logion blockchain pitch deck

logion is a DAO blockchain network in which nodes are owned by EU Judicial Officers.

Extract from the White paper:

Today, either a company, a public institution or an individual willing to build alternative models on a blockchain infrastructure experiences a number of challenges. Current environments are not adapted for mainstream adoption.

Indeed, where to turn to in case of litigation over operations completed on blockchains today? Who is responsible for malicious behaviors, breaches or data manipulations? Blockchains and the question of liability remains a very delicate question over which users have little or no security.

In the same vein, how to ensure that this disintermediate network is effectively not in the hands of a few actors? With the main popular consensus mechanisms, the risk of nodes concentration is real. As a result, new models cannot be built on resilient infrastructure.

In addition, how to build viable models with fees that may be, or that are, subject to fluctuations with the network demand?

Also, how can you prove the authenticity of a data record in the blockchain today? You can show the stamping, but what about the probative value of this electronic record? How does it differ from another means of evidence?

Who can provide the link between operations or data from the outside of the blockchain to the inside of the blockchain? Computers? Programmed systems? How is their authenticity guaranteed?

Considering these challenges, how can we build new paradigms on environments that do not ensure the construction of stable and secure models?

Here is our answer.

By bridging the gap between the real world and its rules, and the virtual world and its efficiency.

With logion, we put humans at the heart of the solution. We built a hybrid blockchain network with European Judicial Officers playing the role of validators. As they are sworn in, they offer legal guarantees and ensure a high security level to users.

This blockchain infrastructure is the backbone of logion ecosystem. A collaborative tool opening the doors to alternative and decentralized models.

Forming an integral part of the environment, a decentralized storage system and independent multi-signature wallets are connected to the blockchain. One network, three layers managed by trusted partners: blockchain nodes, decentralized storage, secure wallets.

We are also convinced that a distributed network should be decentralized from the maintenance of its infrastructure to its governance. For this reason, all decisions affecting the network are taken by governance members being validators, investors and the core team.

With an on-chain governance structure, logion is therefore a fully decentralized ecosystem.

On the road to Ethereum 2.0: a necessity, update road, two major improvements…

While Ethereum has brought about a whole new realm of possibilities due to its native token Ether (ETH) and its smart contract and tokenization capabilities, it is often faced with challenges such as network congestion, relatively low transaction times and throughput, large blockchain size and excessive electricity use for mining (all issues Bitcoin also shares).

This state has been even more recently highlighted by the success of the DeFi (Decentralized finance).

Ethereum was built on several stages, many of which have been implemented, but Serenity (Ethereum 2.0) is particularly important for the network and community because it will bring about some of the biggest changes in the network, including proof-of-stake and sharding updates.

Ethereum 2.0 is planned to launch in the second half of 2020, following its announcement in 2018 and launch delays in 2019 and 2020. The deployement will follow a step by step implementation model. 

Consensys website extract :

« Phase 0: In the first phase of Ethereum 2.0, the “Beacon Chain” will be implemented. The Beacon Chain stores and manages the registry of validators, and will implement the Proof of Stake (PoS) consensus mechanism for Ethereum 2.0. The original Ethereum PoW chain will continue to run alongside the new Ethereum PoS chain, ensuring there is no break in data continuity.

Phase 1: The second phase of Ethereum 2.0 will likely roll out in 2021. The primary improvement of Phase 1 is the integration of shard chains. Shard chains are a scalability mechanism in which the Ethereum blockchain is “split” into 64 different chains, which allows for parallel transaction, storing, processing of information. At its most conservative estimate it will enable 64 times more throughput than Ethereum 1.0, but it is designed to be able to handle several hundred times more data than Ethereum 1.0.

Phase 2: The third phase of Ethereum 2.0 will likely be launched in 2021 or 2022. This phase is currently less clearly defined than the above two phases, but will involve adding ether accounts and enabling transfers and withdrawals, implementing cross-shard transfers and contract calls, building execution environments so that scalable applications can be built on top of Ethereum 2.0, and bringing the Ethereum 1.0 chain into Ethereum 2.0 so that Proof of Work can finally be turned off. » 

The first stage is currently known as « Phase 0 » and will see the launch of the Beacon Chain (the heart of Ethereum 2), the blockchain on which the first iteration of Ethereum’s PoS consensus model will be implemented. 

The second stage, « Phase 1 » will bring the implementation of shard chains that are compatible with each other and can be used simultaneously. 

While these two stages will build the foundation of Ethereum 2.0 and the solutions for the congestion and scalability issues Ethereum is currently facing, these two stages will coexist with the current blockchain 1.0, and the two will only be merged in the third stage. 

During a « Phase 1.5. » (pre third stage), Ethereum 1.0 will coexist alongside 63 other blockchains, with the Beacon chain eliminating the need for token swaps for those that wish to remain on the original chain throughout the implementation of Ethereum 2.0. 

Once Ethereum 1.0 will be merged with Ethereum 2.0 – the third stage – the blockchain history will remain, with Ethereum 2.0 being considered as completely deployed. It is expected to happen by 2021.


About improvements… 

The sharding feature on Ethereum 2.0 will allow 64 chains to run in parallel, meaning that the transaction speed and throughput will be considerably increased. These chains will be interoperable, and users will be able to spend Ether across multiple chains. However, the burden of keeping the blockchain history will be distributed throughout the multiple chains, allowing the network to be more accessible while still secure. 

