Deploy Your First Smart Contract on Loom Network Using Remix

Introduction to Loom Network:

Loom Network is a platform to help the Ethereum scale. Loom Network provides a Layer 2 solution that uses Ethereum as it’s the base layer. Using Ethereum as a base layer means base chain assets like ERC20 & ERC721 tokens can have security guarantees of the Ethereum.

The loom is the perfect solution for building scalable applications with almost no transaction cost and very less amount of time for transaction confirmation.

If you don’t know more about the Loom Network and are curious to know, then you can check this handy guide where you can get more ideas about the Loom Network.

Without wasting time, let’s go through the process of deploying smart contracts on the Loom Basechain.

How to Deploy Smart Contract on Loom Chain:

It’s easy to deploy smart contracts on the loom.

Steps to deploy Smart Contract on Loom:

Integrate Remix with Loom

Writing your Smart Contract

Deploy Smart Contract on Loom from Remix IDE.

It’s that simple! Isn’t it?

Step 1: Integrate Remix IDE with Loom

To integrate Remix with loom it requires services that proxies JSON RPC call to Loom. For that, Loom had built a small JSON RPC Proxy. So, here we will install and configure it with the Remix IDE to deploy our smart contract on Loom.

Prerequisites to install JSON RPC Proxy:

 Node.js 10 or higher(recommended v10.15.3)

Yarn

Git client

 1. Clone the JSON RPC Proxy repository:

Open a terminal, cd into your project directory and execute below command:

git clone https://github.com/loomnetwork/loom-provider-json-rpc-proxy

2. Install Dependencies and Build the Proxy:

For that run below command,

cd loom-provider-json-rpc-proxy/ && yarn install && yarn build

3. Configure the Proxy:

You need to configure a proxy to connect to Loom Testnet or Loom Basechain. For that, you need to set the following environment variables,PORT: port on which proxy listens for incoming requests. The default port is 8080. CHAIN_ID: Network Id you want to connect to. default for Mainnet & extdev-plasma-us1 for Testnet. By default, it will connect to Loom Mainnet. CHAIN_ENDPOINT: the address of the endpoint. The default value is wss://plasma.dappchains.com.Run below command to run proxy against Loom Testnet.

PORT=8545 CHAIN_ENDPOINT="wss://extdev-plasma-us1.dappchains.com" CHAIN_ID="extdev-plasma-us1" node .

Run below command to run proxy against Loom Basechain. Make sure deploying smart contracts on Loom Mainnet isn’t free. To deploy a smart contract on Loom Mainnet you need to whitelist your address, which will cost you around 1400 Loom per year ATM.

node .

Step 2: Writing your Smart Contract

Here is our Smart Contract example. It is a very simple smart contract that stores string messages and retrieve it from smart contracts. This is just for demo purposes. You can also use your smart contract code.

pragma solidity ^0.4.25;

contract HelloWorld {

  // Define variable message of type string

  string message;

  // Write function to change the value of variable message

  function postMessage(string value) public {

      message = value;

  }

  // Read function to fetch variable message

  function getMessage() public view returns (string){

      return message;

  }

}

Step 3: Deploy Smart Contract on Loom

First of all, we need to configure Remix to use Loom JSON RPC Proxy. For that open Remix Editor. Click on the Run menu and then select the Environment as Web3 Provider.

Now you are good to deploy our solidity Smart Contract to Loom Network. Paste below smart contract code into Remix. Select the appropriate compiler version and compile a smart contract by clicking the Compile button.

After compiling a smart contract you can deploy your smart contract by just clicking the Deploy button.

Conclusion:

Cheers. You just deployed your first smart contract code on the Loom network. I hope from now onwards you can deploy smart contracts on the Loom Network. If you have any confusion feel free to comment below.

Stay tuned with Yudiz Solutions!

Annotated edition of May 17 Week in Ethereum News

As noted last week, I’ve started to think of this as the “Eth holder, but doesn’t work in the industry” edition, so we kick it off with the high-level things I’d read beyond just what you can read.  So, for example, Gnosis/OpenEthereum is picking up the Parity client, but you can see that without me highlighting it.

