4 major blockhains for smart contracts
October 20, 2022

Blockchain technology quickly becomes a favorite for many industries and applications, including smart contracts. Ethereum has been leading the pack with its unique model that allows developers to build applications on top of its blockchain. However, one could also use other platforms for this purpose. Here is our list of 4 significant blockchains for smart contracts.

Smart Contract Ethereum

The Ethereum platform has many advantages over Bitcoin. The most significant one is that it allows developers to build and deploy decentralized applications. Ethereum is a blockchain-based decentralized platform that runs smart contracts. Its applications run exactly as programmed without any possibility of downtime, censorship, fraud, or third-party interference. At least on paper.

With this technology, you can create new types of businesses and workflows. For example, if you want to hire someone on your team or pay them in the future, there’s no need for an intermediary like PayPal or Payoneer. Instead, you can easily set up a contract with an employee where they are paid after completing their tasks within a certain period and conditionally based on their performance!

Hyperledger Fabric

Hyperledger Fabric is a blockchain framework that allows you to build and deploy private blockchains. The Linux Foundation created it in 2017, which also maintains other blockchain frameworks such as Hyperledger Sawtooth and Hyperledger Iroha.

The group behind Hyperledger Fabric has been working together since 2015. Their primary purpose is to advance open-source technology for blockchain applications. They have launched multiple projects within this framework, including but not limited to the following:

Fabric Composer – A visual tool for building blockchains

Cello – A deployment system for running networks with Docker containers

EOS & Smart Contracts

EOS is a blockchain-based operating system that focuses on commercial-scale decentralized applications. The primary industries are the fields of industrial scale and decentralized autonomous corporations (DACs). EOS aims to be a platform for decentralized applications and offers some tools for developers. Builders can use Antelope – formerly EOSIO – software to create their blockchain, which they can then build their apps on top of.

EOS can support thousands or millions of users who want to interact with its network simultaneously. It is designed to be scalable, flexible, and extensible. It does this by using Delegated Proof-of-Stake (DPoS) consensus algorithm instead of the Proof-of-Work (PoW), which Bitcoin has used since 2009. 

That means that transactions are validated by ” witnesses ” groups rather than miners. The approach results in more efficiency when sending money from one person’s account directly into another’s account. All without having any middlemen involved, such as banks or credit card companies

R3 Corda

R3 Corda is a blockchain platform for financial institutions. It’s not a public blockchain. Instead, it was developed by R3, a consortium of banks and financial institutions. The idea behind Corda is that parties can use it to process transactions between companies in this group without going through a central authority.

However, unlike most other platforms we’ve mentioned, R3 Corda isn’t open-source software. As a result, the code isn’t available for anyone to see what it does or how it works. In addition, while people are working on building applications on top of Corda (such as Hyperledger Fabric), the core team can’t directly support these apps. Moreover, the apps may not work as advertised once you deploy them into production.

Chances of anything going utterly wrong are minimal, though.

There is more than just Ethereum for smart contracts

While Ethereum is the most popular blockchain for smart contracts, other blockchains are also being used. Hyperledger Fabric, Corda, and Quorum are three examples of platforms that allow you to create and execute smart contracts on their respective networks. 

These platforms have different features, such as privacy or scalability. They also have different limitations. Understanding your needs is essential before deciding which one is right for you.

Conclusion

Ethereum is the most well-known blockchain for smart contracts, but other options exist. 

Hyperledger Fabric is one of these alternatives. It also uses a permissioned network and supports multiple programming languages (Go, Java, NodeJS). 

However, it differs from Ethereum in using a consensus mechanism called “consensus by committee” rather than proof-of-work or proof-of-stake. 

Other networks may use similar or other unique consensus algorithms. Always review the underpinning technology before committing resources to a network that may not suit your needs.

The Grand Chessboard♟️

The Grand Chessboard or The Plan for WW3 according to Zbigniew Brzeziński📚

On June 4, 2009, Zbigniew Brzezinski, U.S. national security advisor:

"This crisis will never end until we achieve our goals. Our goals are well known to you - 👉a one world government

That's what we need. And it will be formed whether you like it or not. It's going to get worse and worse from here. 👉It's not a crisis - it's controlled chaos. Society must not only accept the idea of a one-world government, but see it as its only salvation, for this we need wars, famines and epidemics all over the world."

NOW...

It's YOUR choice whether you play the game!
THEY can NOT force you to play.
It has to 💯% YOUR choice by FREE WILL.

The Rothschild Central Banking Hidden Money Matrix👀

🚨The Rothschild Central Banking Hidden Money Matrix: How Big Banks and Big Government Steals Your Wealth Through the Federal Reserve Scam🚨

A 30 min documentary on how the Rothschilds, Rockefellers, and Globalist Elites created the U.S. Federal Reserve to enslave American citizens and bankrupt our nation to destroy it from within.