Proof of Stake (PoS) mechanism will offer more crypto-economic security combined with lower electricity consumption.


logion project, substrate and polkadot

logion is a project that aims to build a blockchain network (thanks to substrate technology and this development environment), a polkadot parachain, stable, clear, transparent, in which the nodes will be held by public and ministerial EU officers. This network will have first an operating cost advantage but will also offer very specific services:

  • an enhanced mode of proof for operations carried out using this network
  • an oracle’s service provided by certified professionals
  • legal services which will be complementary to the blockchain technology
  • trusted third party services

These services will be available for the entire ecosystem as a result of the interoperability potential offered by Polkadot.

In a nutshell, here’s how things are going.

Polkadot is a platform that allows distinct blockchains to transfer messages and exchange transactions, through a relay chain, turning them into a big multi-chain network. It provides networking and consensus layers that allow blockchain developers to focus on creating business logic with unique features and implementing it in a parachain.

The parachain (parallelized chain) is what allows private, public, and consortium blockchains to connect and scale.

Polkadot consists of many parachains with potentially different characteristics. Even non-blockchain systems or data structures could become part of the network. Even stand-alone blockchains as Bitcoin, Ethereum, and Tezos could be connected to Polkadot by developing an appropriate parachain.

logion will be a parachain, so an independent blockchain that provides own blocks. A parachain can have its own monetary system, its own logic, and its own interactions with third-party applications or separate blockchains. Parachains inherit security from the relay chain (Polkadot). They can also send messages and provide services to other parachains. Each parachain is connected to some validator for a certain period of time and is hosted with its own set of collators.

That’s how we’re going to build our blockchain network and services provider. We’ll start the first serious work this summer!

TechLawyer Academy will be launched in 2020!

With this academy and in partnership with Seraphin Legal (France), the aim is to develop the necessary skills to digital technology for legal professionals!

Legal professionals and services are today involved in an unavoidable digital transition process. Then, the question is, how best to manage these changes, for today, as well as tomorrow… Should we ask always the help of a third party or develop certain in-house skills? What would be the competencies required in order to remain competitive and strong in the face of the market? How to simplify the daily management, to save time, money and to improve efficiency. The TechLawyer ACADEMY brings essential skills together for you into a complete and coherent training.

The program will be intense with clear business focus:

  • General introduction
  • Legaltech project manager
  • Coding lawyer
  • Data lawyer
  • Cybersecurity lawyer
  • Privacy lawyer
  • Marketer lawyer
Sessions will take place in Luxembourg and Belgium in 2020.

HTTP 402, the precursor code of Ethereum and Tokens based network

Did you know the web was designed with payments in mind?

The HTTP code 402 was created and reserved for “Payment Required”. This class of status code is intended for situations in which the error seems to have been caused by the client for a no-payment situation.


Source : https://en.wikipedia.org/wiki/List_of_HTTP_status_codes#4xx_Client_Error :

« 402 Payment Required

Reserved for future use. The original intention was that this code might be used as part of some form of digital cash or micropayment scheme, as proposed, for example, by GNU Taler but that has not yet happened, and this code is not usually used. Google Developers API uses this status if a particular developer has exceeded the daily limit on requests. Sipgate uses this code if an account does not have sufficient funds to start a call. Shopify uses this code when the store has not paid their fees and is temporarily disabled. »


Today, it could be also really useful around any development of a Dapp on the Blockchain Ethereum. Indeed, it is impossible to deploy a contract and use the network without paying Gas. In case of a lack of credit on your wallet, the service could return you an HTTP_402 code.

More broadly, with the Blockchain, the web becomes a native internet currency.

So, we would witness the revival of this code, as a result of a major mutation of the web…



Distributed Ledger Technology and Smart-contracts: which incorporation into the usual Law?

Despite the fact that the Blockchain is recent, this technology already has many prospects and use cases in the following generic areas:

  • transfer of digital assets;
  • register;
  • smart-contracts.

Projects also support some concrete economic or real life developments (for example: dApp Ethereum, hyperledger), sometimes even in production context.

In the lack of a regulatory and a judicial environment, this use could therefore lead to legal difficulties or even litigation. Why? Because, to date, many questions remain open such as:

  • What probative force and what opposability regime should be given to data recorded in a Blockchain network?
  • Can a smart-contract be considered as a legal and/or a real contract?
  • How will a Judge handle a request concerning data originating from the Blockchain and/or a smart-contract?
  • How could we also introduce this technology into the legal field in order to ensure that it could be understood and embedded by legal professionals?

It would be useful to think about these and other questions soon, in order to prepare for tomorrow’s realities.

Indeed, the connection between the blockchain and the judicial reality has not yet been achieved. Who could say today that the Blockchain is practically incorporated by the judicial community and that a smart-contract is considered as a contract « sensu stricto ». There are therefore efforts to be made to make progress in a more appropriate direction.

This is precisely why, on the basis of some current insights, I would also like to explore constructive approaches, technical solutions also, that could help us move step by step towards a better matching of this technology with the needs of daily legal practice.

Technology must be made available to legal professionals. In this way, some challenges will be overcome more quickly. Then the blockchain could extend a little further into the real world…
