- Tokenview - Inaccessible.
- Bitcoinchain - No longer being maintained [last block height shows 614926, while we're at 749576].
- Blockexplorer.com - I don't think it has anything to do with Bitcoin +it's also outdated.
Many thanks again for your research.
So far, it's only too look up a specific address, while tx hash / block number doesn't work. Empty addresses are also shown as "invalid".
Since we can only judge from a tx hash if an (sending) address is (nested) SegWit or Multisig, it wasn't possible for me to verify if it's a SegWit address or not. In your summary, you said "SegWit-Addresses (P2SH) identifyable?* - Yes". May I ask where you got it from?
Do you know if more than just addresses will be featured at some point?
