pcoinAbout this explorer

This is a block explorer for PCoin (PCN), an independent Layer-1 chain: its own genesis block, its own network, its own UTXO set. It is a fork of Bitcoin Core v29.4 with proof-of-work replaced by RandomX (CPU friendly, ASIC resistant) and the difficulty algorithm replaced by LWMA. Block ids are still double-SHA256; only the proof-of-work hash changed.

What this explorer is

A server-rendered page over an address index built by polling a PCoin node for getblock <hash> 3. Bitcoin Core has no address index of its own — the chainstate is a UTXO set keyed by outpoint with no reverse map from script to outpoints — so "what does this address hold" has to be answered outside the node.

• It is read-only and non-custodial. It never generates an address, never holds a key, never signs and never broadcasts. It cannot move coins.
• It does not talk to the node at all. Its only input is the index file, opened read-only, so it holds no RPC credentials.
• There is no JavaScript on any page.

What it cannot tell you

There is no mempool index, so unconfirmed transactions are invisible. That is why an address page shows the unconfirmed balance as not indexed rather than as 0.00000000: nobody has answered that question, and rendering an unanswered question as a definite zero is the mistake that, in a wallet's send path, authorises spending the same coins twice.

Reorgs

PCoin reorganises often — around a 3% stale rate over its first ~2100 blocks — so the index unwinds losing branches by subtracting back the exact per-address amounts it had added, rather than recomputing them. Orphaned blocks are kept and still resolve to a page. See the reorg log.

Block pace and difficulty

LWMA retargeting is active, so the difficulty adjusts every block.

Coinbase maturity

Mined coins need 100 confirmations before they can be spent. Maturity is counted in blocks, which is the consensus rule; wherever a time estimate appears next to it, it is derived from the pace measured on this chain and never from the 600 s target alone, because the chain has not always run at target.
