Epicenter - Learn about Crypto, Blockchain, Ethereum, Bitcoin and Distributed Technologies

We often take data storage for granted, but the rise of centralised storing facilities (i.e. AWS, GCP, Azure, etc.) hangs over like Damocles’ sword. When it comes to blockchains, full nodes store that network’s complete data history. Even if storage costs are set to decrease as technology evolves, so do blockchains accumulate more data over time. An interesting solution would be to create a decent...

Building a truly decentralised, peer-to-peer network, based on a built-in identity system, limits the ecosystem’s interoperability with the outside world. Onboarding developers and users to Urbit was only the first hurdle. On-ramping crypto was a whole different & daunting task. Uqbar set out to build an execution layer on top of Urbit, enabling smart contracts, which would ultimately settle, via...

Considering the abundance of cryto projects launching constantly, making sound investment decisions requires both ample experience in the space, as well as a reliable network. Predicting future trends in such a volatile industry is a skill very few possess, especially since narratives evolve at a rapid pace. Ryan Zurrer is one of the OG participants and investors in the blockchain industry, with a...

When it comes to scaling blockchains, there are 2 main types of off-chain solutions: sidechains and L2s (i.e. rollups, state channels). These are all intended to scale monolithic L1 blockchains. However, the core functional layers of a blockchain could also be reinvisioned as customisable building blocks. This idea led to the creation of modular blockchains, which handle execution, consensus and d...

Scientific research & publishing are gruelling tasks that extend outside the scope of science itself. Centralised publications abound in archaic practices that span from submitting a paper to getting it peer-reviewed and finally published, process which may take even up to years. In addition, research requires funding from very early stages of pursuing an idea, all the way to its finality (i.e. cl...

While Part 1 (#486) focused on the technological advancements that allowed proofs to be generated in a practical manner, lowering both the time and the hardware requirements, in this episode, we take a closer look at the use cases of different types of zk rollups and how they could promote blockchain mass adoption. Polygon's zk EVM equivalence, coupled with low transaction fees, promise a friction...

With the upcoming launch of Polygon's zkEVM mainnet, L2s are undoubtedly a huge narrative that is unfolding in 2023. It is time to take a step back and recognise the incredible amount of effort that has gone into researching and building L2 scaling solutions in general and zk rollups in particular. Tech-wise, we barely scratched the surface of general purpose processors that can handle zk circuits...

Layer 2 scaling solutions are widely regarded as the next step forward in the mainstream adoption of crypto as they enable higher throughput and lower transaction fees. Coinbase’s recent announcement of building an optimistic rollup solution called Base is proof (no pun intended) that major centralized actors view this as an opportunity to onboard new users in a decentralized crypto economy. The f...

Building a blockchain from the ground-up is a daunting task in itself, one that should not be a concern when designing an end-user application. Moreover, as Web3 aims to move away from centralized vertical scalability towards a multi-chain decentralized environment, horizontal scalability and cross-communication should represent a standard. While Cosmos solves the latter, deploying application-spe...

Web3 has always been criticised for its not so friendly user experience. While one might argue that it requires a mere learning curve, similar to that of e-mail services when first introduced, Web2’s ease of use has become the norm. Account abstraction and smart contract automation are just 2 solutions for unlocking higher flexibility in transaction execution logic. These backend improvements, alo...

The Metaverse has taken the world by storm in 2021 and even though many have and are still opposing it, the fact that we are spending the majority of our lives online is an undeniable truth. The boundaries between physical and digital worlds are slowly eroding away. Our digital presence generates a data footprint that is currently being stored in big tech’s centralized silos. As a whole, these use...

From technological breakthrough to philosophical defiance, the topic of AI has always sparked intense debates ever since Alan Turing & John McCarthy advanced this branch of computer science. One might argue that this was caused by expectations overwhelmingly surpassing technological capabilities. However, the recent public release of ChatGPT has rekindled former sci-fi apocalyptical scenarios, eve...

DeFi lending protocols operate accordingly to their smart contracts and are perfect examples of ‘Code is law’, even if some recent exploits have not quite abided to this harsh truth. From well established protocols to degenerate DeFi farms with astronomic APYs, they all mainly use liquidity pools. Morpho Labs proposes a peer-to-peer approach that operates on top of another protocol’s liquidity poo...

2022 has proven time after time that centralised entities are prone to multiple points of failure, intentional or not. Decentralised finance (DeFi) addresses these, but the user experience has often been lacklustre compared to that from centralised finance (CeFi). Exchanges are the backbone of any market, but high throughput is required in order to ensure that both makers and takers can proficient...

The recent advancements of layer 2 scaling solutions, especially zero-knowledge rollups, led to a complete redesign of Ethereum’s scalability roadmap. As a result, the initial concept of sharding the execution layer was abandoned and replaced by the idea of data sharding. This proposal, named after its author, is know as Danksharding. EIP-4844 is also referred to as proto-danksharding as it sets t...

While Part 1 (#476) focused more on the general landscape of the ZK ecosystem, covering team updates and developments, in this episode, we take a closer look at specific use cases for ZK proofs and if the focus has shifted from privacy to blockchain scalability. Moreover, as the dusk of 2022 introduced chatGPT to the world, it seems only fitting to explore ZKP integrations in machine learning (ML)...

Blockchains are immutable record keepers, storing information about every transaction ever recorded. However, this attribute comes at a cost: as more and more transactions occur, so does the size of the record expands. In turn, the hardware requirements for running a node increase which ultimately affects decentralization. Another aspect frequently criticized is how transactions are being processe...

When discussing the widespread adoption of true, peer-to-peer decentralization, one could easily identify various social and political obstacles. However, there is also an often overlooked technological impairment as the underlying architecture of computer networks was not designed to achieve global-scale decentralization. Ideally a complete restructuring would be necessary, from applications and...

As crypto adoption increases, so does the pressing need for blockchain scalability. Monolithic blockchains provide data availability, consensus and execution on a single, base layer, which makes scaling them a difficult endeavour. Multiple layer-2 (L2) scaling solutions have been proposed to address computation and/or data availability, but they reach the same design bottlenecks: limited bandwidth...

This year has been quite a rollercoaster for the crypto industry. From the long-awaited success of the Ethereum Merge to the spectacular collapse of FTX, this year has been full of lessons, resilience, and insights. This is also one of a few bear markets where activities and developments continue to feel vibrant across the board, while long-term adoption and regulations seem evermore uncertain. Wi...
