How it's built

You do not need this page to use Numera. It is here because the guarantees mean more when you can see how they are held in place.

​

The shape of it

Everything that protects you sits in the two boxes on the outside. The service in the middle makes it fast and pleasant to use, and holds none of the guarantees on its own.

​

Four parts

Your device. Holds your passkey or connects your wallet, creates your trading accounts, and approves every trade. It is where the connection between you and your positions lives, and the only place it exists. The private pool. Where funds sit between deposits and trades. Money enters, and reaches your trading accounts privately. The blockchain contracts. The market itself. Holding funds, calculating prices, recording positions, paying out. Permanent and unchangeable, including by Numera. Numera’s service. Reads the blockchain, serves the site, streams live prices, and covers network fees for you.

​

What holds each guarantee

The pattern is consistent. Every promise is enforced by the blockchain or by your own device. Numera’s service makes the product fast and pleasant to use, and the guarantees stand on their own underneath it.

​

Built so the guarantees hold themselves

Funds live on the blockchain. Trades are approved on your device, and the system that submits them is restricted at the blockchain level to exactly five trader actions: buy, bet against, sell, close and claim. Market creation, settlement and administration sit outside it entirely. Privacy is structural. There is no record joining people to positions. Not encrypted, not permissioned, simply never created, which is a stronger position than protecting one. Market terms are permanent. Question, deadline, outcomes and fee ceiling are written to the blockchain at creation with no mechanism to revise them. Exits always work. Claiming is a direct action against the contracts. Even an emergency pause affects only new trades, leaving exits and claims fully available. Continuous markets run themselves. Each round opens and settles automatically, against a price fixed the instant it opens and a rule written before the round starts. No one chooses the winner. See continuous markets.

​

Network fees, handled

Numera’s service takes trades you have approved and submits them, covering the blockchain cost. It is deliberately narrow. One contract, five actions, and no ability to create a trade you did not approve. That keeps it a convenience layer with no access to your funds. The security of your position rests on the blockchain, not on this service. The reason it works this way is privacy as much as convenience.

​

Open by default

Every market, price, trade and payout is recorded publicly. Every number on the site can be checked against the blockchain directly. Here is what that lets you confirm for yourself. Your trade is recorded. Every trade appears permanently, with its size and price. Prices are genuine. They are calculated on the blockchain itself, so the number on the site is the number in the market. Markets are funded. You can read exactly how much each market holds against every possible payout, and see that it covers all of them. Terms are unchanged. A market’s question, deadline, outcomes and settlement rule were written at creation and carry no edit function. All of them are covered by a fingerprint stored with the market, so you can re-derive it from what the site serves and confirm nothing has moved. Privacy holds up. You will see accounts trading, and no way to tell who any of them are. That is the privacy design working, visible from the outside.

​

The design, in what is absent

There is no user list, no record linking any person to any account, and no administrative control able to move a position, hold a payout or revise a settled market. Those are not commitments that could be revised later. They are absences in the code, and you can verify them the same way you verify everything else here.
