cli: show timestamp of the block#3
Conversation
Merkle tree requires a full binary tree, which means the number of node is power of 2 and the level of the tree is log(N) instead of N/2. This patch duplicate the node to a power of 2 number and correct the level calculation. Besides it adds a test case with 6 nodes. Signed-off-by: Wei Yang <richard.weiyang@gmail.com>
The leading "zeroBytes" in address is b58Alphabet[0] instead of 0x00. Signed-off-by: Wei Yang <richard.weiyang@gmail.com>
We could only send money from our own wallet. If the parameter is not an address in our wallet, exit the program gracefully and show an error message.

Wow! Thanks for your commits! I'll review them on Saturday. |

Awesome! But I cannot make it a package, because it should be a standalone app. Also, the exploring commands are just for debugging/testing, so they shouldn't be a part of the codebase. And the HTML part shouldn't be in the main package as well. It can be a part of a web-server package, and there could be a 'web-server' CLI command that starts the server. And the server would use the blockchain and read data from it. Eventually, this could be a web-based interfaces for the blockchain, where one can see things happening on the node, as well as send/receive coins.
If you're going to make a web-interface, could you please submit it in a separate PR, so I could merge the important improvements and bug fixes of this PR? Thanks!

I'm afraid this is against the idea of the project: it should be a standalone app, not a package. Why did you decide to make this change?

sure, this is up to you. I just add it for my purpose.

hmm, actually, I am not comfortable with the GitHub pull request.
Since what I want you to take is the fix on Decoder and merkle tree, the #2 - #4 commit.
While GitHub automatically create the pull request with all my new commits on master branch.
How could I send a pull request just with dedicated commit? or you could pick up the one you want? or I have to make a clean master branch so that you can pull?

It's better to do this via 'html/template', and this should be a separate package, because it's not directly related to the logic of the blockchain.

Agree, I just learn go, so...

Not sure about this file and commands. Looks like its purpose is just to debug/test things.

yep, this is some cli commands which helps me to understand the blockchain:-)
