As Netflix’s squid game took the top spot in popularity, the Korean traditional game called squid game has became popular. I looked for related books and articles to share how to play the game with you.   The shape of the game almost resembles a squid, which is divided into 5 parts. (Names of the parts are different from actual  functional parts of a real squid, but does not matter as it is just a game)  – Each team members consist of around 5 to 6. – Teams   are   positioning as below   – There should be two teams;  Attacking Team and  Depending Team – There are safe zones where the attacking team can rest: Head, Space and Tail.(Except for the body, everything else is the safe zone for the attacking team.) Therefore, the persons whose both feet touch the floor are to be out! – The defending team cannot enter that safe zones. – The only place the persons can enter inside is the tail part, which is the entrance to the body. Only though the tail, ...

I don't know what the reaction will be like in foreign countries, but Korea's reaction to the squid game is mixed. There was a good column about the squid game, so I translated it. 😵 This contains a number of spoilers about the drama "Squid Game". "Squid Game", a random survival game that is consistent only with compassion for middle-aged men.  - W e Geun-woo  Is there a need to listen to the story of a villain who contradicts himself? I should start writing with a spoiler. In the last episode of Netflix's original series "Squid Game", which was released on September 17, Oh Il-nam (Oh Young-soo), who people thought was a game participant but was actually a host of the game, tells game winner Sung Ki-hoon (Lee Jung-jae) that the reason he did it was because of his boredom in life. In response, Sung Ki-hoon is angry, saying, "Did you make people do that for fun?" However, a completely different question arises from the perspective of v...

What is Off-Chain?   Off-chain is not the main blockchain system, but transactions occur outside. Through this, it is possible to solve the scalability problem that could not be solved on-chain. Offchain records only core data on the blockchain, and at this time, data that needs high speed is recorded on the central server of the DApp, not the blockchain. Offchain has advantages such as low fees, high speed, and high transaction throughput. However, there is also a disadvantage, which is that the transaction details recorded in the off-chain cannot be fully trusted. A representative method for solving the off-chain scalability problem is a lighting network. The Bitcoin protocol takes an on-chain payment method that records all transactions generated in the network on the blockchain. This takes a very long time to verify because it stores all the transaction data in the block. Therefore, delays in confirmation occur, and fees paid to miners naturally become expensive. In the end, Bi...

What is On-Chain? On-chain is a transaction written on a blockchain network. All on-chain transaction information is included in the block, and recorded transactions cannot be permanently deleted. Representative examples of on-chain are Bitcoin and Ethereum, which form their own networks, and all transactions in the blockchain are recorded and disclosed to all users.  However, there is a possibility of various problems to rely solely on on-chain. There are  speed  problems that take a long time for transactions to be confirmed on the network after the transaction occurs,  privacy issues  that all transactions in the blockchain are disclosed to everyone,  cost issues  that incur payment costs to miners when verifying transactions, and  scalability issues  such as low TPS. In other words, the on-chain lost its speed instead of gaining high stability. A representative method for solving the scalability problem of the on-chain is the big block. C...

What is TPS?   TPS (TPS) stands for Transaction per Second, and refers to the number of transactions that can be processed per second. 1 million TPS refers to the speed at which 1 million transactions can be processed per second. TPS can be increased through centralization, but in that case, the purpose of decentralization, the original purpose of the blockchain, is undermined. Joseph Lubin, founder of Consensys, created the concept of DTPS by multiplying TPS by the Decentralization Quotient (DQ). DTPS is a decentralized TPS index. Like I said, TPS is an indicator of how many transactions a blockchain network can handle per second. Remittances of some coins are not processed immediately and take several minutes, which is all caused by a lack of TPS compared to the number of transactions. Therefore, coins that require fast transaction processing, such as payment services, continue to strive to increase TPS.  TPS may vary depending on not only the design of blockchain software, ...
