True, I first thought to exclude them from the main explorer chain, but still preserve them, to show as an additional feature, kinda of what blockchain.info does. But, as you said, when syncing the bitcoin client receives no orphan blocks, so I will either need a very long running daemon, or some kind of patch on the current source. So I finally decided to just exclude them.

I see that happening the following way. I'm currently syncing at 0.5 sec intervals, so after every sync I check 101 blocks behind. If confirmations parameter returned by the daemon is -1, i'm removing all blocks ahead and the current one, reverting all transactions and addresses, and resyncing.

In my above strategy, I'm assuming that forks of orphans beyond 101 blocks will not happen, atleast not practically. If that's not the correct way to do that, I accept constructive criticism.

Hello Bitcointalk members, as it's apparent from the title, i need a reliable way to detect orphan blocks. I wrote a custom explorer, and it's running quite fast actually, but i need an explanation on how exactly i can detect orphans, and mark them as so.

What the longest chain fork due to orphan blocks is?
If on every block sync, i check the last 1000 blocks, is that enough to assume that every block beyond these 1000 is NOT an orphan?
Is the -1 confirmations the only way to detect them?

Hi, i'm in search for a developer who can write a simple, stable block explorer in NodeJS/PHP. Payment details are discussed in private! Features that MUST be implemented are:

- Recent blocks
- Recent transactions
- Address details
- Block details
- Transaction details
-API
- Connection count, Block number, Masternode count,
-Difficulty, Hashrate to be displayed at the index page as well as accessible throu API

Okay, give me some chat platform you use.

Hi, can we connect on Discord? DEV#3821

Where is your project defined as LumoCash?

Seems like a very interesting and well designed project! Good luck!

Let's connect and have a chat about it ? I think i might be able to cide it per your requirements.

Hello , i work on an interesting crypto related project , maybe you can try it out ? If you like it then we can work something out !
