Bitcoin gets an upgrade this month. It is known as the Taproot upgrade.
In short, it is a soft fork of Bitcoin in order to make transactions cheaper, more private, more scalable, and with additional smart contract functionality.
This upgrade has been proposed since 2018. It took a while to achieve over 90% acceptance rate from the mining community. This upgrade highlights two key features:
- Digital signature upgrade:
When Satoshi Nakamoto first created Bitcoin, he chose Elliptic Curve Digital Signatures (ECDSA), which were already widely used, well-understood, secure, and open-source.However, the newly adopted Schnorr signatures are known for their simplicity and efficiency in generating short signatures. This upgrade will make signatures size smaller, transact faster, and bring down transaction fees.
- Taproot system upgrade:
The Taproot upgrade uses the Merkelized Abstract Syntax Tree (MAST) system to make complex transactions such as multisig transactions indistinguishable from basic transactions. This offers more privacy when using Bitcoin multisig, as it will “cloak” all the moving parts of a complex transaction into a simple one.Compared to a software update from a centralized entity, blockchain updates are much more difficult as it requires consensus among all the network participants. The new improvements will allow developers to create more extensive Bitcoin applications that take up less space on the network, and open up the potential of Bitcoin to have smart contracts running on the network.
El Salvador President Nayib Bukele announced plans to issue a $1 billion “Bitcoin Bond” with a 10-year
maturity. Half of the money raised will be used to purchase Bitcoin, and the rest will fund construction of a new
”Bitcoin City” along the Gulf of Fonseca near a volcano.
The bond will offer a 6.5% coupon annually; the annualized yield back to investors could reach 146% in the 10th year, according to Blockstream projections. Compare that with the benchmark 10-year yield on El Salvador’s outstanding government bonds, currently around 13% — this Bitcoin-backed investment is considered “less risky” than the country’s sovereign bond.
The City of Miami will soon pay a Bitcoin-denominated yield to residents who stake the MiamiCoin token, an instrument that may eliminate the need for city taxes in the future.
