There are different ways to connect to blockchain:

  1. RPC data provider or other API: in most cases, you have to rely on its stability and security.
  2. ADNL connection: you're connecting to a liteserver. They might be inaccessible, but with a certain level of validation (implemented in the library), cannot lie.
  3. Tonlib binary: you're connecting to liteserver as well, so all benefits and downsides apply, but your application also contains a dynamic-loading library compiled outside.
  4. Offchain-only. Such SDKs allow to create and serialize cells, which you can then send to APIs.
