Blockchain Essentials: Crash Course on the Technology
in progress for now
A blockchain is a type of distributed ledger technology (DLT) that consists of growing list of records, called blocks, that are securely linked together using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves). The timestamp proves that the transaction data existed when the block was created. Since each block contains information about the previous block, they effectively form a chain (compare linked list data structure), with each additional block linking to the ones before it. Consequently, blockchain transactions are irreversible in that, once they are recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks.

Success in Maths for College - High School - University levels⭐⭐⭐⭐⭐
👨🎓 With 4 years of experience in distance education, I am a mathematics teacher specializing in support lessons and private lessons. I also teach physics and chemistry as well as scientific subjects in general.
I hold a Master's degree in Operational Research (Applied Mathematics) and I have been teaching private lessons for more than three years, mainly mathematics for middle and high school levels.
✏ I have taught students from different schools, whether public, private, following the French program (mission), Belgian, Swiss, Spanish (students from French-speaking or English-speaking Spanish schools) or American. In summary, all French or English programs.
✏ I support students from A to Z in all stages of their learning, using a simple, new generation and effective methodology: explanation of lessons, summary of lessons, application and deepening exercises, etc.
✏ I also prepare students for exams and competitions.
✏ I also support students with their homework (homework help).
✏ All my students have made extraordinary progress and achieved their goals, with grades of 16, 17, 18 or 19 out of 20.
Sessions usually take place as follows:
1️⃣ The first sessions are mainly intended to assess the level of the student in order to determine the shortcomings noted.
2️⃣ Then we make a plan to fill those gaps: number of hours of work required, parts of the lessons to focus on, lots of training and development exercises, etc.
3️⃣ We make sure to stay up to date with the student's class teacher to track their progress and align our work with what is being taught in class.
4️⃣ Then I provide exams similar to what may be offered in class.
5️⃣ Upon request, I write a monthly report to keep parents informed of their child's level throughout the course.
I also adapt my methodology according to the needs of each student, which means that everyone has a personalized working method adapted to their needs!
I also offer crash courses for those preparing for the start of the school year, so that they start the year well prepared 💪 and with a head start on the program.🧠

TRAINING TO EMBODY EFFECTIVE MANAGERIAL COMMUNICATION IN THE PROFESSIONAL FRAMEWORK➤ Being a good manager is also being a good communicator. After all, a strategy can only be put into practice if you show yourself capable of interacting with your employees, of being a source of inspiration for them and of listening to their concerns. Unfortunately, not all managers naturally excel in this role and their difficulties in asserting themselves as true leaders is often attributable to their difficulties in communicating.
➤ The objective would then be to explore together the areas of improvement in terms of communication know-how. And managing effectively requires specific and advanced know-how.
➤ In fact, managerial communication corresponds to the interactions between the management of the company and the organization and more specifically, between the manager and his team. This executive is in charge of transmitting information and directives from higher hierarchical levels, supporting internal communication, distilling messages related to his own management to obtain the commitment of his team, all while transmitting a message effectively.
➤ This exercise can therefore be tricky: this is why it is important to choose the right mediator in order to be well supported, not only to be understood by those around him, but also to carry out his mission.
➤ What to communicate? When ? Whose ? These questions will find an answer in the consistency of the actions undertaken. Good managerial communication will thus aim to exchange / dialogue effectively with its employees, maintain a close link between the different layers of the company, bring human relations back to the heart of the company, establish a climate of trust and good team cohesion, motivate by inspiring.
➤ In short, each session combines techniques & practice exercises adapted to your everyday situations (filmed with your agreement in order to be reviewed, commented on, decoded together live), so that you can put them into practice immediately, and this from the 1st session.
Statistically, the progression following these private sessions is quickly noticeable, from 2 or 3 sessions *. (* study 2020).
➤ THE TRAINER:
Trained in Grande Ecole post-preparatory classes & Ivy League university in the United States, our teacher has specialized and has been working for more than 15 years, in Europe and North America, in the field of communication , in reputable international public and private establishments, intervening in forums and conferences, and oriented on two axes: training and coaching, with pedagogy and careful methodology as key words.