So here’s my highlight of high-level things for Eth holders.

Some interesting findings in ConsenSys’s eth2 staking survey

Visa patent shows they are building on Ethereum

Building on ethtrader’s DONUT, Reddit unveils community points for r/fortniteBR and r/cryptocurrency subreddits. At the moment, 9000 wallets created for fortnite and just 2100 for r/cryptocurrency. Currently on Rinkeby testnet with plans to move to mainnet.

JPMorganChase decides to bank Coinbase and Gemini

ErisX launches ETH futures, physically delivered, monthly and quarterly contracts

dydx’s BTC/USDC perpetual with 10x leverage is open to the public

This BTC/USDC perpetual matters because the crypto market has been overtaken by YOLO gambling on centralized exchanges that probably trade against you as they know liquidation points and no one else does.   Not a surprise, dydx’s founder says this is already the #1 most traded DeFi.   Centralized exchanges get hacked all the time - not your keys not your crypto.  DeFi is an improvement.

We finally have Eth futures!  And they’re physically delivered, which is good.  Though physical delivery requirements can lead to strange consequences (eg,negative price of oil last month!), it keeps traders honest and moors the price to the actual asset.

JPMorganChase finally banking some crypto clients is an important step for the space.

Reddit is testing letting subreddits govern themselves and pay for things using an Eth token.  Very cool

Visa patented their method of digitizing dollars on Eth at the same time that their chairman said at a conference that “digital currencies could be additive to the payments ecosystem” and that they “supported” them.

In September 2018, the same Visa chairman said that “[blockchain] isn’t really at its core, for us, a good technology.”

It’s interesting that even as the crypto market continued to wane, Visa realized they needed to try to get ahead of the curve.   Crypto isn’t dead.

Eth1

Geth v1.9.14 – unindex and save disk space

OpenEthereum v3. Formerly the Parity client. Support for eth/64, breaking database changes to save disk space. Deprecating light client, auto updater, and private transactions

cross-client consensus tests v7

Latest core devs call. Beiko’s notes from the call, largely around EIPs for next hard fork, eg: 2315 (evm subroutines), 2537 (precompile for curve in eth2), 2046 (reduce gas for static calls to precompiles) and 2565 (repricing the 198 precompile)

EVM+384 bit arithmetic as an alternative to EIP2537’s precompile

Discussion of a second method for resource accounting alongside gas: oil from Suhabe Bugrara, separately formulated as karma from Martin Swende. Or a counterproposal from Vitalik: per account gas limits

The case for Eth-collateralized tokenized gas at the protocol level

So the first real release of the fka Parity client.  Very cool, client diversity is important and to my knowledge there are no large scale miners running anything but the Go and Rust clients, so this is important.

What’s up with the “second method of resource accounting alongside gas?”  The idea is that stateless Eth will need a substantially different gas schedule for block witnesses, yet we don’t want to break existing contracts.  We want backward compatibility without overly complicating the dev experience.  Not an easy problem, hence the debate about the best way to do it.

Meanwhile there’s a bit of a debate about some of what goes into the next hard fork.  Relatively normal stuff, some folks think we should stop doing all these precompiles (eg, bit arithmetic proposal), others think we should only do the general precompile EIP

Eth2

Latest what’s new in eth2, featuring Ben’s thoughts on timelines

Latest eth2 implementer call. Notes from Ben and Mamy, targeting June for the multi-client testnet

Schlesi testnet: Teku is fully participating and Nimbus is almost fully syncing, though there was a chain split this weekend

Proof of custody through occasional checks and slashing

Stethoscope: networking test suite

Idea from Justin Drake on putting price feed oracles in eth2 via validators, and a counter-proposal from Vitalik Buterin

The Schlesi testnet went down, but overall it has been quite stable.  Nothing terribly unexpected for a testnet, and Lodestar will soon be the 5th client to join up.  Slow and steady progress.

Price feed oracles got quite a bit of pushback, I think some of this is because stablecoins are having their second renaissance - something I’ll touch on later.

