A new scaling and privacy layer for #Bitcoin has been released: 𝗠𝗲𝗿𝗰𝘂𝗿𝘆 𝗟𝗮𝘆𝗲𝗿

Here’s what you should know about it👇

The Mercury Layer is a relatively new system designed to streamline Bitcoin transactions, making them faster and more cost-effective. Functioning as a 'second layer' over Bitcoin's base layer, it offers a way to transfer bitcoin 𝘸𝘪𝘵𝘩𝘰𝘶𝘵 𝘵𝘩𝘦 𝘶𝘴𝘶𝘢𝘭 𝘤𝘰𝘯𝘧𝘪𝘳𝘮𝘢𝘵𝘪𝘰𝘯 𝘵𝘪𝘮𝘦𝘴 𝘰𝘳 𝘧𝘦𝘦𝘴, much like other layer 2 protocols like Lightning, Liquid, and ARK.

When you transact in Bitcoin, you're essentially exchanging digital units of bitcoin called UTXOs (Unspent Transaction Outputs). Think of a UTXO as a digital version of cash, except it can be any amount, and not limited to 1s, 5s, 10s, etc. 𝗧𝗵𝗲 𝗠𝗲𝗿𝗰𝘂𝗿𝘆 𝗟𝗮𝘆𝗲𝗿 𝗲𝗻𝗮𝗯𝗹𝗲𝘀 𝘆𝗼𝘂 𝘁𝗼 𝘁𝗿𝗮𝗻𝘀𝗳𝗲𝗿 𝘁𝗵𝗲𝘀𝗲 𝗨𝗧𝗫𝗢𝘀 𝗱𝗶𝗿𝗲𝗰𝘁𝗹𝘆, akin to handing cash to a friend, without recording every transaction on Bitcoin's timechain.

What makes Mercury stand out is its method for changing ownership of UTXOs. It cleverly uses divided parts of a digital key, akin to a shared secret. This key is essential for a user to prove their ownership of the UTXO. By altering parts of this key, 𝘆𝗼𝘂 𝗰𝗮𝗻 𝘁𝗿𝗮𝗻𝘀𝗳𝗲𝗿 𝗼𝘄𝗻𝗲𝗿𝘀𝗵𝗶𝗽 𝘀𝗺𝗼𝗼𝘁𝗵𝗹𝘆, avoiding the need to broadcast the transaction to the world.

Mercury also incorporates backup transactions as a safety net. These act like emergency measures, allowing you to reclaim your Bitcoin, 𝗲𝘃𝗲𝗻 𝗶𝗳 𝘁𝗵𝗲 𝗦𝘁𝗮𝘁𝗲𝗰𝗵𝗮𝗶𝗻 𝗘𝗻𝘁𝗶𝘁𝘆, 𝗼𝗿 𝗦𝗘, 𝗱𝗼𝗲𝘀 𝗻𝗼𝘁 𝗰𝗼𝗼𝗽𝗲𝗿𝗮𝘁𝗲. This system ensures that only the current owner can use these backup measures, thereby preventing any fraudulent claims to your bitcoin.

The process of using Mercury begins with an on-chain transaction of sending your UTXO to an address where 𝘣𝘰𝘵𝘩 𝘺𝘰𝘶 𝘢𝘯𝘥 𝘵𝘩𝘦 𝘚𝘌 have shared private key control. When transferring your UTXOs within the system, Mercury updates the secret key. Each time it's transferred, an updated emergency plan is created for the new owner.

Mercury ensures transaction integrity by counting how many times it assists in transfers. However, it does not delve into transaction details, 𝘁𝗵𝘂𝘀 𝗺𝗮𝗶𝗻𝘁𝗮𝗶𝗻𝗶𝗻𝗴 𝘆𝗼𝘂𝗿 𝗽𝗿𝗶𝘃𝗮𝗰𝘆 𝘄𝗵𝗶𝗹𝗲 𝘀𝘁𝗶𝗹𝗹 𝘃𝗲𝗿𝗶𝗳𝘆𝗶𝗻𝗴 𝘁𝗿𝗮𝗻𝘀𝗮𝗰𝘁𝗶𝗼𝗻 𝗹𝗲𝗴𝗶𝘁𝗶𝗺𝗮𝗰𝘆.

When you're ready to exit Mercury back to Bitcoin’s base layer, you can close your transaction at will, finalizing it on Bitcoin's timechain. This closure 𝘦𝘯𝘴𝘶𝘳𝘦𝘴 𝘵𝘩𝘢𝘵 𝘵𝘩𝘦 𝘜𝘛𝘟𝘖 𝘤𝘢𝘯'𝘵 𝘣𝘦 𝘤𝘪𝘳𝘤𝘶𝘭𝘢𝘵𝘦𝘥 𝘸𝘪𝘵𝘩𝘪𝘯 𝘔𝘦𝘳𝘤𝘶𝘳𝘺 𝘢𝘨𝘢𝘪𝘯, keeping the process orderly and secure.

However, 𝗲𝘃𝗲𝗿𝘆𝘁𝗵𝗶𝗻𝗴 𝗰𝗼𝗺𝗲𝘀 𝘄𝗶𝘁𝗵 𝘁𝗿𝗮𝗱𝗲𝗼𝗳𝗳𝘀, so it should be noted that Mercury requires 𝘴𝘰𝘮𝘦 trust in the system’s main coordinators, the Statechain Entities. While 𝘚𝘌𝘴 𝘤𝘢𝘯'𝘵 𝘮𝘰𝘷𝘦 𝘧𝘶𝘯𝘥𝘴 𝘰𝘯 𝘵𝘩𝘦𝘪𝘳 𝘰𝘸𝘯, their role is crucial, and their security and integrity are paramount.

Another tradeoff is 𝘁𝗵𝗲 𝗿𝗶𝘀𝗸 𝗼𝗳 𝗻𝗲𝘁𝘄𝗼𝗿𝗸 𝗰𝗲𝗻𝘁𝗿𝗮𝗹𝗶𝘇𝗮𝘁𝗶𝗼𝗻. If a few SEs begin to dominate the Mercury system, it could centralize a significant portion of transaction facilitation. This would diverge from Bitcoin's decentralized ethos, so 𝘪𝘵’𝘴 𝘪𝘮𝘱𝘦𝘳𝘢𝘵𝘪𝘷𝘦 𝘵𝘩𝘦𝘳𝘦 𝘣𝘦 𝘢𝘴 𝘮𝘢𝘯𝘺 𝘚𝘌𝘴 𝘢𝘴 𝘱𝘰𝘴𝘴𝘪𝘣𝘭𝘦.

The Mercury Layer introduces simplicity and enhanced security to Bitcoin transactions. It makes transferring bitcoin 𝘢𝘴 𝘦𝘢𝘴𝘺 𝘢𝘴 𝘦𝘹𝘤𝘩𝘢𝘯𝘨𝘪𝘯𝘨 𝘤𝘢𝘴𝘩, as long as concerns around trust, privacy, and centralization are mitigated. Mercury highlights Bitcoin's ongoing evolution, and is a further reminder that we're all still very, 𝘷𝘦𝘳𝘺 early.