People are finally waking up to the realization that our modern monetary system is nothing more than a massive fraudulent parasitic scheme designed to siphon wealth from hardworking citizens to banks and government elites and they've been rising up to fight back.

The Federal Reserve, despite its official-sounding name, is a private banking corporation owned by major central bankers who live in England, it is NOT a government agency.

Created in 1913, the same year the income tax amendment was passed (no coincidence), this system enables the continuous theft of your purchasing power through a complex web of Treasury bonds, Federal Reserve checks written from empty ...

🚨 CryptoQuant Founder Slams X Over Bot Spam and Crypto Suppression 🚨

Ki Young Ju, CEO of on-chain analytics firm CryptoQuant, publicly accused X of throttling legitimate crypto content while letting paid bots flood the zone—7.7 million “crypto”-tagged posts in one day, a 1,200 % spike that he says triggered algorithmic shadow-bans on real accounts.

🔑 Key points

🔹 Bot tsunami: On-chain social metrics show >7.7 M daily “crypto” keyword posts; Ju claims AI-generated spam is gaming X’s own paid-verification gate to “pay to spam.”

🔹 Algorithmic blowback: Automated moderation, unable to separate wheat from chaff, suppresses organic CT reach; Ju: “It is absurd that X would rather ban crypto than improve bot detection.”

🔹 Product pushback: X product lead Nikita Bier fired back that CT “kills its own reach” by over-posting low-value memes (“gm” replies), exhausting daily quota before substantive tweets.

🔹 Platform paradox: Despite hostilities, X ...

🔮Pyth Hodlers/Stakers, Please Show Some Love💖

👉Please like and support my recent post in the Pyth Dao Forum:

Building on the transparency and tiered-buyback ideas, we should look at Capital Efficiency. If the DAO is going to hold a massive reserve of $PYTH, we should ensure it’s either (a) rewarding the most active stakers to encourage governance or (b) being put to work as Protocol Owned Liquidity to improve market depth.

Here are several suggestions:

1. The “Real Yield” Staking Model
Currently, the proposal focus is on buying back $PYTH to build a reserve. To increase token demand, you could suggest distributing a portion of the buyback value as “yield” to active governance stakers.

The Idea: Instead of just holding 100% of the purchased $PYTH in a silent reserve, a percentage (e.g., 20% of the monthly buyback) could be distributed to users who have locked their $PYTH and actively voted in the DAO.

Why it works: This creates a “Real Yield” narrative similar to protocols like GMX or Aerodrome, where token value is directly tied to protocol cash ...

🚨David Grusch on The Megyn Kelly Show🚨

Earlier this week, UFO/UAP whistleblower David Grusch appeared on The Megyn Kelly Show for a brief but revealing interview. During the conversation, Grusch named individuals he claimed were involved in managing the alleged UFO/UAP Legacy crash retrieval program, statements that immediately drew attention across the disclosure community.

Most notably, Grusch asserted that former Vice President Dick Cheney played a central role in overseeing the program. Cheney’s name has circulated within UFO/UAP research circles for years, but this marks the first time it has been spoken publicly by a former intelligence official who claims direct knowledge of the issue. It is also notable that just weeks ago, journalist Ross Coulthart independently referenced Cheney in a similar context, lending additional weight to the consistency of these claims.

Grusch also named former Director of National Intelligence James Clapper, stating that Clapper was not only aware of the crash retrieval issue, but managed it and helped place individuals into key roles, both publicly and behind the scenes. These are serious assertions that warrant scrutiny and further investigation, given their potential implications for disclosure.

Please watch the full interview and consider its significance within the broader context of the disclosure conversation. Please note that the interview concludes with a paid promotional pitch, and Grusch does not provide any additional comments after the pitch.

Stellar CEO Reveals Where Real Opportunity Lies in Crypto Market: Details

In a recent tweet, Stellar Development Foundation (SDF) CEO and Executive Director Denelle Dixon defines what "real opportunity" is in blockchain as a new financial future beckons.

The SDF CEO was reacting to a recent Bloomberg report on Bank of New York Mellon Corp (BNY), Nasdaq, S&P Global and iCapital participation in a new $50 million investment round by Digital Asset Holdings. This comes as some of Wall Street’s biggest names embrace the technology that underpins cryptocurrencies to handle traditional assets.

Reacting to this development, Stellar Foundation CEO Denelle Dixon stated that every blockchain investment is a bet on a different financial future. Dixon added that seeing banks explore blockchain technology validates what has been known over the years.

