BitTorrent’s evolution: From P2P file sharing to blockchain innovation

Launched in 2001, BitTorrent was a game-changer in the world of peer-to-peer (P2P) file sharing and accounted for one-third of all internet traffic

Launched in 2001, BitTorrent was a game-changer in the world of peer-to-peer (P2P) file sharing and quickly became a major player in the internet landscape. Within a few years of its initial release, BitTorrent was responsible for one-third of all internet traffic. However, as the internet continued to evolve, the limitations of BitTorrent’s incentive structure became increasingly apparent, leading to a decline in its usage.

In 2018, BitTorrent was acquired by Tron, marking the beginning of a new chapter in its evolution. Tron expanded BitTorrent’s scope beyond file sharing by integrating blockchain technology, leading to the creation of new systems such as the BitTorrent Filesystem (BTFS) and, more recently, the BitTorrent Chain (BTTC). The BitTorrent (BTT) token serves as the utility token for each of these networks.

BTFS is a decentralized file storage system that rewards users with BTT tokens for long-term file storage. It addresses the limitations of the original BitTorrent protocol, which relied heavily on altruism. Under the original protocol, users would often cease seeding files after their downloads were complete, a phenomenon known as the tragedy of the commons. BTFS, on the other hand, motivates miners to maintain files over extended periods by offering BTT token rewards as an incentive.

Currently, over eight million storage miners are active on the network, and more than six pebibytes of data have been stored. The successful implementation of BTFS laid the groundwork for further blockchain integration in the BitTorrent ecosystem and the development of BTTC.

BTTC was created to address the need for seamless asset transfers between different blockchain networks. It is designed as a scalable interoperability layer that connects Tron and EVM-based chains. BTTC achieves high transaction throughput and low fees by leveraging a network of proof-of-stake sidechains derived from Cosmos’ Tendermint software stack. Validators stake BTT on Tron, and slashing conditions are applied to ensure the integrity of the network.

BTTC facilitates asset transfers across different chains, including Tron, Ethereum and the BNB Smart Chain. For these transfers, BTTC employs a lock-and-mint model, where tokens are locked on one chain and minted on BTTC. The network processes approximately 7,000 transactions per second with a block time of three seconds. Average gas fees are below $0.01. Security and reliability are maintained by 12 active validators, supported by over 6,200 stakers (figure 1).

To further enhance the user experience, BTTC incorporates a relayer service that accelerates the withdrawal of assets across different blockchain networks. Under normal conditions, withdrawing assets from BTTC to another blockchain can incur a delay of 15 to 30 minutes due to the need for checkpoint validation. Relayers are independent service providers who facilitate faster withdrawals by handling the cross-chain communication and pre-paying the necessary gas fees on the target chain. They do this in exchange for a service fee, which is typically set at 120% of the gas cost for the withdrawal transaction.

The backbone of the ecosystem is the BTT token, which is integral to both BTFS and BTTC’s operations. It has a fixed supply of 990 trillion tokens, following a redenomination from the original 990 billion tokens in 2022 (figure 2).

Each year, approximately 7 trillion BTT tokens are distributed as staking and validation rewards, which constitutes 0.7% of the total BTT supply. This distribution encourages active participation from users, offering an attractive annual percentage yield of 17.65% for those who choose to stake their BTT tokens.

Currently, 39.9 trillion BTT are staked, which is 4% of its total supply. Apart from staking, BTT also serves as the primary currency within the BTFS to reward storage miners who store data on the network. The BTFS system generates around 7 billion BTT in daily organic protocol revenues, and miners receive incentives of about 7.5 billion BTT daily.

Looking ahead, BTTC is expected to play a central role in Tron’s upcoming initiatives, especially its integration with the Bitcoin ecosystem. Future developments include increasing the availability of wrapped Bitcoin assets on the Tron and BTTC networks, collaborating with Bitcoin layer-2 projects and creating a layer-2 solution that integrates Tron, BTTC and Bitcoin. This will allow Tron and BTTC to tap into Bitcoin’s security and liquidity with the speed and cost advantages of BTTC’s proof-of-stake system.
