Tags: Conversations, Art, Questions, Life, Thinking

Hi everyone! Welcome back! Send some ideas my way and we can get these personalized with a name! Anyways, let’s start today’s talk.

I want to pose a question to you: What do you see in my art? Is there some kind of charm to them? Is there some feeling that’s elicited when you see it? Or are they flat and have no character? Do they look pretty? Do they look different? Let me know! I want this feedback; it’s quite important to me to have you talk to me as much as I talk to you.

After answering that I have another: What do you see in others’ art? With the same question bombardment as above hahaha. As subjective as this topic is, there are some objective truths to them underneath it all, and that is something that I’m always curious to learn about.

Sorry for the thought bombing but these questions, as often as they come up, really are what help people like myself out. Heck, it even helps you understand yourself better! A deep reflection is a two way street ;)

Since this is a question based one full of conversations, instead of me continuing on I’ll end it here. I know, it’s shorter than normal, but is it really?

Thank you for reading, as always. Have a good day, evening, afternoon, night!

I’ll see you when I see you.

With The Right Question, We Can Find The Answer to How We Want To Live Our Lives.

Photo by Cherry Laithang on Unsplash

“Have you decided how you want to live?” It’s not what you will do for a living, but your holistic approach to life in general.

Late at night, I think it was around 2 A.M. I was laying down about to end my day, while I unanticipatedly had a crystal clear answer of how I want to live my life from now on.

Because of the plenty of time I have at the moment during the pandemic, the only activity I diligently do is Yoga to keep my body and mind healthy. At the Yoga class, I’ve met people who have become a parent and surely have more life experiences than me. The life stories they shared got me thinking “Is that how they want to live their lives?” Is that the path they had chosen? As a housewife, as a Yoga teacher, as a single mother, as a bachelor.

Grow up, be a man, you say.

Do your knees not buckle?

Forge your path, chase your dreams, you say.

Do your eyes not wander?

Be open-minded, believe in truth, you say.

Do your ears not ring?

Walk tall, keep moving, you say.

Do your feet not ache?

Lead well, uplift others, you say.

Do your legs not tremble?

Sing loudly, dance freely, you say.

Do your chains not yet remain?

Open your heart, love without end, you say.

Do your scars not scream at you?

Rest your head, sleep now child, He says.

But All You Ever Talk About is Your Books

First and foremost, I’m quite proud of my books. And based on all the great feedback I’ve gotten I know they can make a big difference for music makers out there.

I’m not going to shut up about my books, and it’s not really a thing of how many sales I can get. It’s about how much of a dent in the universe I can make. It’s about how much of an impact I can make.

Maybe this wasn’t totally obvious either, so let me put it as clearly as I can: I’m also a musician coach, and have been for many, many years now! That’s why I created Music Entrepreneur HQ and all associated products. Not so that I could self-promote better, strange as that may sound.

But the reality is I talk about a lot more than just my books.

I talk about my courses.

I share about spirituality.

I answer questions.

And on my podcast, I’ve repeatedly shared about my comedic tribute to the 80s project. I even played guitar on the latest episode of the show.

I realize I haven’t released anything since Spirit Searcher, Vol. 1. But I’m creating the possibility that 2021 will be a better year.

I could release a few remastered tracks, but I just haven’t gotten around to it yet.

To top it all off, I’ve also got a substantial backlog of live performance videos to share. I haven’t nailed down a release schedule yet, but I thought you might like to know.

Why Is AMPLIFY Based On Ethereum Smart Contracts?
Tags: Defi, Ethereum, Smart Contracts, Ampt Defi

In today’s post we will explain our reasoning behind our choice of the Ethereum platform for the project’s needs!

The first point is the prevalence of ETH. We realize that ETH has very high adoption and popularity all over the world (after all, it is the second most popular cryptocurrency after Bitcoin). Using ETH will be more financially viable for our users since creating an ETH transaction gas cost is minimal, while the imminent launch of Ethereum 2.0 will make transactions even faster and cheaper.

