PoEx announces a reduction in Proof of Existence Docproof Certifications
Fees from 0.5 to 0.25 mBTC
While changes in the USD-BTC exchange rate tend to capture all the headlines,
the more important figure for purely Bitcoin-based services is the accepted fee
rate per byte of data. As miners give priority to transactions with higher fees,
the average fee rate can rise and fall based on demand.
When we embed your docproof in the Bitcoin blockchain, we rely on a median fee
estimate that aims to give your transaction priority without being excessively
high. Up until now we have relied on adjusting the Docproof Certification Fee
manually to stay in line with average Bitcoin fees.
For the latest release of our open-source Proof of Existence software, we’ve
switched to a dynamic fee calculation. The software determines the certification
fee automatically based on the current estimated transaction fee rate, rounded
up to the nearest 0.25 mBTC (0.00025 BTC). Please consult the Proof of
Existence home page for the latest fees.
If you’re currently running an instance of our software, then after upgrading:
simply remove the
documentPrice setting from your configuration file to take
advantage of the new dynamic fees feature.

In December 2017, the PoEx team took up the development mantle to improve the codebase. The goal was to work toward a larger and more stable open source release.
Today, we are announcing the release of proofofexistence.com, as the first open-source public service to certify documents in the BTC blockchain.
The proofofexistence organization will continue to improve the software and surrounding services. We focus on the ease-of-use and quality of the core functionalities to make data and metadata from the Bitcoin blockchain more availabile.
You can start testing it today at proofofexistence.com.
Any feedback or questions can be sent at email@example.com!
Stay tuned for more!

We have long made use of free and open source software, programming languages,
and blockchain libraries and tools. Now it’s our chance to give back.
We’ve staked our claim on npmjs.com with the @poexio organization scope,
We’ve just released @poexio/blockcypher, a flexible Node.js client for the
ES6 promises, and with a configurable URL endpoint. The code is available under
a generous MIT License.
Watch for us on npmjs.com and at our home on GitHub.

As Bitcoin transaction fees have increased sharply in the past year, we have
been careful to set a sufficient docproof price so that a proof of existence can
be confirmed in the blockchain as quickly as possible, ideally in the next
We display the fee denominated in mBTC on the docproof web page (including in a
QR code), and in satoshis for our API users when they register a
hash. However, the exact price was missing when checking the status of a
docproof via our API. This has been remedied in our most recent update.
While we are committed to keeping version 1 of our API stable, we haven’t
stopped working on new features to bring you in 2018.
Happy New Year from the PoEx Team!
