- Gradecoin
- A block that was proposed to commit Transactions in transaction_list to the
-ledger with a nonce that made hash valid; 6 zeroes at the left hand side of the
-hash (24 bytes).
We are mining using blake2s algorithm, which produces 256 bit hashes. Hash/second is roughly 20x103 on my machine, a new block can be mined in around 4-6 minutes.
-Requests
-GET
-A HTTP GET request to /block endpoint will return the latest mined block.
POST
-A HTTP POST request with Authorization using JWT will allow you to propose your own blocks.
Fields
-
-transaction_list: [array of Fingerprints]
-nonce: unsigned 32-bit integer
-timestamp: ISO 8601 <date>T<time>
-hash: String
-Mining
-The mining process for the hash involves;
--
-
- Creating a temporary JSON object with
transaction_list,timestampandnoncevalues
- - Serializing it -
- Calculating blake2s hash of the serialized string -
If the resulting hash is valid, then you can create a Block JSON object with the found nonce and hash.
Hash
-tha field in jwt documentation in fact stands for "The Hash", in the case of a post request for a block, you need to use hash field of the block.