Besides, it is Ethereum that is the most popular blockchain among developers: every day, dozens of new solutions and tools pop up on the network, helping projects become more technologically equipped.

Thanks to the popularity of this blockchain, we will have an easier time finding both engineers as well as various development frameworks on Ethereum.

Atomic swap exchange is now available for iOS and Android within the Atomex wallet
By: Baking Bad
Tags: Ethereum, Smart Contracts, Atomic Swap, Blockchain, Tezos

Atomex has launched atomic swap exchange on mobile platforms iOS and Android through its own cryptocurrency wallet, which can now be downloaded for free through the AppStore and Google Play. Decentralized cross-chain exchange is available through your own non-custodial mobile wallet, which also allows you to receive, send and store cryptocurrencies, as well as easily participate in Tezos (XTZ) staking via delegation mechanism.

Atomic swap

Atomic swap is a protocol for trustless cross-chain exchange of assets using Hash Time Locked contracts (HTLC). Atomex combines an improved version of the Atomic Swap protocol with a centralized order matching engine to ensure the liquidity and safe execution. Atomex crypto wallet supports Bitcoin, Ethereum, Litecoin, and Tezos, as well as stablecoins such as (ERC20 token), (FA1.2 token), and wrapped Bitcoin.

Atomex supports Bitcoin, Litecoin, Tezos, Ethereum and stablecoins

Push notifications on swap execution

The implementation of atomic swaps on mobile devices includes one important feature. The application is required to send payment and redeem transactions within a certain time period (see Atomic swap on practice for more details). On a mobile device, the application runs in the background for a short time, so Atomex devs applied Push notifications to be sent when the user has to open the application to complete the atomic swap. In all outstanding cases the redeem transaction can be sent by a third-party service, the same way as it works when the user receives the purchased currency on an empty Ethereum or Tezos wallet, for example, swapping BTC -> ETH or BTC -> XTZ.

A pleasant feature for Tezos wallet users

The Atomex application is a product of the Baking Bad team, well known in the Tezos community for the Baking Bad delegation dashboard and TzKT explorer. Using the TzKT data Atomex displays publicly known entities in the list of operations. This is very convenient and among other things allows you to distinguish your own transactions from the staking reward payments. In addition to that, Atomex tracks bakers’ statuses on the Baking Bad listing and will warn you if you try to delegate your tez to overdelegated or “bad” bakers.

What’s next

The following features will be added in the near future:

Detailization of the atomic swap process.

Improved management of your HD addresses (selecting a specific address when sending assets).

Allowing users to add arbitrary Ethereum and Tezos tokens to the wallet.

Segwit addresses support for Bitcoin

Ledger hardware wallet support.

Various UX improvements and advanced account management.

New currencies and tokens enabled for atomic swap.

We are always glad to receive suggestions and feedback from our users. Feel free to evaluate and review the Atomex application, we will surely take that into account with the new updates!

- Yours, Baking Bad team!
Obelus Oracles, a step by step conversation.

Obelus Dev, [16.12.20 00:08]

What if there was a token that was generated by a pyramid scheme. But the losers get most of the token

Obelus Dev, [16.12.20 00:08]

Just throwing an idea out there

Ataxia, [16.12.20 00:08]

you mean hex

Obelus Dev, [16.12.20 00:10]

Why isn’t hex used for oracles then? If that’s the case the supply of the token should be forcibly distributed

Obelus Dev, [16.12.20 00:10]

Hex also has a centralized component

Ataxia, [16.12.20 00:10]

yeah I’m half joking

Ataxia, [16.12.20 00:10]

[In reply to Obelus Dev] “What if there was a token…”

but what do you mean with this

Ataxia, [16.12.20 00:11]

pyramid schemes usually just collapse all of the sudden

Obelus Dev, [16.12.20 00:12]

Tbh. I am shilling. I can share the source code if that’s okay

The inverse token would be good for oracles. A pyramid is like a blackhole. The inverse of a blackhole is a forcefield

I’m working on communicating this idea. Because most people say it’s too complicated.