Real opportunity defined

While Wall Street’s biggest names betting on blockchain might be one of the most significant adoption milestones in the digital asset market, Dixon defines what real opportunity is and what it is not.

According to the SDF executive director, real opportunity is not replicating old systems on new rails but rather building open networks that fundamentally expand global finance participation.

"But the real opportunity isn’t replicating old systems on new rails—it’s building open networks that fundamentally expand who gets to participate in global finance. That’s the opportunity," Dixon tweeted.

At the Meridian 2025 event, Stellar outlined its long-term privacy strategy, committing to investing in critical privacy infrastructure and building foundational cryptographic capabilities.

Stellar eyes privacy upgrade

A new protocol upgrade is on the horizon for the Stellar network: X-Ray, which lays the groundwork for developers to build privacy applications on Stellar using zero-knowledge (ZK) cryptography.

The protocol timeline testnet vote is anticipated for Jan. 7, 2026, while the mainnet vote is expected for Jan. 22, 2026.

XDC Network's acquisition of Contour Network

XDC Network's acquisition of Contour Network marks a silent shift to connect the digital trade infrastructure to real-time, tokenized settlement rails.

In a world where cross-border payments still take days and trap trillions in idle liquidity, integrating Contour’s trade workflows with XDC Network Blockchains' ISO 20022 financial messaging standard to bridge TradFi and Web3 in Trade Finance.

The Current State of Cross-Border Trade Settlements

Cross-border payments remain one of the most inefficient parts of global finance. For decades, companies have inter-dependency with banks and their correspondent banks across the world, forcing them to maintain trillions of dollars in pre-funded nostro and vostro balances — the capital that sits idle while transactions crawl across borders.

Traditional settlement is slow, often 1–5 days, and often with ~2-3% in FX and conversion fees. For every hour a corporation can’t access its own cash increases the cost of financing, tightens liquidity that could be used for other purposes, which in turn slows economic activity.

Before SWIFT, payments were fully manual. Intermediary banks maintained ledgers, and reconciliation across multiple institutions limited speed and volume.

SWIFT reshaped global payments by introducing a secure, standardized messaging infrastructure through ISO 20022 - which quickly became the language of money for 11,000+ institutions in 200 countries.

But SWIFT only fixed the messaging — not the movement. Actual value still moves through slow, capital-intensive correspondent chains.

Regulated and Compliant Stablecoin such as USDC (Circle) solves the part SWIFT never could: instant, on-chain settlement.

Stablecoin Settlement revamping Trade and Tokenization

Stablecoin such as USDC is a digital token pegged to the US Dollar, still the most widely used currency for trade, enabling the movement of funds instantly 24*7 globally - transparently, instantly, and without the need for any intermediaries and the need to lock in trillions of dollars of idle cash.

Tokenized settlement replaces multi-day reconciliation with on-chain finality, reducing:

  • Dependency on intermediaries
  • Operational friction
  • Trillions locked in idle liquidity

For corporates trapped in long working capital cycles, this is transformative.

Digital dollars like USDC make the process simple:

Fiat → Stablecoin → On-Chain Transfer → Fiat

This hybrid model is already widely used across remittances, payouts, and treasury flows.

But one critical piece of global commerce is still lagging:

👉 Trade finance.

The Missing link is still Trade Finance Infrastructure.

While payments innovation has raced ahead, trade finance infrastructure hasn’t kept up. Document flows, letters of credit, and supply-chain financing remain siloed, paper-heavy, and operationally outdated.

This is exactly where the next breakthrough will happen - and why the recent XDC Network acquisition of Contour is a silent revolution.

It transforms to a new era of trade-driven liquidity through an end-to-end digital trade from shipping docs to payment confirmation – one infrastructure that powers all.

The breakthrough won’t come from payments alone — it will come from connecting trade finance to real-time settlement rails.

The XDC + Contour Shift: A Silent Revolution

  • Contour already connects global banks and corporates through digital LCs and digitized trade workflows.
  • XDC Blockchain brings a settlement layer built for speed, tokenization, and institutional-grade interoperability and ISO 20022 messaging compatibility

Contour’s digital letter of credit workflows will be integrated with XDC’s blockchain network to streamline trade documentation and settlement.

Together, they form the first end-to-end digital trade finance network linking:

Documentation → Validation → Settlement all under a single infrastructure.

XDC Ventures (XVC.TECH) is launching a Stable-Coin Lab to work with financial institutions on regulated stablecoin pilots for trade to deepen institutional trade-finance integration through launch of pilots with banks and corporates for regulated stable-coin issuance and settlement.

The Bottom Line

Payments alone won’t transform Global Trade Finance — Trade finance + Tokenized Settlement will.

This is the shift happening underway XDC Network's acquisition of Contour is the quiet catalyst.
