To fix this, I've written a proposal to have the common B-with-vertical-bars bitcoin symbol added to Unicode. I've successfully proposed a new character for Unicode before, so I'm familiar with the process and think this has a good chance of succeeding. The proposal is at http://righto.com/bitcoin-unicode.pdf

📝 Original message:Hey guys,
With all the recent congestion and discussion regarding FSS-RBF, I was wondering if there good reasons not to have CPFP as a default policy? Or is it?
I was also wondering, with CPFP, should the transaction fee be based on total transactions size, or the sum of each transaction’s required fee? For example, a third transaction C whose unconfirmed utxo from transaction B has an unconfirmed utxo in transaction A (all of A’s inputs are confirmed), with each A, B and C being ~300bytes, should C’s transaction fee be 0.0001 btc for the ~1kb it is about to commit to the blockchain, or 0.0003 btc for the 3 transactions it is going to commit.
I tried to test it out a few days ago, sending 0.0008 btc without any fee, then that utxo into another transaction w/ 0.0001 btc. It still hasn’t confirmed, which could be any of: a) CPFP doesn’t have enough hash power, b) the amounts are too small, c) the coins are too new, d) the fee should have actually been 0.0002 btc, e) the congestion is just too great; or some combination.
Just curious as whatnot…
Thanks,
RicMoo

📝 Original message:By ignored, do you mean the nodes/miners didn’t even include the low fee transaction in their memory pools, so would no longer have access to it? If a node decides to not include it in its memory pool for this reason, I guess it won’t send out any INV messages either?
Could the broadcaster of TX_b rebroadcast TX_a? Then I guess any node that did add it to its memory pool would realize it’s not new and not rebroadcast it to those who didn’t, so it won’t propagate… Although, after receiving the orphan transaction TX_b, it could re-(pay attention) to an INV with TX_a (for a short-ish time to prevent further DoS vectors)? Assuming the sender of TX_b has a copy of TX_a…

📝 Original message:Oh, I see. I misread, thinking you wanted the dev team to have a private key and share the public key, similar to alerts. But each peer would have a public/private key pair and use something akin to ECDH for a symmetric key and transport using a block cipher?
How would you share the public key? If I were a man-in-the-middle, I could intercept the public key, generate my own and pass that along and then decouple the pipe when the other side shares their public key.
Also, you should not ignore your SSH fingerprint, as you exactly open yourself to mitm attacks.

📝 Original message:Hey all,
I'm wondering if anyone can help explain to me tx 70f7c15c6f62139cc41afa858894650344eda9975b46656d893ee59df8914a3d...
(https://blockchain.info/tx/70f7c15c6f62139cc41afa858894650344eda9975b46656d893ee59df8914a3d)
The input signature script is:
304402206b5c3b1c86748dcf328b9f3a65e10085afcf5d1af5b40970d8ce3a9355e06b5b0220cdbdc23e6d3618e47056fccc60c5f73d1a542186705197e5791e97f0e6582a3201
Which decodes to:
r= 48560432700441876832361368709121298776045893858160378595187765610521057848155

The ECC library I'm using is failing to verify this, which I think makes sense, since I the point needs to be positive, no? But it is obviously valid, as it has been verified and spent. I have tried simply modulo curve.order to positive-ify it, but that didn't seem to work either. Given a point P (with Py < 0) is there some fancy way to bring it into the elliptic curve space, such that Px >= 0 and Py >= 0?
Thanks!