I think it’s simple. Super simple.

We all know pyramids pull money to the center. So if a token was created in inverse of that flow, you’d get an inverse gradient (or ring )

Ataxia, [16.12.20 00:14]

right and how does this pyramid operate

Obelus Dev, [16.12.20 00:15]

Similar to p3d.

except, when you sell. you get ETH & the inverse token. The more of a loss you take, the more of a multiplier you get

Ataxia, [16.12.20 00:16]

and it knows your PnL/

Ataxia, [16.12.20 00:16]

?

Ataxia, [16.12.20 00:16]

interesting

Obelus Dev, [16.12.20 00:17]

[ Photo ]

PnL?

cost per bond? yes.

Ataxia, [16.12.20 00:17]

[In reply to Obelus Dev]

nice

Ataxia, [16.12.20 00:18]

i idg

Ataxia, [16.12.20 00:18]

and how do you give value to the loser‘s token

Ataxia, [16.12.20 00:18]

LP incentive?

Obelus Dev, [16.12.20 00:19]

they earn on oracle verifications. (they can also earn by staking in the core contract for the “friction fee”)

but the entire idea is that the tokens are inherently distributed by market forces, which makes them great for governance.

Obelus Dev, [16.12.20 00:19]

in order for a whale to control the total supply. they have to buy back an entire pyramid and buy it to the ground floor

Ataxia, [16.12.20 00:21]

what does earn oracle verification mean?

Obelus Dev, [16.12.20 00:22]

everything the oracle verifies, those who have staked in the oracle get paid.

Obelus Dev, [16.12.20 00:22]

the oracle is made up of a “roundtable of watchers”

they are voted in by this inverse token.

and they can watch anything they want.

Sports, elections, weather, etc.

Ataxia, [16.12.20 00:32]

nice concept

Ataxia, [16.12.20 00:32]

are you just going to launch it?

Obelus Dev, [16.12.20 00:35]

it has been launched.

I am just trying to figure out how to explain it to people better.

We’re at 52 eth in the reserve & 140eth in the contract.

The majority of that eth is people not taking their dividends

The oracle is ready to be deployed too.
How Blockchain wallet works?

Tags: Hyperledger, Smart Contracts, Blockchain, Cryptocurrency, Hyperledger Fabric

What is block chain wallet?

Block chain wallet is a program that allows monitoring and conducting crypto currency between two wallet addresses which can be accessed using private and public key. Both key will be in Hash format. A hash is a string of numbers and letters, produced by hash functions.

Transactions are being recorded on the block chain in crypto wallets. If someone wants to send you crypto currency, it means they are assigning blocks to your block chain wallet.

How blockchain wallets work?

Blockchain is an digital database which keeps an unchangeable record of data operations. Group of these operations called “blocks”. Here is general flow of how it works:

If someone want to send money using crypto wallet. Transaction is represented as block. The Blocks which is broadcast to every party in network. Those in the network approves the transaction is valid or not. If block is valid, it will be assigned to receiving crypto wallet Received block is permanent and unalterable. Commit the transaction

Type of Wallet

Here is overview of different type of crypto currency wallets:

Mobile wallet — A wallet which run from the smartphone application. Web based wallet — A Web based wallet is hosted on any VPS or real device. Sometime it is called as hot wallet or web wallet. Desktop wallet — A wallet which run from the desktop devices. Safer compared to mobile and web wallet. Hardware wallet — Required dedicated hardware to hold crypto currency. USD sticks can be used for this wallet. This kind of wallet require internet to perform transaction and it will be offline after transaction commit successful. Coin wallet — Wallet which only work for specific coin.

Time to shape your own financial universe
By: Chainge Finance
Tags: Defi, Decentralized Finance, Blockchain Technology, Smart Contracts

Bitcoin is laying the foundation of a whole new world right as we speak. A world with no intermediaries or centralized institutions where information and value will be free of all restraints and limitations. 10 years of BTC history slowly but surely turned it in digital “gold” — an unstoppable force heading straight up.

