Codes below are atomic.py from the pyrlp package, which is a library of pyethereum.

Python 2 does not support the metaclass keyword argument to classes, and pyrlp dropped support for Python 2 in April 2018.

Use Python 3 instead.

QUESTION

What is the difference between py-evm and pythereum?

Asked 2018-May-29 at 09:49

I usually use geth or parity client but trying to use pythereum for vyper implementation.

But looks like two types of ethereum clients using python implementation which are :

https://github.com/ethereum/pyethereum

https://github.com/ethereum/py-evm

Also, there is another python client called pyethapp too. (https://github.com/ethereum/pyethapp)

So can anybody teach me the differences and which situation should I use which?

py-evm is the one actively developed and supported. Note that it's still in pre-alpha state. It's not ready for production use.

QUESTION

How to store "complex" data structure as a Persistent Data Structures using ethereum & serpent

Asked 2018-May-20 at 06:12

My work is concerning Smart Contract dev. using (py)ethereum and serpent,

When reading "A Programmer’s Guide to Ethereum and Serpent", I saw on point 5.9 that :

[...] Persistent data structures can be declared using the data declaration. This allows for the declaration of arrays and tuples. [...]

and:

[...] For simple storage, self.storage[] is useful, but for larger contracts, we recommend the use of data (unless you need a key- value storage, of course) [...]

Code example:

IMPORTANT : Please note that according to this Vitalik Tweet, Serpent is now an "outdated tech".

The Serpent README has been updated to :

Being a low-level language, Serpent is NOT RECOMMENDED for building applications unless you really really know what you're doing. The creator recommends Solidity as a default choice, LLL if you want close-to-the-metal optimizations, or Vyper if you like its features though it is still experimental.

If you want to code Ethereum contracts from Python in order to release a production product, start to think about to migrate to Solidity or Vyper (which is still a "New experimental programming language")

Concerning my question, I finaly found a (tricky/dirty) solution, which consist of encoding the complex data before pushing it to the persistant data storage, then decoding after retrieving data from the storage.

Please see updated code bellow:

I'm a bit unsure why you are using --force for linking, but first try everything without the force flag.

Second, I think you can ignore the linker warnings, because there is openssl already available and thus brew did not link the other installed version.

Finally, your last issue is due to missing certificates and pip does not know how to handle it. The workaround is to ignore the https by using --index-url and passing the http url as a parameter then set it as the --trusted-host source, i.e.,
