pytoniq 0.0.5

TON Blockchain SDK

pytoniq

Pytoniq is a Python SDK for the TON Blockchain. Currently, it has native ADNL over TCP connection to Liteservers, boc types implementation, wrappers for almost all TLB schemes from block.tlb, automaic TL schemes serialization/deserialization, some popular contracts wrappers.

Examples

You can find them in the examples folder.

Blockstore

The library can prove all data it receives from a Liteserver (Learn about trust levels here). If you want to use LiteClient with the zero trust level, at the first time run library will prove block link from the init_block to the last masterchain block. Last proved blocks will be stored in the .blockstore folder. The file data contains ttl and gen_utime of the last synced key block, its data serialized according to the BlockIdExt TL scheme (but in big–endian), last synced masterchain block data. Filename is first 88 bytes of data described above with init block hash.