Nowadays, value is dictated either by demand or consensus. Demand gives value to things like food and housing while consensus offers it to non-essential resources such as gold, diamonds, oil or even fiat. The latter’s actual value stands in its recognition by the masses.

And the issuers of these resources dictate their increase in popularity using several means including governmental and military forces. This is also the case for Bitcoin. The more people and institutions recognize and concede on its value, the more it rises.

Other crypto currencies follow this same pattern. However, coins being a valid payment method for let’s say gas, could further create and increase their tangible value due to demand.

The problem arises when we consider where this demand comes from.

Mandatory need for payments? Making transactions?

How about concluding smart contracts?

Smart contracts have remained until recently, unexplored in terms of potential and intrinsic business value. Their sole usage was related to miscellaneous app development.

But DeFi brought smart contracts into the spotlight and uncovered their amazing business value.

Just think about the fact that all loan operations could be implemented and carried out through code. A simple, transparent and efficient way to manage the entire loan process would be available to anyone, while keeping an exceptionally low cost compared to current bank fees.

Taking a closer look at the ICO smart contract developed by Fusion (website here) reveals a coded automated finance service very similar to IPO. With over 13000 users and 72 mil USD worth of ETH over the hard cap automatically returned to participants; not one single server was run and human resources were a fraction of what traditional institutions employ. And still, we managed to carry out the IPO style ICO by simply deploying a smart contract. The total cost of the whole operation added up to a mere 5 ETH for gas.

This was made possible by decentralized, coded, and automated finance applied through smart contracts.

We are confident any type of financial service can be coded and automated. Thus, the entire financial system will run smoothly, with no boundaries or middlemen involved.

Fusion is especially designed to serve as the infrastructure behind it all. And Chainge will be the exclusive medium that empowers mass users so they can enjoy the whole range of benefits that come with digital, coded and automated finance.

With Chainge, anyone can be an independent digital/crypto bank-like entity, serving a worldwide network of users.
Smart Contract Capabilities Added To The Theta Core Network
By: The Crypto Basic
Tags: Smart Contracts, Blockchain, Cryptocurrency, Cryptocurrency News, Altcoins

The Developers of the streaming platform on the Theta blockchain have updated the project’s network and added the ability to deploy smart contracts, among other improvements.

Theta is one of the projects that is developing after the ICO. ICO sales of $20 million THETA token were completed in January 2018 to accredited investors.

According to Theta Labs, the project’s network now supports smart contract capabilities, starting with block 8,411,427. As part of the update, changes were also made to the staking process. The asset staking threshold has been lowered to 1,000 THETA, starting from block 8,411,427, for both new nodes and additional staking of existing nodes.

Other changes include an updated website with Protocol information, an updated block Explorer that provides smart contract data, and the Theta-js Javascript SDK developer kit.

This update will not require existing token holders to take any actions or move tokens. No token replacement is taking place.

Other significant improvements include the Google Chrome extension for Theta wallets. In May 2020, Theta announced the launch of an updated version of the Theta 2.0 network and collaborated with Google.
Features of Smart Contracts in DCI Ecosystem
By: Dci Ecosystem
Tags: Features, Smart Contract Blockchain, Smart Contracts, Dci Ecosystem

Hello, Today we will talk about the various features of smart contracts in DCI Ecosystem.

Smart contracts are digital #algorithms or computer programs that facilitate, verify, or enforce the negotiation or performance of an agreement. The smart-contract describes a set of terms, which are automatically fulfilled by the network. All in one transaction!

𝗦𝗺𝗮𝗿𝘁 𝗰𝗼𝗻𝘁𝗿𝗮𝗰𝘁𝘀 𝗵𝗮𝘃𝗲 many 𝗯𝗲𝗻𝗲𝗳𝗶𝘁𝘀, such as:

✔️ Immutability

✔️ Openness

✔️ Reduced complexity

✔️ Security

✔️ Autonomy

✔️ Lack of human element (errors)

✔️ Lack of intermediaries, which reduces the operational costs

DCI Ecosystem uses Smart Contracts to create automatically executable legal agreements between the parties.

