Bech32 adoption

2018-07-16T18:17:05Z

Greenaddress: updated greenaddress to Yes for "Send to" and Planned for "Create/Receive"

[[Bech32]] is a new bitcoin [[address]] format specified by [[BIP 0173]]. This page tracks the adoption of [[Bech32]].

Ideally wallets would first support ''sending to'' bech32 addresses. After almost every wallet can send then people may be willing to adopt bech32 widely for receiving.

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

=== Blockchain Explorers ===

For trying these out you can use mainnet TXIDs <code>4ef47f6eb681d5d9fa2f7e16336cd629303c635e8da51e425b76088be9c8744c</code> and <code>514a33f1d46179b89e1fea7bbb07b682ab14083a276979f91038369d1a8d689b</code>. And 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.

Green address

2014-06-25T19:00:16Z

Greenaddress:

'''GreenAddress''' is also the name used by a [http://bitcoin.stackexchange.com/questions/3718/what-are-multi-signature-transactions multisignature] and [https://github.com/greenaddress/bips/blob/bip-payment-request-instant-confirmations/bip-payment-request-instant-confirmations.mediawiki instant/zeroconf] wallet service, for more details see [https://greenaddress.it GreenAddress].
''Note'': the service does not use the mechanism described below.

'''Green addresses''' was a proposed use of special trusted ECDSA keypairs that to indicate the origin of funds to a recipient.
Assuming the recipient trusts the operator of the keypair to not attempt a [[Double-spending|double spend]], the recipient may treat the funds as confirmed the moment they arrive.
'''This proposal is generally considered a bad idea and not advisable to implement.'''

As an example, assume website Z accepts incoming Bitcoin payments, but also trusts the green address published by [[Mt. Gox]].
Customer C wants to withdraw funds from Mt. Gox and send them to a payment address of website Z.
A customer who does a withdrawal from Mt. Gox could click the ''use green address'' checkbox, which will result in the payment being sent to the "green address" derived from the special keypair as an intermediate step before forwarding the payment to site Z.
Site Z can confirm that the payment passed through Mt. Gox's keypair and trust the payment as confirmed immediately, since it knows that the only party who could potentially perform an attack to reverse the payment is Mt. Gox.

The concept originated on the Bitcoin Talk forum in 2011 and was discussed in two threads<ref>https://bitcointalk.org/index.php?topic=48170</ref><ref>https://bitcointalk.org/index.php?topic=32818.0</ref>.
Since then, it was implemented by [[Instawallet]] and [[Mt. Gox]], both of which have since been compromised and closed.

==Criticism==
===Confusion between wallet/controller and owner===
Bitcoin signatures do not infer any particular legal origin of bitcoins, and when the signature is used to imply some origin, it seems to infer this myth.

===Blockchain spam===
In order to actually use green addresses, it is necessary to create an extra transaction to the special ECDSA keypair before then forwarding it on to its final destination.

==Overview==

This table compares the features of the different clients. All of the listed clients are open-source.

===Feature key===

; Wallet Security : How well the client protects your [[private key]]s from people with access to the machine the wallet is stored on. The private keys can be encrypted, for example. The private keys can also be either stored on your device or on a remote server.
; Network Security : Clients which more fully implement the Bitcoin network protocol are safer -- they can't be as easily tricked by powerful attackers. A client which ''fully'' implements the protocol will always use the correct [[block chain]] and will never allow [[double-spending|double-spends]] or invalid transactions to exist in the block chain under any circumstances. Clients which only ''partially'' implement the protocol typically trust that 50% or more of the network's mining power is honest. Some clients trust one or more ''remote servers'' to protect them from double-spends and other network attacks.
; Setup Time : Some clients require that you download and verify a large amount of data before you can send or receive BTC.
; Maturity : When the project was started.

===Feature key===

; Wallet Security : How well the client protects your [[private key]]s from people with access to the machine the wallet is stored on. The private keys can be encrypted, for example. The private keys can also be either stored on your device or on a remote server.
; Network Security : Clients which more fully implement the Bitcoin network protocol are safer -- they can't be as easily tricked by powerful attackers. A client which ''fully'' implements the protocol will always use the correct [[block chain]] and will never allow [[double-spending|double-spends]] or invalid transactions to exist in the block chain under any circumstances. Clients which only ''partially'' implement the protocol typically trust that 50% or more of the network's mining power is honest. Some clients trust one or more ''remote servers'' to protect them from double-spends and other network attacks.
; Setup Time : Some clients require that you download and verify a large amount of data before you can send or receive BTC.
; Maturity : When the project was started.
