Anatomy of
the last block.

Every field below is the real latest Cyprus-1 block, redrawn the moment a new one lands, and each one tells you where to check it yourself.

Reading the latest block…

Quai is a tree: Prime ⊃ Region ⊃ Zone. A block's order says how high up the tree its proof reached. Live today: one region and one zone (Cyprus-1), expansion number …. The dashed tiers are designed capacity, not live.

The anatomy

…

hash

…

This block's fingerprint. Change one bit inside it and this changes completely.

verify

parent hash

…

The hash of the block this one builds on. That link is what makes it a chain.

timestamp

…

The time the miner stamped into the header.

verify

transactions

…

Transactions carried in this block. A block with none still carries proof of work.

entropy

…

parent (zone) …

PoEM weighs the entropy a hash removes, so every node picks the same winner. This is the chain's running total, in raw hex, as the header reports it.

reward ledger

…

Which coin the miner of this block chose to be paid in, QUAI or Qi.

exchange rate

…

The protocol's live input for QUAI ↔ Qi conversions, in raw protocol units, read fresh from every header. It is not a peg.

gas used / limit

…

How much of this block's execution budget its transactions used.

verify

efficiency score

…

The raw security-efficiency score in the header. It is the number the expansion trigger watches.

the trigger in go-quai

expansion number

…

0 = the original single zone. Quai's design adds zones; today there is one.

difficulty

…

The work target this block's miner had to meet. The protocol retargets it to keep block time steady.

Don't trust. Check.

Every live number on this site comes from a public source you can query yourself. Each command below hits the public Quai RPC or SOAP API directly. Paste it into a terminal and compare.

QUAI burned

The balance of the SOAP burn sink. QUAI sent there is gone; its balance is the cumulative executed burn. The result is wei (hex): divide by 10^18.

curl -s -X POST https://rpc.quai.network/cyprus1 \

the sink on Quaiscan supply.qu.ai

Cyprus-1 block height

The live height of Quai's zone chain. A new block lands about every 5 seconds.

curl -s -X POST https://rpc.quai.network/cyprus1 \
  -H 'content-type: application/json' \
  --data '{"jsonrpc":"2.0","id":1,"method":"quai_blockNumber","params":[]}'

Quaiscan blocks

The latest block (order, workshares, uncles, entropy)

Every field on the anatomy page comes from this one call. order is 0 for a prime block, 1 for region, 2 for zone.

curl -s -X POST https://rpc.quai.network/cyprus1 \
  -H 'content-type: application/json' \
  --data '{"jsonrpc":"2.0","id":1,"method":"quai_getBlockByNumber","params":["latest",false]}'

Quaiscan

SOAP revenue

Revenue earned by merge-mined parent blocks (BCH, LTC, DOGE, RVN), queued to buy and burn QUAI. Earned, not the executed burn: that is the sink balance above.

curl -s https://soap.qu.ai/api/revenues

soap.qu.ai

Hashrate by algorithm

The protocol's own estimate per algorithm: SHA-256 and Scrypt arrive through SOAP merge-mining; KawPoW is Quai's native algorithm.

Zones live today

expansionNumber in every header counts tree expansions; 0 means the original single zone. The auto-expansion trigger lives in go-quai's protocol params.

curl -s -X POST https://rpc.quai.network/cyprus1 \
  -H 'content-type: application/json' \
