Eric Rykwalder is a software engineer and one of Chain.com s founders. Here, he gives an overview of the mathematical foundations of the bitcoin protocol. One reason bitcoin can be confusing for beginners is that the technology behind it redefines the concept of ownership. To own something in the traditional sense, be Updated news about bitcoin and all cryptocurrencies. Zero-Knowledge Proofs: A Layman’s Introduction. Alex has dedicated more of his time to create an article where he is giving an introduction to what ZK-SNARKs are. We encourage you to have a read and leave a comment if you find it useful. For the past months, I’ve been immersed daily in a thrilling and cutting-edge world: that of Zero ... An ECC (ECDSA, ECDH, ECMQV, etc) key is always relative to some 'curve' (more exactly, prime-order subgroup over a curve with an identified generator aka base point). For bitcoin this is secp256k1, but your question doesn't say it's limited to bitcoin and this answer would require modification for other applications using other curves. I created a EC key pair using "secp256r1" curve. It is 256-bit curve and private key should be 256 bits (32 bytes). But what I'm getting is 39 bytes private key. Here is my code This is one of the parameters of elliptic curve. The secp256k1 curve used in bitcoin have parameter N set to: N = FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFE BAAEDCE6 AF48A03B BFD25E8C D0364141
