The Constantinople fork is now set to be implemented at block 7,280,000 and will be a “single fork on mainnet and a post-Constantinople-fixup fork on the testnets to get them back in line feature wise with the main network.” The upgrade was initially scheduled for January 16, 2019, but was canceled the night before after receiving reports for vulnerabilities that might leave it open to a possible “reentrancy attack.”

The Ripple company token was hovering around the $0.335 level at the end of last week. As mentioned in BTCManager’s Weekly Market Outlook, the $0.335 to $0.34 zone proved to be a strong support/resistance line in August 2018. Now it also coincides with the Fibonacci 50 percent retracement level, which makes it extremely important for further movements.

Ripple reported that the software libraries published before August 2015 rendered private keys which signed multiple transactions vulnerable. According to the announcement, it is not an issue with the XRP ledger but with improperly made ECDSA (Elliptic Curve Digital Signature Algorithms) signatures. The vulnerability comes from defects in signing software that does not properly use unbiased (random or deterministic but apparently random) nonces.
The vulnerability was initially discovered by the DFINITY Foundation and the University of California, which also claimed they have successfully hacked some Bitcoin, Ethereum, and Ripple addresses with the old configuration. The issue, however, has been fixed in the default Bitcoin, Ethereum, and XRP libraries after August 2015 by implementing deterministic ECDSA nonce generation.