Proof of custody (ie, that you as a validator hold the data you say you do) through a Truebit-like game: to prevent lazy attestations, the protocol will guarantee false things, and if validators don’t point it out, then they get slashed.  

Layer2

What are the true finality guarantees of state channels? Depends on liveness of layer 1 chain

We often say that state channels offer “instant finality” but this is a bit of a shorthand to say that it offers “instant finality” assuming that the underlying basechain has “liveness” (which is just blockchain-speak for “is producing blocks”)

Mainnet testing with your own node using Brownie

headlong: ABI v2 and RLP for the JVM

EthPM v3 – spec for v3 of Eth package manager is in last call

12 bugs found by Trail of Bits’ Crytic tool using 90+ detectors

Verifiable randomness on-chain using the Chainlink VRF

Austin’s eth.build explainer vid is great.  Truly recommended - as a community we should be trying to get this in front of many devs as possible.   

How long until someone wins a hackathon with eth.build + oneclickdapp or dapphero?   Seems possible.

Chainlink VRF seems quite cool; PoolTogether is already integrating it.

Ecosystem

Some interesting findings in ConsenSys’s eth2 staking survey

A guide to building with MACI – an anti-collusion demo using SNARKs

And Tornado did burn the admin keys between then and now.

Where to use the Baseline protocol: sharing business process automation with counterparties

Brave releases Mjolnir tool for easy deploying and benchmarking permissioned Eth chains

Brave is going to move their token to a separate chain, presumably with a bridge.  Doesn’t seem like terrible news to me, if you have a small amount of BAT, you don’t need a strong censorship-resistance guarantee.

Application layer

Building on ethtrader’s DONUT, Reddit unveils community points for r/fortniteBR and r/cryptocurrency subreddits. At the moment, 9000 wallets created for fortnite and just 2100 for r/cryptocurrency. Currently on Rinkeby testnet with plans to move to mainnet.

Dfinity’s first Swiss employee Robert Lauko now working on Liquity stablecoin, low collateralization with algorithmic liquidation via stability pool

“Augur v2 core contracts are finalized and in a code-freeze state, and the trading UI is undergoing performance testing”

Aave changes its interest rate model. Inflection point in the curve now 8% and 90% usage.

Kyber hit 1 billion USD worth of trades

Brave at 14m MAU/5m DAU

Sai successfully shut down on May 12 and now is redeemable for ETH

Hasu: the future of cryptomoney is central banking. An analysis of Maker’s options and decisions

Utah County (Provo) in Utah offering marriage licenses certified with the hash on Eth mainnet

dydx’s BTC/USDC perpetual with 10x leverage is open to the public, and compares centralized and decentralized perpetual markets

Lots of cool stuff, some of which touched on above.   Utah County is not the first local government to do something like this, but as far as I could tell, it was new.   That must have been a hard sale with the crypto hope at a relative nadir.   Amusingly their site was not https (not that I should judge, I’ve been lazy about that myself, usually do to my cheapness in finding hosts...ahem Tumblr)

Brave growth keeps going.  It really is a superior product, it always surprises me that there are some in crypto who doesn’t use it.

One interesting trend is that we’re having a bit of a renaissance in projects trying to compete with Maker.  Of course Synthetix has had quite a bit of success, though previous rounds contained some laughable attempts (Basecoin).   Stablecoins have a large design space with lots of risks to tradeoff.  I think the new wave of stablecoin designs has some interesting ideas.  I think there’s plenty of space for more people to be successful, though I think plenty of folks are underrrating how hard it will be to compete with Maker.

Overall this felt like a good week for the app layer section, and my usual arbitrary “how much is DeFi? metric comes in at 6/10

Tokens/Business/Regulation

ErisX launches ETH futures, physically delivered, monthly and quarterly contracts

Now ~2300 WBTC on Eth versus 900 BTC on Lightning

RAC’s $TAPE launched on Zora and went from $20 to $1000. $TAPE is a token redeemable for a special edition cassette of RAC’s latest album. Interesting new model for artists to capture value

I guess “days, not weeks” dies as an Ethereum meme?   Or maybe it’s like wooks and TwoWeeks, and it will live forever.