The digital/smart contracts allow companies to enter into a contractual agreement without the need to rely on honesty from the respective counterparty involved in the transaction. The terms are embedded in the “digital contract” pre-ante the deal and the fulfilment of those contracts is made sure by the software code without the need to have any human interaction. This ensures that the #transactions are fast, low cost, and legally binding.

DCI ecosystem allows businesses & individuals to tokenize their securities using a smart contract that is defined and stipulated in compliance with the security regulations of the state or country where it is issued.

DCI Ecosystem in its target state will be fully decentralised and uses programmable smart contracts to allow DApps developed in EOS blockchain or integration with open APIs to external software providers.

99 Red Balloons (R99)
By: Obelus Voto
Tags: Fomo, Ethereum, Smart Contracts, Cryptocurrency, Bitcoin

First of all. Sorry. The board had to be re-initialized. Message PiZZatoshi for reimbursements.

When all the kingdoms have been claimed, the 99Red Balloon contract will launch and will need to be initialized as well. Jump starters get bonus Rubix Fractal tokens which, like all cards will be used in the next iteration of this yugioh-like card game.

The Red Balloon contract (R99) is part of a partnership with https://www.spam.link/. $SPAM is a deflationary token. The mechanics of $SPAM and the game theory of R99 compliment each other.

There are several other tokens integrated into the R99 contract.

Different tokens are consumed to creates cards. To obtain different cards kingdoms have to be in certain arrangements on the board.

Sometimes they have to be in the center. or in the corners or adjacent to other specific kingdoms. The above is just examples. Once they align their combination the card can be obtained by clicking on the relevant kingdom.

$SPAM is used to stock up balloons to compete for the next Balloon Giver. All spam stocked earns dividends, the account that stocked the most balloons becomes the Balloon giver. Once the current balloon pops, the panda starts with a new red balloon. This can happen 99 times. The balloon popper gets the R99 token.

To pop a balloon the kingdom holding the balloon needs to change into the floating kingdom position. The special position above the board.

All cards purchased benefit the kingdom holding the balloon. Rugs from the Feather kingdom can be purchased to blow the balloon around.

Chainlink’s Network Effect Creates More Secure and Lower Cost Oracles for Everyone
Tags: Smart Contracts, Blockchain Oracle, Blockchain, Chainlink, Network Effect

To better understand the major impact that network effects have on the technological adoption of a protocol, we define what a network effect is, look at its foundations in Bitcoin and Ethereum, explain the benefits of the Chainlink network effect, and showcase how it’s achieved in a completely decentralized and open-source manner.

The Network Effect Explained

A network effect, otherwise known as Metcalfe’s law, is a phenomenon whereby the value of a service or application is determined by its number of users. For every additional user, the network as a whole becomes more valuable/useful to all current users, as well as becoming more enticing for potential new users.

An obvious example of a network effect today is the rise of social media. The reason why Facebook, Twitter, and Youtube are so widely used is that they provide single aggregated platforms where creators can share their content to a large audience while consumers have access to a wide selection of content. Family and friends that collectively use the same platform make it inherently valuable to those users, providing them with the most value/utility per unit of effort. In contrast, having your family and friends spread out across 50 different Facebook-like equivalents requires an extensive amount of work to keep in sync with them all, ultimately leading to a smaller social network with less usefulness to everyone.

A visualization of a growing network effect (source)

Network Effects in Bitcoin and Ethereum

Network effects can also be seen in leading cryptocurrency networks. The reason why new crypto users usually gravitate towards Bitcoin is because it has the largest mindshare in the world. Not only is that due to being the first cryptocurrency in existence, but Bitcoin has also accumulated a massive network effect of over 100M+ wallets spread around the world, which collectively hold over $340B of circulating coins. Each additional user/holder increases the collective belief of Bitcoin being a secure and reliable store of value, further bolstering its value proposition for existing and future users, as well as enhancing its network security via more fees for miners.
Learn Solidity: The Factory Pattern
By: Wissal Haji
Tags: Ethereum, Smart Contracts, Solidity, Cryptocurrency, Programming

Clone Factory Pattern

The problem with the previous pattern is that it wastes lots of gas since all child contracts will have the same logic and we redeploy almost the same contract each time — same code but different context. We need a way to deploy only one child contract with all the functions and make all other child contracts act as proxies that delegate calls to the first child contract we created and let functions execute with the context of the proxy contracts.

