FYI, I'm gonna use temp dir for the db directory. I checked the fs info on my machine, and it was mounted on the disk (not tmpfs).
@majecty Done.

Current DEX protocols have solved problems wrt to the risk of accidentally losing users custody due to security breaches. But two big issues remain unsolved. 1) centralized listing/delisting processes and 2) front-running issues due to the decentralized and transparent nature.
I and @joojis designed a new protocol, named CodeChain DEX protocol, that solves both of these problems. CodeChain DEX has a delegation system that encourages stakeholders to list assets that are in great demand and delist assets that are in poor demand. In addition, CodeChain DEX adopts time-release cryptography and ID-based encryption to prevent front-running attacks. Our commit-reveal scheme does not require any interaction between the participants, allowing traders to send orders non-interactively to the network.
Here is the link for the proposal we've written. We're open to new suggestions and ideas. https://research.codechain.io/t/codechain-dex-protocol/30
@majecty As I remember correctly, I also implemented some code generating the merkle proof for the purpose of debugging.
I wrote three proposals for opcodes required for implementing Vault language. Please have a look and give some feedback:

@majecty I think you are seeking this code https://github.com/CodeChain-io/codechain/blob/master/util/merkle/src/triehash.rs
@foriequal0 I got this errors after merging this PR CodeChain-io/codechain-sdk-python#31. I add a commit fixing this to here CodeChain-io/codechain-sdk-python#28

I'm working on snapshot synchronization, and currently I'm checking the entire codebase to make sure that CodeChain works even if there are missing blocks/headers in the database.
It's such an hard and tedious work, so it'd be nice if someone let me know the parts that I can skip checking.
Please let me know if you have any information :)

@foriequal0 Both PR here https://github.com/CodeChain-io/codechain-sdk-python/pulls are ready to be merged.
I see. I should update the rustfmt version to 2019-10-13.
the rust team published an article on async/await :)
