Bitcoin: Security Concerns After the Halving

The latest Bitcoin halving, which occurred in May 2020, has raised concerns among experts about the network’s security. Nikita Zhavoronkov, lead developer of Blockchair, a cryptocurrency block explorer, has warned that the halving could lead to a reduction in Bitcoin’s security budget.

What is Bitcoin’s Security Budget?

The security budget of Bitcoin refers to the amount of money that miners receive in subsidies and fees. This budget is essential for maintaining the network’s security, as it incentivizes miners to continue verifying transactions and adding new blocks to the blockchain.

The Impact of the Halving on the Security Budget

The halving reduces the amount of Bitcoin that is issued to miners as a reward for verifying transactions. This means that the security budget of Bitcoin is also reduced by half. Zhavoronkov warns that if the network does not experience sustained high fees, the security budget will not be sufficient to maintain the network’s current level of security.

Three Possible Solutions

Zhavoronkov suggests three possible solutions to address the security budget issue: scaling Bitcoin on-chain to allow for more transactions and higher fees; changing the monetary policy of the network to remove the 21 million BTC issuance limit; or changing the Bitcoin consensus system from proof-of-work to proof-of-stake.

Criticisms of Zhavoronkov’s Concerns

Some critics have argued that Zhavoronkov’s concerns are overblown. They point out that while the number of bitcoin produced has dropped, its price has simultaneously increased. This means that the security budget, measured in BTC, has not actually decreased.

Conclusion

The security of Bitcoin’s network is paramount to its success. The halving has raised concerns about the network’s ability to maintain its current level of security. While there are differing opinions on the severity of the issue, it is clear that the Bitcoin community needs to find a way to offset the security impact of the halving.