(if you don’t catch the reference, there before Eth shipped in july 2015, there was 18 months of Bitcoiners claiming that it was vaporware that was impossible and would never ship, and the eternal answer was always that the ship date was “two weeks” away....which became “two wooks” because the internet is wonderfully weird).

Meanwhile BTC keeps migrating to ETH, as the Bitcoin chain is too limited and fundamentally unsustainable so if you want to do anything with your orange memecoin, then you have to use Ethereum.

Loved seeing RAC’s $TAPE do well.  While critics say this is gimmicky and perhaps not replicable, I actually tend to think the opposite.  Many artists have huge fans who would pay insane amounts - artists have never done a great job at giving their fans new experiences and capturing value.  

General

JPMorganChase decides to bank Coinbase and Gemini

Wired’s story on MalwareTech/Marcus Hutchins, from stopping WannaCry to FBI arrest

the main idea in HALO snark construction

Open cryptography problems: improving stealth addresses and ideal vector commitment

I love how the general section is such a mismash of the deepest crypto things and then human interest stories like about Marcus Hutchins.  The Wired writer bought his story - I tend to think it’s probably slightly more complicated

I’ve been trying to figure out what to do with the calendar.  I’m not excited about virtual conferences and VR.  But maybe some of you are?

That’s all for this week in the annotated edition.  If you made it this far, would you tweet about it or RT this?   https://www.evanvanness.com/post/618575234233204736/annotated-edition-of-may-17-week-in-ethereum-news

Blockchain Interoperability Solutions

The majority of interoperability solutions up till recently were mainly focused on chain interoperability across public blockchains, thereby using crypto-directed tools like sidechains (or relay chain), notary schemes and timed hash-locks. The focus however has increasingly shifted towards solutions for interoperability between private networks and/or between private networks and public blockchains.

One way to solve interoperability is to use a separate blockchain as a bridge to facilitate cross-communication. Essentially, this is a third blockchain that sits in the middle of the two blockchains and maintains a cryptographically secured timestamped ledger of the transactional and messaging activity between the two. Interoperability tools that are used range from hub and spoke, decentralised finance (DeFi) and general purpose bridges.

Another way to facilitate interoperability between systems is with off-chain or middleware systems. This so-called non-blockchain interoperability approach uses tools including atomic swaps, oracles and state channels.

Blockchain Interoperability projects

A growing number of interoperability projects have entered the scene to try to bridge the gap between the various blockchains. Their aim is to facilitate interaction between networks and ensure the concept of decentralisation is fully realised. Depended on the interoperability solutions these can be used for activities like decentralised asset exchange and decentralised message exchange. Interesting projects are Chainlink, Cosmos, Hybrix, Polkadot and Wanchain. Other examples include Aion, Ark, ICON, Transledger, and Overledger.

Chainlink

Chainlink is a decentralised oracle network, an interoperability solution to facilitate secure and trustless communication between all disparate blockchain systems. The resources mostly revolve around off-chain data to trigger smart contracts and settlement outputs like established payment systems and cloud backend. This standalone function is important for many blockchains that don’t have to interact with other blockchain protocols but do need access to externals inputs and outputs.

Chainlink nodes are able to format messaging and data from public APIs into a readable format for smart contracts. These nodes can connect to any API, whether it is a blockchain, enterprise system, Web API, or IoT device.

Chainlink is sometimes working in combination with other interoperability protocols. Chainlink has already announced partnerships with Polkadot and Ethereum to provide off-chain data to their networks. Wanchain is integrating with Chainlink to provide off-chain data to their on-chain smart contracts.

Cosmos

One of the most prominent interoperability solutions is Cosmos, very much focused on its Cosmos SDK platform. Cosmos aims to act as an ecosystem of blockchains that can scale and interoperate with each other. Cosmos is a smart contract platform that has prioritized interoperability as a critical component of their blockchain design. Their architecture is based on the so-called ‘hub-and-spoke’ system whereby a series of ‘spoke’ chains connect to a ‘central’ hub by means of inter-blockchain communication.

