📝 Original message:We integrated libconsensus into bits of proof. It works well, in-line for all test cases with our Java engine and is about 50% faster on a single thread.
The performance advantage unfortunatelly reverses if libconsensus is executed on several threads simultaneously as we do with the Java engine, since an error:
Assertion failed: (pkey != NULL), function CECKey, file ecwrapper.cpp, line 96.
arises under that stress.
I guess that the cause is that thread callbacks as advised for OpenSSL on https://www.openssl.org/docs/crypto/threads.html are not registered.
Registering those however would require access to OpenSSL functions, not exported from the lib.
I’d be thankful for a pointer to a workaround.
