What is the next Cryptocurrency technology? The Cross-Chain is a replacement for the Blockchain?
Cross-chain transactions. There are swap, conversion, and some wallets allow you to do this. The precious point is you have to pay more expensive fee if you want to have fast feature. Swap, conversion, cross-chain transactions, you can get them but afford for more charges.
I don't want to use them because of fee and uncertainty of security and privacy for my transactions and funds.
If I want to have privacy, I can use Bitcoin Coin Join transactions or Monero if I am really obsessed with privacy. Doing cross chain transactions through smart contracts is risky and don't make me feel safe.
