Blockchain-powered Ad Exchange AdEx Launches Beta Release

Bitcoinist.net · February 27, 2018 · 10:00 pm

On February 26, 2018, right in line with the milestones laid out in their roadmap, AdEx launched the beta release of its blockchain-based advertising platform. Improvements in the release include an accessible UI for publishers to list their ad inventory on the platform and advertisers to bid for the listed ad slots and submit their ads.


The platform’s core is an Ethereum-based advertising marketplace that has already been tested out in the real sector. In late 2017, AdEx formed a partnership with global travel media provider Ink and conducted world’s first blockchain-driven ad auction, selling 1 million advertising spaces on airline boarding passes.

The project has chosen simplicity and accessibility over the extraneous bells and whistles offered by other projects attempting to break into blockchain-driven advertising. The AdEx team has developed its second generation of smart contracts, allowing bids to be stored as off-chain signed messages until accepted. This feature alone will allow for greater scalability potential, which is further reinforced by smart contract architecture that is compatible with second-layer scaling solutions like Plasma.

This new approach opens the platform up to broader integration opportunities. According to the official release announcement:

AdEx users (both publishers or advertisers) will have the option to log in with popular crypto wallets. Initially, only the Metamask option will be available, however Ledger and Trezor will be made available shortly.

Slow and steady wins the race

In an industry where many ICO projects rush “undercooked” products to market in an attempt to appease investors, the AdEx team took its time to do things right. The beta release was originally slated to be released ahead of schedule in October 2017, but the company opted to revert to the initial schedule, using the additional time to focus on building a better, more scalable product. The company explained its decision in a recent blog post:

At that point we made the decision to stick to our original release date for the benefit of a superior decentralized app. We knew that a part of our community would be disappointed but our choices have always been directed by scalability, efficiency and user experience.

Their decision allowed the team to “spice up” the beta release with features and improvements that weren’t scheduled to be rolled out until the release of AdEx V.2 in 2019. Therefore, the project is still well on its course, optimizing the whole year-long development stretch. It’s safe to say that shortly advertisers and publishers will be able to figure out for themselves if the tradeoff was worth it. In this regard, the team has expressed commitment to respond to users’ feedback and tweak the product accordingly.

Achievements and Partnerships

In June of 2017, AdEx launched its ICO and in less than 8 hours was completely sold out, raising 40,008 ETH and reaching their goal of being able to fully fund the development of the AdEx platform. ADX tokens were quick to be listed on exchanges as well and are currently trading on the following exchanges:

  • Binance
  • Bittrex
  • Changelly
  • EtherDelta
  • Gatecoin
  • HitBTC
  • Huobi
  • Liqui
  • Upbit

The project has also formed several significant partnerships within blockchain industry and beyond, including NEO, Wings platform, Fintech Blockchain Group, Snip, AdHive, the aforementioned Ink, and others. As for the future plans, the project aims to further explore scaling options, add more ad types, such as video and interactive ads, and work on its SDK for mobile platforms.

Introducing a Programming Language so Simple, It “Fits on a T-shirt”

http://plas2017.cse.buffalo.edu/

Blockstream is introducing Simplicity, a new programming language for blockchain-based smart contracts, intended for inclusion in Blockstream’s sidechains and eventually in bitcoin. The new language was presented by its creator, Russell O’Connor, Infrastructure Tech Developer at Blockstream, at the ACM SIGSAC Workshop on Programming Languages and Analysis for Security (PLAS 2017).

“Simplicity is a blockchain programming language that is so simple, it fits on a t-shirt,” O’Connor told bitcoin Magazine. “It is critical that smart contracts behave in ways that all participants expect, and applying formal verification to Simplicity allows us to achieve that.”

Simplicity is still a Blockstream Research & Development project, but there’s potential for its use in Blockstream products in the future, according to the company’s announcement.

“Simplicity is flexible enough that I anticipate many new, domain-specific, languages will generate Simplicity, and this will give users the freedom to generate smart contracts using the tools that most suit their needs,” added O’Connor.

O’Connor’s paper, titled “Simplicity: A New Language for Blockchains,” presents Simplicity as “a new programming language, designed to be used for cryptocurrencies and blockchain applications, which aims to improve upon existing cryptocurrency languages, such as bitcoin Script and Ethereum’s EVM [virtual machine], while avoiding some of the problems they face.”

bitcoin script is limited by design and unsuitable for complex smart contracts that need more than a small set of simple templates to perform tasks like digital signature verification. Ethereum, on the other hand, includes a more expressive and flexible, Turing-complete programming language, which allows for arbitrarily complex smart-contracts in principle.

But, in practice, Ethereum doesn’t support static analysis to pre-determine the computing resources that a program will require and, thus, filter out too costly contracts and infinite loops. Therefore, pre-paid “gas” fees are lost when an Ethereum program “runs out of gas.” The simpler bitcoin scripting, which supports static analysis, doesn’t present similar issues.

In a post to the bitcoin-dev mailing list, O’Connor proposed Simplicity as an alternative to bitcoin Script, noting that static analysis is important for both node operators and for Simplicity program designers.

“Static analysis is a technique that provides a universal algorithm to determine how much any Simplicity program will cost to run before you stake your money on it,” O’Connor told bitcoin Magazine.

Simplicity can be seen as a more flexible alternative to bitcoin scripting, not Turing-complete but expressive enough to build useful smart contracts for blockchain applications, or as an alternative to Ethereum, which will support static analysis and other desirable features including improved safety, formal semantics, and Merkelized Abstract Syntax Trees (MASTs).

While Simplicity is intended as a low-level language for smart contracts, O’Connor envisages the possibility of compiling programs written in higher-level languages (like Ethereum’s Solidity) to Simplicity.

“Ivy and the Σ-State Authentication Language are existing programming language development efforts that may be suitable for being compiled to Simplicity,” notes O’Connor in the paper. “For the time being, generating Simplicity with our [Haskell] and [Coq] libraries is possible.”

The next step in Simplicity’s development will be a bare-bones SDK (Software Developer Kit) that will include formal semantics and correctness proofs in Coq, a Haskell implementation for constructing Simplicity programs and a C interpreter for Simplicity. Then, the new language will be ready for initial deployment in the Elements project, Blockstream’s open-source codebase for sidechains, so that developers can start experimenting with the code.

But, as O’Connor stated on bitcoin-dev, “Only after extensive vetting would it be suitable to consider Simplicity for inclusion in bitcoin.”
