On fresh checkout, "make check" after cmake fails because the directory "test/data" doesn't exists (at least on my config; I am a bit new to cmake):

• Use simplified serialization (4b height + 1b iscoinbase)
• Use boost::noncopyable

Lookg good

Ref D1474

Use CompactSize instead of VARINT

Rebasing to master and minor fixes from review at Bitcoin XT

Revert to signed chars for serialization

Thread safe context initialization and various small fixes

nothing wrong with the diff, but wasn't secp256k1 handled as a subtree? is this changed since @tomtomtom7's utxo commitments patches?

Minor fix in comments

Add another RPC test, fix up some comments.

Include third testvector in RPC test

Changed testvector 3 input and output

This is no integrated in D1074

Add first RPC test for UTXO commitment

Fix several logic errors and add commitment_calculated to the gettxoutsetinfo

Add testvector test for empty set

Empty update to reflect changes in D1072

Return 0 instead of SHA(0) for the empty multiset

No changes; just moved some stuff to previous diff for clarity

Change combining constructor to add method

Fix some logic error from the previous diff to D1117

Small refactoring to make it more clear

Still WIP, But much better version.

Fix compile error in serialize methods

Add (de)serialialization methods

Change the combine constructor to an Add method.

This still needs to build with cmake.

• Fixed braces
• Removed static from bench
• Reordered references in readme

As a general comment, I am a bit juggling with the proper integration via CCoinViews. This may mean we need more changes to this wrapper class.

Updated to try a more efficient approach with batching the delta

Include Clear() method

Add cmake configuration

Fix in cmake file for multiset module

Enable multiset module in cmake configuration

Add cmake switch for multiset module

Add test vectors as included in the specification

• Better align comment/indent styling
• Fix test-failing typo in new hash-to-EC-point algorithm
• Clarify reference to PDF as source of ECMH algorithm
• Add more test comments
• Add duplicate element tests

Using suggested trial-and-hash algorithm with incrementing prefix

I am a bit uncertain about finalize. Is there actually a point in hashing?

I have address some of the issues

Addressing some of the review comments

Split CUtxoCommit in header and source file

I am sorry for leaving this on table, but I must say I am bit disappointed about the procedure here.
