This time it is about a cipher that is/will be used in the new tinc protocol: ECDSA According to https://github.com/gsliepen/tinc/blob/1.1/src/openssl/ecdsagen.c you use the secp521r1 curve, which is derived (according to http://www.secg.org/collateral/sec2_final.pdf - page 18) from the seed value "D09E8800 291CB853 96CC6717 393284AA A0DA64BA".