Cosmos is heavily reliant on validators to provide interoperability. It makes use of the so—called Byzantine fault tolerant (BFT) consensus algorithm and uses both member chains and Peg-Zones for existing chains to improve the overall ecosystem. Their end goal is to create an ‘internet of blockchains’ – a network of blockchains that can communicate with one another in a decentralised way.

The implementation of the IBC (Inter Blockchain Communication) protocol is scheduled for this year 2020. Cosmos will use the IBC protocol to allow communication between a central hub and the chains linked to the network, also called Zones. It will first only concern the interoperability of chains built on top of Cosmos SDK platform.

Hybrix

Hybrix is an open-source cross-chain solution aimed to make it easier to make cross-chain transactions, and also increase the level of ease for developers who want to offer multi-chain platforms. For that purpose Hybrix is developing an “HY” token. Each token represents an identical block of a chain and can be used to reconcile data across the entire crypto complex. Tokens form as bridges that allow transactions to be conducted on either a single chain or multi-ledger systems. Since Hybrix utilizes existing languages to build its protocol and interface, there’s no need to acquire new coding languages to use its system. Hybrix has amplified its capacity to adapt 27 major blockchains and more than 400 tokens.

Polkadot

Another project is Polkadot, which facilitates transactions and data exchange, aiming to promote interoperability between blockchains. It uses the DPoS algorithm and employs required validators which can lead to a certain degree of centralization .

The concept at Polkadot is quite similar to that of Cosmos. It allows communication between the relay chain and the parachains of Polkadot’s network. By using Parachains and Bridgechains, this approach enables to transfer both value and data. Additionally, scalability will be taken to a whole new level by running multiple parallel chains. This is a bit different from other projects which are looking to bridge the gap between blockchains as well.

The launch of their mainnet is planned for this year (2020). As for interoperability, there are no precise timelines regarding their protocols for chains implementation.

Wanchain

The Wanchain network allows interoperability between very heterogeneous blockchains like Bitcoin, Ethereum and EOS. Wanchain aims to link and facilitate communication between the different blockchains as much as possible.

Wanchain is already functional and allows communication and exchange of value and data between public and private blockchains through storeman nodes and the T-Bridge framework. The storeman node system combines two cryptographic concepts that ensure security and confidentiality of network transactions: secure multi-party computation and “Shamir’s secret sharing”.

The Wanchain project recently announced the integration of EOS blockchain and the implementation of the T-bridge framework. Wanchain’ s next challenge is to fully decentralise its network. This is planned to be finalised in 2022.

Other interoperability offerings

And there are many more interoperability projects including Aion, which is working towards integrating artificial intelligence in its consensus model. Or Ark which uses Smartbridge to link existing chains, and will also allow for the transfer of both data and value. And the Loom Network, which uses its DPoS blockchain Basechain to connect and transfer value among several blockchains, including Bitcoin, Ethereum, and Binance. A rather unknown but interesting player is Block Collider. Its proof-of-distance (PoD) consensus algorithm ensures that ledgers can operate with one another. It is also the only project that, in its current form, requires any validators.

Liquid Bitcoin with Adam Back & Samson Mow - WBD224

Location: Zoom

Date: Friday 15th May

Project: Blockstream

Role: CEO & Chief Strategy Officer

Bitcoin: decentralised, permissionless, censorship-resistant and unconfiscatable. Unique properties which make it a unique form of money

For Bitcoin to keep growing, these features mustn't be compromised. However, scaling solutions for Bitcoin, may trade off some of these features for other benefits.

With the vast majority of the community in agreement that block sizes must remain small to maximise decentralisation, Bitcoin is best scaled using layered solutions. The Liquid Network, like the Lightning Network, is a layer two solution that, by sacrificing some aspects of decentralisation and censorship resistance, can improve speed and scalability.

Liquid is a project spearheaded by Blockstream and is aimed at traders, exchanges and market makers to offer faster and more confidential transactions than the Bitcoin basechain. It also adds the ability to build tokens on the network.

In this interview, I talk to Adam Back and Samson Mow Blockstream's CEO & Chief Strategy Officer. We discuss The Liquid Network, the tradeoffs between Liquid and the basechain, how it differs from Lightning network and tokenised securities.
