Technical Progress
Ulord
1. Feiteng processor openss and botan for hash algorithm support was tested. The preliminary test shows that openssl has a better performance than botan. Next, the research staff will track and debug whether botan uses armv8 crypto instructions to ensure the security of data on the chain;
2. Botan. sha2_32_armv8.cpp using the sha256 instruction in crypto was tested, and by calling the built-in function, the test shows that the speed is still slower than openssl;
3. The performance instructions were tested to ensure the smooth running of the chain.
UDFS
The efficiency of dispatcher IP address recognition was modified to improve the running efficiency of the chain.
Operation Progress
Ulord Chain Cloud Ecosystem News brings the latest blockchain information.
Product Progress
The UDFS reward distribution was optimized to solve the users’ problem.
Terminology
Hash: an input of any length (also known as a pre-mapped pre-image) and transforms it through a hashing algorithm into an output of a fixed length, which is the hash value.This transformation is a compression mapping, that is, the space of the hash value is usually much smaller than the space of the input. Different inputs may be hashed into the same output, so it is not possible to determine a unique input value from the hash value. Simply speaking, it is a function that compresses a message of any length into a message digest of a fixed length.
