We were looking for an offshore company partner and finally we found SotaTek and had started working with them since September 2022. ( ... ) They helped us pay down the technical debt and also accelerate our development. Without SotaTek, we wouldn't be able to actually handle so many technical initiatives. Thanks to SotaTek, we were able to deliver all of them in time. So if you are looking for an offshore engineering team. I'd recommend SotaTek.

Lemon Healthcare aims to extend its presence beyond South Korea into Southeast Asia. For that reason, we decided to choose SotaTek. SotaTek is already making a name for itself in Vietnam as a professional outsourcing company. We needed the ability of SotaTek. Through this, we intend to localize and expand smart hospital ERP in Southeast Asia and help both companies grow.

It feels natural to have a partner with the same mindset as us, who we can always trust and ensure that nothing is impossible.

FAQ

Blockchain is a Decentralized Distributed Ledger, or in more simple words, a type of decentralized database. Every transaction will be recorded in the ​blocks​ and linked together with the chain​ in which it uses the hash algorithm and then ​distributes​ it to every node in the network. Each data or transaction is digitally signed to ensure its authenticity and makes it immutable, so the node itself and the existing transactions within the blocks are assumed to be of high integrity.

Blockchain development commonly involves programming languages like:

  • Solidity (for Ethereum smart contracts).
  • JavaScript (for front-end and back-end integration).
  • Python (for blockchain-related applications and smart contracts).
  • Go (Golang) (used in Hyperledger and Ethereum).
  • Rust (for Solana and Polkadot blockchain development).
  • C++ (used in Bitcoin and other blockchain protocols).

Each language serves specific blockchain needs depending on the project or platform.

The four types of blockchain are:

  • Public Blockchain: Open to anyone and fully decentralized (e.g., Bitcoin, Ethereum).
  • Private Blockchain: Restricted access, controlled by a single entity.
  • Consortium Blockchain: Managed by a group of organizations.
  • Hybrid Blockchain: Combines elements of both public and private blockchains, offering flexibility in control and access.

Blockchain offers several transformative advantages:

  • Enhanced Security: Its decentralized nature and cryptographic algorithms make data manipulation nearly impossible, ensuring high security.
  • Immutability: Once recorded, data cannot be altered, fostering trust among users.
  • Cost Reduction: Eliminates middlemen, reducing transaction and administrative fees.
  • Decentralized Control: Distributed networks prevent centralized power, minimizing risks of fraud or manipulation.

These features position blockchain as a game-changer in various sectors, particularly those requiring secure, transparent, and efficient processes.
