mainnet TXIDs <code>4ef47f6eb681d5d9fa2f7e16336cd629303c635e8da51e425b76088be9c8744c</code> and <code>514a33f1d46179b89e1fea7bbb07b682ab14083a276979f91038369d1a8d689b</code> or look up the addresses <code>bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq</code> and <code>bc1qc7slrfxkknqcq2jevvvkdgvrt8080852dfjewde450xdlk4ugp7szw5tk9</code>.

Some blockchain explorers can only parse the bech32 address and display it, they don't build an index so users cannot search for bech32 addresses.

To verify bech32m readiness, you can look up the mainnet TXID <code>b10c007c60e14f9d087e0291d4d0c7869697c6681d979c6639dbd960792b4d41</code> on which the first output should be addressed as <code>bc1pqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqsyjer9e</code>. Note that the superseded bech32 encoding only differs in the last six characters that encode the checksum: <code>bc1pqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqs_3wf0qm_</code>.

Technical background of version 1 Bitcoin addresses

2021-02-25T06:45:13Z

Yojoots: Update Base58Check address formatting details

[[File:PubKeyToAddr.png|thumb|right|Conversion from ECDSA public key to Bitcoin Address]]
This article may be too technical for some users. The more basic article on [[Address|Bitcoin Addresses]] may be more appropriate.

A [[Bitcoin address]] is a 160-bit hash of the public portion of a public/private [[Wikipedia:Elliptic_Curve_DSA|ECDSA]] keypair. Using [[Wikipedia:Public-key_cryptography|public-key cryptography]], you can "sign" data with your [[private key]] and anyone who knows your public key can verify that the signature is valid.

A new keypair is generated for each receiving address (with newer [[Deterministic wallet | HD wallets]], this is done deterministically).
The public key and their associated private keys (or the seed needed to generate them) are stored in the [[wallet]] data file.
This is the only file users should need to [[backup|backup]].
A "send" transaction to a specific Bitcoin address requires that the corresponding wallet knows the private key implementing it.
This has the implication that if you create an address and receive coins to that address, then restore the wallet from an earlier backup, before the address was generated, then the coins received with that address are lost; this is not an issue for HD wallets where all addresses are generated from a single seed.
Addresses are added to an address [[key pool]] prior to being used for receiving coins. If you lose your wallet entirely, all of your coins are lost and can never be recovered.

Bitcoin allows you to create as many addresses as you want, and use a new one for every transaction.
There is no "master address": the "Your Bitcoin address" area in some wallet UIs has no special importance.
It's only there for your convenience, and it should change automatically when used.

Bitcoin addresses contain a built-in check code, so it's generally not possible to send Bitcoins to a mistyped address. However, if the address is well-formed but no one owns it (or the owner lost their wallet.dat), any coins sent to that address will be lost forever.

Hash values and the checksum data are converted to an alpha-numeric representation using a custom scheme: the [[Base58Check encoding]] scheme. Under Base58Check, addresses can contain all alphanumeric characters except 0, O, I, and l. Mainnet [[P2PKH]] addresses start with <code>1</code>, while [[P2SH]] addresses start with <code>3</code> ([[Bech32]] addresses start with <code>bc1</code> and do not use Base58Check encoding). Testnet addresses usually start with <code>m</code> or <code>n</code>. Mainnet addresses can be 25-34 characters in length, and testnet addresses can be 26-34 characters in length. Most addresses are 33 or 34 characters long.

== Collisions (lack thereof) ==
Since Bitcoin addresses are basically random numbers, it is possible, although extremely unlikely, for two people to independently generate the same address. This is called a [[Wikipedia:Collision_(computer_science)|collision]]. If this happens, then both the original owner of the address and the colliding owner could spend money sent to that address. It would not be possible for the colliding person to spend the original owner's entire wallet (or vice versa).

But because the space of possible addresses is so astronomically large it is more likely that the Earth is destroyed in the next 5 seconds, than that a collision occur in the next millenium.

==How to create Bitcoin Address==

The correct way to create a Bitcoin address is to use well tested, open source, peer reviewed wallet software. Manually handling keys has resulted in funds loss over and over again. Unlike other centralized systems losses in Bitcoin are usually unrecoverable.

Here is a brief overview of how address generation works, for informational purposes:

0 - Having a private [[ECDSA]] key
18e14a7b6a307f426a94f8114701e7c8e774e7f9a47e2c2035db29a206321725
1 - Take the corresponding public key generated with it (33 bytes, 1 byte 0x02 (y-coord is even), and 32 bytes corresponding to X coordinate)
0250863ad64a87ae8a2fe83c1af1a8403cb53f53e486d8511dad8a04887e5b2352
2 - Perform [[SHA-256]] hashing on the public key
0b7c28c9b7290c98d7438e70b3d3f7c848fbd7d1dc194ff83f4f7cc9b1378e98
3 - Perform [[RIPEMD-160]] hashing on the result of SHA-256
f54a5851e9372b87810a8e60cdd2e7cfd80b6e31
4 - Add version byte in front of RIPEMD-160 hash (0x00 for Main Network)
00f54a5851e9372b87810a8e60cdd2e7cfd80b6e31
''(note that below steps are the [[Base58Check encoding]], which has multiple library options available implementing it)''<br>
5 - Perform SHA-256 hash on the extended RIPEMD-160 result
ad3c854da227c7e99c4abfad4ea41d71311160df2e415e713318c70d67c6b41c
6 - Perform SHA-256 hash on the result of the previous SHA-256 hash
c7f18fe8fcbed6396741e58ad259b5cb16b7fd7f041904147ba1dcffabf747fd
7 - Take the first 4 bytes of the second SHA-256 hash. This is the address checksum
c7f18fe8
8 - Add the 4 checksum bytes from stage 7 at the end of extended RIPEMD-160 hash from stage 4. This is the 25-byte binary Bitcoin Address.
00f54a5851e9372b87810a8e60cdd2e7cfd80b6e31c7f18fe8
9 - Convert the result from a byte string into a base58 string using [[Base58Check encoding]]. This is the most commonly used Bitcoin Address format
