Technical Progress
The Development of the Public Blockchain
1. The support for the network access to calculation data was added in avalon to improve effectively the development efficiency;
2. The enclave server program was tested to better build a trusted library;
3. The enclave untrusted network was tested to obtain data to expand the source of data acquisition.
Program
1. The network interface of the untrusted environment was debugged to ensure the access to the untrusted network data;
2. A work order test network call was written to improve the debugging efficiency;
3. The elliptic curve “secp256k1” was used to generate a private key compatible with ETH to better protect the privacy of users in the Burrow network.
UDFS
1. The problem of slow node upload speed was optimized to ensure users a better experience;
2. The go SDK version was written for both server and client.
Operation Progress
Ulord Chain Cloud News was updated to share the latest blockchain information.
Product Progress
1. The formal environment of the distributed storage UDFS V0.4.5 boot node has been tested, and the node will be upgraded.
2. The distributed storage UDFS has added the support for large files, streaming media, https and other functions. You can download the first Chinese blockchain movie The Last Thieves. The file name of the downloaded file is the hash value. You need to change the file suffix to .MP4 to play normally.
Terminology
Elliptic curve algorithm
Elliptic curve: it refers to the plane curve determined by the Weierstrass equation. If F is a domain, ai ∈ F, i=1,2,…,6. The number even (x, y) satisfying Equation 1 is called the point of the elliptic curve E on the F domain. The F field can be a rational number field or a finite field GF(Pr). The elliptic curve is usually denoted by E. In addition to all points of curve E, a special point O called the point at infinity must be added. The elliptic curve secp256k1 is the key encryption technology of the blockchain.
