Today, we built a private chain and dug and transferred funds, made a simple record, and wrote a detailed tutorial tomorrow. 1, mkdir Private-geth CD Private-geth Create a new TXT within the folder and enter the following code: {"Coinbase": "0x0000000000000000000000000000000000000000","Config": {"Homesteadblock": 5},"Difficulty": "0x20000","Extradata": "0x","Gaslimit": "0x2fefd8","Mixhash": "0x00000000000000000000000000000000000000647572616c6578736564

Knowing these nouns is a good place to start: Public key cryptography System. Alice has a public key and a private key. She can create a digital signature with her private key, and Bob can use her public key to verify that the signature was actually created with Alice's private key, that is, Alice's signature. When you create a digital currency or Bitcoin wallet, that long 0xdf ... The 5f address is essentially a public key, and the corresponding private key is saved somewhere. An online wall

transaction. Each txin is associated to a witness field. The witness field starts with Var_int, and the Var_int value represents the number of stacks that the txin needs to occupy, followed by the stack's member values. Each stack member begins with Var_int. Witness data is not a script or a 520-byte compression stack limit. A non-witness txin must be associated with an empty witness field, represented as 0x00. If all txin do not have a witness program, then the transaction must be serialized

and public key is compressed information, the early virtual currency developers did not know that the generated public key can be compressed, The compressed public key has only 33 bytes, and the uncompressed public key has 65 bytes. The compressed public key is more meaningful to the virtual currency, because the virtual currency is a centralized, peer-to-coinbase crypto currency, each node will have a complete transaction record, each transaction wi

easier to get started with Ethereum, smart contracts, and build dapps (decentralized apps, distributed applications). I will try to explain in my own (still novice) understanding what each step of the workflow is doing, and I get a lot of help from Consensys's cool developers. Basic Concepts Knowing these nouns is a good place to start: Public key cryptography System. Alice has a public key and a private key.
