EverMsg is a browser for exploring messages permanently stored on the Bitcoin blockchain using OP_RETURN transactions. These messages are immutable and will exist as long as Bitcoin exists. Our platform indexes and displays these messages in an easy-to-read format.
OP_RETURN is a Bitcoin script opcode that allows users to embed up to 80 bytes of arbitrary data into a transaction. This data becomes permanently recorded on the blockchain, making it ideal for storing small messages, timestamps, or proofs.
Yes. Once an OP_RETURN message is confirmed in a Bitcoin block, it becomes part of the immutable blockchain. OP_RETURN data is stored forever because it's embedded directly into the transaction. As long as Bitcoin exists, these OP_RETURN messages will remain accessible.
You can create an OP_RETURN transaction using Bitcoin wallets that support this feature or through specialized services. The message will be permanently recorded once the transaction is confirmed by miners.
No. OP_RETURN data on the blockchain is immutable by design. Once an OP_RETURN message is recorded in a Bitcoin transaction, it cannot be edited, deleted, or censored by anyone, including the original sender.
EverMsg supports messages in any language. We provide automatic language detection and filtering for English, Chinese, Japanese, Korean, and Spanish interfaces.
Yes, browsing and reading OP_RETURN messages on EverMsg is completely free. However, creating new OP_RETURN transactions requires a Bitcoin transaction fee paid to miners.
Our database scans the Bitcoin blockchain regularly for new OP_RETURN transactions. New OP_RETURN messages typically appear within minutes of being confirmed on the network.
