¡Lo voy a decir claro!Para tener una carrera profesional sólida como Blockchain Developer, necesitas tener conocimientos de software "tradicional".Estamos en plena transición de la Web2 hacia la Web3, y si, vas a tener que usar todos los conocimientos de desarrollo (y lo más importante) y de arquitectura de sistemas Web2 para poder trabajar en proyectos profesionales Web3Hablando de tecnologías, impera todo lo que tiene que ver con EVM (Ethereum Virtual Machine), tanto para sistemas descentralizados privados (Hyperledger) o públicos (Ethereum).También hay que mencionar, que existe una nueva generación de Blockchains que se está desmarcando de EVMPara todo esto anterior, necesitas aprender: JS, Solidity y Rust (en este orden)

Blockchain development expertise requires proficiency in languages like Solidity, JavaScript, Python, or Go, and experience with platforms such as Ethereum, Hyperledger, or Binance Smart Chain. Essential skills include developing, testing, and debugging smart contracts—self-executing agreements on the blockchain. Understanding best practices for security, scalability, and interoperability is fundamental. In my role, focusing on these competencies has enabled the delivery of robust blockchain solutions, enhancing operational efficiency and security. This experience underscores the importance of a solid foundation in blockchain development principles for creating innovative and sustainable applications.

Designing a blockchain-enabled project has some quirks compared to the traditional, web2 applications. Ironically, they arise from the primary advantages of blockchain - immutability and decentralization. As an example, try designing a simple file storage app the old, web2 way, and then try to change it into something that takes full advantage of the blockchain ecosystem. This will be a fun exercise!

Designing blockchain solutions requires a deep understanding of user and stakeholder needs, a skill I've honed in managing diverse IT projects. It involves analyzing problems, defining requirements, and crafting an architecture that balances performance, functionality, and usability. My experience has taught me the importance of selecting the right blockchain platform and consensus mechanism, considering their impact on the solution's overall efficacy. This process is not just technical but also highly strategic, necessitating clear communication of design decisions through diagrams and specifications.

so it's totally depend on the domain that you want to work on blockchain..most interesting thing about bitcoin to me was engagement of a huge domain of people . like software developers , electric engineer , logistics , hardware developers , traders , economists , marketers and community builders ... it was infiltrate on all experts and domains ! so you have a huge chance to explore and research in blockchains . so when you find your domain to interact with blockchains you can find right sources to research about blockchains in your OPV .

Researching blockchain involves staying abreast of emerging technologies and their implications for industry and society, a principle that aligns closely with my role as CTO. This skill requires not only tracking innovations but also critically assessing information for validity and reliability, mirroring the due diligence necessary in IT management. My experience in disseminating complex information across teams and stakeholders resonates with the need to share research insights effectively. Whether through reports, presentations, or publications, the ability to synthesize and communicate findings is crucial, underscoring the interconnectedness of technology management, software development, and the dynamic blockchain landscape.

In my role as CTO, collaboration within the blockchain domain is paramount, reflecting a core tenet of technology management and Scrum. Engaging with blockchain communities not only fosters knowledge growth but also mirrors the collaborative essence of Lean Software Development. My experience in leading diverse IT teams and interfacing with stakeholders from various sectors echoes the skill's emphasis on effective communication and teamwork. By actively participating in forums, events, and projects, one leverages collective intelligence, a practice that underpins successful software development projects and innovation in blockchain technology, emphasizing the importance of a community-driven approach in technological advancements.

Essential blockchain skills go beyond technical proficiency, emphasizing the importance of teamwork and networking. Effective engagement in blockchain networks and events, both online and offline, promotes knowledge sharing and industry expansion. To understand the distinct perspectives of various groups, such as developers, clients, and regulators, efficient communication is essential. Working cohesively in teams, coordinating work, and using collective intelligence exemplify the collaborative spirit required for success in the blockchain area.

To master the blockchain mindset, delve into the foundational scriptures such as Satoshi Nakamoto’s seminal Bitcoin whitepaper and Vitalik Buterin’s visionary Ethereum manifesto, absorbing the ethos of decentralization and the mechanics of consensus. Engage with the multifaceted tapestry of blockchain applications, from the golden vaults of finance to the supply chains woven with transparency. Finally, pledge your allegiance to a DAO, navigating its governance labyrinths to learn the balance of power and participation.

Blockchain represents a paradigm shift emphasising decentralisation, transparency, and trust. It eliminates intermediaries, enabling peer-to-peer transactions and collaborations. Transparency is ensured through an immutable ledger, enhancing accountability and enabling new forms of auditability. Trust is established via cryptographic techniques and consensus mechanisms - ensuring blockchain integrity and immutability against malicious actors - reducing the risk of fraud and empowering global transactions. At its core, blockchain is a decentralised database of linked blocks containing verified transactions, added through mining or validation.

Knowledge of consensus algorithms: Familiarity with various consensus mechanisms such as Proof of Work (PoW), Proof of Stake (PoS), Practical Byzantine Fault Tolerance (PBFT), and Delegated Proof of Stake (DPoS), and their implications on network security, decentralization, and energy efficiency. Understanding the trade-offs involved in selecting consensus mechanisms based on the specific requirements of blockchain projects, such as transaction throughput, latency, and energy consumption.Understanding of regulatory frameworks and compliance requirements relevant to blockchain applications, including data privacy laws, financial regulations, and anti-money laundering (AML) policies.

Understanding how the networks and ecosystems work is one part of the skillset. The other, just as important, skill is understanding where blockchain can add the most value to a project. Not everything will benefit from adding a blockchain to it. Applications that need speed and response time are, obviously, not suited for blockchains. However, in situations where time is not as crucial a factor as precision and the data being maintained, blockchain systems can add value by providing trust in the validity of the data.
