Re: [bitcoin-dev] BIP Number Request: Addresses over Audio

I started work on the decoder. It works by comparing each cycle of the sine wave recorded with a certain frequency (freq_t). The function that does this currently returns the last sample that falls in that range over all samples. The longest chain to match up with a certain frequency the best is

Re: [bitcoin-dev] BIP Number Request: Addresses over Audio

For reasons others have pointed out, it's not really plausible. Either way, this has nothing to do with transmitting data over audio. Please start a new thread if you want to discuss your idea instead of hijacking this one. Thanks ;) On Fri, Aug 12, 2016, 05:36 Erik Aronesty via bitcoin-dev <

Re: [bitcoin-dev] BIP Number Request: Addresses over Audio

No, anyone with the bip32 public seed can do the same as the receiver as "watch only". The only difference is rhat the receiver can actually spend the coins. As gmaxwell explained, if it's expensive for everyone, it will be also expensive for the receiver (assuming no interaction after the bip32

Re: [bitcoin-dev] BIP Number Request: Addresses over Audio

I'm imagining a "publishable seed" such that: - someone can derive a random bitcoin address from it - and send funds to it. - the possible derived address space is large enough that generating all possible addresses would be a barrier - the receiver, however, knowing the private key, can

Re: [bitcoin-dev] BIP Number Request: Addresses over Audio

Can't have shared secrets or interactivity for a public address to have the love it needs. Still not sure how you can take a BIP32 public seed and figure out if an address was derived from it though. I mean, wouldn't I have to compute all 2^31 possible public child addresses? On Thu, Aug

Re: [bitcoin-dev] BIP Number Request: Addresses over Audio

Sorr, I thought there was some BIP for a public seed such that someone can generate new random addresses, but cannot trivially verify whether an address was derived from the seed. On Wed, Aug 10, 2016 at 1:38 PM, Pieter Wuille wrote: > On Wed, Aug 10, 2016 at 7:28 PM,

Re: [bitcoin-dev] BIP Number Request: Addresses over Audio

I agree, audio-based transference isn't really great for a podcast or radio ad. It could be used to transmit payment details between phones that don't have cameras, though. I think it would be better to define a standard for transmitting information over audio, but not define what information is

By sending a public seed, there's no way for someone to use the transmitted address and trace the total amount of payments to it. On Aug 10, 2016 12:02 PM, "Daniel Hoffman via bitcoin-dev" < bitcoin-dev@lists.linuxfoundation.org> wrote: > Erik > What would be the advantages of transmitting a

Erik What would be the advantages of transmitting a BIP32 public seed, instead of a plain address? Theo I didn't really think of that, but that's genius. On Wed, Aug 10, 2016 at 6:49 AM, Theo Chino via bitcoin-dev < bitcoin-dev@lists.linuxfoundation.org> wrote: > Another use for the audio would

Another use for the audio would be for watches that can listen but can't use a camera (ie: Samsung S2), so sound would be great. On Wed, Aug 10, 2016 at 7:42 AM, Erik Aronesty via bitcoin-dev < bitcoin-dev@lists.linuxfoundation.org> wrote: > NOTE: > > Addresses aren't really meant to be

Re: [bitcoin-dev] BIP Number Request: Addresses over Audio

Have you considered CDMA? This has the nice property that it just sounds like noise. The codes would take longer to send, but you could send multiple bits at once and have the codes orthogonal. ___ bitcoin-dev mailing list

Re: [bitcoin-dev] BIP Number Request: Addresses over Audio

Wow. No value judgement, but 1980 called, they want their radio broadcast for analogue modems back. Both very cool and very cringe worthy. It sounds quite horrible tbh. Imagine this being as pervasive as bar and qr codes. And it's as meaningful and unpleasant to the human ear as a qr code is to

Re: [bitcoin-dev] BIP Number Request: Addresses over Audio

If this is just encoding BIP-21 addresses, it is basically an "audio QR code". In this case, does publishing it as a BIP still make sense? (Not to imply that it doesn't, but it's something you should consider.) Please look at existing implementations of audio modems when creating your design. A

I wouldn't worry about payment requests until I built a decoder and made the transmission a lot faster (probably adding tones and making it 5 bits wide), which shouldn't be hard On Mon, Aug 8, 2016 at 5:06 PM, Justin Newton via bitcoin-dev < bitcoin-dev@lists.linuxfoundation.org> wrote: >

Re: [bitcoin-dev] BIP Number Request: Addresses over Audio

Would it be feasible to transmit an entire BIP21 URI as audio? If you were to encode any extra information (such as amount), it would be useful to include a checksum for the entire message. This checksum could possibly be used instead of the checksum in the address. Trevin On Aug 8, 2016 3:06
