1. Each shard is sorted, easy to merge when doing matching.
2. each block only update one shard (versus if shard using hash, probably every shard needs to be updated).

And if he receives a higher priority block proposal, he simply don't broadcast his own proposal.

Tested on AMD Threadripper 1950x (3.5 GHz) with single thread code.

Signature Verification

BLS signature (used for both consensus system and user transaction signing, user transaction signing can be switched to ESCDA):

5 seconds: 11500 verifications.

ESCDA (https://github.com/ethereum/go-ethereum/tree/master/crypto):

5 seconds: 41000 verifications.

Matching Engine

Single order book, 5 seconds: 10000000 limit orders

Conclution

Matching Engine is two orders of magnitude faster than signature verification.

Code:

Dev machine is too powerful, check test performance on macbook just in case.

Goal:

A DEX blockchain that is low-latency and high-throughput.

Week 6/11: finish everything, robust.

• test result
• complete all required features
• persist data on db
• sync
• ICO if have time

Week 6/18:

• finish scaling up by partition txn submission by account multiple broker groups and a single notary group. The final notary group can sort the orders using the permutation derived from the random beacon and len(orders) (which block proposers do not know) to prevent front-running.
• Updated test result

Week 6/25:

• documentation: white paper, design rationals, tutorials (e.g., how to use different tools under cmd/)
• code clean up
• pre-built binaries, docker images for building and running
• license (probably need LGPLv3) and double check dependencies' licenses.

Required features:

• sending and receiving of the native coin
• new token creation
• sending, receiving tokens
• freeze token
• burn token (adjust token total supply too)
• ability to trade one token with another token (all within the same chain)
  • limit orders and matching
  • expire orders according to block height
• execution report
• charge fee: "As network resources are required to process each order, a fee will apply. The order fee will be dynamically adjust based on how busy the network is, similar to other network fees". Fee events: token transfer, order submission, order cancellation, trade event, ICO.

Bonus feature:

• native on-chain ICO
• IOC order (order expires at the same height as the recorded height)
• FOK order
• market order

Can start with validating the entire random beacon, and download the latest history, verify it's signed by the correct group, and trust it.

Next step can be download recent state (e.g., 1000 blocks ago) and replay recent history. This won't be much safer though.

rlp does not optimize for encoding zero-valued fields (e.g., zero-valued byte array). Using a pointer would reduce encoded size for the nil byte array case.

We are optimistic that some day, there will be excellent fully decentralized exchanges. We intend to sponsor academia and support multiple projects in this space. Exchanges need to be fast, scalable and avoid problems such as order book front-running. For the time being, most decentralized exchanges demonstrate weaknesses one at least one of these factors. Some hybrid models are attempting to get the best of both world. Over time there will be better, more decentralized exchanges available. - rambo1stbld https://www.reddit.com/r/IAmA/comments/8p456q/we_are_binance_labs_a_blockchain_technology/e08cvi4/

Opinions are mine, not those of Binance Labs: I believe the biggest innovation in near term happens in the protocol level, as the change blockchain brings is more of a structural/horizontal change. But there are certain issues we need to solve for this innovation, including Scalability, Decentralization, Privacy, Security and Compliance. We are looking for projects who are solving the scalability issue without sacrificing interoperability, achieving decentralization while ensuring efficiency, preserving privacy while not compromising transparency, enhancing security while promoting usability and being compliant. - christychoi https://www.reddit.com/r/IAmA/comments/8p456q/we_are_binance_labs_a_blockchain_technology/e08ehdc/

Some promising hybrid exchanges are testing decentralized custody combined with centralized order books. I came across one project that was attempting the reverse. This space is evolving very rapidly and I look forward to learning about creative solutions for improving the crypto market's efficiency. - rambo1stbld https://www.reddit.com/r/IAmA/comments/8p456q/we_are_binance_labs_a_blockchain_technology/e08irq9/
