类SQL方式的Blockchain，很新颖有趣。
实现语言：C++
forked by: mysql-server
摘要描述：
Start your own blockchain with the following simple command:
CREATE TABLE blocks (
id INT,
previous_block_id INT) TYPE=innodb;
复制代码
Don't forget to generate the Genesis block! Everyone can feel like Satoshi in the private Blockchain world!
INSERT INTO blocks (id, previous_block_id) VALUES (42, NULL);
复制代码
Now you are free to create your own transactions, make coins appear out of thin air, send them to yourself or your friends, censor the transactions of your competitors and collect transaction fees that are actually worth your time.
