Every Prismatic block holds the one before it.
Blocks struck at 12 zeros are joined into one chain. Each one's header carries the hash of the 12-zero block struck before it, the way Bitcoin's blocks point back. It is Strike a Block's own chain, not Bitcoin's. Every link is below, and your browser re-checks them all.

Link 1 at the top, the newest at the bottom.
Read down. Every plate shows two hashes: the previous link's, written inside the block, and its own. A link's own hash is the “previous” of the link below it: the same 64 digits, twice.

Nothing is shown here rather than something out of date. Your connection or our server may be having a moment.
No link has been struck yet.
The first Prismatic block struck from here on becomes link 1. It has no link before it, so the place in its header for a previous hash holds 32 zero bytes. The block struck after it will carry its hash, and the chain goes on from there.
See the Prismatic tierthe startLink 1 is the oldest. Nothing comes before it.
Dates are Pacific time.
A link's date is the day that header was mined; where a link strikes an
older block again, the first strike's date is given separately. The same
data, for your own tools: /api/v1/chain.
What the chain is, and what it is not.
- How much work is one link?
- Each link's hash starts with 12 zeros. Finding a hash like that took the chip about 281 trillion tries on average. Checking it takes one, which is what your browser does on this page.
- What ties one link to the next?
- A link's hash is worked out from its whole header, and that header contains the hash of the link before it. So each hash covers the one before. Changing an old link would mean mining it again, and every link after it.
- How far can it be trusted?
- As far as one chip's work goes. The whole chain is made by a single small mining chip, so it is a record of order and effort: which link came after which, and the work each one took. It is not a defence against someone with far more mining power.
- Is this Bitcoin's blockchain?
- No. It is Strike a Block's own chain, in Bitcoin's block format. It is not Bitcoin's blockchain, there is no coin or token, and nothing here has monetary value.
- Is every block a link?
- No. Only blocks struck at 12 zeros, the Prismatic tier, are links. Blocks at 8, 10 and 11 zeros are standalone and are not part of the chain.
- Why do some links say they were struck again?
- A 12-zero block struck before the chain began can be struck again as a link. A link like that says so on its plate, with both dates, and points to the first strike, which is kept as it was.
The next link is open.
A Prismatic strike is one line of yours, mined to 12 zeros for $99. The block it makes becomes the newest link and carries the hash of the link before it.
