PoEx sponsored the Distributed Systems exhibition at the Gray Area Festival in
San Francisco. The “#distributedsystems” show is the largest curated exhibition of Blockchain, distributed and decentralized artworks. 19 artworks by 30 international artists were shown at the opening of the Festival on July 26th with the exhibition open to the public until August 3. Thousands of people saw the works from the festival to show closing.
Highlights from the exhibition included one of the earliest Bitcoin and Blockchain-based artworks by artist Simon Denny’s. His piece, Modded Server Rack Display: Hacking Trust (2015) includes instructions a Bitcoin miner and stood as a column next to another column-like work. New Palmyra’s Tetrapylon stood out as one of largest 3d printed artworks ever constructed and had the distinction of being placed onto the Ethereum blockchain and at the event on Bitcoin blockchain on Proof of Existence.
Chief Architect of PoEx’s Proof of Existence, Christopher Adams, spoke at the festival about what it means to release something onto the Blockchain, technically. He also discussed the New Palmyra Tetrapylon, how it was created in collaboration with Creative Commons, RE:3D and a community of artists from New Palmyra.
Artist Rob Myers 2018 work, SchellingFlags. As Myers describes the piece, it is a “blockchain-based system for establishing the aesthetics and allegiances of flags in a decentralized way.” Myers continues, “Using the blockchain, SchellingFlags supports the construction and use of flags as ideological focal points for decentralized social co-ordination. Any individual can create and share a flag, and any individual can support it. The most popular flags are displayed by the SchellingFlags graphical interface to provide a map of its ideological landscape.”

In addition to the artworks shown at the festival, theorist and PoEx developer Clement Renaud discussed his research on manufacturing in the “Greater Bay Area”, meaning Shenzhen, standing in stark contrast to the traditional San Francisco Bay Area where the festival took place.
Renaud pointed out the foundations for the hardware powering the Blockchain and cryptocurrency scene, how and where they were made. Also of note, is some documentation on this scene, and not to be missed, Proof of Hardware with knowledge building from Mr. Renaud and others affiliated with PoEx.
PoEx is proud to have sponsored the Gray Area Festival and Distributed Systems exhibition and looks forward to future creative technology projects expanding upon the innovation of the blockchain. If you are building some technology using one of our projects such as Proof of Existence of Proof of Hardware, let us know @poexio.

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.
Proof of Existence is Open Source
Did you know Proof of Existence is Open Source software? The code to run your own instance, compare to our public service, add your own ideas or request features is all available on the Proof of Existence website. If you have ideas for features, please let us know here: Proof of Existence.

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 firstname.lastname@example.org!
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.
