Future Technology

The distributed ledger technology (DLT) that underlies cryptocurrencies like Bitcoin and Ethereum is a promising new technology. But as with any new system, it comes with unique security considerations—ones that have received less attention than they deserve. As with many other technologies in the past, attackers will likely start small before attempting more sophisticated attacks; this post will help you understand what these attacks might look like on a blockchain-based network and how to defend against them.

The Digital Ledger

The digital ledger is a record of all transactions that have occurred on the network. It’s distributed across many nodes, which means that no one person or entity can control it. The ledger is immutable: once information has been added to it, it cannot be changed or deleted without being noticed by other participants in the network. In addition to these features making a blockchain tamper-proof, they also make it …

A Comparison of Consensus Algorithms

October 17, 2023November 9, 2023 - by Charlie Meneses

In the world of blockchain technology, there are numerous different consensus algorithms. Some of these are better suited to short-term considerations and others are better suited for long-term use. This article will cover each of the most popular consensus algorithms in detail, and help you decide which one best fits your needs.

Proof of Work

Proof of work is a system that requires a computer to find a solution to a mathematical problem before it can add its block to the blockchain. The difficulty of this task varies depending on how much effort is being put into mining across the network. In proof-of-work systems, miners must compete with one another in order to be awarded new bitcoins or transaction fees paid by users sending transactions across the network.

In addition, proof-of-work systems make it more difficult for someone (or some entity) who does not own any computing power themselves but …

Blockchain Smart Contract Development

September 19, 2023November 9, 2023 - by Charlie Meneses

The blockchain is a decentralized ledger that records digital transactions. It’s like a huge accounting book where transactions between two parties are recorded. The blockchain is shared among many users and it can only be updated by consensus of the network members. Because there’s no central authority (like a bank), blockchain technology has gained popularity as an alternative way to do business.

Smart contracts are self-executed with no need for human intervention.

Smart contracts are self-executed with no need for human intervention. They are software code that can be executed on a blockchain, where they automatically implement their terms when certain conditions are met.

Smart contracts are used to facilitate, verify and enforce many types of contractual clauses. For example:

Escrow services — A third party holds funds in escrow until both parties agree it’s appropriate to release them (e.g., after delivery). This reduces the risk that either party will

Understanding The Blockchain Through History

August 15, 2023November 9, 2023 - by Charlie Meneses

Bitcoin is one of the most talked-about topics in the world today. Everyone wants to know what it is, but few people understand it. This isn’t surprising, since Bitcoin was invented as a way to replace government-backed currencies with a completely virtual alternative that was not backed by any country or central bank. Still, even though most people have never used Bitcoin themselves or even interacted with anyone who has used it, they have heard about it—and many people are skeptical about whether digital currencies will ever catch on.

What Is A Blockchain?

A blockchain is a digital record of transactions. It’s also a decentralized ledger technology and distributed database, but let’s start with the basics.

A blockchain is an electronic spreadsheet that stores data in chronological order. Each entry on the spreadsheet contains two things: information about either an individual transaction (like when someone sent some bitcoin) or metadata …