Photo by the author.

Fortunately, there is the EIP-1167 specification that defines how to implement a proxy contract cheaply. This proxy will forward all calls and 100% of the gas to the implementation contract and then relay the return value back to the caller. The bytecode of the proxy contract according to the specification is

363d3d373d3d3d363d73bebebebebebebebebebebebebebebebebebebebe5af43d82803e903d91602b57fd5bf3 . The bytes at indices 10-29 (inclusive) are replaced with the 20-byte address of the master functionality contract (the contract to which we will delegate the calls).

The whole magic of the proxy contract is done using delegatecall . You can get an idea of how it works by reading this article.

Let’s see now how to make this work. First, you need to grab the implementation of this specification, which you can find on GitHub. Copy-paste the code of CloneFactory in your project.

The code we’re going to use this time is as follows:

This time, we used the createClone function from the GitHub repository to create child contracts instead of the new keyword.

You can deploy the contracts by creating a new migration file in Truffle that looks like this:

To test if the code works, I created a test file that you can try on your own to make sure that everything is working as expected:
Introducing Script-level Debugger
Tags: Bitcoin Sv, Scrypt, Smart Contracts, Bitcoin, Debugging

Previously, we introduced the source-level debugger in our IDE, which enables debugging at sCrypt code level. Today, we are thrilled to introduce its advanced version, which allows debugging at Script level. This would be immensely helpful for users who desire to cope directly with raw Script, e.g., for customized optimization.

Script Debugger

More specifically, the Script-level debugger enables you to:

Map between sCrypt and its Script output in realtime

Set breakpoint and step in Script

View the main and alternative stack

This is a premium feature and requires a license. To purchase a license, just send us a baemail at scrypt@moneybutton.com. For more information, please visit our IDE homepage.
Uniris Weekly Update N°50 — EN. News of the week of December 7, 2020.
Tags: Blockchain, Smart Contracts, Cryptocurrency, Technology

“Development is so simple and easy that no technical skills are required to fully deploy and use Uniris smarts-contracts! Everyone will be able to create and deploy smart-contracts, while promoting the security and reliability in the Uniris ecosystem”.

Akshay — Chief Product Officer (CPO) Uniris

Innovation at the heart of our smart-contracts

Programmable triggers: simplicity accessible to everyone

No notion of time is available in the current Blockchains. Uniris smarts-contracts allow time-controlled actions to be carried out as easily as automatic bank transfers.

Different types of triggers are possible: time, transactions…

For example, whether it is a vote or an ICO: opening and closing can now be automated. It is the network itself that takes care of the recurrence and no longer an external network. You will be able to define the specific conditions of your smart-contracts and the script will be automatically triggered according to the programming.

A new concept: the inheritance constraint

Until now, smart-contracts were triggered by users via transactions. The status of the contract changes with each direct interaction. Uniris innovates by using the UTXO model. Users will still perform transactions to contracts, but they will ask the nodes to perform this transaction in the chain. The node will then need the private key to generate the new transaction. The purpose of inheritance constraints is to avoid any malicious behavior of the nodes (code modification, sending money…).

You can now automate your digital world in a few minutes on the Uniris network and simplify your daily life.

