Odaily Planet Daily News Web3 education platform Open Campus announced that it will soon sell the principal node (Principal Node) of EDU Chain. EDU Chain is a Layer3 blockchain designed by Open Campus specifically for education. The principal node sale will include pre-sales and public sales, and details will be announced in June. The principal node is a verification node on the EDU Chain, which is used to review and verify the authenticity of transactions before they are confirmed on the chain, thereby protecting the network. The principal node sale of EDU Chain adopts a tiered approach to encourage early participation, and the node price increases at each level in multiple levels. A portion of the sequencer fee will be paid to the principal node operator to thank him for helping to verify transactions on the EDU chain, and the principal node can be transferred one year after the sale.
