I agree completely.

I mean that for curves with cofactor==1, for every point that lies on the curve n*point will be infinity, thus that check can indeed be skipped.

Did you read the few posts above?

Make sure you have commit c7f039b67 (Process getdata invs separately until send buffer overflows), though there are a few other commits that improve memory consumption recently.

I think you are right. The check for verifying whether multiplying by the order ended up at infinity is part of the algorithm specified in the SEC specification, but is actually mathematically trivial for curves with cofactor=1 (which is the case for secp256k1).

Hello everyone,

as some may know, Bitcoin uses DER-encoded signatures in its transactions. However, OpenSSL (which is used to verify them) accepts more than just the strict DER specification (it allows negative numbers, extra zero padding, extra bytes at the end, and perhaps more). As we don't like the de-facto specification of the Bitcoin block validity rules to depend on OpenSSL, we're trying to introduce a rule to make such non-standard signatures invalid. Obviously, that can't be done as long as any significant amount of clients on the network is creating these.

I've monitored all transactions the past weeks (1.4M transactions), and it seems 9641 of them contain at least one non-standard signature. Below is a list of the top 150 addresses that had coins used as inputs in such transactions, sorted by frequency. If you recognize any of these addresses, or have an idea of who owns them or what software they are using, please let me know. Thanks!

It was in 0.8.0's release notes

Block 226035 affected 3343 distinct transactions, which is high, but far from the presumed tipping point of 0.7 and earlier (assumed to be around 4800).

Perfectly safe.

And now a more elaborate explanation:

0.7 and older nodes use BDB for storing the blockchain databases. It seems this database has a limit on the size of the modification it can make atomically to the database. With the larger blocks of the past days, it seems to have triggered the limit. The result is that 0.7 (by default, it can be tweaked manually) will not accept "too large" blocks (we don't yet know what exactly causes it, but it is very likely caused by many transactions in the block). Specifically, block
000000000000015c50b165fcdd33556f8b44800c5298943ac70b112df480c023 (height=225430) with >1700 transactions.

However. 0.8 (which uses a different database system) has no such limit, and happily accepts the block. As the majority of the hash power was on 0.8, the longest chain ended up using this block, which is not accepted by older nodes.

The solution is to (for now) go back to the old chain, which has block 00000000000001c108384350f74090433e7fcf79a606b8e797f065b130575932 at height 225430.

Hello everyone,

there is an emergency right now: the block chain has split between 0.7+earlier and 0.8 nodes. I'll explain the reasons in a minute, but this is what you need to know now:

• After a discussion on #bitcoin-dev, it seems trying to get everyone on the old chain again is the least risky solution.
• If you're a miner, please do not mine on 0.8 code. Stop, or switch back to 0.7. BTCGuild is switching to 0.7, so the old chain will get a majority hash rate soon.
• If you're a merchant: please stop processing transactions until the chains converge.
• If you're on 0.7 or older, the client will likely tell you that you need to upgrade. Do not follow this advise - the warning should go away as soon as the old chain catches up.
• If you are not a merchant or a miner, don't worry.

I would personally very much like to limit the number of variations we need to consider. You are right that there are security risks when a user can obtain a parent extended public key, and a child secret key, but I do not see a way to avoid this, except by dropping the ability to do public derivation. However, when client software does not expose a chain code ever, the whole sceme is effectively type-1, in the sens that it derives private data from private data (and knowing the public key gives you 0 information about the child key); it's a weirdly complicated randomization function, but it still is one.

Now for the encryption case: I envisioned chain codes as not being encrypted, as that prevents the wallet from functioning without decryption whatsoever (as opposed to just decrypting private keys when needing to do a spend). This does mean that if someone who got a child private key from you is able to steal a parent chain code, you are fucked. My only answer to this right now, is that giving someone a private key already implies a degree of trust (you're sharing private keys, so you're sharing the ability to spend the same coins). However, if you trust them enough not to steal your wallet, why not trust them with the keys in the first place.

Regarding using addition instead of multiplication: we switched to multiplication at some point, but I can't remember why - the only thing it adds is removing the ability to compute I_L from a parent and a child pubkey, which doesn't seem to gain you anything.

I want to stress that BIP32 isn't final yet, so please don't release code that implements it.

If there is need to make changes still, I really want to avoid several different revisions in the wild.

I'll post test vectors in the BIP document as soon as I feel confident things won't change anymore.

Since 0.8.0 final is released, I'd like to thank everyone who participated in testing the pre-release versions. Several problems were found after user reports, and others at least showed that many people noticed the improvements. There is certainly still room for improvement, but we're making progress in small (and sometimes bigger) steps.

Thanks!

Nothing, but you've kicked yourself off the network (until a majority of mining power + a significant amount of full nodes on the network implement your rule too.

Correct.

Technically, you don't even need to wait for the reindex to complete (as reindexing uses the block files in blocks/blk* to build chainstate and blocks/index).
