Electrum
Summary
Section titled “Summary”MoreBC2 has current read-only Electrum observations for BitcoinII infrastructure from 2026-09-11.
Canonical current evidence: Public infrastructure smoke test — 2026-09-11.
The older July smoke test remains historical evidence but is no longer the primary current reference.
Current observed endpoints
Section titled “Current observed endpoints”| Endpoint | Status at 2026-09-11 check | Evidence |
|---|---|---|
tcp://infra1.bitcoin-ii.org:50008 |
Connected; server.version succeeded. |
September infrastructure smoke test |
ssl://infra1.bitcoin-ii.org:50009 |
Connected over TLS 1.3; hostname validation succeeded; server.version succeeded. |

tcp://explorer.bitcoin-ii.org:5008 |
Timed out again. | September infrastructure smoke test |
Observed protocol details
Section titled “Observed protocol details”For the working infra1.bitcoin-ii.org endpoints, the September check observed:
- server software:
ElectrumX 1.18.0 - protocol:
1.4 - TLS 1.3 on the SSL endpoint
- certificate hostname validation succeeded for
infra1.bitcoin-ii.org - certificate expiry observed by the client: 2026-11-20
Earlier testing also observed the BitcoinII genesis hash through Electrum metadata:
0000000028f062b221c1a8a5cf0244b1627315f7aa5b775b931cfec46dc17cebWhat was and was not exercised
Section titled “What was and was not exercised”The current September recheck established protocol reachability through server.version and TLS behavior.
Earlier July testing additionally used:
server.featuresblockchain.headers.subscribe
No MoreBC2 record currently establishes:
- wallet-history correctness,
- address/scripthash history correctness,
- watch-only wallet behavior,
- fee behavior inside third-party wallets,
- transaction construction,
- successful Electrum transaction broadcast,
- long-running subscriptions,
- reconnect/load behavior,
- BlueWallet, Cake Wallet, Komodo Wallet, or other third-party wallet compatibility.
Current endpoint guidance
Section titled “Current endpoint guidance”Use infra1.bitcoin-ii.org:50008 and :50009 only as dated observed Electrum service endpoints.
Do not publish explorer.bitcoin-ii.org:5008 as a working current endpoint; it timed out in both the historical and current checks.
Electrum connectivity should not be presented as proof that a specific wallet safely supports BC2.
Verification
Section titled “Verification”Status: Draft / Observed partial
Primary source checked: Public infrastructure smoke test — 2026-09-11
Notes: Current read-only TCP/TLS reachability is established. Wallet compatibility, history semantics, spending behavior, and Electrum broadcast remain unverified.