CRUDE.BTSP (CBTSP) is the liquidity token for bitsharescrude and is part of the means by which bitsharescrude raises funds for its stable coin CRUDE.NGN. It can only be gotten by a liquidity pool contract, where a user adds BTS and CRUDE.NGN to the liquidity pool. The resulting contract token can immediately be sold for bitshares via CRUDE.NGN at almost three times its original value or held until the amount of bitshares in the pool has doubled. The user can also add bitshares to the pool via swap operations to get almost twice the amount he would have gotten from the market(This is only profitable above a price diffrence of -45% )…

CRUDE.BTSP is expected to gain more value, as more bitshares is added to the pool over time and as such encourages users to provide liquidity to the pool or to swap bitshares for CRUDE.NGN.

It is currently not possible to access the pool from the Bitshares UI or web wallet, users can only access this feature from the mobile wallet. However it is possible to buy the resulting supply from the web wallet to hold until the time when it has gained a reasonable valuation.
Solidity Fundamentals: Types

Fixed-sized byte arrays — bytes1 (byte), bytes2 … bytes32

The value types bytes1 , bytes2 , …, bytes32 includes a sequence of bytes from 1 to 32. The keyword byte is alias for byte1 . Beside, fixed-sized value type has got member function named length which yields the fixed length of the byte array (read only). And also bytes with a fixed-size variable can be passed between contracts.

The type byte[] is an array of bytes, but due to padding rules, it wastes 31 bytes of space for each element (except in storage). It is better to use the bytes type instead.

We use hex representation to initialize them in Solidity:

Play Conway’s Game of Life on Bitcoin Forever
Tags: Bitcoin Sv, Scrypt, Smart Contracts, Bitcoin, Conways Game Of Life

Conway’s Game of Life is a fascinating zero-player game on a grid, whose evolution is determined by its initial state. Each generation is a pure function of the preceding one.

We implement the game on Bitcoin SV. Each generation evolves to a new generation when triggered by a bitcoin transaction. The game lives completely on chain. As long as there are transactions interacting with it, it lives on chain forever.

Any live cell with fewer than two live neighbours dies, as if by needs caused by underpopulation. Any live cell with more than three live neighbours dies, as if by overcrowding. Any live cell with two or three live neighbours lives, unchanged, to the next generation. Any dead cell with exactly three live neighbours cells will come to life.

Implementation

The generation of the game is stored as the state of the contract. We show the part enforcing rules below. The complete contract can be found here.

Smart Contract Audit

To ensure the quality and security of the $SCIFI and $SPICE smart contracts by an independent third party, a contract audit was executed. Here are the details. SCIFI Finance Dec 9, 2020·2 min read

The audit was conducted by Chainsulting, a Germany-based smart contract audit team that has worked for renowned projects including MakerDAO, 1inch, DIA and many more. The scope of the audit included a range of tests around potential vulnerabilities and verifying claims about the smart contract usage and interactions. Both the $SCIFI and $SPICE contracts passed the audit in all categories.

“The overall code quality of the project is very good, not overloaded with unnecessary functions. They also used widely audited contracts which greatly benefits the security of the overall project. The main goal of the audit was to verify the claims regarding the security and usage of the smart contracts and deployment scripts. All claims have been verified by us and passed all tests.”

The full audit results can be viewed here.
Crypto Projects: Milestones Accomplished in 2020
Tags: Blockchain, Cryptocurrency, Smart Contracts

The term “smart contract” was first proposed by American computer scientist Nick Szabo. It refers to “a set of promises, specified in digital form, including protocols within which the parties perform on these promises”. Prior to the existence of blockchain technology, vending machines are mentioned as the oldest piece of technology that resembles the implementation of smart contracts.

In 2014 smart contracts re-emerged in Ethereum white paper. Vitalik and his team had a bold idea to bring programmability to blockchain. This opened the door to endless imaginability to a truly decentralized internet, and caught the attention of developers worldwide. Since Ethereum mainnet launched in 2015, this year marks the 5th year of smart contract functionality in the blockchain industry. Today smart contract development has never been more active as projects from all over the world are trying to solve real world problems with this young technology.

