• The current block height and the time of the latest accepted block.
• The observed block interval over more than one short window.
• Network difficulty, and how any “hashrate” figure is derived from it.
• The current block reward (it follows from the height: see the emission explorer).
• Transaction count, fee levels and mempool size.
• Pool concentration, and how much work comes from unidentified miners.

Pearl drops Bitcoin’s older address formats. Its wallet creates Taproot addresses only, written in Bech32m and starting with prl1. Consensus also accepts P2MR (pay-to-Merkle-root) outputs, which the reference wallet doesn’t create. A valid-looking string still isn’t enough: wallets and services must agree they’re on the Pearl network.

Pearl’s script includes an XMSS post-quantum signature check, and the wallet can commit XMSS keys into a Taproot address. The original whitepaper described that check as disabled; the released code implements it. Either way, ordinary wallet spends use regular Taproot keys, so “post-quantum ready” should not be shortened to “post-quantum secure”.

Transactions compete for block space in a first-price fee market: miners fill blocks with the highest fee rates first. Your wallet estimates a fee, but confirmation time depends on demand, block production and which transactions miners pick.

One block is not finality. The right number of confirmations depends on the amount, the network’s conditions, the risk of a reorganization and the receiving service’s policy.
