neo-mamba 0.4.1

Python SDK for the NEO 3 blockchain

neo-mamba

This SDK intends to provide building blocks for Python developers to interact with the NEO blockchain as a means to lower the entry barrier.

It is a work in progress and thus you can expect that not all parts of the blockchain are supported. What is present should be functioning correctly unless explicitely mentioned (e.g. because they depend on structures not yet available).

Please report any issues on Github or submit ideas how to improve the SDK.

Roadmap

Over time the following components are expected to be implemented starting with the items in “SDK Core”. As we release versions and receive feedback components may be added or restructured. Some components may end up living in separate repositories but be included here by default (e.g. virtual machine implementations).

• Core (v0.1)

• Network (v0.1)

• Storage (v0.1)

• Virtual Machine

• Smart contracts (v0.4)

Up next: Preview 4 parity

Performance

neo-mamba syncs the network over 2 times faster than the official client neo-cli.

Performance was measured by letting each client sync the Preview 3 TestNet from an offline file up to block height 562379. Syncing was done without verifying the block witnesses (--noverify flag in neo-cli). Each client used LevelDB as storage backend, with no other additional plugins running. Each client was synced separately with no additional resource usage on the system. The test was performed on Ubuntu Linux 18.04 (as DOTNET’s ECC on OSX is very slow) on a i5-4670K with 16 GB ram.