As the end of 2020 approaches, we revisited projects that are pushing today’s boundaries with the possibilities of smart contracts. While they are on long term missions to revolutionize various industries, let’s hear what their biggest achievements this year are.
How to fully repay your borrow and/or redeem your supply on Venus Protocol

How to fully repay your borrow and/or redeem your supply on Venus Protocol

I see users have been complaining about this since Venus launched, and I thought it would have been a quick fix by the Venus team. But since it’s already been 2 weeks, hopefully this quick guide will be helpful.

Repaying your borrow

Step 1 — Go to the smart contract of the vToken you want to repay on BSCScan

One way to do this is to try and borrow or repay on the Venus app and copy the address that MetaMask tries to interact with.

For easy reference, here’s a list of links to the vToken smart contracts, taken from Venus’ docs.

vSXP: 0x2fF3d0F6990a40261c66E1ff2017aCBc282EB6d0

vUSDC: 0xecA88125a5ADbe82614ffC12D0DB554E2e2867C8

vUSDT: 0xfD5840Cd36d94D7229439859C0112a4185BC0255

vBUSD: 0x95c78222B3D6e262426483D42CfA53685A67Ab9D

vBNB: 0xA07c5b74C9B40447a954e1466938b865b6BBea36

vXVS: 0x151B1e2635A717bcDc836ECd6FbB62B674FE3E1D

vBTC: 0x882C173bC7Ff3b7786CA16dfeD3DFFfb9Ee7847B

vETH: 0xf508fCD89b8bd15579dc79A6827cB4686A3592c8

vLTC: 0x57A5297F2cB2c0AaC9D554660acd6D385Ab50c6B

vXRP: 0xB248a295732e0225acd3337607cc01068e3b9c10

Step 2 — Write to repayBorrow() with value -1

Go to the “Contract” => “Write As Proxy”, “Connect to web3” then scroll down to “repayBorrow”, enter the value “-1” and write to the contract.

How does this work?

According to the Compound and Venus docs:

This doesn’t work for BNB though, as it requires the Maximillion contract to be deployed, which I believe Venus hasn’t done yet.

Redeeming your supply

Step 1 — Go to the smart contract of the vToken you want to repay on BSCScan

Same as step 1 above.

Step 2 — Get your supply balance

Go to the “Contract” => “Write As Proxy”, then scroll down to “balanceOf”, enter your wallet address and copy the response.

Step 3— Redeem your supply

Go to the “Contract” => “Write As Proxy”, “Connect to web3” then scroll down to “redeem”, paste the value from step 2 and write to the contract.

Example of barter trading
By: Nansy Dunne
Tags: Trading, Smart Contracts, Blockchain, Cryptocurrency, Barter

Hello! 👋🏻 Today we will tell you by example what a barter transaction is.

Barter is understood as the exchange of values ​​without the use of currency. During the Middle Ages, Europeans traveled all over the world to trade handicrafts and furs for silks and perfumes. Colonial Americans traded musket bullets, deer skins, and wheat.

When the money came about, barter became more organized and globalized. For example, if a country produces a lot of rice, that country can exchange it for another type of grain or fruit, textiles, or oil.

Barter between businesses often includes goods or services in exchange for advertising. A company can supply promotional materials and in return receive a certain amount of airtime.

A modern barter exchange is a platform for an organized search for counterparties for barter transactions, usually implemented in the form of a specialized site, the system of which provides an automatic search for options for exchanging goods and services, taking into account the expressed wishes.

🏆 Barter Smartplace creates a blockchain barter platform that will allow members to exchange any tokenized assets and liquid currency. The tokenized asset can subsequently be placed on the platform and sold or included in a barter exchange.

To conclude barter transactions, you just need to have funds in your bank account and agree to connect it to your Smartplace account to conclude subsequent transactions. Barter costs no more than 0.02% for each party, including Ethereum gas costs. If the dark pool is used for exchange, then the cost of the contract may be higher in exceptional cases.

The signing of a barter agreement by the parties is performed on a smart contract system with the replacement of data on the owners of assets in the relevant registers on the basis of a concluded legal contract. This is one of many examples of barter transactions.

✅ The Barter Smartplace platform is designed for international automated legal barter exchange, combining the traditional economy with decentralized finance.
