(Jim Posen) Pull request description: This implements the compact block filter construction in [BIP 158](https://github.com/bitcoin/bips/blob/master/bip-0158.mediawiki). The code is not used anywhere in the Bitcoin Core code base yet. The next step towards [BIP 157](https://github.com/bitcoin/bips/blob/master/bip-0157.mediawiki) support would be to create an indexing module similar to `TxIndex` that constructs the basic and extended filters for each validated block. ### Filter Sizes [Here](https://gateway.ipfs.io/ipfs/QmRqaAAQZ5ZX5eqxP7J2R1MzFrc2WDdKSWJEKtQzyawqog) is a CSV of filter sizes for blocks in the main chain. As you can see below, the ratio of filter size to block size drops after the first ~150,000 blocks: ![filter_sizes](https://user-images.githubusercontent.com/881253/42900589-299772d4-8a7e-11e8-886d-0d4f3f4fbe44.png) The reason for the relatively large filter sizes is that Golomb-coded sets only achieve good compression with a sufficient number of elements. Empirically, the average element size with 100 elements is 14% larger than with 10,000 elements. The ratio of filter size to block size is computed without witness data for basic filters. Here is a summary table of filter size ratios *for blocks after height 150,000*: | Stat | Filter Type | |-------|--------------| | Weighted Size Ratio Mean | 0.0198 | | Size Ratio Mean | 0.0224 | | Size Ratio Std Deviation | 0.0202 | | Mean Element Size (bits) | 21.145 | | Approx Theoretical Min Element Size (bits) | 21.025 | Tree-SHA512: 2d045fbfc3fc45490ecb9b08d2f7e4dbbe7cd8c1c939f06bbdb8e8aacfe4c495cdb67c820e52520baebbf8a8305a0efd8e59d3fa8e367574a4b830509a39223f

6ad0328f1c Don't assert(foo()) where foo has side effects (practicalswift) Pull request description: Don't `assert(foo())` where `foo` has side effects. From `assert(3)`: > If the macro `NDEBUG` is defined at the moment `<assert.h>` was last included, the macro `assert()` generates no code, and hence does nothing at all. Bitcoin currently cannot be compiled without assertions, but we shouldn't rely on that.

This results in signatures that are always less than 71 bytes (32 byte R + 32 byte S + 6 bytes DER + 1 byte sighash) with low R values. In most cases, the signature will be 71 bytes. Because R is not mutable in the same way that S is, a low R value can only be found by trying different nonces. RFC 6979 for deterministic nonce generation has the option to specify additional entropy, so we simply use that and add a uin32_t counter which we increment in order to try different nonces. Nonces are sill deterministically generated as the nonce used will the be the first one where the counter results in a nonce that results in a low R value. Because different nonces need to be tried, time to produce a signature does increase. On average, it takes twice as long to make a signature as two signatures need to be created, on average, to find one with a low R. Having a fixed size signature makes size calculations easier and also saves half a byte of transaction size, on average. DUMMY_SIGNATURE_CREATOR has been modified to produce 71 byte dummy signatures instead of 72 byte signatures.

2018-08-09Always create 70 byte signatures with low R valuesAndrew Chow
When extra entropy is not specified by the caller, CKey::Sign will now always create a signature that has a low R value and is at most 70 bytes. The resulting signature on the stack will be 71 bytes when the sighash byte is included. Using low R signatures means that the resulting DER encoded signature will never need to have additional padding to account for high R values.

fa5ed4f8d2 refactor: Avoid locking tx pool cs thrice (MarcoFalke) Pull request description: `addUnchecked` is (outside the tests) only called by ATMP, which already takes the tx pool read lock. So locking it twice more in both `addUnchecked` methods seems redundant. Similarly `CalculateMemPoolAncestors` is (beside once in the wallet) only called in contexts, where the tx pool lock is already taken. So remove the lock there as well.
