XCH price (USDT)
Definition & technical note
The XCH/USDT spot price over time: the closing price of each candle.
Gate.io's public spot candlesticks for XCH_USDT, one request per range (5-minute candles for 6h up to weekly candles for All). USDT tracks the US dollar closely but is not the same thing.
Mempool
Cost used
Definition & technical note
Total CLVM cost of every pending spend bundle.
Sampled in this browser every time the mempool summary refreshes; kept for 2 hours.
Waiting bundles
Definition & technical note
Spend bundles sitting in the mempool.
Same 2-hour browser sample as Cost used.
Total fees
Definition & technical note
Fees offered by every pending spend bundle, summed.
Same 2-hour browser sample as Cost used.
Median fee rate
Definition & technical note
The fee rate in the middle of the pending cost: half the cost waiting in the mempool pays more, half pays less.
Sampled in this browser with the other mempool series: bundles are ordered by fee rate (mojos per cost) and the rate at half the total pending cost is kept. Weighted by cost, so a few large free spends pull it towards 0.
Blocks
Fees per transaction block
Definition & technical note
Average total fees paid in a transaction block.
Averaged per sampling window from get_block_records (block_record.fees); bounded number of windows regardless of range.
Cost per transaction block
Definition & technical note
CLVM cost used by a transaction block, out of the 11 billion a block allows.
For the newest transaction block of each sampling window: transactions_info.cost from get_block. One block per window (6 to 24 per range), each fetched once per session.
Transaction blocks per hour
Definition & technical note
How many blocks in the window carried transactions.
Counted per sampling window from get_block_records.
Spends per transaction block
Definition & technical note
Coins spent in a transaction block.
For the same sampled blocks as Cost per transaction block: the number of removals from get_additions_and_removals. Reward claims are created, not spent, so they are not counted.
Share of transaction blocks
Definition & technical note
Transaction blocks as a share of all blocks (roughly a third).
Counted per sampling window from get_block_records.
Time between transaction blocks
Definition & technical note
Average gap between consecutive transaction blocks.
Averaged per sampling window from get_block_records timestamps.
Network
Netspace
Definition & technical note
Estimated total space farming the network.
get_network_space between each sampling window's first and last block — the node's own difficulty-based estimate, not derived by us.
Difficulty
Definition & technical note
The proof-of-space difficulty blocks were farmed at.
From the block records the other series already fetch: a block's weight is the chain's cumulative difficulty, so the weight step from one height to the next is that block's difficulty. Median per sampling window. It changes once per epoch (4,608 blocks).
Blocks per hour
Definition & technical note
All blocks (transaction and non-transaction) per hour.
Counted per sampling window from get_block_records.
