#243 Izaak Meckler & Evan Shapiro: Coda – A Succinct Blockchain

Source From https://letstalkbitcoin.com/blog/post/epicenter-243-izaak-meckler-evan-shapiro-coda-a-succinct-blockchain

One of the key scalability challenges with public cryptocurrency blockchains is that their size grows linearly with the number of transactions. Mature blockchains such as Bitcoin and Ethereum contain >170GB and >1 TB of historical data respectively. New nodes joining these chains need to download this data and verify it in order to become a “”full node””. The number of full nodes is a key measure of decentralization, and difficulty becoming a full node translates into future centralization.

In this episode, we are joined by the duo of Evan Shapiro and Izaak Meckler, CEO and CTO at O(1) Labs respectively. O(1) Labs is a pioneering company that uses zkSNARK technology in order to construct a cryptocurrency blockchain, called Coda, that solves the blockchain size scalability bottleneck. New nodes joining the Coda network will be able to trustlessly boot up in under a minute by verifying cryptographic proofs that attest to the validity of the current chain. This technology has great potential to enable decentralization, and for one blockchain to be a light client of another blockchain.

Topics discussed in this episode:

  • Scalability challenges of current cryptocurrencies
  • Background on O(1) Labs and their mission statement
  • How Coda uses succinct computational integrity technology (zkSNARKs) to enable further decentralization of blockchains
  • Snarky – a domain specific language for zkSNARK computations
  • Current state of Coda and roadmap

Tezos Foundation to Launch Grantmaking Process

Source From https://cointelegraph.com/news/tezos-foundation-to-launch-grantmaking-process

The Tezos Foundation is launching their first grantmaking process in August of this year, with plans to attract participants from various fields to apply for grants.

The Tezos Foundation has announced that it will hold their first formal call for proposals through an open grantmaking process, according to an announcement published July 13.

According to the announcement, Tezos’ public call for grants will be made in August of this year, and has determined three main areas as an initial target. These include “research that furthers the Tezos protocol and related technologies,” “development of tools and applications to support the Tezos ecosystem,” and “efforts to strengthen and nurture the burgeoning Tezos community.”

Within the initiative, the Foundation is reportedly going to invite community members, institutions, developers, and other parties which would be interested in applying for grants. All proposed projects should relate to one of the three grantmaking categories and will be reviewed on a monthly basis and evaluated by the Tezos Foundation Board.

On June 30, Tezos launched its beta network, calling the move an “inflection point” for the project. From that point on, users can begin validating blocks or “baking” after the first seven cycles which they estimate to be in about three weeks from the launch. According to Tezos’ website, the betanet is being launched in anticipation of a broader main network launch in the future.

Last month, the Foundation also announced the implementation of Know Your Customer/Anti-Money Laundering (KYC/AML) checks for contributors, in particular for those who ask for participation in initial coin offerings. The move was met with a negative reaction from the community.

Blockchain Auditing and the Industry’s "Knowledge Gap"

Blockchain Auditing and the Industry’s Knowledge Gap

The advent of smart contracts has long drawn interest for its potential to revolutionize business agreements. There’s just one problem, and it’s one that has affected many spheres of the cryptocurrency space: a knowledge gap. This gap exists between people who specialize in conventional legal terms and contracts and those who specialize in the technological programming of the blockchain.

On a recent episode of The Tatiana Show, host Tatiana Moroz interviewed Hartej Sawhney, president and co-founder of the cybersecurity firm, Hosho. Calling in from the back of a taxi cab in Istanbul, Sawhney explained that Hosho’s business advantage has developed around overcoming the knowledge gap.

“We see ourselves as a cybersecurity company that happens to focus on the cryptocurrency/ blockchain space,” said Sawhney. “What we’ve been doing to date has been building up a team of white hat hackers, people who have a strong background in the DevCon community.” For those unfamiliar with DevCon, it is considered to be one of the world’s largest and most well known hacker convention.

Headquartered in Las Vegas, Hosho focuses on auditing smart contracts “on any blockchain” and simulating cyber attacks to test the security of different systems. In addition, Hosho is also developing other cyber securities solutions for the space such as a multi-sig wallet for Ethereum and a Telegram group bot that detects phishing scams.

Fraud and Mistakes

Smart contract auditing remains the core of Hosho’s work. “Everything to date has been mostly people taking advantage of the fundraising mechanism of an ICO on the Ethereum blockchain,” said Sawhney. Auditing means that the developers are checking to make sure a smart contract is doing what it is supposed to do.

Sawhney pointed out that auditing smart contracts has shown him that there is a knowledge gap when it comes to finding developers with competence in Solidity, the language used to write Ethereum-based smart contracts, who are then able to perform these audits. And, according to Sawhney, the other side of this problem is that those developers who are actually proficient at Solidity, for the most part, are “too rich to get out of bed.”

Hosho’s strategy for dealing with the knowledge gap is finding people with cybersecurity backgrounds and teaching them Solidity.

Essentially, to the public, projects with misfiring smart contracts fall under the category of scams.

At EthBerlin, a gathering of 7–8 of the biggest cybersecurity professionals in this space will converge to standardize what a smart contract audit entails. Given the early state of the industry, Sawhney went on to say that the gathering, while sorely needed, is also well-timed for establishing an international framework for self-governance before one is imposed by an entity outside of the industry.

While Sawhney stated that the knowledge gap is a real problem for the industry, he noted that standards were improving. “In North America, every single exchange has made it a standard to check for a professional third party audit. Asia has some catching up to do … The speed at which a cryptocurrency gets listed in Asia is a lot faster than anywhere else. This is also what makes Asia an exciting market.”

The New Standard

Hosho’s standard for a smart contract auditing consists of a full audit of the language and code in their smart contracts followed by an itemized list provided to the client of all the quandaries that Hosho has identified with its capacity to be smoothly executed.

After the client addresses the errors, Hosho provides a second audit to make sure that the contract’s code has been fixed. Once approved, Hosho, in effect, stamps the code to certify that the code has been audited by a third party: That seal is valid up until the point that the code is edited again.

Although this seal is of interest to legal teams and government officials, Sawhney pointed out that, in the majority of cases, “the one person who reads our report is the exchanges.” This emphasis on exchange approval is tantamount to making smart contract audits a standard security procedure.

Other Topics

Like Sawhney, Tatiana’s other two guests were concerned with establishing and maintaining standards within the cryptocurrency and blockchain ecosystems. In addition to Sawhney and his views on cybersecurity, Connie Gallippi described the journey of forming her Bitcoin nonprofit, BitGive, while Bitcoin Magazine’s managing editor, Christie Harkin, explained some of the rules for maintaining editorial objectivity in cryptocurrency journalism as well as some guidelines for successful news story pitches.

We kick off todays show having a little fun talking about stupid shit the government does. Then a little bit of Bitcoin 101 before Cody Wilson joins in to talk about the role Bitcoin played in getting his project off of the ground as well as his very recent victory over the State Dept. in regards to his project from 6 yrs ago DefCad.org that released the first 3D printed gun files, on to the internet. Cody says this victory in essence has put an end to gun control forever. Not only will he bring DefCad back, he’s planning on expanding that file library exponentially.
