Can I use the same private key for Ethereum and Bitcoin? Yes, both cryptocoins use the same elliptic curve SECP256K1. Perhaps a better alternative is to use a BIP32 wallet. You have a master key that is not directly used for transactions, but it is used to derive child keys than can be used Secp256k1 submodule. The secp256k1 submodule provides a library for elliptic curve operations on the curve Secp256k1.. It has the exact same API than the version 4.x of the secp256k1 module from cryptocoinjs, with two added function to create private keys.. Creating private keys. Secp256k1 private keys need to be cryptographycally secure random numbers with certain caracteristics Ethereum uses the SECP256k1 curve. Using elliptic curve point manipulation, we can derive a value from the private key, which is not reversible. This way we can create signatures that are safe and..

- The constants used by most blockchains are set in the secp256k1 standard. Example shape of an Elliptic Curve Before blockchain, this elliptic curve standard was not common at all. In fact, most mainstream hardware vendors don't support hardware encryption for this curve
- Elliptic curve choices in Ethereum: secp256k1 vs Curve25519 The elliptic curve Curve25519 has very good properties in terms of implementation security and speed of digital signatures, as well as solid, well-tested libraries like NaCl for encryption and signatures
- Wikipedia : Secp256k1 Ethereum Answers : If the reserves are stored with a bank or some other third party, another vulnerability is counterparty risk. This boils down to the question: Does the entity really have the collateral it claims to have? This has been a question frequently posed to Tether, for instance, without clear answers. Tether has yet to provide a full open audit of its reserves
- I have never programmed Ruby but I know a little bit about Bitcoin and Ethereum signatures. I hope I can help you. A bitcoin signature consists of two parts: (r,s).An Ethereum signature consists of three parts: (v,r,s). The extra value v which is only one byte allows for the derivation of the public key from the signature. There are only four possible values of v so the code that you are.

**Ethereum's** state is a large data structure which holds not only all accounts and balances, (such as Keccak-256 hashes or **secp256k1** signatures). During execution, the EVM maintains a transient memory (as a word-addressed byte array), which does not persist between transactions. Contracts, however, do contain a Merkle Patricia storage trie (as a word-addressable word array), associated with. Ethereum uses the same elliptic curve, secp256k1, so the process to get the public key is identical in both cryptocurrencies. By applying the ECDSA to the private key, we get a 64-byte integer, which is two 32-byte integers that represent X and Y of the point on the elliptic curve, concatenated together

- Starting from a private key, a working functional example provides details for how an Ethereum address can be calculated from an uncompressed secp256k1 elliptic curve public key. This functional example made it clear the computation of an Ethereum address had to use the proper Keccak hashing function, quite different from the NIST SHA3 implementation
- To use existing Ethereum keys, the Casper VM needs to know that the key is a secp256k1 type. The Rust casper-client provides an example of how this works. Pre-pending the public key with a 02 indicates the key is a secp256k1 key. The following transaction sends 100 CSPR. The Rust casper-client requires the secret key to be in PEM format to send.
- X and Y coordinates are numbers modulo p, the field size, which is around 2^256 - 2^32 for secp256k1. The value r and s in the signature however are modulo n, the group order, which is around 2^256 - 2^128. When R.x is between n and p, r is reduced to R.x-n. Thus, if you have an r value below 2^128-2^32, there may be 2 valid R.x values.

To provide Ethereum integration for your mobile applications, the very first thing you should be interested in doing is account management. Although all current leading Ethereum implementations provide account management built in, it is ill advised to keep accounts in any location that is shared between multiple applications and/or multiple people. The same way you do not entrust your ISP (who. The signature algorithm and hash function of Ethereum are secp256k1 and keccak256. Once the code to create a keccak256 hash is deployed to Nervos, we have everything required to use Ethereum's. Ethereum addresses are composed of the prefix 0x, a common identifier for hexadecimal, concatenated with the rightmost 20 bytes of the Keccak-256 hash of the ECDSA public key (the curve used is the so-called secp256k1). In hexadecimal, 2 digits represent a byte, meaning addresses contain 40 hexadecimal digits, e.g. Part Three: Creating and Signing Ethereum Transactions. Transactions must be signed by a private key in order to hold any value. Since all digital assets are created from transactions, signatures.

After this, Ethereum public keys (128 characters / 64 bytes) are created using an algorithm called Elliptic Curve Digital Signature Algorithm (ECDSA). Ethereum uses secp256k1 to generate public keys. Public key is a point in this Elliptic curve algorithm. Please check this book to learn more about Public keys To know whether secp256k1 is suitable for this type of pairing application would take more investigation, but going by Craig's track record and researching some unique aspects of the secp256k1 curve it seems very plausible. Its also possible Craig just made a mistake and was wrong, but evidence points to otherwise. I would like to hear others more knowledgeable in the subject of cryptographic. If you want to obtain a Bitcoin address or Ethereum account, you generate a random 256-bit integer x. x is then your private key. Then you compute X= x•P using the parameters for the secp256k1 curve. X will be your public key. Your public key is safe to give out and cannot be used to determine your private key. If you hash your public key. Web3.js and ethers.js are JavaScript libraries that allow developers to interact with the Ethereum blockchain.
